Nursing Elites

1. A client in acute renal failure has a serum potassium of 7.5 mEq/L. Based on this finding, the nurse should anticipate implementing which action?

• A. Administer an IV of normal saline rapidly and NPH insulin subcutaneously.
• B. Administer a retention enema of Kayexalate.
• C. Add 40 mEq of KCL (potassium chloride) to the present IV solution.
• D. Administer a lidocaine bolus IV push.

Correct answer: B

Rationale: In acute renal failure with a high serum potassium level, the priority intervention is to lower potassium levels to prevent complications like cardiac arrhythmias. Administering a retention enema of Kayexalate is the correct action as it helps lower high potassium levels by exchanging sodium for potassium in the intestines. Options A, C, and D are incorrect. Administering normal saline rapidly and NPH insulin or adding more potassium to the IV solution can further increase potassium levels, worsening the condition. Lidocaine is not indicated for treating hyperkalemia.

2. A client with cirrhosis is taking lactulose (Cephulac). Which finding indicates that the lactulose is having the desired effect?

• A. Two to three soft bowel movements per day
• B. Increased serum ammonia levels
• C. Decreased white blood cell count
• D. Soft, formed stool twice a day

Correct answer: A

Rationale: The correct answer is A: 'Two to three soft bowel movements per day.' Lactulose is prescribed to produce soft, regular bowel movements to reduce ammonia levels in clients with cirrhosis. This helps in preventing hepatic encephalopathy. Option B is incorrect because increased serum ammonia levels would indicate that lactulose is not effectively reducing ammonia levels. Option C is incorrect because lactulose does not directly affect white blood cell counts. Option D is incorrect because soft, formed stools twice a day may not be frequent enough to effectively reduce ammonia levels in clients with cirrhosis.

3. The nurse-manager of a perinatal unit is notified that one client from the medical-surgical unit needs to be transferred to make room for new admissions. Which client should the nurse recommend for transfer to the antepartal unit?

• A. A 45-year-old with chronic hepatitis B.
• B. A 35-year-old with lupus erythematosus
• C. A 19-year-old diagnosed with rubella
• D. A 25-year-old with herpes lesions of the vulva

Correct answer: B

Rationale: The correct answer is B because a client with lupus erythematosus can be safely transferred to the antepartal unit as this condition does not pose a significant risk to other patients or staff. Choices A, C, and D should not be recommended for transfer to the antepartal unit due to the potential risks they may pose to pregnant women and their unborn babies. Chronic hepatitis B, rubella, and herpes lesions of the vulva can be contagious and harmful in the perinatal setting.

4. The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?

• A. Blood glucose of 140 mg/dL
• B. White blood cell count of 8000/mm³
• C. Serum potassium of 3.8 mEq/L
• D. Serum calcium of 7.8 mg/dL

Correct answer: D

Rationale: The correct answer is D. A serum calcium level of 7.8 mg/dL requires immediate intervention due to the risk of hypocalcemia. Hypocalcemia can lead to serious complications such as tetany, seizures, and cardiac arrhythmias. The other laboratory findings are within normal limits or slightly elevated, which do not pose an immediate threat to the client's health in this scenario.

5. The nurse is performing an admission assessment of an older client who has difficulty swallowing and has a history of aspiration pneumonia. Which action should the nurse implement first?

• A. Obtain a speech therapy consult
• B. Elevate the head of the bed
• C. Check the client's lung sounds
• D. Implement aspiration precautions

Correct answer: B

Rationale: The correct action for the nurse to implement first is to elevate the head of the bed. Elevating the head of the bed helps prevent aspiration in clients with swallowing difficulties by reducing the risk of food or fluids entering the airway. While obtaining a speech therapy consult (Choice A) is important, the immediate priority is to ensure the client's safety by positioning them properly. Checking the client's lung sounds (Choice C) and implementing aspiration precautions (Choice D) are also essential steps but should follow the immediate intervention of elevating the head of the bed to prevent aspiration.
