Cardiovascular System Practice Exam
1. The nurse is caring for a client on warfarin with an INR of 1.8. What is the most appropriate action?
- A. Increase the dose of warfarin.
- B. Administer vitamin K.
- C. Hold the warfarin and notify the healthcare provider.
- D. Monitor the client’s INR closely.
Correct answer: D
Rationale: An INR of 1.8 is below the therapeutic range for a client on warfarin, indicating the need for monitoring closely to ensure that the INR levels reach the desired therapeutic range. Increasing the dose of warfarin (Choice A) without proper monitoring may lead to an increased risk of bleeding. Administering vitamin K (Choice B) is not typically recommended unless the client is experiencing major bleeding or requires rapid reversal of warfarin's effects. Holding the warfarin and notifying the healthcare provider (Choice C) may be necessary in certain situations, but the immediate action in this case should be to monitor the client's INR closely to guide further management.
2. Which of the following is a chronic respiratory disease characterized by the irreversible obstruction of airflow?
- A. Chronic obstructive pulmonary disease (COPD)
- B. Asthma
- C. Pulmonary edema
- D. Bronchiectasis
Correct answer: A
Rationale: The correct answer is A, Chronic obstructive pulmonary disease (COPD). COPD is a chronic respiratory disease where the airflow in the lungs becomes obstructed, making it difficult to breathe. Choice B, Asthma, is a different chronic respiratory condition characterized by reversible airflow obstruction and airway hyperresponsiveness. Choice C, Pulmonary edema, is a condition where fluid accumulates in the lungs, leading to difficulty in breathing but not irreversible airflow obstruction. Choice D, Bronchiectasis, is a condition characterized by abnormal widening of the bronchial tubes, leading to recurrent respiratory infections, but it is not specifically defined by irreversible airflow obstruction.
3. What type of imaging test uses X-rays to visualize the blood vessels after injecting them with a contrast dye?
- A. Angiography
- B. CT scan
- C. MRI
- D. Ultrasound
Correct answer: A
Rationale: Angiography is the correct answer because it is an imaging test that specifically uses X-rays to visualize blood vessels by injecting them with a contrast dye. This procedure is crucial for diagnosing conditions such as blockages or aneurysms. The other options, CT scan, MRI, and ultrasound, do not involve the use of contrast dye to visualize blood vessels with X-rays.
4. The client on amiodarone reports shortness of breath. 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. Instruct the client to monitor their symptoms at home.
- D. Suggest the client reduce physical activity.
Correct answer: A
Rationale: When a client on amiodarone reports shortness of breath, it can be indicative of pulmonary toxicity, a severe side effect associated with this medication. The nurse's priority is to notify the healthcare provider immediately to assess the situation and determine the appropriate course of action. Choice B is incorrect because shortness of breath with amiodarone should not be dismissed as a common side effect. Instructing the client to monitor symptoms at home (Choice C) may delay necessary intervention. Suggesting the client reduce physical activity (Choice D) does not address the potential serious nature of the symptom and the need for prompt evaluation.
5. Which artery supplies the anterior wall of the left ventricle, the anterior interventricular septum, the anterior papillary muscles, and apex of the heart?
- A. Left anterior descending artery
- B. Left circumflex artery
- C. Posterior descending artery
- D. Aortic artery
Correct answer: A
Rationale: The correct answer is the Left anterior descending artery. This artery supplies the anterior wall of the left ventricle, the anterior interventricular septum, the anterior papillary muscles, and apex of the heart. The Left circumflex artery (choice B) supplies the lateral and posterior walls of the left ventricle, the posterior descending artery (choice C) supplies the inferior part of the heart, and the aortic artery (choice D) is not a specific coronary artery.
