¶1 — When a caretaker uses a vulnerable adult’s property to further the caretaker’s own goal, even if self-destructive, such use constitutes “financial exploitation” as defined by former RCW 74.34.020(6) (2010). The Department of Social and Health Services (Department) did not err in concluding that Estera Gradinaru financially exploited a vulnerable adult when she used that adult’s morphine in a failed suicide attempt. We affirm.

FACTS

¶2 In October 2010, Gradinaru was the co-owner of an adult family home in Bellevue. Elaine, one of the residents of the home, was in hospice care and had been prescribed “comfort medications,” including liquid morphine, for end of life treatment.1

¶3 On October 12, Gradinaru was emotionally distressed and in physical pain. She took Elaine’s morphine with her to a park and ride and ingested one-half capful of the morphine, which made her feel sleepy. Her father arrived at the park and ride, and Gradinaru was taken to Overlake Hospital. She was admitted to the psychiatric unit after she told the treating staff that she ingested the morphine in a failed suicide attempt.

¶4 The Department investigated and made a preliminary finding that Gradinaru financially exploited a vulnerable adult. On appeal, an administrative law judge issued an initial order reversing the Department’s finding. The Department petitioned the Board of Appeals (Board) to review the initial order. In its review decision and final order, the Board concluded that Gradinaru financially exploited a vulnerable adult. Gradinaru appealed to King County Superior Court, which affirmed the Board’s review decision and final order.

¶5 Gradinaru appeals.

*21 DISCUSSION

¶6 Gradinaru argues that her failed suicide attempt was not “financial exploitation” of a vulnerable adult as that term is defined in former RCW 74.34.020(6).2 We disagree.

¶7 The Administrative Procedure Act governs our review of the Board’s decision.3 “The burden of demonstrating the invalidity of agency action is on the party asserting invalidity.”4 We will reverse if the Board “erroneously interpreted or applied the law.”5 The interpretation of “financial exploitation” raises a question of law and is reviewed de novo under the error of law standard.6

¶8 The abuse of vulnerable adults act (Act) was enacted to protect vulnerable adults who “may be subjected to abuse, neglect, financial exploitation, or abandonment by a family member, care provider, or other person who has a *22relationship with the vulnerable adult.”7 Former RCW 74.34.020(6) defines “financial exploitation” as “the illegal or improper use of the property, income, resources, or trust funds of the vulnerable adult by any person for any person’s profit or advantage other than for the vulnerable adult’s profit or advantage.” A finding of financial exploitation prohibits an individual from being employed in a capacity that would allow him or her to have unsupervised access to vulnerable adults.8

¶9 Gradinaru contends that her use of the morphine did not constitute an “advantage” to her because attempting suicide is not medically beneficial.

¶10 The term “advantage” is not defined in the Act. Undefined words in a statute are accorded their ordinary meanings.9 The dictionary defines “advantage” as “a more favorable or improved position or condition [;] . . . benefit, profit, or gain of any kind.”10 In the context of this statute, a person engaging in the unauthorized use of a vulnerable adult’s property receives an advantage when that use benefits or facilitates the goals of the person using the property, whether or not that goal is wise or healthy.

¶11 Any attempt at suicide is troubling, but the question presented here is whether the use of Elaine’s property benefited Gradinaru by allowing her to further her goal, even if self-destructive, and thus was a use prohibited under the statute. Gradinaru’s goals were advanced by gaining access to Elaine’s morphine. Gradinaru did not have to spend her own money or time finding some other source of morphine. And it is undisputed that Gradinaru’s use of Elaine’s morphine did not profit or advantage Elaine.

*23¶12 Gradinaru argues that it is not reasonable to construe an attempt to commit suicide as an act taken for the benefit or gain of the actor because it results in medical harm. But nothing in the statute requires the court or the Department to consider whether the illegal or improper use of the victim’s medication was helpful or harmful to the individual who used the medication. The focus of the statute is to protect vulnerable adults. Allowing an exception for using a vulnerable adult’s property in a way that is harmful would lead to an absurd result.11 For example, if a drug addict steals a vulnerable adult’s medication for his own illicit use, he should not evade a finding of financial exploitation because his drug use is medically harmful to him.12

¶13 Gradinaru argues that the Board’s interpretation leads to absurd results. Specifically, she contends that under the Board’s interpretation, any person who attempts to commit suicide using property stolen from a vulnerable adult (a gun, a rope, etc.) will be liable for financial exploitation. But this result is consistent with the purpose of the statute: to protect a vulnerable adult who is unable to protect herself by penalizing an individual who improperly or illegally uses that vulnerable adult’s property for her own purpose in a way that does not benefit the vulnerable adult.

¶14 Next, Gradinaru argues that the Board’s interpretation of the statute is improper because it does not require a “financial” benefit to the user, as implicitly required by the term “financial exploitation.” Gradinaru argues that “finan*24cial” extends only to a vulnerable adult’s “liquid” resources.13 But her argument ignores that “financial exploitation” is defined by the statute to expressly include the use of “property, income, resources, or trust funds.” It is not limited to liquid assets. In this case, the morphine was Elaine’s property. Whether Gradinaru chose to sell or use that property, it was to her own advantage rather than Elaine’s advantage and constituted financial exploitation.

¶15 Finally, Gradinaru argues that the examples of “financial exploitation” provided in the statute support her argument that only use of “financial assets” is prohibited.14 We note that the nonexclusive list of examples were not part of the statute when the Department determined that Gradinaru committed financial exploitation.15 Even so, the examples include the use of a vulnerable adult’s “property, income, resources, or trust funds” and are not limited to “financial assets.”16 Therefore, the recently added examples do not support a different result.

¶16 Financial exploitation extends to the illegal or improper use of a vulnerable adult’s property to further a goal of the person who took that property. The Department did not err in concluding that Gradinaru’s illegal taking and use of a patient’s morphine was an act of “financial exploitation” as defined by the statute. We affirm.
