Nursing Elites

1. A client is receiving continuous intravenous heparin for a deep vein thrombosis. Which laboratory result should the nurse monitor to ensure therapeutic heparin levels?

• A. International normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Hemoglobin
• D. Platelet count

Correct answer: B

Rationale: The activated partial thromboplastin time (aPTT) is the most accurate measure of heparin's therapeutic effect. Heparin increases the time it takes for blood to clot, and the aPTT helps determine whether the dose is within the desired range for anticoagulation therapy. Monitoring the INR, hemoglobin, or platelet count is not specific to assessing therapeutic heparin levels and may not reflect the anticoagulant effect of heparin.

2. The nurse is caring for a client with a suspected myocardial infarction (MI). Which laboratory test result is most indicative of a recent MI?

• A. Elevated troponin levels
• B. Increased white blood cell count
• C. Increased lactate dehydrogenase (LDH)
• D. Elevated C-reactive protein (CRP)

Correct answer: A

Rationale: Elevated troponin levels are the most specific and sensitive indicator of myocardial infarction. Troponin levels increase within hours of an MI and remain elevated for several days. White blood cell count, lactate dehydrogenase (LDH), and C-reactive protein (CRP) are not specific markers for MI. An increased white blood cell count may indicate inflammation or infection, increased LDH levels can be seen in various conditions like liver disease or muscle injury, and elevated CRP is a general marker of inflammation rather than specific to MI.

3. A client with a history of chronic kidney disease presents with increased swelling and shortness of breath. What is the nurse's priority action?

• A. Administer oxygen at 2 liters per nasal cannula.
• B. Administer a diuretic as prescribed.
• C. Monitor the client's vital signs.
• D. Reposition the client to improve lung expansion.

Correct answer: B

Rationale: The correct answer is to administer a diuretic as prescribed. In a client with chronic kidney disease experiencing increased swelling and shortness of breath, the priority action is to address fluid retention. Administering a diuretic helps reduce fluid overload, alleviate symptoms, and prevent complications associated with fluid buildup. Option A is not the priority in this situation as addressing fluid retention takes precedence over providing oxygen. While monitoring vital signs is important, it is secondary to addressing the underlying cause of symptoms. Repositioning the client may help with comfort but does not directly address the fluid overload seen in chronic kidney disease.

4. At 0600 while admitting a woman for a scheduled repeat cesarean section, the client tells the nurse that she drank a cup of coffee at 0400 because she wanted to avoid getting a headache. Which action should the nurse take first?

• A. Cancel the surgery
• B. Inform the anesthesia care provider
• C. Ask the client if she has had any other liquids
• D. Proceed with routine preparations

Correct answer: B

Rationale: Drinking liquids before surgery can increase the risk of aspiration during anesthesia. Therefore, the anesthesia care provider must be informed immediately to determine how to proceed, as this could delay or alter the surgical plan. Canceling the surgery without consulting the anesthesia care provider would be premature and could potentially lead to unnecessary actions. Asking the client if she has had any other liquids is important but not the first priority. Proceeding with routine preparations without addressing the potential issue of ingesting liquids before surgery could compromise the client's safety.

5. A client with diabetes mellitus is scheduled for surgery. What is the nurse's priority action when preparing this client for surgery?

• A. Ensure the client is NPO before surgery
• B. Monitor the client's blood glucose levels
• C. Administer the client's insulin as scheduled
• D. Teach the client about postoperative care

Correct answer: B

Rationale: The correct answer is B: Monitor the client's blood glucose levels. Clients with diabetes are at risk for perioperative complications related to blood glucose fluctuations. Monitoring blood glucose levels is crucial to maintaining proper management before, during, and after surgery. Option A is not the priority action as ensuring NPO status is a standard preoperative procedure for all clients. Option C could be important but is secondary to monitoring blood glucose levels. Option D is important but not the priority during the preoperative phase.
