Correct Answer: C

Rationale: The most important nursing problem is medication management (C) because compliance with the medication regimen will help prevent hospitalization. The client is also exhibiting signs of mania, such as excessive work activity (A), decreased need for sleep (B), and inflated self-esteem (D); however, these problems do not have the priority of medication management. Managing the medications is crucial to stabilize the client's condition and prevent potential harm associated with untreated bipolar disorder.

Correct Answer: B

Rationale: The correct answer is B: Weight gain. Olanzapine (Zyprexa) is known to cause significant weight gain in patients. This side effect is crucial to monitor because it can lead to metabolic syndrome, diabetes, and cardiovascular issues. Monitoring the client's weight regularly and providing appropriate dietary guidance is essential. Hypotension (choice A), dry mouth (choice C), and tachycardia (choice D) are not commonly associated with olanzapine use and are not the primary side effects to monitor in this case.

Correct Answer: B

Rationale: The client's disruptive and potentially harmful behavior, including tossing chairs and claiming authority, indicates a risk for other-directed violence. This behavior poses a threat to the safety of the client and others. While the client may have excess energy, the primary concern is the potential for violence, not just a lack of diversional activities (Choice A). The client's behavior is not solely due to hyperactivity leading to activity intolerance (Choice C) or grandiosity affecting personal identity (Choice D), making these options less appropriate in this context.

Correct Answer: B

Rationale: Those with dementia often refer to home or parents when seeking security and comfort. The nurse should use the techniques of 'offering self' and 'talking to the feelings' to provide reassurance (B). Clients with advanced dementia have permanent physiological changes in the brain (plaques and tangles) that prevent them from comprehending and retaining new information, so choices A, C, and D are likely to be of little use to this client and do not address the emotional needs expressed by the client. Option B acknowledges the client's feelings, offers support, and provides reassurance, which can help comfort the client during this distressing time.

Correct Answer: A

Rationale: The correct answer is A. The statement 'I can stop taking this medication once I feel better' indicates a need for further teaching. Antipsychotic medications, like risperidone, should be taken consistently even when symptoms improve to prevent relapse. Choice B is incorrect because avoiding foods high in tyramine is unrelated to risperidone. Choice C is incorrect as avoiding alcohol is a standard precaution with many medications. Choice D is incorrect because being cautious about drowsiness and avoiding driving is a common safety measure associated with risperidone.
