1. What is a surgical procedure where a blood vessel is grafted to bypass a blocked coronary artery, improving blood flow to the heart muscle?

• A. Coronary artery bypass graft (CABG)
• B. Valve replacement
• C. Angioplasty
• D. Endarterectomy

Correct answer: A

Rationale: The correct answer is A: Coronary artery bypass graft (CABG). CABG involves grafting a blood vessel to bypass a blocked coronary artery, enhancing blood flow to the heart muscle. This procedure helps reduce the risk of heart attack by restoring proper blood circulation to the heart. Choice B, valve replacement, is a different surgical procedure that involves replacing damaged or dysfunctional heart valves. Choice C, angioplasty, is a minimally invasive procedure that uses a balloon to open narrowed or blocked blood vessels. Choice D, endarterectomy, is the surgical removal of plaque from the lining of an artery to improve blood flow.

2. The client asks about side effects of taking digoxin. How does the nurse respond?

• A. Anorexia can be a side effect of digoxin.
• B. Tachycardia can be a side effect of digoxin.
• C. Constipation can be a side effect of digoxin.
• D. Urinary retention can be a side effect of digoxin.

Correct answer: A

Rationale: The correct answer is A: 'Anorexia can be a side effect of digoxin.' Anorexia, nausea, vomiting, and diarrhea are commonly known side effects of digoxin. Choice B, 'Tachycardia can be a side effect of digoxin,' is incorrect as digoxin is used to treat tachycardia, not cause it. Choice C, 'Constipation can be a side effect of digoxin,' is incorrect as constipation is not a typical side effect of digoxin. Choice D, 'Urinary retention can be a side effect of digoxin,' is also incorrect as urinary retention is not a common side effect associated with digoxin use.

3. The client on enoxaparin (Lovenox) is scheduled for surgery. What is the nurse’s priority action?

• A. Hold the enoxaparin and notify the healthcare provider.
• B. Administer the enoxaparin as scheduled.
• C. Administer vitamin K before the surgery.
• D. Monitor the client’s INR and proceed with surgery.

Correct answer: A

Rationale: The correct answer is A: Hold the enoxaparin and notify the healthcare provider. Enoxaparin, being an anticoagulant, should be held before surgery to reduce the risk of excessive bleeding during the procedure. It is crucial to inform the healthcare provider to determine the appropriate management plan. Choice B is incorrect because administering enoxaparin before surgery can increase the risk of bleeding. Choice C is incorrect as vitamin K administration is not typically indicated in this situation. Choice D is incorrect because monitoring the client's INR and proceeding with surgery without addressing the enoxaparin can lead to significant bleeding complications.

4. Which term describes an abnormal heartbeat that can be either too fast or too slow?

• A. Arrhythmia
• B. Bradycardia
• C. Tachycardia
• D. Conductivity

Correct answer: A

Rationale: The correct answer is A: Arrhythmia. Arrhythmia is a broad term that refers to any irregularity in the heart's rhythm, which can manifest as a heartbeat that is too fast (tachycardia), too slow (bradycardia), or irregular. Choice B, Bradycardia, specifically denotes a slow heart rate, while choice C, Tachycardia, refers to a fast heart rate. Choice D, Conductivity, is not the correct term to describe an abnormal heartbeat characterized by speed irregularities.

5. Which of the following is a type of heart valve disease where the aortic valve becomes narrowed, restricting blood flow from the heart to the rest of the body?

• A. Aortic stenosis
• B. Mitral stenosis
• C. Tricuspid regurgitation
• D. Pulmonary hypertension

Correct answer: A

Rationale: The correct answer is Aortic stenosis. In aortic stenosis, the aortic valve becomes narrowed, which obstructs the blood flow from the heart to the rest of the body. This condition can lead to symptoms like chest pain, shortness of breath, and fainting. Mitral stenosis (choice B) involves narrowing of the mitral valve, not the aortic valve. Tricuspid regurgitation (choice C) is a condition where the tricuspid valve leaks, causing blood to flow backward in the heart. Pulmonary hypertension (choice D) is high blood pressure in the arteries of the lungs.
