In this case, plaintiff, Denise Bryant, personal representative of the estate of her deceased aunt, Catherine Hunt, alleges that defendant Oakpointe Villa Nursing Centre, Inc. (Oakpointe), is liable for the death of her aunt, who died from positional asphyxiation while in defendant’s care. Plaintiff has alleged that defendant was negligent in four distinct ways: (1) by failing to provide “an accident-free environment” for her aunt; (2) by failing to train its Certified Evaluated Nursing Assistants (CENAs) to recognize and counter the risk of positional asphyxiation posed by bed rails; (3) by failing to take adequate corrective measures after finding Ms. Hunt entangled in her bedding on the day before her asphyxiation; and (4) by failing to inspect plaintiffs bed arrangements to ensure “that the risk of positional asphyxia did not exist for plaintiffs decedent.” We are required in this appeal to determine whether each claim sounds in medical malpractice or ordinary negligence.

Plaintiffs “accident-free environment” claim is one of strict liability; because medical malpractice requires proof of negligence, this claim is not legally cognizable. Moreover, under the standards set forth in Dorris v Detroit Osteopathic Hosp Corp, 460 Mich 26; 594 NW2d 455 (1999), plaintiffs failure-to-train and failure-to-inspect claims sound in medical malpractice. Plaintiffs claim that defendant failed to take action after its employees found Ms. Hunt entangled in her bedding on the day before her asphyxiation, however, sounds in ordinary negligence.

We reverse the judgment of the Court of Appeals and remand this case to the Wayne Circuit Court for proceedings on plaintiffs claim of ordinary negligence and, *415given the equities in this case, on her two medical malpractice claims as well.

I. BACKGROUND

Plaintiffs decedent, Catherine Hunt, was a resident of Oakpointe. She suffered from multi-infarct dementia1 and diabetes, had suffered several strokes, and required twenty-four-hour-a-day care for all her needs, including locomotion, dressing, eating, toileting, and bathing. Hunt’s condition impaired her judgment and reasoning ability and, in turn, caused cerebral atrophy. Hunt had no control over her locomotive skills and was prone to sliding about uncontrollably and, therefore, she was at risk for suffocation by “positional asphyxia.”2

Because Hunt had no control over her locomotive skills, Dr. Donald Dreyfuss, defendant’s medical director, authorized the use of various physical restraints. These included bed rails to keep Hunt from sliding out *416of the bed, as well as a restraining vest that kept her from moving her arms, thereby impeding her ability to slide. The authorized restraints also included wedges or bumper pads that were placed on the outer edge of the mattress to keep her from hurting herself by striking, or entangling herself in, the rails. The use of restraints of this sort is regulated by the state of Michigan to prevent overuse and excessive patient confinement, and must be authorized by a physician.3

Several persons cared for Hunt on a twenty-four-hour basis, including registered nurses, practical nurses, and nursing assistants (CENAs). On March 1, 1997, nursing assistants Monee Olds and Valerie Roundtree noticed that Hunt was lying in her bed very close to the bed rails and was tangled in her restraining vest, gown, and bed sheets. They untangled her from her vest and gown and attempted to position bed wedges onto decedent’s bed to prevent her from slipping into a gap that existed between the mattress and bed rail. The nursing assistants testified that they informed their supervisor that the wedges were not sticking properly and kept falling off, and that better care should be taken in that regard for all patients or else the patients could hurt or even fatally injure themselves.4

*417The next day, March 2, 1997, Hunt slipped between the rails of her bed and was in large part out of the bed with the lower half of her body on the floor but her head and neck under the bed side rail and her neck wedged in the gap between the rail and the mattress, thus preventing her from breathing. When Hunt was extricated, she was transported to a hospital. There was no recovery and, on March 4, 1997, she was taken off life support and died. The cause of her death was listed as positional asphyxia.

Plaintiff filed a suit alleging ordinary negligence against defendant in the Wayne Circuit Court in April 1998. In May 1998, defendant moved for summary disposition pursuant to MCR 2.116(C)(4) and (C)(8), on the basis that plaintiffs claims sounded in medical malpractice rather than ordinary negligence. In August 1998, Judge Pamela Harwood ruled that plaintiffs complaint sounded in ordinary negligence and allowed the case to proceed. In January 1999, Judge Harwood recused herself from the case and it was reassigned to Judge John Murphy.

