Nursing Elites

1. 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.

2. A client with a history of heart failure is admitted to the hospital with worsening dyspnea. The nurse notes that the client has a productive cough with pink, frothy sputum. What action should the nurse take first?

• A. Administer oxygen
• B. Perform chest physiotherapy
• C. Elevate the head of the bed
• D. Obtain a sputum specimen

Correct answer: A

Rationale: In a client with heart failure presenting with worsening dyspnea and pink, frothy sputum (indicating pulmonary edema), the priority action for the nurse is to administer oxygen. Oxygen therapy helps improve oxygenation and alleviate dyspnea by increasing the oxygen supply to the lungs. Performing chest physiotherapy, elevating the head of the bed, or obtaining a sputum specimen are not the initial actions indicated in this situation and may delay addressing the client's immediate need for improved oxygenation.

3. 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.

4. A 7-year-old with cystic fibrosis (CF) has received instructions about home care. Which statement made by the child's mother indicates that further teaching is needed?

• A. My child should not have a cough at all times
• B. He needs to take pancreatic enzymes with meals and snacks
• C. He needs to use a bronchodilator every day
• D. His dietary intake needs to be high in protein and calories

Correct answer: A

Rationale: The correct answer is A. A cough at all times is not normal in a child with cystic fibrosis (CF) and indicates the need for further teaching on CF management. Choices B, C, and D are correct statements in managing CF: taking pancreatic enzymes with meals and snacks, using a bronchodilator daily, and maintaining a high-protein and high-calorie dietary intake are all appropriate for a child with CF.

5. The nurse is assessing a client who is 2 days post-op following abdominal surgery. The client reports feeling something 'give way' in the incision site and there is a small amount of bowel protruding from the wound. What action should the nurse take first?

• A. Apply a sterile saline dressing to the wound
• B. Notify the healthcare provider
• C. Administer pain medication
• D. Cover the wound with an abdominal binder

Correct answer: A

Rationale: In this scenario, the nurse should first apply a sterile saline dressing to the wound. This action helps prevent infection and keeps the wound moist, which is crucial in promoting healing. Option B, notifying the healthcare provider, is important but should come after providing immediate wound care. Option C, administering pain medication, is not the priority when there is a small amount of bowel protruding from the wound. Option D, covering the wound with an abdominal binder, is not appropriate for this situation as it does not address the protruding bowel and potential risk for infection.
