Correct Answer: A

Rationale: The correct answer is A: "I will avoid aspirin while taking this medication." Clients taking warfarin should avoid aspirin due to the increased risk of bleeding. Choice B is incorrect because increasing the intake of green leafy vegetables high in Vitamin K can interfere with the effects of warfarin. Choice C is incorrect because warfarin should not be taken with antacids as they can decrease its absorption. Choice D is incorrect because mild bruising is a common side effect of warfarin due to its anticoagulant properties.

Correct Answer: D

Rationale: The correct instruction for a client taking furosemide is to take the medication with meals. This helps prevent gastrointestinal upset and improves medication tolerance. Option A is incorrect because furosemide is a loop diuretic that can cause potassium depletion, so avoiding foods high in potassium is not necessary. Option B is incorrect as furosemide typically lowers blood pressure. Option C is incorrect because furosemide is a diuretic that promotes fluid loss rather than retention.

Correct Answer: C

Rationale: The correct answer is C: Clear lung sounds. Clear lung sounds indicate a therapeutic effect of furosemide, as the medication helps reduce fluid overload in heart failure. Choice A, increased shortness of breath, is incorrect as furosemide is used to relieve symptoms like shortness of breath. Choice B, weight gain of 2.3 kg (5 lb), is incorrect as furosemide is a diuretic that helps reduce fluid retention leading to weight loss. Choice D, bounding pulse, is incorrect as furosemide does not directly impact the pulse rate.

Correct Answer: C

Rationale: The correct answer is C: Tachypnea. When caring for a client with pneumonia, the nurse should expect tachypnea, which is rapid breathing. This occurs due to decreased oxygenation and lung function. Bradycardia (A) is not typically associated with pneumonia; instead, tachycardia may be present. Hypertension (B) is not a common manifestation of pneumonia; instead, hypotension may occur due to sepsis. Hypothermia (D) is not a typical finding in pneumonia; fever or an elevated temperature is more common.

Correct Answer: C

Rationale: The correct action the nurse should include in the care plan for a client receiving nitroprusside for severe hypertension is to limit light exposure to the infusion. Nitroprusside is light-sensitive, so it should be protected from light exposure to prevent degradation. Administering calcium gluconate at the bedside is not directly related to nitroprusside administration. Monitoring blood pressure every 2 hours is a good practice but is not specifically related to the administration of nitroprusside. Keeping the client on NPO status is not necessary solely based on receiving nitroprusside.
