Cardiovascular System Exam

1. Which condition is characterized by fluid collection in the lungs, making it difficult to breathe?

Correct answer: A

Rationale: The correct answer is A, Pulmonary edema. Pulmonary edema is a condition where fluid accumulates in the air sacs of the lungs, causing breathing difficulty. Pleurisy (choice B) is inflammation of the pleura causing chest pain. Pleural effusion (choice C) is the buildup of excess fluid in the pleural space, the area between the layers of tissue that line the lungs and chest cavity. Pneumothorax (choice D) is the presence of air in the pleural space, which can cause a lung to collapse.

2. Which type of medication helps to reduce the workload on the heart by slowing down the heart rate?

Correct answer: A

Rationale: Beta-blockers are medications that work by blocking the action of hormones like adrenaline, thereby reducing the heart rate and the workload on the heart. This makes them effective in managing high blood pressure and various heart conditions. Calcium channel blockers work by relaxing blood vessels and reducing the heart's workload, but they do not primarily slow down the heart rate. Diuretics help the body get rid of excess salt and water by increasing urine production, which can lower blood pressure but not by slowing down the heart rate. ACE inhibitors work by relaxing blood vessels, not by directly affecting heart rate.

3. Which medication relaxes the muscles around the airways, making it easier to breathe?

Correct answer: A

Rationale: The correct answer is A, Bronchodilator. Bronchodilators are medications that relax the muscles surrounding the airways, which helps to open them and makes breathing easier. Corticosteroids (choice B) work by reducing inflammation, antihistamines (choice C) are used to manage allergies, and mucolytics (choice D) help to break down and thin mucus in the airways.

4. What is the narrowing of the arteries due to the buildup of plaque, which can lead to heart attacks and strokes?

Correct answer: A

Rationale: Coronary artery disease is the correct answer. It is the narrowing or blockage of the coronary arteries due to plaque buildup, which can lead to heart attacks and other cardiovascular issues. Choice B, Peripheral artery disease, involves the narrowing of arteries in the limbs, not specifically the coronary arteries. Choice C, Aortic stenosis, refers to the narrowing of the aortic valve opening, not the arteries. Choice D, Mitral valve prolapse, is a condition where the valve between the left atrium and left ventricle doesn't close properly, unrelated to arterial narrowing.

5. Which surgical procedure involves grafting a blood vessel to bypass a blocked artery in the heart?

Correct answer: A

Rationale: The correct answer is A, Coronary artery bypass graft (CABG). This surgical procedure involves grafting a blood vessel to bypass a blocked coronary artery, improving blood flow to the heart muscle. Choice B, Valve replacement, is a procedure to replace a damaged heart valve and is not directly related to bypassing blocked arteries. Choice C, Stent placement, involves inserting a mesh tube to keep blocked arteries open and is different from grafting a blood vessel. Choice D, Angioplasty, is a procedure to widen narrowed or blocked arteries, typically using a balloon catheter, and does not involve grafting a blood vessel.
