Correct Answer: A

Rationale: When assessing the effectiveness of an antidepressant, improved mood and increased energy are positive indicators that the medication is working. Choice B, increased appetite and weight gain, is more commonly associated with side effects of some antidepressants, such as certain tricyclic antidepressants. Choice C, decreased anxiety and agitation, could be related to the therapeutic effects of antidepressants in treating anxiety disorders but may not specifically indicate the efficacy of the medication for depression. Choice D, enhanced sleep patterns and vivid dreams, while changes in sleep patterns can be influenced by antidepressants, they are not the primary indicators of antidepressant efficacy. Therefore, the correct choice is A as it directly reflects the desired outcomes of antidepressant therapy.

Correct Answer: A

Rationale: Assessing the history of recent drug use is crucial when admitting a client with a history of substance abuse. Understanding recent drug use helps in managing potential withdrawal symptoms, preventing drug interactions with the new treatment, and ensuring appropriate care. Assessing current employment status (choice B) is important for social and financial support but is not as crucial as assessing recent drug use in this scenario. Family history of mental illness (choice C) and recent weight changes (choice D) are also important aspects of assessment but are not as immediate and critical as evaluating recent drug use in a client with a history of substance abuse.

Correct Answer: A

Rationale: Diarrhea, vomiting, and drowsiness in a client being treated with lithium carbonate for bipolar disorder may indicate lithium toxicity. The nurse should promptly notify the healthcare provider to ensure immediate medical intervention. The correct action is to prepare for the administration of an antidote if necessary. Holding the medication (Choice B) could delay necessary treatment. Considering the symptoms as normal side effects (Choice C) is incorrect as they suggest a potential serious issue. Notifying the healthcare provider before the next administration of the drug (Choice D) may delay urgent intervention required for lithium toxicity.

Correct Answer: C

Rationale: Observing the client for further narcotic effects is the priority at this time. It is crucial to monitor the client closely to prevent a relapse of symptoms or potential complications from the overdose. Encouraging fluid intake, obtaining serum Vicodin levels, and determining the reason for the suicide attempt are important but are secondary to ensuring the client's immediate safety and well-being by observing for any lingering effects of the narcotic.

Correct Answer: D

Rationale: Echolalia, the constant repetition of what others are saying, can be disruptive to the therapeutic environment. The most appropriate intervention is to escort the client to his room. This action provides the client with a private space where he can engage in the behavior without disturbing other clients. Avoiding recognition of the behavior (Choice A) may not address the issue and could lead to increased annoyance among other clients. Isolating the client (Choice B) may have negative psychological effects and should be avoided unless absolutely necessary for safety concerns. Administering a PRN sedative (Choice C) should be considered only as a last resort and if other de-escalation techniques have been unsuccessful.
