1. 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.

2. Which lab value is most critical to monitor in a patient receiving digoxin?

• A. Monitor potassium levels
• B. Monitor sodium levels
• C. Monitor calcium levels
• D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels in a patient receiving digoxin. Hypokalemia can potentiate the toxic effects of digoxin, leading to serious cardiac arrhythmias. Monitoring potassium levels helps prevent toxicity. Monitoring sodium levels (Choice B), calcium levels (Choice C), and magnesium levels (Choice D) are also important aspects of patient care, but potassium levels are most critical in patients on digoxin therapy.

3. A client has a new prescription for digoxin. Which of the following instructions should the nurse include?

• A. Take this medication at bedtime to prevent nausea.
• B. Take this medication with a full glass of milk.
• C. Notify your provider if you experience visual disturbances.
• D. Report any muscle pain to your provider.

Correct answer: C

Rationale: The correct answer is C: 'Notify your provider if you experience visual disturbances.' Visual disturbances can indicate digoxin toxicity, so it is essential for clients taking digoxin to report any changes in vision to their healthcare provider. Option A is incorrect because the timing of digoxin administration is crucial, usually in the morning. Option B is inaccurate because digoxin should not be taken with milk as it can affect its absorption. Option D is not directly associated with digoxin use and should not be the priority instruction for a client on this medication.

4. A nurse is reviewing the medical record of a client who has major depressive disorder and is taking tranylcypromine. Which of the following foods should the nurse instruct the client to avoid?

• A. Milk
• B. Bananas
• C. Yogurt
• D. Cured meats

Correct answer: D

Rationale: The correct answer is D: Cured meats. Cured meats contain tyramine, which can lead to a hypertensive crisis in clients taking tranylcypromine. Bananas, milk, and yogurt do not contain significant amounts of tyramine and are safe for clients taking this medication. Therefore, the nurse should instruct the client to avoid cured meats to prevent adverse effects.

5. A nurse is preparing to administer medications to a client who has a nasogastric (NG) tube. Which of the following actions should the nurse take first?

• A. Check for tube placement.
• B. Flush the NG tube with 0.9% sodium chloride.
• C. Administer the medications as a bolus.
• D. Dissolve the medications in 30 mL of sterile water.

Correct answer: A

Rationale: The correct first action for the nurse to take when preparing to administer medications to a client with a nasogastric (NG) tube is to check for tube placement. This step is crucial to ensure that the NG tube is correctly positioned in the stomach and not in the respiratory tract, reducing the risk of aspiration. Flushing the NG tube with 0.9% sodium chloride, administering the medications as a bolus, or dissolving the medications in sterile water should only be done after confirming the proper placement of the NG tube. Therefore, options B, C, and D are incorrect as they precede the essential step of verifying tube placement.