In June 1999, plaintiff filed a first amended complaint still alleging ordinary negligence. It contained three counts. These were, first, ordinary negligence “by and through” defendant’s employees generally; second, negligent infliction of emotional distress; and third, gross negligence by defendant’s employees generally. Plaintiffs “ordinary negligence” count — the claim at issue in this appeal — contained four distinct claims against defendant:

(a) Negligently and recklessly failing to assure that plaintiffs decedent was provided with an accident-free environment;

(b) Negligently and recklessly failing to train CENAs to assess the risk of positional asphyxia by plaintiffs decedent *418despite having received specific warnings by the United States Food and Drug Administration about the dangers of death caused by positional asphyxia in bed rails;

(c) Negligently and recklessly failing to take steps to protect plaintiffs decedent when she was, in fact, discovered on March 1 entangled between the bed rails and the mattress;

(d) Negligently and recklessly failing to inspect the beds, bed frames and mattresses to assure that the risk of positional asphyxia did not exist for plaintiffs decedent.

In October 1999, defendant again moved for summary disposition on the basis that plaintiffs new claims of ordinary negligence, in fact, sounded in medical malpractice. Unlike Judge Harwood, Judge Murphy, in June 2000, agreed with defendant and ruled that plaintiffs “ordinary negligence” count sounded in medical malpractice.5 In addition, he ruled that, although ordinary negligence claims could be brought against the nursing assistants individually, these claims had not properly been pleaded. The court therefore dismissed the complaint in its entirety without prejudice.

Plaintiff appealed the dismissal to the Court of Appeals. Meanwhile, however, seeking to comply with Judge Murphy’s decision, plaintiff, in August 2000, filed a notice of intent to sue in medical malpractice pursuant to MCL 600.2912b and, in February 2001, refiled her case, filing a second amended complaint alleging medical malpractice. Defendant again brought a motion to dismiss pursuant to 2.116(C)(7), on the basis that the two-year medical malpractice period of limitations had expired. Judge Murphy, in June 2001, disagreed and held that the period of limitations was tolled when Judge Harwood issued her August 1998 decision until that *419decision was reversed by himself in June 2000. Defendant appealed this decision to the Court of Appeals.

The Court of Appeals consolidated plaintiffs appeal from Judge Murphy’s June 2000 decision with defendant’s appeal from his June 2001 decision. The Court of Appeals held in plaintiffs favor, finding that the case sounded in ordinary negligence.6 The Court recognized that, having so held, the issue regarding the tolling of the period of limitations was moot. However, the Court concluded, in dictum, that if plaintiffs claim had sounded in medical malpractice, Scarsella v Pollak, 461 Mich 547; 607 NW2d 711 (2000), would require its dismissal with prejudice. Defendant appealed the Court of Appeals decision that plaintiffs case sounded in ordinary negligence, and we granted leave to appeal in this case and in Lawrence v Battle Creek Health Systems, 468 Mich 944 (2003), ordering that the two cases be argued and submitted together.7

II. STANDARD OF REVIEW

In determining whether the nature of a claim is ordinary negligence or medical malpractice, as well as whether such claim is barred because of the statute of limitations, a court does so under MCR 2.116(C)(7). We review such claims de novo. Fane v Detroit Library Comm, 465 Mich 68, 74; 631 NW2d 678 (2001). In making a decision under MCR 2.116(C)(7), we consider all documentary evidence submitted by the parties, accepting as true the contents of the complaint unless affidavits or other appropriate documents specifically contradict it. Fane, supra; see also MCR 2.116(G)(5)-(6).

*420III. MEDICAL MALPRACTICE VS. ORDINARY NEGLIGENCE

The first issue in any purported medical malpractice case concerns whether it is being brought against someone who, or an entity that, is capable of malpractice. In addressing this issue, defendant argues that, because MCL 600.5838a refers to “the medical malpractice of. . . an employee or agent of a licensed health facility or agency who is engaging in or otherwise assisting in medical care and treatment,” plaintiffs claim sounds in medical malpractice for the simple reason that it alleges negligence committed by an employee of a licensed health care facility who was engaging in medical care and treatment. In response, we point out that MCL 600.5838a(l) is an accrual statute that indicates when a medical malpractice cause of action accrues. Additionally, as we noted in Adkins v Annapolis Hosp, 420 Mich 87, 94-95; 360 NW2d 150 (1984), this statute likewise expands the traditional common-law list of those who are subject to medical malpractice actions.8 However, we caution that, although § 5838a expands the category of who may be *421subject to a medical malpractice action, it does not define what constitutes a medical malpractice action.9 The fact that an employee of a licensed health care facility was engaging in medical care at the time the alleged negligence occurred means that the plaintiffs claim may possibly sound in medical malpractice; it does not mean that the plaintiffs claim certainly sounds in medical malpractice.

