Correct Answer: B

Rationale: Engaging the patient in a reality-based activity is the most appropriate intervention for a patient with schizophrenia experiencing hallucinations. This intervention can help distract the patient from the hallucinations and reorient them to the present, promoting a connection with reality and potentially reducing distress associated with the hallucinations. Choice A, encouraging the patient to ignore the voices, may not be effective as it can be challenging for the patient to dismiss the hallucinations. Choice C, providing a quiet environment, is helpful but may not directly address the hallucinations. Choice D, asking the patient to describe the hallucinations in detail, may increase the patient's focus on the hallucinations, potentially worsening distress.

Correct Answer: B

Rationale: During a manic episode, individuals may experience heightened energy levels and reduced impulse control. Providing a structured environment with limited stimuli is the most appropriate nursing intervention. This approach helps reduce excessive stimulation and potential triggers for further escalation of manic behavior. It promotes a calming and controlled setting, assisting in managing symptoms and promoting the patient's well-being. Encouraging group activities (Choice A) may lead to overstimulation, allowing the patient to engage in physical activities freely (Choice C) could be risky due to impulsivity, and giving detailed tasks (Choice D) might overwhelm the individual.

Correct Answer: B

Rationale: When a patient is prescribed risperidone, an atypical antipsychotic, the nurse should monitor for weight gain as it is a common side effect of this medication. Weight gain can occur due to metabolic changes and increased appetite associated with risperidone use. Agranulocytosis is a severe decrease in a type of white blood cells, and it is not a common side effect of risperidone. Hair loss and hyperthyroidism are also not typically associated with risperidone use.

Correct Answer: B

Rationale: The correct answer is B: Insomnia. Escitalopram, a selective serotonin reuptake inhibitor (SSRI), commonly causes insomnia as a side effect. Patients should be informed about the possibility of experiencing difficulty falling or staying asleep when starting this medication. Choices A, C, and D are incorrect because weight gain, diarrhea, and hypertension are not typically associated with escitalopram use.

Correct Answer: B

Rationale: Anhedonia, the inability to feel pleasure in activities that were once enjoyable, is a hallmark symptom of major depressive disorder. Patients with major depressive disorder often experience a pervasive feeling of emptiness and loss of interest in activities they used to find pleasurable. Euphoria, increased energy, and racing thoughts are more commonly associated with conditions like bipolar disorder rather than major depressive disorder.
