1. 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.

2. What is a condition where the heart's mitral valve does not close properly, causing blood to leak backward into the left atrium?

• A. Mitral valve prolapse
• B. Aortic stenosis
• C. Mitral stenosis
• D. Tricuspid regurgitation

Correct answer: A

Rationale: Mitral valve prolapse is the correct answer. It occurs when the mitral valve does not close properly, leading to blood leaking backward into the left atrium. This condition can manifest with symptoms such as palpitations and chest pain. Choices B, C, and D are incorrect because aortic stenosis involves narrowing of the aortic valve, mitral stenosis is the narrowing of the mitral valve, and tricuspid regurgitation is when blood leaks backward through the tricuspid valve.

3. What is a condition where the heart beats too fast, reducing its ability to pump blood effectively?

• A. Tachycardia
• B. Bradycardia
• C. Arrhythmia
• D. Ventricular fibrillation

Correct answer: A

Rationale: Tachycardia is the correct answer because it is a condition characterized by a fast heart rate, which can decrease the heart's efficiency in pumping blood. Bradycardia, on the other hand, refers to a slow heart rate, which is the opposite of what is described in the question. Arrhythmia is a general term for any irregularity in the heart's rhythm, not necessarily specifically related to a fast heart rate. Ventricular fibrillation is a life-threatening arrhythmia where the heart's lower chambers quiver instead of pumping blood effectively, but it is not specifically characterized by a fast heart rate.

4. What type of medication is used to reduce high blood pressure by relaxing the blood vessels?

• A. Calcium channel blocker
• B. Beta-blocker
• C. ACE inhibitor
• D. Diuretic

Correct answer: A

Rationale: Calcium channel blockers are medications that reduce high blood pressure by relaxing the blood vessels, facilitating easier blood flow through the vessels. Beta-blockers work by reducing the heart rate and the heart's workload. ACE inhibitors help relax blood vessels by blocking the production of a chemical that narrows blood vessels. Diuretics help the body get rid of excess sodium and water to lower blood pressure, but they do not directly relax blood vessels like calcium channel blockers do.

5. 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.
