A client with Alzheimer's disease is exhibiting signs of agitation and aggression. What is the nurse's priority intervention?

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: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

Correct Answer: A

Rationale: The correct answer is A: 'Monitor the client's hemoglobin and hematocrit.' When a client with chronic kidney disease is prescribed erythropoietin, the nurse's priority action is to monitor the client's hemoglobin and hematocrit. Erythropoietin stimulates red blood cell production, so monitoring these lab values helps evaluate the effectiveness of erythropoietin in treating anemia. Monitoring the client's blood pressure (choice B) is important but not the priority in this scenario. Assessing the client for signs of infection (choice C) is important but not the priority related to the prescription of erythropoietin. Monitoring the client for signs of bleeding (choice D) is relevant but not the priority action when erythropoietin is prescribed.

Correct Answer: C

Rationale: The correct answer is C: 'Decreased edema and improved peripheral pulses.' In a client with heart failure, furosemide is a diuretic that helps reduce fluid overload. Therefore, a decrease in edema (swelling due to fluid retention) and improved peripheral pulses (indicating better circulation) are signs that the medication is effective. Choices A, B, and D are incorrect. Increased urine output and weight loss (Choice A) may indicate the diuretic effect of furosemide but do not specifically reflect its effectiveness in heart failure. Increased heart rate and blood pressure (Choice B) are not desired effects of furosemide and may suggest adverse reactions. Decreased shortness of breath and clear lung sounds (Choice D) are related to improved respiratory status and may not directly reflect the effectiveness of furosemide in addressing fluid overload.

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.
