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 the ability of cardiac cells to respond to an impulse by contracting?

• A. Excitability
• B. Contractility
• C. Rhythmicity
• D. Conductivity

Correct answer: A

Rationale: Excitability is the correct term that describes the ability of cardiac cells to respond to an impulse by contracting. Excitability refers to the cell's ability to respond to stimuli and generate an action potential. Choice B, Contractility, is incorrect as it refers to the ability of cardiac cells to contract after receiving a stimulus, not the response to the impulse itself. Choice C, Rhythmicity, is incorrect as it pertains to the heart's ability to contract rhythmically without external stimulation. Choice D, Conductivity, is incorrect as it refers to the ability of cardiac cells to transmit an impulse from cell to cell, not the direct response to the impulse by contracting.

3. What is the procedure where a device is used to shock the heart back into a normal rhythm during a life-threatening arrhythmia?

• A. Defibrillation
• B. Cardioversion
• C. Echocardiogram
• D. Ablation

Correct answer: A

Rationale: The correct answer is A, Defibrillation. Defibrillation is the procedure of using a device to deliver an electric shock to the heart during life-threatening arrhythmias like ventricular fibrillation or ventricular tachycardia to restore a normal rhythm. Choice B, Cardioversion, is similar but is typically used for less severe arrhythmias. Choice C, Echocardiogram, is a diagnostic test that uses sound waves to create images of the heart. Choice D, Ablation, is a procedure to treat certain types of arrhythmias by scarring or destroying tissue that triggers abnormal electrical signals.

4. 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.

5. Which condition involves the heart muscle becoming abnormally thickened, reducing its ability to pump blood?

• A. Hypertrophic cardiomyopathy
• B. Dilated cardiomyopathy
• C. Restrictive cardiomyopathy
• D. Ischemic cardiomyopathy

Correct answer: A

Rationale: The correct answer is A: Hypertrophic cardiomyopathy. In this condition, the heart muscle thickens, leading to a decreased ability to pump blood effectively. Choice B, Dilated cardiomyopathy, is characterized by the heart chambers enlarging and weakening. Choice C, Restrictive cardiomyopathy, involves the heart muscle becoming rigid and less compliant. Choice D, Ischemic cardiomyopathy, is when the heart muscle is weakened due to reduced blood flow.
