Correct Answer: A

Rationale: The correct answer is A: Attempting to physically restrain the client. Physical restraint should only be performed by trained professionals in a safe manner to prevent harm to the client and staff. In this scenario, the mental health worker should not attempt physical restraint, as it can escalate the situation and potentially lead to harm. Choices B, C, and D do not pose an immediate risk and can be part of de-escalation strategies. Choice B suggests guiding the client to a quiet area, choice C involves using a loud voice for better communication, and choice D indicates maintaining a safe distance, which are appropriate interventions to manage escalating aggressive behavior.

Correct Answer: A

Rationale: A positive response to treatment for a client with an eating disorder is indicated by adherence to the treatment plan and an increase in self-care activities. These behaviors show that the client is actively engaging in their treatment and taking steps towards recovery. Option B, increased isolation from others, is not indicative of a positive response to treatment as it may suggest withdrawal or avoidance. Option C, frequent complaining about treatment procedures, is not a behavior that signifies a positive response; it may indicate dissatisfaction or discomfort with the treatment. Option D, refusal to eat meals provided by the unit, is also not a positive response as it could suggest continued resistance to treatment and potential worsening of symptoms.

Correct Answer: A

Rationale: The best indicator of improvement in a client with depression is initiating interactions with others. This behavior demonstrates that the client is becoming less withdrawn and more self-directed, showing an improvement in social engagement and coping mechanisms. Choice B, describing anger verbally, may show some progress in emotional expression but does not necessarily indicate overall improvement in depression. Choice C, participating in a job search with a social worker, may be positive but does not directly address social interactions, which are crucial for improving depression. Choice D, denying plans to harm himself or others, is important for safety but does not directly reflect improvement in the client's social functioning or coping skills.

Correct Answer: A

Rationale: The correct instruction the nurse should include in the discharge teaching for a client starting a new antidepressant medication is that "It may take several weeks to notice improvement." This is because antidepressants often require several weeks before the individual starts to feel the full therapeutic effects. Choice B is incorrect because immediate effects are not typically seen with antidepressants. Choice C is incorrect as stopping the medication abruptly can lead to worsening symptoms or withdrawal effects. Choice D is incorrect as open communication with the therapist is crucial for effective management of major depressive disorder.

Correct Answer: A

Rationale: Asking about the amount of sleep a woman gets each night is crucial in understanding her circadian rhythms and how they may affect her quality of life. Circadian rhythms are the body's internal clock that regulates the sleep-wake cycle. Monitoring sleep patterns can provide insights into how well these rhythms are functioning and impacting daily life. Choices B, C, and D are unrelated to circadian rhythms and do not directly assess the effects of these rhythms on quality of life.
