Nursing Elites

1. An older client with a long history of coronary artery disease, HTN, and HF arrives in the ED in respiratory distress. The healthcare provider prescribes furosemide IV. Which therapeutic response to furosemide should the nurse expect in the client with acute HF?

• A. Decreased heart rate
• B. Improved blood pressure
• C. Increased urine output
• D. Reduced preload

Correct answer: D

Rationale: The correct answer is D: Reduced preload. Furosemide is a diuretic that reduces fluid overload in heart failure, which lowers the preload (the volume of blood in the ventricles before contraction). By reducing this volume, furosemide improves symptoms of heart failure. While furosemide may lead to increased urine output and lower blood pressure, these effects are secondary to the reduction in preload. Decreased heart rate is not a direct effect of furosemide in heart failure.

2. A client with hypertension is prescribed hydrochlorothiazide. What teaching should the nurse provide?

• A. Take the medication in the morning to avoid frequent urination at night.
• B. Increase fluid intake to prevent dehydration.
• C. Avoid potassium-rich foods, such as bananas and oranges.
• D. Monitor the client’s potassium levels weekly.

Correct answer: B

Rationale: The correct teaching for a client prescribed hydrochlorothiazide is to increase fluid intake to prevent dehydration. Hydrochlorothiazide is a diuretic that can lead to fluid loss and electrolyte imbalances, so adequate fluid intake is crucial. Choice A is incorrect because hydrochlorothiazide is typically taken in the morning to avoid nighttime urination. Choice C is incorrect as potassium-rich foods should not be avoided but monitored, as hydrochlorothiazide can cause potassium loss. Choice D is incorrect as potassium levels should be monitored regularly, but not necessarily weekly, unless indicated by the healthcare provider.

3. A client with chronic renal failure has a potassium level of 6.5 mEq/L. What is the nurse's priority action?

• A. Administer a potassium supplement.
• B. Notify the healthcare provider immediately.
• C. Administer calcium gluconate.
• D. Restrict the client's potassium intake.

Correct answer: B

Rationale: A potassium level of 6.5 mEq/L indicates hyperkalemia, which can lead to life-threatening arrhythmias. The correct priority action for the nurse is to notify the healthcare provider immediately. Hyperkalemia requires prompt intervention to lower potassium levels and prevent complications. Administering a potassium supplement (Choice A) would worsen the condition. Administering calcium gluconate (Choice C) is a treatment option but is not the nurse's priority action. Restricting the client's potassium intake (Choice D) may be necessary but is not the immediate priority when facing a critical potassium level.

4. The nurse is preparing an older adult for discharge following cataract extraction. What is the most important instruction?

• A. Avoid straining, bending, or lifting heavy objects.
• B. Limit exposure to sunlight for the first 2 weeks.
• C. Use direct lighting when reading for 6 weeks.
• D. Irrigate the conjunctiva with saline before applying ointment.

Correct answer: A

Rationale: The most important instruction for a patient following cataract extraction is to avoid straining, bending, or lifting heavy objects. These activities can increase intraocular pressure and potentially lead to complications such as bleeding or dislocation of the intraocular lens. Choices B, C, and D are not as critical in the immediate post-operative period. Limiting sunlight exposure and using direct lighting when reading are important but not as crucial as avoiding activities that can increase intraocular pressure. Irrigating the conjunctiva with saline before applying ointment is not a standard post-cataract surgery instruction.

5. An older adult client is admitted with pneumonia and prescribed penicillin G potassium. Which factor increases the risk of an adverse reaction?

• A. Sputum culture showing Streptococcus pneumoniae.
• B. Previous treatment with penicillin.
• C. Daily use of spironolactone for hypertension.
• D. Documented allergy to sulfa drugs.

Correct answer: C

Rationale: The correct answer is C. Daily use of spironolactone for hypertension can increase the risk of hyperkalemia and interact with penicillin, leading to adverse reactions. Choice A is incorrect because the sputum culture showing Streptococcus pneumoniae is an expected finding in a patient with pneumonia and does not increase the risk of an adverse reaction to penicillin. Choice B is incorrect as previous treatment with penicillin does not necessarily increase the risk of an adverse reaction to penicillin if there was no history of allergic reactions. Choice D is also incorrect as a documented allergy to sulfa drugs does not directly increase the risk of an adverse reaction to penicillin.
