Cardiovascular System Exam Questions Pdf
1. The nurse is caring for a client on amiodarone. What adverse effect is the nurse most concerned about?
- A. Pulmonary toxicity
- B. Liver toxicity
- C. Thyroid dysfunction
- D. Renal dysfunction
Correct answer: A
Rationale: The correct answer is A, Pulmonary toxicity. Amiodarone is known to cause pulmonary toxicity, which can be serious and even fatal in some cases. This adverse effect includes interstitial pneumonitis, pulmonary fibrosis, and acute respiratory distress syndrome. Monitoring for symptoms such as cough, dyspnea, and fever is crucial. Choices B, Liver toxicity, C, Thyroid dysfunction, and D, Renal dysfunction, are incorrect because while amiodarone can also affect the liver, thyroid, and kidneys, the most concerning adverse effect that requires immediate attention and monitoring is pulmonary toxicity.
2. What is the primary effect of a calcium channel blocker on the heart?
- A. Decreases heart rate
- B. Increases heart rate
- C. Increases blood pressure
- D. Decreases blood pressure
Correct answer: D
Rationale: The correct answer is D: Decreases blood pressure. Calcium channel blockers primarily work by relaxing blood vessels, leading to a decrease in blood pressure. While these medications can have secondary effects on the heart, such as reducing the workload of the heart muscle, the primary effect related to blood pressure regulation. Therefore, choices A, B, and C are incorrect as they do not reflect the primary action of calcium channel blockers on the heart.
3. A client on an ACE inhibitor reports a persistent cough. What is the nurse’s best response?
- A. Reassure the client that the cough is a common side effect and is usually not serious.
- B. Instruct the client to report the cough to the healthcare provider as it may require discontinuation of the medication.
- C. Advise the client to use a humidifier at night to relieve the cough.
- D. Suggest the client take an over-the-counter cough suppressant.
Correct answer: B
Rationale: The correct answer is B. A persistent cough in a client on an ACE inhibitor may indicate a serious side effect that requires discontinuation of the medication. Instructing the client to report the cough to the healthcare provider is essential for proper evaluation and management. Choice A is incorrect because simply reassuring the client may delay necessary action. Choice C is incorrect as using a humidifier may not address the underlying cause of the cough. Choice D is incorrect because taking a cough suppressant without healthcare provider guidance may mask symptoms without addressing the cause.
4. This is a test that measures the oxygen saturation level in the blood, often used to assess respiratory function.
- A. Pulse oximetry
- B. Spirometry
- C. Arterial blood gas (ABG)
- D. Lung function test
Correct answer: A
Rationale: The correct answer is A, Pulse oximetry. Pulse oximetry is a non-invasive test that measures the oxygen saturation level in the blood, helping to assess respiratory and cardiovascular function. Choice B, Spirometry, measures lung function by assessing airflow and volume. Choice C, Arterial blood gas (ABG), evaluates the acidity, oxygen, and carbon dioxide levels in the blood. Choice D, Lung function test, is a broad term that may include various tests to assess lung health, but specifically measuring oxygen saturation is done through pulse oximetry.
5. Which procedure is used to remove excess fluid or air from the pleural space, helping to relieve pressure on the lungs?
- A. Thoracentesis
- B. Bronchoscopy
- C. Chest X-ray
- D. Arterial blood gas (ABG)
Correct answer: A
Rationale: The correct answer is Thoracentesis. Thoracentesis is a procedure specifically designed to remove excess fluid or air from the pleural space in the chest. This process helps to relieve pressure on the lungs and improve breathing. Bronchoscopy (Choice B) is a procedure used to visualize the airways and diagnose lung conditions, not to remove fluid from the pleural space. Chest X-ray (Choice C) is an imaging test that provides a picture of the structures inside the chest, including the lungs, heart, and bones. Arterial blood gas (ABG) test (Choice D) is a blood test that measures the levels of oxygen and carbon dioxide in the blood, providing information about how well the lungs are working, but it does not involve removing excess fluid or air from the pleural space.