*422The second issue concerns whether the alleged claim sounds in medical malpractice. A medical malpractice claim is distinguished by two defining characteristics. First, medical malpractice can occur only “ ‘within the course of a professional relationship.’ ” Dorris, supra at 45 (citation omitted). Second, claims of medical malpractice necessarily “raise questions involving medical judgment.” Id. at 46. Claims of ordinary negligence, by contrast, “raise issues that are within the common knowledge and experience of the [fact-finder].” Id. Therefore, a court must ask two fundamental questions in determining whether a claim sounds in ordinary negligence or medical malpractice: (1) whether the claim pertains to an action that occurred within the course of a professional relationship; and (2) whether the claim raises questions of medical judgment beyond the realm of common knowledge and experience. If both these questions are answered in the affirmative, the action is subject to the procedural and substantive requirements that govern medical malpractice actions.

In considering whether there has been a professional relationship between the plaintiff and the defendant, Dorris is central to our analysis. In that case, this Court held: “ ‘The key to a medical malpractice claim is whether it is alleged that the negligence occurred within the course of a professional relationship.’ ” Id. at 45, quoting Bronson v Sisters of Mercy Health Corp, 175 Mich App 647, 652; 438 NW2d 276 (1989). A professional relationship sufficient to support a claim of medical malpractice exists in those cases in which a licensed health care professional, licensed health care facility, or the agents or employees of a licensed health care facility, were subject to a contractual duty that required that professional, that facility, or the agents or employees of that facility, to render professional health care services to the plaintiff. See Dyer v Trachtman, 470 *423Mich 45; 679 NW2d 311 (2004);10 Delahunt v Finton, 244 Mich 226, 230; 221 NW 168 (1928) (“Malpractice, in its ordinary sense, is the negligent performance by a physician or surgeon of the duties devolved and incumbent upon him on account of his contractual relations with his patient.”);11 see also Hill v Kokosky, 186 Mich App 300, 302-303; 463 NW2d 265 (1990); Oja v Kin, 229 Mich App 184, 187; 581 NW2d 739 (1998).

After ascertaining that the professional relationship test is met, the next step is determining whether the claim raises questions of medical judgment requiring expert testimony or, on the other hand, whether it alleges facts within the realm of a jury’s common knowledge and experience. If the reasonableness of the health care professionals’ action can be evaluated by lay jurors, on the basis of their common knowledge and experience, it is ordinary negligence. If, on the other hand, the reasonableness of the action can be evaluated by a jury only after having been presented the standards of care pertaining to the medical issue before the jury explained by experts, a medical malpractice claim is involved. As we stated in Dorris:

The determination whether a claim will be held to the standards of proof and procedural requirements of a medi *424cal malpractice claim as opposed to an ordinary negligence claim depends on whether the facts allegedly raise issues that are within the common knowledge and experience of the jury or, alternatively, raise questions involving medical judgment. [Dorris, supra at 46, citing Wilson v Stilwill, 411 Mich 587, 611; 309 NW2d 898 (1981).]

Contributing to an understanding of what constitutes a “medical judgment” is Adkins v Annapolis Hosp, 116 Mich App 558; 323 NW2d 482 (1982), in which the Court of Appeals held:

[M]edical malpractice . .. has been defined as the failure of a member of the medical profession, employed to treat a case professionally, to fulfill the duty to exercise that degree of skill, care and diligence exercised by members of the same profession, practicing in the same or similar locality, in light of the present state of medical science. [Citation omitted.]

IV ANALYSIS OF ALLEGATIONS

We now turn to the complaint in the present case.12 Plaintiff alleges that defendant is liable for: (1) negligently failing to assure that plaintiffs decedent was provided with an accident-free environment; (2) negligently failing to inspect the bed, bed frame, and mattress to assure the plaintiffs decedent was not at risk of suffocation; (3) negligently failing to properly train its CENAs regarding the risk to decedent of positional asphyxiation posed by the bed rails; and (4) negligently failing to take steps to protect decedent from further harm or injury after discovering her entangled between her bed rail and mattress on March *4251. We address the application of Dorris to each of these claims below.13

A. PROFESSIONAL relationship

The first question in determining whether these claims sound in ordinary negligence or medical malpractice is whether there was a professional relationship between the allegedly negligent party and the injured party. This analysis is fairly straightforward and, in this case, is identical for each of plaintiffs claims. Because defendant, Oakpointe Villa Nursing Centre, Inc., a licensed health care facility, was under a contractual duty requiring both it and its employees to render professional health care services to plaintiffs decedent, a professional relationship existed to support a claim for medical malpractice.

B. MEDICAL JUDGMENT VS. LAY KNOWLEDGE

The second question is whether the acts of negligence alleged “raise issues that are within the common knowledge and experience of the jury or, alternatively, raise questions involving medical judgment.” Dorris, supra at 46.

