Cardiovascular System Exam Questions And Answers

1. What is a condition where the lung's air sacs become inflamed and fill with fluid or pus, causing cough, fever, chills, and difficulty breathing?

Correct answer: A

Rationale: Pneumonia is the correct answer. It is an infection that inflames the air sacs in one or both lungs, leading to the accumulation of fluid or pus, which results in symptoms such as cough, fever, chills, and difficulty breathing. Tuberculosis (choice B) is a bacterial infection affecting the lungs but does not typically cause the same acute symptoms as described. Asthma (choice C) is a chronic respiratory condition characterized by inflammation and narrowing of the airways, not specifically involving the air sacs. Bronchitis (choice D) is an inflammation of the bronchial tubes, not the air sacs in the lungs, and does not typically cause the same symptoms as pneumonia.

2. This is the inflammation of the heart's inner lining, usually caused by an infection.

Correct answer: A

Rationale: Endocarditis is the inflammation of the inner lining of the heart's chambers and valves, usually caused by a bacterial infection. Myocarditis is the inflammation of the heart muscle, Pericarditis is the inflammation of the pericardium (the outer lining of the heart), and Valvulitis is the inflammation of the heart valves. Therefore, in this case, the correct answer is Endocarditis as it specifically refers to the inflammation of the heart's inner lining.

3. Which test uses sound waves to create images of the heart, allowing doctors to assess its structure and function?

Correct answer: A

Rationale: The correct answer is A: Echocardiogram. An echocardiogram is a test that uses sound waves to create images of the heart, enabling doctors to assess its structure and function. This imaging technique is particularly useful in detecting abnormalities such as valve disease. Choices B, C, and D are incorrect because MRI, CT scans, and X-rays use different imaging technologies that do not rely on sound waves to visualize the heart.

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

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.

5. What is the amount of blood the heart pumps through the circulatory system in a minute?

Correct answer: A

Rationale: The correct answer is A: Cardiac output. Cardiac output is the volume of blood pumped by the heart per minute. It is calculated by multiplying the stroke volume (the amount of blood pumped out of the heart in each beat) by the heart rate (number of heartbeats per minute). This question specifically asks for the total amount of blood pumped through the circulatory system in a minute, which is represented by cardiac output. Choices B, C, and D are incorrect because stroke volume refers to the amount of blood pumped out of the heart in each beat, end-diastolic volume is the volume of blood in the heart at the end of diastole, and ejection fraction is the percentage of blood pumped out of the heart with each contraction, not the total amount pumped per minute.
