1. Which surgical procedure involves opening or replacing a narrowed or blocked heart valve?

• A. Valve replacement
• B. Angioplasty
• C. Stent placement
• D. Coronary bypass surgery

Correct answer: A

Rationale: Valve replacement is the correct answer because it specifically involves surgically replacing a damaged or diseased heart valve with a prosthetic valve to address narrowing or blockage, thereby improving blood flow and heart function. Angioplasty (choice B) is a procedure to widen narrowed or obstructed arteries, typically using a balloon catheter. Stent placement (choice C) involves inserting a mesh tube to support a weakened artery. Coronary bypass surgery (choice D) is a procedure to create new routes for blood flow to the heart muscle by bypassing blocked arteries.

2. Which chronic condition is characterized by abnormally thickened heart muscle, making it harder for the heart to pump blood efficiently?

• A. Hypertrophic cardiomyopathy
• B. Dilated cardiomyopathy
• C. Restrictive cardiomyopathy
• D. Ventricular hypertrophy

Correct answer: A

Rationale: Hypertrophic cardiomyopathy is the correct answer. In this condition, the heart muscle becomes abnormally thickened, leading to difficulties in pumping blood efficiently. Dilated cardiomyopathy (choice B) involves the enlargement of the heart chambers, not thickening of the heart muscle. Restrictive cardiomyopathy (choice C) is characterized by stiffening of the heart muscle, impairing its ability to fill properly. Ventricular hypertrophy (choice D) refers to the thickening of the heart's ventricle walls, which can result from various conditions, not solely hypertrophic cardiomyopathy.

3. A client on a beta blocker has a blood pressure of 90/60 mm Hg. What is the nurse’s priority action?

• A. Hold the beta blocker and notify the healthcare provider.
• B. Administer the beta blocker as ordered.
• C. Administer a diuretic to reduce blood pressure.
• D. Continue to monitor the client and reassess in 30 minutes.

Correct answer: A

Rationale: The correct answer is to hold the beta blocker and notify the healthcare provider. A blood pressure of 90/60 mm Hg is already low, and beta blockers can further decrease blood pressure. Administering the beta blocker can potentially worsen the situation, leading to complications. Administering a diuretic or continuing to monitor the client without taking immediate action could delay necessary intervention. Therefore, holding the beta blocker and involving the healthcare provider promptly is crucial in this scenario.

4. What condition involves a weakened and bulging aorta, the main artery in the body, potentially leading to rupture?

• A. Aortic aneurysm
• B. Arterial stenosis
• C. Pulmonary embolism
• D. Deep vein thrombosis

Correct answer: A

Rationale: An aortic aneurysm is a condition characterized by the weakening and bulging of the aorta, the body's main artery. If left untreated, this bulging may lead to a rupture, causing severe complications. Arterial stenosis refers to the narrowing of an artery, not the weakening and bulging seen in an aortic aneurysm. Pulmonary embolism involves a blockage in the pulmonary artery, which is different from the weakening and bulging in an aortic aneurysm. Deep vein thrombosis is the formation of a blood clot in a deep vein, not related to the condition described in the question.

5. Which type of medication is used to reduce the workload on the heart by slowing down the heart rate and lowering blood pressure?

• A. Beta-blocker
• B. ACE inhibitor
• C. Calcium channel blocker
• D. Diuretic

Correct answer: A

Rationale: The correct answer is A: Beta-blocker. Beta-blockers are medications that reduce the workload on the heart by slowing down the heart rate and lowering blood pressure. They are commonly used in the treatment of heart conditions such as hypertension and heart failure. ACE inhibitors (B) work by dilating blood vessels to reduce blood pressure, calcium channel blockers (C) prevent calcium from entering the heart muscle and blood vessel walls, and diuretics (D) help the body get rid of excess salt and water by increasing urine production.