1. “ACCIDENT-FREE ENVIRONMENT”

Plaintiffs first claim is that defendant “fail[ed] to assure that plaintiffs decedent was provided with an accident-free environment.” This is an assertion of strict liability that is not cognizable in either ordinary negligence or medical malpractice. With reference to *426ordinary negligence, the test is whether the defendant breached a duty that proximately caused an injury to the plaintiff. See, e.g., Haliw v Sterling Hts, 464 Mich 297, 309-310; 627 NW2d 581 (2001). With reference to medical malpractice law, the Legislature has directed in MCL 600.2912a et seq., that negligence is the standard. Thus, strict liability is inapplicable to either ordinary negligence or medical malpractice. As a result, because this claim is unrecognized in this area of our law, this allegation states no claim at all.

2. FAILURE TO TRAIN

Next, we must determine whether plaintiffs claim that defendant failed to train its staff “to assess the risk of potential asphyxia” is one that requires expert testimony on medical issues. In Dorris at 47, we stated that the plaintiffs allegations “concerning staffing decisions and patient monitoring involve questions of professional medical management and are not issues of ordinary negligence that can be judged by the common knowledge and experience of a jury.” That is not to say, however, that all cases concerning failure to train health care employees in the proper monitoring of patients are claims that sound in medical malpractice. The pertinent question remains whether the alleged facts raise questions of medical judgment or questions that are within the common knowledge and experience of the jury. Id. at 46.

In Dorris, the staff training and patient monitoring issue sounded in medical malpractice because “[t]he ordinary layman does not know the type of supervision or monitoring that is required for psychiatric patients in apsychiatric ward.” Id. at 47 (emphasis added). That is, knowing how to correctly monitor psychiatric patients requires a specialized knowledge of the complex diseases of the mind that may affect psychiatric pa*427tients and how those diseases may influence their behavior, and such knowledge is simply not within the realm of “common knowledge.”

Similarly, in order to assess the risk of positional asphyxiation posed by bed railings, specialized knowledge is generally required, as was notably shown by the deposition testimony of plaintiffs own expert, Dr. Steven Miles. Dr. Miles testified that hospitals may employ a number of different bed rails depending on the needs of a particular patient.14 Accordingly, the assessment of whether a bed rail creates a risk of entrapment for a patient requires knowledge of that patient’s medical history and behavior.15 It is this particularized knowledge, according to Dr. Miles, that should prompt a treating facility to use the bedding arrangement that best suits a patient’s “individualized treatment plan,” and to properly train its employees to recognize any risks inherent in that bedding arrangement and to adequately monitor patients to minimize those risks.

In describing the appropriate arrangement for plaintiffs decedent, Dr. Miles testified:

This patient had a long history of slide and fall-type injuries, and her entire environment should have been adjusted as part of the individualized treatment plan for this.

*428And furthermore, the facility had a general obligation to all of its patients, including Ms. Hunt, to provide beds that did not prevent — present a space that was large enough for an entrapment asphyxiation. And they should have been particularly aggressive in using that type of equipment for Ms. Hunt.

This testimony demonstrates that the ability to assess the risk of positional asphyxia and, thus, the training of employees to properly assess that risk, involves the exercise of professional judgment. The picture necessarily gets more complicated when one considers additional restraint mechanisms used in tandem with bed railing such as vests or pelvic restraints to promote the safety of patients.

Indeed, an article in the Journal of the American Geriatrics Society coauthored by plaintiffs expert, Dr. Miles, stresses the need for “clinical and ergonomic changes” in the use of bed rails and decries the widespread use of bed railings “without... a clear sense of their role in a treatment plan and without regulatory attention to their design.”16 This article concludes with a call for nursing homes to limit the use of bedrails, but notes that research into the relative costs and benefits of using bedrails is “needed urgently.”17

This much is clear: in order to determine whether defendant adequately trained its CENAs to recognize the risks posed by particular configurations of bed rails and other prescribed restraint systems, therefore, the fact-finder will generally require expert testimony on what specialists in the use of these systems currently know about their risks and on how much of this knowledge defendant ought to have conveyed to its staff.

*429Given the patent need in this case for expert testimony regarding plaintiffs claim of failure to train, we conclude that this claim sounds in medical malpractice under Dorris.

3. FAILURE TO INSPECT

Next, plaintiff alleges that defendant is liable for “[n]egligently and recklessly failing to inspect the beds, bed frames and mattress to assure that the risk of positional asphyxia did not exist for plaintiffs decedent.” It is clear from the record in this case that plaintiffs “failure to inspect” claim is not that defendant and its agents actually failed to check Ms. Hunt’s bedding arrangements,18 but that defendant failed to recognize that her bedding arrangements posed a risk of asphyxiation.

As shown above, and as demonstrated through the deposition testimony of plaintiffs expert, the risk of asphyxiation posed by a bedding arrangement varies from patient to patient. The restraining mechanisms appropriate for a given patient depend upon that patient’s medical history. Thus, restraints such as bed railings are, in the terminology of plaintiffs expert physician, part of a patient’s “individualized treatment plan.”

