1. What is the condition where the arteries in the brain become blocked or narrowed, leading to reduced blood flow and a potential stroke?

• A. Cerebral atherosclerosis
• B. Coronary artery disease
• C. Pulmonary embolism
• D. Peripheral artery disease

Correct answer: A

Rationale: Cerebral atherosclerosis is the correct answer. It is a condition where the arteries in the brain become blocked or narrowed due to plaque buildup, leading to reduced blood flow and an increased risk of stroke. Choice B, Coronary artery disease, specifically affects the arteries supplying blood to the heart, not the brain. Choice C, Pulmonary embolism, involves a blockage in the pulmonary artery that affects blood flow to the lungs, not the brain. Choice D, Peripheral artery disease, refers to a condition where blockages occur in arteries outside of the heart and brain, typically affecting the limbs.

2. What is a condition where the coronary arteries become narrowed or blocked, leading to reduced blood flow to the heart muscle?

• A. Coronary artery disease (CAD)
• B. Atherosclerosis
• C. Stroke
• D. Peripheral artery disease

Correct answer: A

Rationale: The correct answer is A, Coronary artery disease (CAD). CAD is a condition where the coronary arteries become narrowed or blocked, leading to reduced blood flow to the heart muscle and an increased risk of heart attack. Choice B, Atherosclerosis, is a related condition involving the buildup of fats, cholesterol, and other substances in and on the artery walls, but it is not specific to the coronary arteries. Choices C and D, Stroke and Peripheral artery disease, respectively, involve different arteries and conditions, not directly related to the narrowing or blockage of the coronary arteries.

3. What procedure uses a catheter to open up a blocked or narrowed coronary artery, often involving the placement of a stent?

• A. Angioplasty
• B. Echocardiogram
• C. CT angiography
• D. Coronary artery bypass graft (CABG)

Correct answer: A

Rationale: The correct answer is Angioplasty. Angioplasty is a procedure that uses a catheter to open up a blocked or narrowed coronary artery, often involving the placement of a stent. Echocardiogram is a diagnostic test that uses sound waves to create images of the heart. CT angiography is a type of imaging test that looks at blood vessels, but it does not involve the placement of a stent. Coronary artery bypass graft (CABG) is a surgical procedure to improve blood flow to the heart muscle by bypassing blocked coronary arteries.

4. What is a surgical procedure to replace a damaged or diseased heart valve with a prosthetic valve?

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

Correct answer: A

Rationale: Valve replacement is the correct answer because it involves replacing a damaged or diseased heart valve with a prosthetic valve. This procedure is essential for improving blood flow and heart function. Angioplasty (choice B) is a procedure to widen narrowed or obstructed arteries. Stent placement (choice C) involves inserting a mesh tube to help support weak arteries. Bypass surgery (choice D) is a procedure to create new routes for blood flow when arteries are blocked.

5. The client on warfarin has an INR of 3.8. What is the most appropriate action by the nurse?

• A. Administer vitamin K.
• B. Hold the next dose of warfarin.
• C. Increase the dose of warfarin.
• D. Notify the healthcare provider immediately.

Correct answer: A

Rationale: An INR of 3.8 is elevated, indicating an increased risk of bleeding. Administering vitamin K can help reverse the effects of warfarin. Holding the next dose of warfarin would be appropriate if the INR was too high, but not as the first-line action. Increasing the dose of warfarin would worsen the situation by further increasing the INR. Notifying the healthcare provider is important, but immediate action to address the elevated INR is necessary.
