Cardiovascular System Exam Questions Pdf
1. What procedure involves using a catheter to create a small scar in the heart tissue to block abnormal electrical signals and restore normal heart rhythm?
- A. Catheter ablation
- B. Angioplasty
- C. Stent placement
- D. Valve replacement
Correct answer: A
Rationale: Catheter ablation is the correct answer. During catheter ablation, a catheter is used to create a small scar in the heart tissue to block abnormal electrical signals, thereby restoring a normal heart rhythm. Choices B, C, and D are incorrect because angioplasty is a procedure to widen narrowed or obstructed arteries, stent placement involves inserting a mesh tube to support a weak artery, and valve replacement is the surgical procedure of replacing a heart valve, none of which match the description provided in the question.
2. Which type of lung cancer is strongly associated with exposure to asbestos?
- A. Mesothelioma
- B. Adenocarcinoma
- C. Squamous cell carcinoma
- D. Small cell lung cancer
Correct answer: A
Rationale: The correct answer is Mesothelioma. This type of lung cancer is indeed strongly associated with exposure to asbestos, affecting the lining of the lungs or abdomen. Adenocarcinoma, Squamous cell carcinoma, and Small cell lung cancer are not primarily linked to asbestos exposure, making them incorrect choices for this question.
3. The nurse is caring for a client on amiodarone who complains of visual disturbances. What is the nurse’s best response?
- A. Notify the healthcare provider immediately.
- B. Reassure the client that this is a common side effect.
- C. Advise the client to monitor their symptoms at home.
- D. Suggest the client reduce physical activity.
Correct answer: A
Rationale: The correct answer is to notify the healthcare provider immediately. Visual disturbances in a client taking amiodarone can indicate amiodarone toxicity, a serious side effect. Notifying the healthcare provider promptly is essential for further assessment and management. Reassuring the client that this is a common side effect (choice B) is incorrect as visual disturbances should not be dismissed without evaluation. Advising the client to monitor their symptoms at home (choice C) may delay necessary intervention. Suggesting the client reduce physical activity (choice D) is unrelated to addressing visual disturbances caused by amiodarone.
4. The client on spironolactone (Aldactone) has a potassium level of 5.6 mEq/L. What is the nurse’s priority action?
- A. Hold the spironolactone and notify the healthcare provider.
- B. Administer potassium supplements.
- C. Continue the spironolactone as ordered.
- D. Increase the dose of spironolactone.
Correct answer: A
Rationale: The correct answer is A: Hold the spironolactone and notify the healthcare provider. A potassium level of 5.6 mEq/L is high, indicating hyperkalemia. Spironolactone is a potassium-sparing diuretic that can further elevate potassium levels. Therefore, the priority action is to withhold the medication to prevent exacerbating hyperkalemia and notify the healthcare provider for further management. Option B is incorrect because administering potassium supplements would worsen the hyperkalemia. Option C is incorrect as continuing spironolactone can lead to a further increase in potassium levels. Option D is incorrect as increasing the dose of spironolactone would be inappropriate in the presence of elevated potassium levels.
5. When administering an ACE inhibitor to a client with heart failure, what is the expected outcome of this medication?
- A. Decreased blood pressure
- B. Increased heart rate
- C. Increased cardiac output
- D. Decreased heart rate
Correct answer: C
Rationale: The correct answer is C: Increased cardiac output. ACE inhibitors are commonly used in heart failure to reduce the workload on the heart by decreasing blood pressure and increasing cardiac output. This ultimately helps improve the heart's efficiency and function. Choice A is incorrect because ACE inhibitors generally lead to a reduction in blood pressure. Choice B is incorrect as ACE inhibitors do not increase heart rate. Choice D is incorrect as ACE inhibitors do not typically decrease heart rate in the context of heart failure.