The risk assessment at issue in this claim, in our judgment, is beyond the ken of common knowledge, because such an assessment require understanding and consideration of the risks and benefits of using and maintaining a particular set of restraints in light of a patient’s medical history and treatment goals. In order *430to determine then whether defendant has been negligent in assessing the risk posed by Hunt’s bedding arrangement, the fact-finder must rely on expert testimony. This claim, like the claim described above, sounds in medical malpractice.

4. FAILURE TO TAKE STEPS

We turn, finally, to a claim fundamentally unlike those discussed previously. Plaintiff alleges that defendant “[negligently and recklessly fail[ed] to take steps to protect plaintiffs decedent when she was, in fact, discovered on March 1 [1997] entangled between the bed rails and the mattress.”

This claim refers to an incident on March 1, 1997— the day before Ms. Hunt was asphyxiated — when two of defendant’s CENAs found Ms. Hunt tangled in her bedding and dangerously close to asphyxiating herself in the bed rails. According to the CENAs, they moved Ms. Hunt away from the rail and informed their supervising nurses that Ms. Hunt was at risk of asphyxiation.

Plaintiff now contends, therefore, that defendant had notice of the risk of asphyxiation through the knowledge of its agents and, despite this knowledge of the problem, defendant did nothing to rectify it. It bears repeating that plaintiffs allegation in this claim is not that defendant took inappropriate steps in dealing with the patient’s compulsive sliding problem or that defendant’s agents were negligent in creating the hazard in the first place. Instead, plaintiff claims that defendant knew of the hazard that led to her death and did nothing about it.

This claim sounds in ordinary negligence. No expert testimony is necessary to determine whether defendant’s employees should have taken some sort of cor*431rective action to prevent future harm after learning of the hazard. The fact-finder can rely on common knowledge and experience in determining whether defendant ought to have made an attempt to reduce a known risk of imminent harm to one of its charges.

Suppose, for example, that two CENAs employed by defendant discovered that a resident had slid underwater while taking a bath. Realizing that the resident might drown, the CENAs lift him above the water. They recognize that the resident’s medical condition is such that he is likely to slide underwater again and, accordingly, they notify a supervising nurse of the problem. The nurse, then, does nothing at all to rectify the problem, and the resident drowns while taking a bath the next day.

If a party alleges in a lawsuit that the nursing home was negligent in allowing the decedent to take a bath under conditions known to be hazardous, the Dorris standard would dictate that the claim sounds in ordinary negligence. No expert testimony is necessary to show that the defendant acted negligently by failing to take any corrective action after learning of the problem. A fact-finder relying only on common knowledge and experience can readily determine whether the defendant’s response was sufficient.

Similarly, no expert testimony is required here in order to determine whether defendant was negligent in failing to respond after its agents noticed that Ms. Hunt was at risk of asphyxiation. Professional judgment might be implicated if plaintiff alleged that defendant responded inadequately, but, given the substance of plaintiffs allegation in this case, the fact-finder need only determine whether any corrective action to reduce the risk of recurrence was taken after defendant’s agents noticed that Ms. Hunt was in peril. Thus, *432plaintiff has stated a claim of ordinary negligence under the standards articulated in Dorris.

V STATUTE OF LIMITATIONS

Having decided that two of plaintiffs claims sound in medical malpractice, we must determine whether plaintiffs medical malpractice claims are now time-barred. See MCR 2.116(C)(7).

The period of limitations for a medical malpractice action is ordinarily two years. MCL 600.5805(6). According to MCL 600.5852, plaintiff had two years from the date she was issued letters of authority as personal representative of Hunt’s estate to file a medical malpractice complaint. Because the letters of authority were issued to plaintiff on January 20, 1998, the medical malpractice action had to be filed by January 20, 2000. Thus, under ordinary circumstances, plaintiffs February 7, 2001, medical malpractice complaint (her third complaint in total) would be time-barred.

The equities of this case, however, compel a different result. The distinction between actions sounding in medical malpractice and those sounding in ordinary negligence is one that has troubled the bench and bar in Michigan, even in the wake of our opinion in Dorris. Plaintiffs failure to comply with the applicable statute of limitations is the product of an understandable confusion about the legal nature of her claim, rather than a negligent failure to preserve her rights. Accordingly, for this case and others now pending that involve similar procedural circumstances, we conclude that plaintiffs medical malpractice claims may proceed to trial along with plaintiffs ordinary negligence claim. MCR 7.316(A)(7). However, in future cases of this nature, in which the line between ordinary negligence and medical malpractice is not easily distinguishable, plaintiffs are *433advised as a matter of prudence to file their claims alternatively in medical malpractice and ordinary negligence within the applicable period of limitations.19

VI. CONCLUSION

Plaintiff has stated two claims that require expert testimony and therefore sound in medical malpractice. Although these claims were filed after the applicable period of limitations had run and would ordinarily be time-barred, the procedural features of this case dictate that plaintiff should be permitted to proceed with her medical malpractice claims. The claim that defendant negligently failed to respond after learning that Ms. Hunt’s bedding arrangements created a risk of asphyxiation sounds in ordinary negligence. Finally, plaintiffs claim regarding an “accident-free environment” sounds in strict liability and is not cognizable. Accordingly, we reverse the judgment of the Court of Appeals and remand this case to the circuit court for further proceedings consistent with this opinion.

