Correct Answer: B

Rationale: The correct answer is to assess for signs of bleeding. Warfarin is an anticoagulant that increases the risk of bleeding in patients. Monitoring for signs of bleeding such as easy bruising, petechiae, blood in urine or stool, or unusual bleeding from gums is crucial. Checking the client's blood pressure (choice A) is important but not the priority in this situation. Assessing the client's neurological status (choice C) is essential in stroke patients but is not the priority related to warfarin therapy. Monitoring intake and output (choice D) is important for overall assessment but is not the priority when a client is on warfarin, as assessing for bleeding takes precedence.

Correct Answer: C

Rationale: The correct answer is C: Assessing a client's pain level. This task involves clinical judgment and interpretation, which are within the scope of a licensed nurse's practice. Delegating pain assessment to unlicensed personnel could lead to errors in pain management and inappropriate interventions. Choices A, B, and D involve tasks that can be safely delegated to unlicensed assistive personnel as they do not involve interpretation or nursing judgment. Taking a client's blood pressure, providing oral hygiene, and assisting with ambulation are all routine tasks that can be appropriately assigned to UAP under the supervision of a licensed nurse.

Correct Answer: A

Rationale: The correct action for the nurse to implement is to use a glucometer to check the client's glucose level. Saquinavir, an HIV medication, can lead to hyperglycemia, which may cause symptoms like constant hunger and thirst while losing weight. Checking the glucose level will help assess for hyperglycemia. Choice B is not the priority in this situation as the client's weight loss is a concerning symptom that needs immediate attention. Choice C is incorrect because increasing the medication dose without assessing the glucose level first could exacerbate hyperglycemia. Choice D is incorrect as it does not address the symptoms of constant hunger, thirst, and weight loss, which may indicate a more urgent issue like hyperglycemia.

Correct Answer: D

Rationale: The correct answer is D: Reduced preload. Furosemide is a diuretic that reduces fluid overload in heart failure, which lowers the preload (the volume of blood in the ventricles before contraction). By reducing this volume, furosemide improves symptoms of heart failure. While furosemide may lead to increased urine output and lower blood pressure, these effects are secondary to the reduction in preload. Decreased heart rate is not a direct effect of furosemide in heart failure.

Correct Answer: C

Rationale: Providing warmth can help dilate peripheral vessels and increase blood flow, relieving ischemic pain. In PAD, where there is already compromised blood flow, elevating the legs or applying cold therapy could worsen ischemic pain by further reducing blood flow to the extremities. Encouraging ambulation and leg exercises may be beneficial in other conditions but not suitable for clients with severe PAD experiencing rest ischemia.
