1. A healthcare professional is reviewing the medication list of a client who has a new prescription for Digoxin to treat heart failure. Which of the following medications places the client at risk for Digoxin toxicity?

• A. Spironolactone
• B. Calcium channel blockers
• C. Loop diuretics
• D. ACE inhibitors

Correct answer: C

Rationale: Loop diuretics, such as Furosemide, can increase the risk of Digoxin toxicity by causing hypokalemia. Hypokalemia enhances the toxic effects of Digoxin on the heart, leading to an increased risk of Digoxin toxicity. Spironolactone (Choice A) is less likely to cause hypokalemia and does not significantly increase the risk of Digoxin toxicity. Calcium channel blockers (Choice B) and ACE inhibitors (Choice D) do not directly increase the risk of Digoxin toxicity through hypokalemia; therefore, they are not the medications that place the client at risk for Digoxin toxicity.

2. Phenytoin is an antiarrhythmic and anticonvulsant that has an unlabeled use for:

• A. Headaches
• B. Cold remedy
• C. Neuropathic pain
• D. Antianxiety

Correct answer: C

Rationale: Phenytoin, an antiarrhythmic and anticonvulsant medication, is also used off-label for treating neuropathic pain. While its primary indications are for managing heart rhythm disorders and seizures, it has shown efficacy in managing neuropathic pain, expanding its clinical utility. Choices A, B, and D are incorrect as phenytoin is not commonly used for headaches, cold remedies, or antianxiety purposes.

3. A client is taking lisinopril. Which of the following outcomes indicates a therapeutic effect of the medication?

• A. Decreased blood pressure
• B. Increase in HDL cholesterol
• C. Prevention of bipolar manic episodes
• D. Improved sexual function

Correct answer: A

Rationale: The therapeutic effect of lisinopril, an ACE inhibitor, is indicated by a decrease in blood pressure. Lisinopril works by relaxing blood vessels, leading to a reduction in blood pressure. Monitoring and achieving a decrease in blood pressure is a key outcome when managing hypertension with lisinopril. Choices B, C, and D are incorrect because lisinopril is not intended to increase HDL cholesterol, prevent bipolar manic episodes, or improve sexual function. Therefore, the correct outcome indicating the therapeutic effect of lisinopril is a decrease in blood pressure.

4. A client is receiving treatment with methotrexate. Which of the following supplements should the nurse instruct the client to take?

• A. Folic acid
• B. Vitamin D
• C. Calcium
• D. Iron

Correct answer: A

Rationale: The nurse should instruct the client to take folic acid when receiving treatment with methotrexate to reduce the risk of methotrexate toxicity. Methotrexate acts as a folic acid antagonist, leading to folic acid deficiency, which can be counteracted by supplementing with folic acid. Vitamin D, calcium, and iron are not specifically recommended to counteract methotrexate effects and do not play a significant role in mitigating methotrexate toxicity.

5. A client has a new prescription for Furosemide. What instruction should be included by the nurse during discharge?

• A. Take the medication at bedtime.
• B. Increase intake of foods high in potassium.
• C. Avoid sun exposure.
• D. Limit fluid intake.

Correct answer: B

Rationale: The correct answer is to instruct the client to increase intake of foods high in potassium. Furosemide, a loop diuretic, can lead to potassium depletion. Increasing the intake of foods rich in potassium can help prevent hypokalemia, a potential side effect of Furosemide. Choice A is incorrect as Furosemide is usually recommended to be taken in the morning to avoid disrupting sleep with frequent urination. Choice C is irrelevant to the medication. Choice D is also incorrect as Furosemide is a diuretic and may require increased, not limited, fluid intake to prevent dehydration.
