Correct Answer: A

Rationale: The correct answer is A: "It may take 4-6 weeks for the medication to be effective." SSRIs like fluoxetine typically take 4-6 weeks to reach their full effect, so clients should be informed to expect a gradual improvement in symptoms. Choice B is incorrect because fluoxetine is usually taken in the morning to prevent sleep disturbances. Choice C is incorrect as there is no specific need to avoid consuming dairy products while taking fluoxetine. Choice D is incorrect because clients should never stop taking antidepressants abruptly, as it can lead to withdrawal symptoms and worsening of the condition.

Correct Answer: B

Rationale: The most important teaching point for a client prescribed alprazolam is not to stop taking the medication abruptly. Abruptly stopping alprazolam, a benzodiazepine, can lead to withdrawal symptoms. It is crucial to taper off the medication under medical supervision to prevent adverse effects. Choice A is incorrect because taking the medication at the first sign of anxiety is not the key teaching point. Choice C is incorrect because weight gain is not a common side effect of alprazolam. Choice D is incorrect because vivid dreams are not a significant concern compared to the risks of abrupt discontinuation of the medication.

Correct Answer: C

Rationale: The most important assessment to perform for a client on a methadone maintenance program is to evaluate the client's respiratory status. Methadone can cause respiratory depression as a side effect, making it crucial to monitor the client's breathing to prevent potential complications. Monitoring for signs of withdrawal (choice A) is important but not the most critical in this scenario. Assessing for signs of methadone toxicity (choice B) is relevant, but respiratory status takes precedence due to the risk of respiratory depression. Checking the client's blood pressure regularly (choice D) is important for overall assessment but is not as crucial as monitoring respiratory status in this case.

Correct Answer: B

Rationale: The most important nursing intervention during the first 48 hours for a client with anorexia nervosa is monitoring vital signs and electrolytes (B) to assess for life-threatening complications. This helps in early detection of any physiological imbalances that could lead to serious consequences. Providing high-calorie, high-protein meals (A) is important for nutritional rehabilitation but comes after ensuring the client's physical stability. Encouraging the client to talk about feelings (C) and observing for signs of purging (D) are relevant aspects of care but are not as critical as monitoring vital signs and electrolytes in the initial phase of treatment.

Correct Answer: A

Rationale: Overeaters Anonymous is a self-help group characterized by shared goals among members to address eating disorders. This provides a supportive environment for personal change and growth. Choice B is incorrect as members are not required to remain anonymous in Overeaters Anonymous. Choice C is incorrect as the leader in such self-help groups is usually a member who has experienced similar issues, not necessarily a professional mental health care provider. Choice D is incorrect as attendance at Overeaters Anonymous meetings is voluntary and not prescribed by a healthcare provider.
