Nursing Elites

1. A client is being discharged with a new prescription for Lisinopril. Which of the following instructions should be included by the healthcare provider?

• A. Avoid salt substitutes.
• B. Take this medication at bedtime.
• C. Increase your intake of potassium-rich foods.
• D. Take this medication with food.

Correct answer: A

Rationale: The correct answer is to instruct the client to avoid salt substitutes. Lisinopril, an ACE inhibitor, can lead to hyperkalemia, so it's essential to avoid salt substitutes that may contain potassium which can further elevate potassium levels. Choice B is incorrect because Lisinopril is typically taken once daily in the morning, not at bedtime. Choice C is incorrect as increasing potassium intake can exacerbate hyperkalemia when taking Lisinopril. Choice D is incorrect as Lisinopril is usually taken on an empty stomach, not with food.

2. A client prescribed Warfarin is receiving discharge instructions from a nurse. Which of the following herbal supplements should the nurse instruct the client to avoid?

• A. St. John's wort
• B. Echinacea
• C. Garlic
• D. Ginseng

Correct answer: A

Rationale: St. John's wort can reduce the effectiveness of Warfarin by interacting with its metabolism pathways, potentially leading to decreased anticoagulant effects. Therefore, clients on Warfarin therapy should avoid St. John's wort. While echinacea, garlic, and ginseng are also herbal supplements that can interact with Warfarin, St. John's wort is particularly known for its significant impact on Warfarin metabolism. Echinacea may increase the risk of bleeding when taken with Warfarin, garlic may potentiate the anticoagulant effects of Warfarin, and ginseng may also increase the risk of bleeding. However, St. John's wort is the most crucial to avoid due to its significant impact on Warfarin metabolism.

3. A client is taking metformin for type 2 diabetes. Which of the following findings should indicate to the nurse that the medication is effective?

• A. Increased urine output
• B. Decreased fasting blood glucose
• C. Decreased hemoglobin A1C
• D. Decreased polyuria

Correct answer: C

Rationale: A decrease in hemoglobin A1C is a more specific indicator of metformin's effectiveness in controlling blood glucose levels over a longer period compared to fasting blood glucose levels. Hemoglobin A1C reflects average blood sugar levels over the past 2-3 months, providing a more comprehensive view of glycemic control. Increased urine output (choice A) is not a direct indicator of metformin's effectiveness and can be influenced by various factors. Decreased fasting blood glucose (choice B) can fluctuate due to various reasons and may not provide a reliable long-term assessment of metformin's efficacy. Decreased polyuria (choice D) refers to a symptom rather than a direct measure of metformin's effectiveness in managing diabetes.

4. A client with peptic ulcer disease is prescribed sucralfate. Which of the following instructions should the nurse include?

• A. Take sucralfate with meals.
• B. Take sucralfate 1 hr before meals.
• C. Take sucralfate with antacids.
• D. Take sucralfate 2 hours after meals.

Correct answer: B

Rationale: The correct instruction for taking sucralfate is 1 hour before meals. This timing allows sucralfate to effectively coat the stomach lining and provide a protective barrier against gastric acid, helping to prevent ulcers.

5. A client is receiving heparin therapy. Which laboratory value should be monitored by the nurse to evaluate the effectiveness of the therapy?

• A. PT
• B. aPTT
• C. INR
• D. Platelet count

Correct answer: B

Rationale: The activated partial thromboplastin time (aPTT) is specifically used to monitor the effectiveness of heparin therapy. It should be maintained at 1.5 to 2 times the normal level. Monitoring aPTT helps ensure that the therapeutic range of heparin is achieved to prevent clot formation while minimizing the risk of bleeding complications. Choice A (PT) is incorrect as it is used to monitor warfarin therapy, not heparin. Choice C (INR) is also incorrect as it is primarily used to monitor warfarin therapy. Choice D (Platelet count) is not directly related to monitoring the effectiveness of heparin therapy.
