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. Which instruction should the nurse provide to an elderly client who is taking an ACE inhibitor and a calcium channel blocker?

• A. Wear long-sleeved clothing when outdoors
• B. Report the onset of sore throat
• C. Eat plenty of potassium-rich food
• D. Change the position slowly

Correct answer: D

Rationale: The correct instruction for an elderly client taking both an ACE inhibitor and a calcium channel blocker is to change positions slowly. Both medications can lead to orthostatic hypotension, a sudden drop in blood pressure when changing positions, which can increase the risk of falls. Instructing the client to change positions slowly helps prevent falls. Wearing long-sleeved clothing when outdoors does not directly relate to the medication combination. Reporting the onset of a sore throat is important for monitoring potential side effects but is not specific to these medications. While potassium levels should be monitored with ACE inhibitors, eating plenty of potassium-rich foods without guidance can lead to hyperkalemia, a potential side effect of ACE inhibitors.

3. The nurse is caring for a client who is receiving a continuous intravenous infusion of heparin. Which laboratory value should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Partial thromboplastin time (PTT)
• D. Hemoglobin level

Correct answer: C

Rationale: The correct answer is C. Partial thromboplastin time (PTT) is the laboratory value that should be monitored to evaluate the effectiveness of heparin therapy. PTT reflects the intrinsic pathway of coagulation and is specifically sensitive to heparin's anticoagulant effects. Monitoring the PTT helps ensure that the client is within the therapeutic range to prevent clot formation without increasing the risk of bleeding. Choices A, B, and D are incorrect because while they are important laboratory values in other contexts, they are not specifically used to monitor the effectiveness of heparin therapy.

4. The nurse is caring for a client who is receiving morphine sulfate via a patient-controlled analgesia (PCA) pump. Which action is most important for the nurse to implement?

• A. Monitor the client's respiratory status
• B. Teach the client how to use the PCA pump
• C. Evaluate the client's pain level
• D. Assess the client's pain level

Correct answer: A

Rationale: The correct answer is to monitor the client's respiratory status. When administering opioids like morphine sulfate via a PCA pump, it is crucial to closely monitor the client's respiratory status to detect signs of respiratory depression early. This is important for ensuring the client's safety while receiving pain management. Choices B, C, and D are incorrect because while teaching the client to use the PCA pump and assessing or evaluating their pain level are essential aspects of care, monitoring respiratory status takes precedence due to the potential risks associated with opioid use.

5. When obtaining a urine specimen from a female infant, which intervention should the nurse implement?

• A. Place the wet diaper in a biohazard specimen bag
• B. Obtain the urine sample using a straight size 4 French catheter
• C. Collect the urinary stream in mid-air when the infant cries
• D. Secure the pediatric urine collector bag to the perineum

Correct answer: D

Rationale: When obtaining a urine specimen from a female infant, securing the pediatric urine collector bag to the perineum is the most appropriate intervention. This method allows for non-invasive collection of urine without causing discomfort or distress to the infant. Placing the wet diaper in a biohazard specimen bag (Choice A) is incorrect as it does not involve collecting a fresh urine sample. Using a catheter (Choice B) is invasive and not typically necessary for routine urine specimen collection from infants. Collecting the urinary stream in mid-air when the infant cries (Choice C) is not a reliable or hygienic method of obtaining a urine specimen.
