Cardiovascular System Practice Exam
1. What is a procedure to remove fluid or air from the pleural space to help a patient breathe easier?
- A. Thoracentesis
- B. Bronchoscopy
- C. Chest X-ray
- D. CT scan
Correct answer: A
Rationale: Correct! Thoracentesis is the correct answer. It is a procedure where fluid or air is removed from the pleural space in the chest to help the patient breathe more easily. Bronchoscopy (choice B) is a procedure to visualize the airways, while Chest X-ray (choice C) and CT scan (choice D) are imaging tests and do not involve the removal of fluid or air from the pleural space.
2. What is the condition where the blood flow through the coronary arteries is reduced or blocked, leading to chest pain or heart attack?
- A. Coronary artery disease
- B. Atherosclerosis
- C. Pulmonary embolism
- D. Pulmonary hypertension
Correct answer: A
Rationale: The correct answer is A, Coronary artery disease (CAD). CAD occurs when the coronary arteries are narrowed or blocked, reducing blood flow to the heart muscle and increasing the risk of chest pain or heart attack. Choice B, Atherosclerosis, is a condition characterized by the hardening and narrowing of arteries due to the buildup of plaque. Choices C and D, Pulmonary embolism and Pulmonary hypertension, involve issues related to the lungs and not the coronary arteries.
3. Which term refers to high blood pressure, a condition where the force of the blood against the artery walls is too high?
- A. Hypertension
- B. Hypotension
- C. Hyperlipidemia
- D. Diabetes
Correct answer: A
Rationale: The correct answer is A, Hypertension. Hypertension is a condition characterized by persistently high blood pressure, which increases the risk of heart disease and stroke. Choice B, Hypotension, refers to low blood pressure. Choice C, Hyperlipidemia, is the term for high levels of fats in the blood. Choice D, Diabetes, is a condition characterized by high blood sugar levels.
4. 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.
5. The client on warfarin has an INR of 4.5. What is the most appropriate action by the nurse?
- A. Administer vitamin K.
- B. Hold the next dose of warfarin.
- C. Increase the dose of warfarin.
- D. Monitor the client’s INR closely.
Correct answer: A
Rationale: An INR of 4.5 is elevated, indicating an increased risk of bleeding due to excessive anticoagulation. The most appropriate action for the nurse in this scenario is to administer vitamin K. Vitamin K helps reverse the anticoagulant effects of warfarin, thus lowering the INR and reducing the risk of bleeding. Holding the next dose of warfarin (choice B) is not sufficient to address the immediate high INR level. Increasing the dose of warfarin (choice C) would further elevate the INR, worsening the risk of bleeding. While monitoring the client's INR closely (choice D) is important, immediate action is required to address the critically high INR level, making the administration of vitamin K the priority intervention.
