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. The nurse observes a client in a wheelchair with a vest restraint in place. What nursing intervention is most important for the nurse to implement?

• A. Assess the need for continued restraint
• B. Check the client for urinary incontinence
• C. Determine skin integrity under the vest
• D. Perform range-of-motion exercises on extremities

Correct answer: A

Rationale: The correct answer is to assess the need for continued restraint. This is the most important nursing intervention as it ensures the client's safety and autonomy. Checking for urinary incontinence (Choice B) may be important but is not the priority in this situation. Determining skin integrity under the vest (Choice C) is essential but not as crucial as assessing the need for continued restraint. Performing range-of-motion exercises (Choice D) is important for client mobility but not the priority when a restraint is in place.

3. The nurse is planning care for a 2-year-old child who is scheduled for an infusion of immune globulin for treatment of idiopathic thrombocytopenic purpura (ITP). Which nursing diagnosis has the highest priority for this child?

• A. Risk for infection
• B. Risk for injury
• C. Altered oral mucous membranes
• D. Risk for fluid volume deficit

Correct answer: A

Rationale: The correct answer is 'Risk for infection.' When caring for a child with ITP scheduled for immune globulin infusion, the highest priority is to prevent infection. This is crucial due to the risk of bleeding associated with ITP and the immunosuppression that can be caused by the condition and its treatment. The other options, such as 'Risk for injury,' 'Altered oral mucous membranes,' and 'Risk for fluid volume deficit,' are not as high a priority as preventing infection in this particular situation.

4. The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. International normalized ratio (INR)
• D. Activated partial thromboplastin time (aPTT)

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). While INR is commonly used to monitor the effectiveness of warfarin therapy, in the case of heparin therapy, the Partial Thromboplastin Time (PTT) is the preferred test. Choice A, Prothrombin Time (PT), measures the activity of the extrinsic pathway of coagulation and is not the best choice for monitoring heparin therapy. Choice D, Activated Partial Thromboplastin Time (aPTT), is similar to PTT and is used to monitor heparin therapy, but PTT is the more specific test. Therefore, monitoring PTT is crucial in determining the effectiveness and safety of heparin therapy.

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.