(dissenting). The question in this case is whether plaintiffs claims sound in medical malpractice or ordinary negligence. I disagree with the majority’s reading of plaintiffs complaint and believe that all of plaintiffs claims sound in ordinary negligence. I also disagree with the majority’s analysis of the statute of limitations issue.

*434BACKGROUND

Plaintiff’s decedent was a resident of defendant’s nursing care facility. Among her needs were safety restraints on her bed to prevent her from falling out and injuring herself. In early 1997, defendant’s nurses’ assistants noted that she had developed a propensity to move around in bed. Because of her petite stature and the configuration of the bed, she was in danger of slipping under the bedrails and catching her neck. This could lead to strangulation and death.

Shortly after, the assistants’ fears were realized. First, they discovered plaintiffs decedent “tangled up in the rails,” her clothes, and the bedding. They successfully extricated her, but feared that she was in grave danger of being hanged. Yet, no change was made in the restraint configuration. The next day, she was discovered caught by her neck under the rails. This time, she did not recover. She died two days later after being removed from life support.

Plaintiff brought suit against the facility. Following pretrial motions for summary disposition, plaintiff was allowed to file a first amended complaint in June 1999. She alleged three counts of negligence: ordinary negligence, negligent infliction of emotional distress, and gross negligence.1 Ante at 417. Central to the resolution of this case is plaintiffs count for ordinary negligence.

The ordinary negligence count consisted of four distinct claims. The first was that defendant, by providing medical care and housing to plaintiffs decedent, *435owed her decedent a duty to provide an accident-free environment. Defendant had a duty, plaintiff asserted, to assure that plaintiffs decedent was not subjected to an unreasonable risk of injury.

Second, plaintiff asserted that defendant breached its duty to train its staff to recognize the danger posed by bedrails. According to plaintiffs complaint, defendant had received specific information about this danger from the United States Food and Drug Administration (FDA). The allegation is that defendant failed to take precautions or share this information with its staff.

Third, plaintiff asserted that defendant discovered plaintiffs decedent caught between the rails and mattress. Plaintiff complains that defendant failed to prevent a recurrence by not remedying the rails-mattress configuration.

Fourth, plaintiff asserted that defendant had failed to inspect the bed’s configuration to ensure that a danger of strangulation was not present.

Defendant moved for summary disposition under MCR 2.116(C)(7), and the circuit court granted the motion. It determined that plaintiffs ordinary negligence claims were really allegations of medical malpractice.

Plaintiff appealed to the Court of Appeals. She also took measures to preserve her claims as malpractice claims by filing an amended complaint and a notice of intent to sue pursuant to MCL 600.2912b. Defendant moved to dismiss, asserting that the suit was time-barred under the medical malpractice statutory period of limitations. MCL 600.5805(6). When the circuit court held that the statutory period had been tolled, defendant went to the Court of Appeals.

*436The Court of Appeals consolidated both parties’ appeals. It concluded that plaintiffs claims sounded in ordinary negligence, adding that they would be barred by the limitations period if they sounded in medical malpractice. Unpublished opinion per curiam, issued May 21, 2002 (Docket Nos. 228972, 234992). We granted defendant’s subsequent application for leave to appeal.2 468 Mich 943 (2003).

The majority determines that only one of plaintiffs claims sounds in ordinary negligence, that another is not cognizable under Michigan law, and that the other two are medical malpractice claims. It bases its holding on two facts: One, defendant did not respond at all upon finding plaintiffs decedent entangled in her bedding and, therefore, one of plaintiffs claims is for ordinary negligence. Two, the use of bedrails must be prescribed by a medical professional and, therefore, the remaining claims necessarily sound in medical malpractice.

STANDARD OF REVIEW

We review motions for summary disposition under MCR 2.116(C)(7) de novo. We accept the allegations in the complaint and documentary evidence as true unless other documents specifically contradict them. Fane v Detroit Library Comm, 465 Mich 68, 74; 631 NW2d 678 (2001).

MEDICAL MALPRACTICE VERSUS ORDINARY NEGLIGENCE

In Adkins v Annapolis Hosp,3 we recognized that ordinary negligence could occur in the course of medical *437care. In this case, plaintiff is alleging that ordinary negligence occurred. She does not dispute that a professional medical relationship existed between defendant and her decedent. But she relies on the established fact that every medical professional remains under a duty to exercise reasonable care. Also, professional standards of medical care supplement but do not necessarily supplant the ordinary duty of care.

