Cardiovascular System Exam Questions And Answers
1. What is the narrowing of the arteries due to the buildup of plaque, which can lead to heart attacks and strokes?
- A. Coronary artery disease
- B. Peripheral artery disease
- C. Aortic stenosis
- D. Mitral valve prolapse
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.
2. What type of medication is used to reduce inflammation in the airways and prevent asthma attacks?
- A. Corticosteroid
- B. Bronchodilator
- C. Antihistamine
- D. Mucolytic
Correct answer: A
Rationale: The correct answer is A, Corticosteroid. Corticosteroids are medications that work by reducing inflammation in the airways, helping to prevent asthma attacks and manage chronic respiratory conditions. Bronchodilators (choice B) work by relaxing the muscles around the airways to make breathing easier, but they do not primarily target inflammation. Antihistamines (choice C) are used to treat allergic reactions and do not directly target airway inflammation. Mucolytics (choice D) help to break down and thin mucus in the airways but do not reduce inflammation.
3. Which valve opens during ventricular systole and closes during ventricular diastole?
- A. Aortic valve
- B. Pulmonary valve
- C. Mitral valve
- D. Tricuspid valve
Correct answer: B
Rationale: The correct answer is B: Pulmonary valve. The pulmonary valve opens during ventricular systole to allow blood to flow from the right ventricle into the pulmonary artery. The aortic valve opens during ventricular systole to allow blood to flow from the left ventricle into the aorta. The mitral valve and tricuspid valve are atrioventricular valves that open during ventricular diastole to allow blood to flow from the atria into the ventricles.
4. What is the condition where the blood flow through the coronary arteries is reduced or blocked, leading to chest pain or heart attack?
- A. Coronary artery disease
- B. Atherosclerosis
- C. Pulmonary embolism
- D. Pulmonary hypertension
Correct answer: A
Rationale: The correct answer is A, Coronary artery disease (CAD). CAD occurs when the coronary arteries are narrowed or blocked, reducing blood flow to the heart muscle and increasing the risk of chest pain or heart attack. Choice B, Atherosclerosis, is a condition characterized by the hardening and narrowing of arteries due to the buildup of plaque. Choices C and D, Pulmonary embolism and Pulmonary hypertension, involve issues related to the lungs and not the coronary arteries.
5. The client is on enalapril (Vasotec) for hypertension. What side effect is most commonly associated with this medication?
- A. Dry cough
- B. Hypotension
- C. Hyperkalemia
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Dry cough. A dry cough is a common side effect of ACE inhibitors like enalapril. ACE inhibitors can cause the accumulation of bradykinin, leading to irritation of the respiratory tract and resulting in a persistent dry cough. Hypotension (choice B) is a possible side effect of ACE inhibitors but is less common than a dry cough. Hyperkalemia (choice C) is another side effect of ACE inhibitors, but it is not the most commonly associated one. Headache (choice D) is not a common side effect of enalapril compared to a dry cough. Therefore, the most commonly associated side effect with enalapril is a dry cough.
