Cardiovascular System Exam Questions And Answers
1. Which test measures how well the lungs work by assessing the amount of air the lungs can hold and how quickly air can be exhaled?
- A. Spirometry
- B. Pulse oximetry
- C. Arterial blood gas (ABG)
- D. Chest X-ray
Correct answer: A
Rationale: The correct answer is A, Spirometry. Spirometry is a pulmonary function test that evaluates lung function by measuring the amount of air a person can exhale and how quickly, assisting in the diagnosis of conditions such as asthma and COPD. Choices B, C, and D are incorrect because Pulse oximetry measures oxygen saturation in the blood, Arterial blood gas (ABG) evaluates blood pH, oxygen, and carbon dioxide levels, and a Chest X-ray provides an image of the lungs but does not measure lung function.
2. 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.
3. What is a condition where the heart beats too slowly, reducing the amount of blood pumped to the body?
- A. Bradycardia
- B. Tachycardia
- C. Atrial fibrillation
- D. Ventricular fibrillation
Correct answer: A
Rationale: Bradycardia is the correct answer. It is a condition characterized by a slow heart rate, which reduces the amount of blood pumped to the body. This can lead to symptoms like fatigue and dizziness. Choice B, Tachycardia, is the opposite condition where the heart beats too fast. Choices C and D, Atrial fibrillation and Ventricular fibrillation, refer to irregular and potentially life-threatening rapid heart rhythms involving the atria and ventricles respectively, not a slow heart rate.
4. In cases of myocardial infarction leading to shock, which medication is appropriate to counteract shock?
- A. Atropine
- B. Dopamine
- C. Digoxin
- D. Adenosine
Correct answer: B
Rationale: In cases of myocardial infarction leading to shock, dopamine is the drug of choice. Dopamine helps increase blood pressure and improve blood flow to vital organs, making it beneficial in managing shock. Atropine is mainly used for symptomatic bradycardia, not for shock. Digoxin is a cardiac glycoside used in heart failure and atrial fibrillation, not for managing shock. Adenosine is typically used for diagnosing and treating supraventricular tachycardias, not for shock associated with myocardial infarction.
5. What is an acute respiratory infection that inflames the alveoli in one or both lungs, causing them to fill with fluid or pus?
- A. Pneumonia
- B. Bronchitis
- C. Tuberculosis
- D. Asthma
Correct answer: A
Rationale: Pneumonia is the correct answer because it is an acute respiratory infection that inflames the alveoli in one or both lungs, leading to the accumulation of fluid or pus. This condition presents with symptoms like cough, fever, and difficulty breathing. Bronchitis is the inflammation of the bronchial tubes, not the alveoli. Tuberculosis is a bacterial infection that primarily affects the lungs but does not always result in alveolar inflammation. Asthma is a chronic respiratory condition characterized by airway inflammation and narrowing, not alveolar inflammation.
