A nurse is preparing to administer disulfiram 375 mg PO once daily. Available is disulfiram 250 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

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.

A. Keeping staff interactions to a minimum may not be beneficial as the client might require regular monitoring and interaction to assess their condition and needs.
B. When a client is restrained, it's crucial to prevent complications such as muscle stiffness and joint contractures. Range-of-motion exercises help maintain circulation, prevent discomfort, and preserve joint mobility. However, this is not the most important action.
C. Restraints should only be used when absolutely necessary and prescribed by a provider. In many jurisdictions and healthcare facilities, the use of restraints requires a specific order that must be renewed periodically (often every 24 hours). This practice ensures that the need for restraints is continually reassessed and that they are not used longer than necessary.
D. Accurate and frequent documentation is essential when a client is restrained. Documentation should include the client's behavior, physical assessments, interventions provided (such as medication administration or hygiene care), and responses to interventions. However, this is not the most important action.
