A nurse is collecting data from a client who is experiencing opioid withdrawal. Which of the following manifestations should the nurse expect?

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.

A. Lanugo refers to fine, soft hair that can develop on the face, back, and other parts of the body in response to malnutrition and low body fat. It is a compensatory mechanism to help regulate body temperature in individuals with severe weight loss, including those with anorexia nervosa. Therefore, the nurse should expect to find lanugo in a client with anorexia nervosa.
B. Cold extremities are a common finding in individuals with anorexia nervosa due to reduced body fat and poor circulation. The body's natural response to conserve heat is impaired when body fat is extremely low. Therefore, cold extremities are expected in clients with anorexia nervosa.
C. Hypotension, or low blood pressure, can occur in individuals with anorexia nervosa due to dehydration, electrolyte imbalances (such as low potassium levels), and reduced cardiac output. These conditions are often associated with severe malnutrition and can lead to cardiovascular complications. Therefore, hypotension is a potential finding in clients with anorexia nervosa.
D. Tooth erosion can result from frequent vomiting, which is a behavior sometimes seen in individuals with anorexia nervosa, particularly those with purging subtype (anorexia nervosa binge-eating/purging type). Stomach acid from vomiting can damage tooth enamel over time, leading to tooth erosion. Therefore, the nurse should expect to find tooth erosion in clients who engage in purging behaviors.
E. Diarrhea is less commonly associated with anorexia nervosa. Individuals with anorexia nervosa typically have reduced food intake, which can lead to constipation rather than diarrhea. However, in some cases, diarrhea can occur due to malnutrition-related changes in bowel function. It is not a consistent finding but can occasionally be observed.
