Correct Answer: A

Rationale: Administering diuretics is the best method to manage fluid overload in a patient with heart failure. Diuretics help to remove excess fluid from the body by increasing urine output, thus reducing the fluid volume in the bloodstream and tissues. Providing oral fluids (choice B) or increasing fluid intake (choice C) would exacerbate the fluid overload rather than managing it. Chest physiotherapy (choice D) is not indicated for managing fluid overload in heart failure; it is more commonly used for conditions affecting the lungs or airways.

Correct Answer: A

Rationale: The correct initial intervention for a patient with chest pain is to administer aspirin. Aspirin helps reduce the risk of clot formation by inhibiting platelet aggregation, which can be beneficial in case the chest pain is due to a cardiac event. Administering nitroglycerin may follow aspirin administration to help relieve chest pain by dilating blood vessels. Providing pain relief is a general approach and may not address the underlying cause of chest pain. Preparing for surgery would not be the initial intervention for chest pain unless there are specific indications for immediate surgical intervention.

Correct Answer: C

Rationale: The correct answer is C: Fever. When a client is taking clozapine, fever can indicate serious conditions such as infection or severe reactions, which need immediate medical attention. Constipation (choice A), blurred vision (choice B), and dry mouth (choice D) are common side effects of clozapine but are not as urgent as fever. Constipation can be managed with dietary changes or medications, blurred vision can improve over time, and dry mouth can be relieved with frequent sips of water.

Correct Answer: B

Rationale: The correct instruction for a client taking furosemide is to increase their intake of potassium-rich foods. Furosemide is a loop diuretic that can lead to potassium loss, so increasing potassium-rich foods helps prevent hypokalemia. Choice A is incorrect because furosemide is usually taken on an empty stomach. Choice C is unrelated to furosemide therapy. Choice D is incorrect as there is no need to limit calcium-rich foods while taking furosemide.
