1. The nurse is caring for a client on digoxin. What is the most important assessment before administering this medication?

• A. Check the client’s heart rate.
• B. Check the client’s blood pressure.
• C. Check the client’s respiratory rate.
• D. Check the client’s oxygen saturation.

Correct answer: A

Rationale: The correct answer is to check the client’s heart rate before administering digoxin because one of the side effects of digoxin is bradycardia. Monitoring the heart rate is crucial to assess whether the client's heart rate is within the acceptable range before giving the medication. Checking the blood pressure (Choice B), respiratory rate (Choice C), or oxygen saturation (Choice D) are important assessments in general patient care, but they are not specifically related to the administration of digoxin.

2. What is the procedure where a small mesh tube is inserted into an artery to keep it open after angioplasty?

• A. Stent placement
• B. Bypass surgery
• C. Angioplasty
• D. Valve replacement

Correct answer: A

Rationale: The correct answer is A, stent placement. Stent placement involves inserting a small mesh tube into an artery to maintain its openness after angioplasty. This choice is correct because it directly describes the procedure mentioned in the question. Choices B, C, and D are incorrect. Bypass surgery involves rerouting blood flow around a blocked artery using a vessel from another part of the body. Angioplasty is the procedure of widening a narrowed or blocked blood vessel, often followed by stent placement. Valve replacement is a surgical procedure to replace a damaged or diseased heart valve with an artificial or biological valve.

3. The nurse is giving digoxin to a client. What is the most important parameter to check before administration?

• A. Heart rate
• B. Blood pressure
• C. Respiratory rate
• D. Oxygen saturation

Correct answer: A

Rationale: The correct answer is A: Heart rate. Before administering digoxin, it is crucial to check the client's heart rate because digoxin can cause bradycardia, an abnormally slow heart rate. Monitoring the heart rate is essential to prevent potential complications associated with digoxin therapy. Choices B, C, and D are less critical parameters to assess before administering digoxin. While blood pressure is also important to monitor during digoxin therapy, the most crucial parameter to check due to the medication's potential effect on heart rate is the heart rate itself.

4. What is a condition where the heart's ability to pump blood is reduced because the heart muscle is enlarged, thickened, or stiffened?

• A. Cardiomyopathy
• B. Endocarditis
• C. Myocarditis
• D. Aortic stenosis

Correct answer: A

Rationale: Cardiomyopathy is the correct answer. It is a condition characterized by the enlargement, thickening, or stiffening of the heart muscle, leading to a reduced ability of the heart to pump blood effectively. Endocarditis (Choice B) is the inflammation of the inner lining of the heart chambers and valves, not specifically related to the heart muscle. Myocarditis (Choice C) is inflammation of the heart muscle typically caused by a viral infection, not directly related to the heart muscle's structure. Aortic stenosis (Choice D) is a condition characterized by the narrowing of the aortic valve opening, affecting blood flow from the heart's left ventricle to the aorta, different from the structural changes seen in cardiomyopathy.

5. The nurse is administering digoxin to a client. What is the most important parameter to check before administration?

• A. Heart rate
• B. Blood pressure
• C. Respiratory rate
• D. Oxygen saturation

Correct answer: A

Rationale: The correct answer is A: Heart rate. Before administering digoxin, it is crucial to check the client's heart rate because digoxin can cause bradycardia, making it essential to ensure the heart rate is within the appropriate range. Blood pressure, respiratory rate, and oxygen saturation are also important parameters to monitor in a clinical setting, but when administering digoxin, the focus should primarily be on the heart rate due to its potential effects on cardiac function.
