Nursing Elites

1. 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.

2. When caring for a laboring client whose contractions are occurring every 2-3 minutes, the nurse should document that the pump is infusing how many ml/hour?

• A. 5
• B. 10
• C. 15
• D. 20

Correct answer: A

Rationale: The correct calculation for infusion based on the given data is 5 ml/hr. To calculate the infusion rate per hour, you need to determine the number of contractions per hour. If contractions are occurring every 2-3 minutes, this would mean approximately 20-30 contractions per hour. Therefore, if the pump is infusing 5 ml per contraction, the total infusion rate per hour would be 5 ml x 20 contractions = 100 ml/hr. This makes choice A the correct answer. Choices B, C, and D are incorrect as they do not align with the calculation based on the given data.

3. Which assessment finding should indicate to the nurse that a client with arterial hypertension is experiencing a cardiac complication?

• A. Complaints of an occipital headache
• B. A palpable dorsal pedis pulse bilaterally
• C. Complaints of shortness of breath on exertion
• D. A blood pressure of 160/90

Correct answer: C

Rationale: The correct answer is C, complaints of shortness of breath on exertion. This symptom is indicative of heart failure, a common cardiac complication of arterial hypertension. Shortness of breath on exertion is often due to the heart's inability to pump effectively, leading to fluid buildup in the lungs. Choices A, B, and D are incorrect because complaints of an occipital headache, a palpable dorsal pedis pulse bilaterally, and a blood pressure of 160/90 do not specifically indicate a cardiac complication in a client with arterial hypertension.

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. 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.
