1. What condition is characterized by the inflammation of the heart's outer lining, often causing chest pain and other symptoms?

Correct answer: A

Rationale: Pericarditis is the correct answer because it is the inflammation of the pericardium, the outer lining of the heart. This condition commonly presents with symptoms like chest pain. Endocarditis (choice B) is the inflammation of the inner lining of the heart chambers and valves. Myocarditis (choice C) is the inflammation of the heart muscle itself. Valvular heart disease (choice D) refers to various conditions affecting the heart valves, not specifically the outer lining of the heart.

2. Which structure serves as the normal pacemaker of the heart?

Correct answer: A

Rationale: The correct answer is the SA node. The sinoatrial (SA) node is known as the natural pacemaker of the heart as it generates electrical impulses initiating each heartbeat. The SA node is located in the right atrium and sets the rhythm and rate of the heartbeat. The AV node (choice B) is responsible for delaying the electrical impulse to allow the atria to contract before the ventricles. Purkinje fibers (choice C) are specialized cardiac fibers responsible for the rapid conduction of impulses to the myocardial cells, and the atria (choice D) are the upper chambers of the heart involved in receiving blood from the veins.

3. What is a condition where the alveoli are gradually destroyed, leading to shortness of breath and reduced oxygen exchange?

Correct answer: A

Rationale: The correct answer is A: Emphysema. Emphysema is a chronic lung condition where the alveoli (air sacs) in the lungs are damaged, reducing the surface area available for gas exchange. This destruction leads to symptoms like shortness of breath and reduced oxygen exchange. Choice B, pulmonary fibrosis, involves scarring and thickening of the lung tissue, not destruction of alveoli. Choice C, pulmonary edema, is the accumulation of fluid in the lungs, not destruction of alveoli. Choice D, lung cancer, is the uncontrolled growth of abnormal cells in the lungs, not destruction of alveoli.

4. The nurse is caring for a client on amiodarone who complains of visual disturbances. What is the nurse’s best response?

Correct answer: A

Rationale: The correct answer is to notify the healthcare provider immediately. Visual disturbances in a client taking amiodarone can indicate amiodarone toxicity, a serious side effect. Notifying the healthcare provider promptly is essential for further assessment and management. Reassuring the client that this is a common side effect (choice B) is incorrect as visual disturbances should not be dismissed without evaluation. Advising the client to monitor their symptoms at home (choice C) may delay necessary intervention. Suggesting the client reduce physical activity (choice D) is unrelated to addressing visual disturbances caused by amiodarone.

5. The client is on spironolactone (Aldactone). What is the most important dietary instruction?

Correct answer: A

Rationale: The correct answer is to avoid foods high in potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium and can lead to hyperkalemia if too much potassium is consumed. Choices B, C, and D are incorrect because increasing intake of potassium-rich foods can worsen hyperkalemia, while avoiding foods high in sodium is not the primary concern when taking spironolactone.
