Correct Answer: C

Rationale: Encouraging the client to take frequent rest periods is an appropriate intervention for managing mania in a client with bipolar disorder. During a manic episode, individuals often have increased energy levels, decreased need for sleep, and may engage in high-risk behaviors. Encouraging regular rest periods can help reduce stimulation and promote relaxation, which may assist in stabilizing mood. Choices A and B are not as effective in managing manic symptoms, as they do not directly address the client's need for rest and relaxation. Choice D is inappropriate because placing the client in seclusion can increase feelings of anxiety and agitation, worsening the manic episode.

Correct Answer: B

Rationale: Administering flumazenil is the priority to reverse the effects of diazepam overdose. Flumazenil is a specific benzodiazepine receptor antagonist that can rapidly reverse the sedative effects of diazepam. Monitoring the IV site for thrombophlebitis is important but not the immediate priority in this situation. Evaluating the client for further suicidal behavior is important for comprehensive care but is not the most urgent action at this moment. Initiating seizure precautions may be necessary, but the priority is to counteract the sedative effects of diazepam with flumazenil.

Correct Answer: C

Rationale: In caring for a client with schizophrenia experiencing delusions, it is essential to focus on the client's feelings rather than directly addressing or challenging the delusions. By focusing on the client's emotions, the nurse can build trust and rapport without reinforcing the delusions. Choice A is incorrect because directly telling the client that their delusions are not real may lead to confrontation or mistrust. Choice B is incorrect as encouraging exploration of the delusions may further validate them. Choice D is incorrect because challenging the client's delusions can escalate the situation and damage the therapeutic relationship.

Correct Answer: A

Rationale: A continuous murmur is a classic finding in a newborn with patent ductus arteriosus. This murmur is typically heard between the first and second heart sounds and throughout systole. Absent peripheral pulses (choice B) are not typically associated with patent ductus arteriosus. Increased blood pressure (choice C) and bounding pulses (choice D) are not commonly seen with this condition. Therefore, the correct answer is A.

Correct Answer: A

Rationale: The correct answer is to obtain the specimen immediately upon the client waking up. Collecting sputum early in the morning provides the best sample for tuberculosis testing. Option B is incorrect because waiting a day can decrease the accuracy of the specimen. Option C is incorrect as it does not specify the optimal timing for specimen collection. Option D is incorrect as sterile gloves should be worn for infection control but do not specifically relate to the timing of specimen collection.