Various differences exist between medical malpractice and negligence. When medical malpractice occurs, there has been a failure or omission that cannot be assessed by a layperson; it involves a matter that requires the exercise of professional medical judgment. Without expert testimony, the ordinary juror cannot determine if a defendant medical professional has fulfilled its duty of professional care. Dorris v Detroit Osteopathic Hosp Corp, 460 Mich 26, 47; 594 NW2d 455 (1999). By contrast, expert witnesses are not always required in ordinary negligence actions because the trier of fact can often rely on its own common knowledge and experience. In addition, medical malpractice actions involve the alleged breach of medical standards of care; negligence actions do not.

THE NEGLIGENCE ALLEGED

Here, plaintiffs amended complaint alleged that defendant was negligent in four ways. Defendant is alleged to have breached its duties to

(a) ... assure that plaintiffs decedent was provided with an accident-free environment;

(b) • • • train [nurses’ assistants] to assess the risk of positional asphyxia by plaintiffs decedent despite having received specific warnings ... ;

*438(c) ... take steps to protect plaintiffs decedent when she was, in fact, discovered on March 1 [1997] entangled between the bed rails and the mattress;

(d) .. . inspect the beds, bed frames and mattresses to assure that the risk of positional asphyxia did not exist for plaintiffs decedent.

With respect to the first claim, I disagree with the majority that plaintiffs assertion of a duty to provide an accident-free environment is not cognizable under Michigan law. Ante at 425-426. We have consistently held that the nature of the claim alleged is based on the underlying facts. It is independent of the words used to describe it. See Dorris at 43.

Plaintiffs decedent was in defendant’s custodial care. As the Court of Appeals stated, defendant was obligated to take reasonable precautions to provide a reasonably safe environment. Unpublished opinion per curiam, issued May 21, 2002 (Docket Nos. 228972, 234992), citing Owens v Manor Health Care Corp, 159 Ill App 3d 684, 688; 512 NE2d 820 (1987). A breach of this duty can support a claim for ordinary negligence. Plaintiffs first claim should be read to mean that defendant was obligated to provide an environment free of negligently caused accidents.

Contrary to the majority’s reading of this claim, plaintiff has not asserted that defendant was the guarantor of the safety of plaintiffs decedent. The ordinary juror can assess whether defendant’s alleged actions or inactions constituted reasonable measures to fulfill its duty.

The second claim is that defendant breached its duty to train its nurses’ assistants. I agree with the majority that assessing the medical needs of patients requires medical expertise. Similarly, assessing whether those needs were adequately addressed requires medical ex*439pertise. See part IV(B)(2), ante at 426-429. However, a fair reading of this claim reveals that plaintiff is not challenging defendant’s assessment of her decedent’s medical needs. Moreover, plaintiff is not challenging whether bed rails and other restraints were appropriately prescribed.

Instead, plaintiff asserts that defendant knew of the dangers posed by bed rails, yet, it took no steps to pass this information along to its employees. As the majority opines,

[n]o expert testimony is necessary to determine whether [defendant] should have taken some sort of corrective action to prevent future harm after learning of the hazard. The fact-finder can rely on common knowledge and experience in determining whether defendant ought to have made an attempt to reduce a known risk of imminent harm to one of its charges.[4]

“Some sort of corrective action” may include, as plaintiff alleges, training employees or passing along specific information to them that it has learned from other employees or the FDA. Plaintiff asserts that defendant failed to act once it had knowledge of a hazard, not that it breached a medical standard of care. Hence, this claim sounds in ordinary negligence as well.

Plaintiffs third and fourth claims concern defendant’s actions with respect to her decedent becoming entangled in the bedding. Plaintiff alleged that defendant failed to “take steps to protect plaintiffs decedent when she was, in fact, discovered on March 1 [1997] entangled between the bed rails and the mattress” and to “inspect the beds, bed frames and mattresses to assure that the risk of positional asphyxia did not exist for plaintiffs decedent.”

*440Plaintiff asserts that the nurses’ assistants employed by defendant failed to notify their supervisors when plaintiffs decedent was found caught in the bedrails on the first occasion. Alternatively, plaintiff asserts that a warning was given to the supervisors that they disregarded.

Again, plaintiff states: they “ [negligently and recklessly fail[ed] to inspect the beds, bed frames and mattresses to assure that the risk of positional asphyxia did not exist...” and “to take steps to protect plaintiffs decedent....” These allegations assert the breach of a duty of due care owed by defendant to plaintiffs decedent that can be evaluated by ordinary jurors.

