1. Which electrolyte imbalance should be closely monitored in a patient receiving digoxin?

A. Monitor potassium levels
B. Monitor sodium levels
C. Monitor calcium levels
D. Monitor glucose levels

Correct answer: A

Rationale: Corrected Rationale: Potassium levels should be monitored closely in a patient receiving digoxin to avoid hypokalemia. Digoxin can increase the risk of developing life-threatening arrhythmias in the presence of low potassium levels. Monitoring sodium, calcium, or glucose levels is not specifically necessary for patients on digoxin, making choices B, C, and D incorrect.

2. A nurse is caring for a client who is receiving enteral nutrition through a nasogastric tube. Which of the following actions should the nurse take?

A. Flush the tube with 30 mL of sterile water before each feeding
B. Administer the feeding using a large-bore syringe
C. Keep the head of the bed elevated to 15 degrees
D. Replace the feeding bag every 24 hours

Correct answer: A

Rationale: The correct action for the nurse to take is to flush the tube with 30 mL of sterile water before each feeding. This helps maintain tube patency and prevents clogs. Choice B is incorrect because enteral feedings should be administered using a gravity drip method or a pump, not through a large-bore syringe. Choice C is incorrect because the head of the bed should be elevated to at least 30 degrees to reduce the risk of aspiration. Choice D is incorrect because the feeding bag should be replaced every 24 hours to prevent bacterial contamination.

3. A nurse is providing discharge teaching to a client who has a new prescription for digoxin. Which of the following statements by the client indicates an understanding of the teaching?

A. I will take my pulse before taking this medication.
B. I should take this medication with food to prevent nausea.
C. I will take this medication if my heart rate is less than 60/min.
D. I should take this medication with food if I am not feeling well.

Correct answer: A

Rationale: The correct answer is A. Taking the pulse before taking digoxin is crucial as it helps monitor the heart rate, as digoxin can cause bradycardia as a side effect. Option B is incorrect because digoxin should be taken on an empty stomach to enhance absorption. Option C is incorrect because digoxin should be held and the healthcare provider should be contacted if the heart rate is less than 60/min. Option D is incorrect because digoxin should not be taken with food due to decreased absorption.

4. How should bleeding in a patient on warfarin be monitored?

A. Monitor INR levels
B. Monitor hemoglobin levels
C. Monitor potassium levels
D. Monitor platelet count

Correct answer: A

Rationale: The correct answer is to monitor INR levels. INR levels are the most critical indicator for monitoring bleeding risk in patients on warfarin. INR stands for International Normalized Ratio and specifically measures the clotting tendency of the blood. Monitoring hemoglobin levels, potassium levels, or platelet count are not as directly relevant to assessing bleeding risk in patients on warfarin.

5. Which lab value is critical for monitoring warfarin therapy?

A. Monitor INR
B. Monitor platelet count
C. Monitor sodium levels
D. Monitor calcium levels

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.
