Cardiovascular System Exam Questions And Answers Questions
Question 1 of 5
What is a surgical procedure to replace a damaged or diseased heart valve with a prosthetic valve?
Correct Answer: A
Rationale: The correct answer is A: Valve replacement. This surgical procedure involves replacing a damaged or diseased heart valve with a prosthetic valve to restore proper heart function. It is specifically targeted at addressing heart valve issues, making it the most appropriate choice. Angioplasty (B) is a procedure to open blocked arteries, not related to heart valve replacement. Stent placement (C) involves inserting a mesh tube to keep arteries open, not addressing heart valve issues. Bypass surgery (D) is performed to improve blood flow to the heart muscle, not focused on replacing heart valves. Thus, A is the correct choice for the given question.
Question 2 of 5
Which procedure is used to restore a normal heart rhythm in patients with arrhythmias, typically using electrical shocks?
Correct Answer: A
Rationale: Sure! Cardioversion is the correct answer because it is the procedure used to restore normal heart rhythm in patients with arrhythmias by delivering synchronized electrical shocks. This method is specifically used for irregular heart rhythms that are not immediately life-threatening. Defibrillation, while also using electrical shocks, is used for life-threatening arrhythmias such as ventricular fibrillation. Ablation involves the destruction of abnormal heart tissue causing arrhythmias, and angioplasty is a procedure to open blocked arteries, not related to restoring heart rhythm.
Question 3 of 5
What is a type of medication that helps to prevent blood clots by thinning the blood?
Correct Answer: A
Rationale: The correct answer is A: Anticoagulant. Anticoagulants prevent blood clots by inhibiting the blood's ability to clot. They do not actually thin the blood, but rather prevent clots from forming. Beta-blockers (B), ACE inhibitors (C), and Calcium channel blockers (D) are not used to prevent blood clots. Beta-blockers are used to treat high blood pressure and heart conditions, ACE inhibitors are used to treat high blood pressure and heart failure, and Calcium channel blockers are used to treat high blood pressure and certain heart conditions.
Question 4 of 5
What procedure uses a catheter to open blocked coronary arteries and improve blood flow to the heart muscle?
Correct Answer: A
Rationale: The correct answer is A: Angioplasty. Angioplasty involves using a catheter with a balloon to open blocked coronary arteries, improving blood flow to the heart muscle. The balloon is inflated to compress the plaque against the artery walls, restoring blood flow. Stent placement (B) involves inserting a mesh tube to keep the artery open after angioplasty. CABG (C) is a surgical procedure that uses grafts to bypass blocked coronary arteries. Valve replacement (D) is a procedure to replace damaged heart valves, not specifically for opening blocked coronary arteries.
Question 5 of 5
What is the condition where the arteries in the brain become blocked or narrowed, leading to reduced blood flow and a potential stroke?
Correct Answer: A
Rationale: The correct answer is A: Cerebral atherosclerosis. This condition specifically refers to the buildup of plaque in the arteries supplying the brain, leading to blockages or narrowing. Reduced blood flow in the brain can result in a stroke. Coronary artery disease (B) affects the heart's blood vessels, not the brain. Pulmonary embolism (C) involves a blockage in the arteries of the lungs. Peripheral artery disease (D) affects arteries outside of the heart and brain, usually in the limbs. Therefore, the correct answer is A as it directly relates to the blockages in the brain arteries leading to a potential stroke.
