A nurse in a mental health clinic is collecting data from a client to determine the client's risk for suicide. Which of the following findings should the nurse identify as a risk factor for suicide? (Select all that apply.)

A. Lanugo refers to fine, soft hair that grows on the face, back, and arms as a result of malnutrition. It is more common in anorexia nervosa rather than bulimia nervosa.
B. Muscle wasting is not typically a primary symptom of bulimia.
C. Hypomagnesemia, or low magnesium levels, may occur but is not very characteristic of bulimia nervosa.
D. Hypokalemia, or low levels of potassium in the blood, is a common finding in individuals with bulimia nervosa who engage in purging behaviors such as vomiting or misuse of diuretics. Potassium is crucial for proper muscle and nerve function, and low levels can lead to symptoms such as muscle weakness, fatigue, cardiac arrhythmias, and in severe cases, paralysis.

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.