Defendant’s nurses’ assistants were alerted to the danger when two of them first found plaintiffs decedent trapped in the bedrails. One specifically testified that, although she did not comprehend the medical needs of plaintiffs decedent, she recognized that the decedent was in serious physical danger. She expressed to her supervisor her fear that the elderly woman would be found dead if something were not done.

Plaintiff has presented evidence that defendant’s nurses’ assistants did not require medical training to understand that this small, frail person could again slip under the bedrail and jam her neck, endangering her life. Medical training was not needed to instruct them that the bedrail-mattress configuration had to be changed.

Laypersons can properly assess whether the manner in which bedrails and mattresses are configured creates an unreasonable risk of harm to a person like plaintiffs decedent. The claims do not involve the breach of a medical standard of care. They involve simple neglect to act or ordinary negligence, as the majority concedes.

*441Unlike the majority, I do not place undue emphasis on the fact that the nurses’ assistants had previously discovered plaintiffs decedent in a dangerous position. Ante at 431-432. Any person caring for her could have recognized the danger that the bedding posed to a petite, frail, and elderly person who lacked normal control over her movements.5

The danger here was similar to that experienced by an infant in a crib whose mattress is too small and whose rails allow the baby to slip through. Those caring for such a child would quickly recognize the danger, and an expert would not be required to point it out. Similarly, ordinary jurors can assess whether defendant’s caregivers here should have recognized the danger and acted with due care.

As stated earlier in this opinion, the nature of the claim is independent of the words used to describe it. Plaintiff used the proper term “positional asphyxia” to describe being hanged. However, use of the medical term does not transform plaintiffs negligence claim into one sounding in malpractice.

Defendant’s supposition that ordinary people are incapable of recognizing an obvious danger of hanging is untenable, particularly here where untrained people actually did recognize the danger. The assessment of a hazard does not require professional training merely because a professional is capable of assessing it as well and can explain the exact mechanism of the danger. If that were true, a physical science expert would be required in this case as well as a medical one. That *442expert would be needed to inform the jury how plaintiffs decedent was in danger of strangulation because gravity would pull her down once she slipped beneath the bedrails.

STATUTE OF LIMITATIONS

Generally the period of limitations is tolled at the time the complaint is filed. MCL 600.5856(a). The period for an action premised on ordinary negligence is three years. MCL 600.5805(10); Stephens v Dixon, 449 Mich 531; 536 NW2d 755 (1995). Plaintiffs decedent died in March 1997, and plaintiff brought her action in April 1998. This was well within the period of limitations applicable to ordinary negligence actions, as well as wrongful death actions premised on medical malpractice. MCL 600.5852; MCL 600.5805(6). Still well within the applicable period of limitations, the trial court initially ruled that plaintiffs claim sounded in ordinary negligence. Thus, under MCL 600.5856(a), the period of limitations was tolled.

I believe that plaintiff and other similarly situated litigants are entitled to rely on a trial court’s decision that their case sounds in ordinary negligence. The filing of plaintiffs ordinary negligence complaint tolled the period of limitations, at least until the new trial judge reversed that decision.

“Plaintiffs failure to comply with the applicable statute of limitations” was less the “product of [her] understandable confusion about the legal nature of her claim . . .”6 and more the product of plaintiffs justifiable reliance on the trial court’s initial ruling.

This Court need not resort to equity to save plaintiffs so-called medical malpractice claims. MCL 600.5856(a) *443and the initial trial court decision dictated that plaintiffs filing of the ordinary negligence complaint tolled the running of the period of limitations.

Finally, the majority’s “prudent” decision that obliges someone injured by a negligent medical practitioner to allege alternate theories of medical malpractice and ordinary negligence pertaining to a single injury is ill-conceived. It needlessly complicates and impedes the injured person’s efforts to recover through the courts from those responsible for his plight. The majority’s free and unsolicited advice sends the wrong message to the bench and bar, and places an undue burden on injured people.

CONCLUSION

In this case, plaintiff has alleged that defendant had notice of a risk of harm that was readily apparent to the layperson and could have been rectified by a layperson. She has also alleged that, after receiving notice of the danger, defendant negligently missed several opportunities to avert it.

Medical expertise is not required to determine whether defendant’s nonresponses constituted a failure to take ordinary care. An expert could render an opinion on the issues in this case, but it is unnecessary because the case does not raise questions of medical judgment. It does not involve the breach of medical standards of care. Instead, the issues are within the common knowledge and experience of lay jurors. Hence, plaintiff should be enabled to proceed under a theory of ordinary negligence.

Moreover, if any of plaintiffs claims did sound in medical malpractice, more than the equities of this case require that plaintiff be allowed to proceed; plaintiff *444reasonably relied on the decisions of the lower courts that all her claims sound in ordinary negligence.

The decision of the Court of Appeals should be affirmed to the extent that it found that all of plaintiffs claims sound in negligence.
