Nursing Elites

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. When teaching a client with a new prescription for Simvastatin, which instruction should be included?

• A. Take this medication with food.
• B. Avoid drinking grapefruit juice.
• C. Take this medication in the morning.
• D. Increase your intake of potassium-rich foods.

Correct answer: B

Rationale: The correct instruction for a client with a new prescription for Simvastatin is to avoid drinking grapefruit juice. Grapefruit juice can inhibit the metabolism of Simvastatin, leading to increased blood levels of the drug and a higher risk of adverse effects such as muscle pain and liver damage. It is important to educate the client about this potential interaction to ensure the safe and effective use of the medication. Choices A, C, and D are incorrect because taking Simvastatin with food or in the morning and increasing potassium-rich foods intake are not specifically related to the safe use of Simvastatin. Avoiding grapefruit juice is crucial to prevent drug interactions.

3. A client has a prescription for Clonidine to treat hypertension. Which of the following instructions should the nurse include?

• A. Discontinue the medication if you experience dry mouth.
• B. Take the medication at the same time each day.
• C. Double the dose if you miss a dose.
• D. Avoid drinking orange juice while taking this medication.

Correct answer: B

Rationale: Correct Answer: Taking Clonidine at the same time each day is crucial to ensure consistent blood levels and effectively manage blood pressure. Consistency in timing helps optimize the medication's effectiveness in controlling hypertension.

4. A client with a UTI and a history of recurrent infections asks why the provider has not yet prescribed an antibiotic. The nurse should explain that the provider has to wait for the results of which of the following laboratory tests to identify which antibiotic to prescribe?

• A. Gram stain
• B. Culture
• C. Sensitivity
• D. Specific gravity

Correct answer: C

Rationale: In the case of a UTI, a sensitivity test is crucial as it identifies the most effective antibiotic to target the specific microorganism causing the infection. This test helps in prescribing the appropriate antibiotic for successful treatment and preventing antibiotic resistance. While a Gram stain and culture are important in diagnosing a UTI, the sensitivity test specifically determines the most suitable antibiotic. Specific gravity, on the other hand, is not related to identifying the appropriate antibiotic for a UTI.

5. A client is undergoing preparation for extensive colorectal surgery. Which of the following oral antibiotics should be administered to suppress normal flora in the GI tract?

• A. Kanamycin
• B. Gentamicin
• C. Neomycin
• D. Tobramycin

Correct answer: C

Rationale: The correct answer is C: Neomycin. Neomycin, an aminoglycoside antibiotic, is administered orally before GI surgery to eliminate the normal flora in the large intestine. This helps reduce the risk of postoperative infections by decreasing the bacterial load in the gut. Choices A, B, and D (Kanamycin, Gentamicin, Tobramycin) are not typically used to suppress normal flora in the GI tract before colorectal surgery.
