Cardiovascular System Practice Exam
1. What procedure involves using a balloon to open a narrowed or blocked blood vessel, often followed by the placement of a stent?
- A. Angioplasty
- B. Valve replacement
- C. Coronary artery bypass graft (CABG)
- D. Endarterectomy
Correct answer: A
Rationale: The correct answer is A, Angioplasty. Angioplasty is a procedure that uses a balloon to open a narrowed or blocked blood vessel, often followed by the placement of a stent to maintain vessel patency. Choice B, Valve replacement, involves replacing damaged heart valves, not treating narrowed blood vessels. Choice C, Coronary artery bypass graft (CABG), is a procedure to bypass blocked coronary arteries, not directly open them using a balloon. Choice D, Endarterectomy, is a surgical procedure to remove plaque from the inner lining of an artery, not involving the use of a balloon and stent to open a vessel.
2. The client is receiving digoxin and complains of nausea. What is the nurse’s priority action?
- A. Check the client’s digoxin level.
- B. Continue the current dose of digoxin.
- C. Administer an antiemetic for nausea.
- D. Discontinue the digoxin immediately.
Correct answer: A
Rationale: The correct answer is to check the client’s digoxin level (Choice A). Nausea can be a sign of digoxin toxicity, so assessing the digoxin level is crucial to determine if the medication dosage needs adjustment. Continuing the current dose of digoxin (Choice B) may worsen the symptoms if toxicity is present. Administering an antiemetic (Choice C) may provide temporary relief but does not address the underlying issue of digoxin toxicity. Discontinuing digoxin immediately (Choice D) without assessing the digoxin level can be harmful if the medication is within the therapeutic range.
3. What is a condition where the lung's air sacs become inflamed and fill with fluid or pus, causing cough, fever, chills, and difficulty breathing?
- A. Pneumonia
- B. Tuberculosis
- C. Asthma
- D. Bronchitis
Correct answer: A
Rationale: Pneumonia is the correct answer. It is an infection that inflames the air sacs in one or both lungs, leading to the accumulation of fluid or pus, which results in symptoms such as cough, fever, chills, and difficulty breathing. Tuberculosis (choice B) is a bacterial infection affecting the lungs but does not typically cause the same acute symptoms as described. Asthma (choice C) is a chronic respiratory condition characterized by inflammation and narrowing of the airways, not specifically involving the air sacs. Bronchitis (choice D) is an inflammation of the bronchial tubes, not the air sacs in the lungs, and does not typically cause the same symptoms as pneumonia.
4. When administering furosemide (Lasix) to a client, which lab value is most important to monitor?
- A. Potassium
- B. Sodium
- C. Calcium
- D. Chloride
Correct answer: A
Rationale: When administering furosemide (Lasix), it is crucial to monitor potassium levels closely. Furosemide is a loop diuretic that can lead to potassium loss, potentially causing hypokalemia. Monitoring potassium levels helps prevent adverse effects associated with low potassium, such as cardiac arrhythmias. While monitoring sodium, calcium, and chloride levels may also be important in certain situations, potassium is the most critical to monitor when administering furosemide.
5. Which medication is used to prevent blood clots by thinning the blood, reducing the risk of stroke and heart attack?
- A. Anticoagulant
- B. ACE inhibitor
- C. Beta-blocker
- D. Calcium channel blocker
Correct answer: A
Rationale: The correct answer is 'Anticoagulant.' Anticoagulants are medications specifically designed to prevent blood clots by thinning the blood, which effectively reduces the risk of stroke, heart attack, and other cardiovascular events. Choices B, C, and D, which are ACE inhibitors, beta-blockers, and calcium channel blockers, respectively, do not have the primary mechanism of action to prevent blood clot formation. ACE inhibitors, beta-blockers, and calcium channel blockers are commonly used for managing hypertension and other cardiovascular conditions by different mechanisms of action.
