A nurse at a mental health clinic is caring for four clients. The nurse should recognize that which of the following clients is using dissociation as a defense mechanism?

Implement fall precautions for the client.

• A. Implement fall precautions for the client. This is correct because risperidone can cause orthostatic hypotension, which can increase the risk of falls and injuries. The nurse should advise the client to change positions slowly, avoid alcohol and dehydration, and use assistive devices as needed.
• B. Monitor the client's thyroid function. This is incorrect because risperidone does not affect thyroid function. The nurse should monitor the client's thyroid function if they are taking lithium, which can cause hypothyroidism.
• C. Place the client on a fluid restriction. This is incorrect because risperidone does not cause fluid retention or overload. The nurse should encourage adequate fluid intake and monitor the client's fluid balance.
• D. Discontinue the medication if hallucinations occur. This is incorrect because hallucinations are a symptom of schizophrenia, not a side effect of risperidone. The nurse should not discontinue the medication abruptly, as this can cause withdrawal symptoms and relapse of psychosis. The nurse should assess the client's response to the medication, report any adverse effects, and adjust the dosage as prescribed.

- A. This choice is incorrect because an older adult client who reports constipation of 4 days is not an urgent situation that requires immediate attention. The nurse should assess the client's hydration status, bowel habits, and medication use, and provide education on dietary and lifestyle modifications to prevent constipation.

- B. This choice is incorrect because a preschooler who has a skin rash is not an urgent situation that requires immediate attention. The nurse should assess the type, location, and distribution of the rash, as well as any history of allergies, exposure, or infection, and provide appropriate treatment and education.

- C. This choice is incorrect because an adolescent who has a closed fracture is not an urgent situation that requires immediate attention. The nurse should assess the site of injury, neurovascular status, pain level, and immobilization device, and provide analgesia and education on fracture care.

- D. This choice is correct because a middle adult client who has unstable vital signs is an urgent situation that requires immediate attention. The nurse should assess the client's level of consciousness, airway, breathing, circulation, and possible causes of instability, and initiate lifesaving interventions.
