1. What procedure uses a balloon to open narrowed or blocked blood vessels in the heart?

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

Correct answer: A

Rationale: The correct answer is Angioplasty. Angioplasty is a procedure that involves using a balloon to open narrowed or blocked blood vessels in the heart, thereby improving blood flow. This choice is correct because it directly matches the description provided in the question. Choices B, C, and D are incorrect because they involve different procedures: Bypass graft is a surgical procedure to redirect blood flow, stent placement involves inserting a mesh tube to keep an artery open, and valve replacement is the surgical replacement of a heart valve.

2. Identify the three layers of the heart:

• A. Endocardium, Myocardium, Epicardium
• B. Epicardium, Pericardium, Endocardium
• C. Myocardium, Endocardium, Pericardium
• D. Pericardium, Myocardium, Endocardium

Correct answer: A

Rationale: The correct answer is A: Endocardium, Myocardium, Epicardium. The heart consists of three main layers: the endocardium, which lines the inner chambers of the heart; the myocardium, the middle layer responsible for the heart's pumping action; and the epicardium, the outermost layer that protects the heart. Choices B, C, and D are incorrect as they do not list the heart's layers in the correct order or combination.

3. What type of stroke is caused by a blockage in an artery supplying blood to the brain?

• A. Ischemic stroke
• B. Hemorrhagic stroke
• C. Transient ischemic attack
• D. Embolism

Correct answer: A

Rationale: The correct answer is A: Ischemic stroke. Ischemic stroke occurs when a blood clot blocks an artery supplying blood to the brain, leading to brain damage. Choice B, Hemorrhagic stroke, is caused by bleeding in the brain, not a blockage. Choice C, Transient ischemic attack, is a temporary blockage of blood flow to the brain with symptoms similar to a stroke but typically lasting only a few minutes. Choice D, Embolism, refers to a blood clot or other particle that travels through the bloodstream and blocks a blood vessel.

4. What is a condition characterized by an abnormal buildup of fluid between the layers of tissue lining the lungs and chest cavity?

• A. Pleural effusion
• B. Pulmonary edema
• C. Atelectasis
• D. Sarcoidosis

Correct answer: A

Rationale: Pleural effusion is the correct answer as it refers to the accumulation of excess fluid between the layers of the pleura surrounding the lungs and chest cavity. This condition can be caused by various factors such as infections, heart failure, or cancer. Pulmonary edema (choice B) involves fluid accumulation in the lungs' air sacs and is not specific to the pleura. Atelectasis (choice C) is the collapse or closure of a lung leading to airless lung tissue and is not related to fluid buildup. Sarcoidosis (choice D) is a condition characterized by the growth of tiny collections of inflammatory cells in different parts of the body, not specifically involving fluid accumulation in the pleural space.

5. Which term refers to a condition where the blood supply to part of the heart muscle is blocked, often referred to as a heart attack?

• A. Myocardial infarction
• B. Arrhythmia
• C. Stroke
• D. Aneurysm

Correct answer: A

Rationale: The correct answer is A, myocardial infarction. A myocardial infarction, commonly known as a heart attack, occurs when the blood supply to part of the heart muscle is blocked, often by a blood clot. Choices B, C, and D are incorrect because arrhythmia refers to an irregular heartbeat, stroke involves the interruption of blood flow to the brain, and an aneurysm is a bulge in a blood vessel.
