A nurse is collecting data from a client who has bulimia nervosa. Which of the following findings should the nurse expect?

A. The PSDA applies to all adult clients regardless of age. It ensures that adults have the right to make decisions about their medical care, including the right to accept or refuse treatment, regardless of whether they are elderly or not. Age is not a factor in the applicability of the PSDA.
B. While it's common for a living will to be witnessed, it is not a legal requirement under the PSDA.
C. Advance directives are applicable to all clients, including those receiving mental health care.
D. The Patient Self-Determination Act (PSDA) ensures that adult patients are informed about their rights to make decisions regarding their medical care, including the right to accept or refuse treatment and to prepare an advance directive.

A. Cognitive behavioral therapy (CBT) is a commonly used psychotherapy approach for bipolar disorder. Attending a CBT class typically does not require specific informed consent beyond the general consent for treatment, as it involves non-invasive, non-experimental therapeutic techniques aimed at improving coping skills and managing symptoms. In most cases, attending therapy sessions like CBT is considered part of routine care for mental health conditions.
B. Experimental medications involve drugs or treatments that are not yet approved by regulatory agencies (such as the FDA in the United States) for general use. For a client to participate in a clinical trial or receive an experimental medication, they must provide explicit informed consent after being informed about the potential risks, benefits, and uncertainties associated with the treatment. This process ensures that the client understands they are participating in research and not receiving standard care.
C. Participating in a group exercise program is generally considered a routine therapeutic intervention aimed at promoting physical health and well-being. While informed consent is important for all interventions, including exercise programs, it typically involves providing general information about the program's goals, activities, and any potential risks. Clients are not consenting to experimental treatments or procedures that go beyond standard exercise protocols.

D. Light therapy, also known as phototherapy, is a treatment often used for seasonal affective disorder (SAD) and other mood disorders. It involves exposure to specific wavelengths of light to regulate circadian rhythms and improve mood. While light therapy is a specialized treatment, it is a standard intervention for mood disorders and does not typically require separate informed consent beyond what is provided for standard medical treatments.
