Correct Answer: B

Rationale: The correct answer is to redirect the client to a quiet activity. This intervention helps reduce agitation and aggression in clients with Alzheimer's disease by providing a distraction and promoting a calming environment. Reassuring the client and providing emotional support (Choice A) can be beneficial but is not the priority in this situation. Administering a PRN dose of lorazepam (Choice C) should not be the first intervention due to the risk of adverse effects and should only be considered if other non-pharmacological interventions are ineffective. Applying restraints (Choice D) should be avoided unless absolutely necessary for the client's safety as it can lead to further distress and is not the initial priority intervention.

Correct Answer: C

Rationale: For clients with peripheral artery disease, advising the client to take a short break when leg cramps occur and then continue walking is the appropriate intervention. This approach, known as interval walking, helps manage pain from intermittent claudication and improves circulation over time. Choice A is incorrect because immediate rest may not be necessary, and encouraging the client to resume walking after a short break is more beneficial. Choice B is incorrect since increasing potassium-rich foods may not directly address the underlying issue of peripheral artery disease causing cramps. Choice D is incorrect as avoiding walking altogether can lead to further deconditioning and worsen symptoms over time.

Correct Answer: D

Rationale: In this scenario, the most important intervention for a male client with schizophrenia who is diaphoretic and pacing the hallway is to carefully observe the client throughout the shift. Diaphoresis and pacing can be indicators of agitation or distress in clients with schizophrenia. Careful observation is crucial to monitor the client's safety, assess for any potential escalation of symptoms, and provide timely intervention if needed. Taking the client's temperature and blood pressure (Choice A) may not address the immediate need for safety and observation. Encouraging the client to rest (Choice B) may not be effective if the client is agitated. Planning an activity involving physical exercise (Choice C) could potentially exacerbate the situation rather than addressing the immediate need for observation and safety.

Correct Answer: B

Rationale: An S3 heart sound is often a normal finding in pregnant women due to increased blood volume and cardiac output. The nurse should document the finding as part of the routine assessment unless accompanied by other abnormal symptoms. Performing a 12-lead electrocardiogram (Choice A) is unnecessary for a normal S3 heart sound in pregnancy. Notifying the healthcare provider immediately (Choice C) is premature and may lead to unnecessary interventions. Assessing for signs of heart failure (Choice D) is not indicated as an isolated S3 heart sound is typically benign in pregnancy.

Correct Answer: A

Rationale: The correct answer is to monitor the client's potassium level. During hemodialysis, there is a risk of potassium shifting, which can lead to life-threatening arrhythmias if not properly managed. Assessing the potassium level is crucial to prevent complications. While assessing blood pressure, checking hemoglobin and hematocrit levels, and monitoring for signs of infection are important aspects of care for a client with chronic kidney disease, monitoring potassium levels takes precedence due to its immediate life-threatening potential post-dialysis.
