Nursing Elites

1. 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.

2. 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.

3. A client with adrenal crisis has a temperature of 102°F, heart rate of 138 bpm, and blood pressure of 80/60 mmHg. Which action should the nurse implement first?

• A. Obtain an analgesic prescription.
• B. Infuse intravenous fluid bolus.
• C. Administer PRN oral antipyretic.
• D. Cover the client with a cooling blanket.

Correct answer: B

Rationale: In a client with adrenal crisis presenting with a high temperature, tachycardia, and hypotension, the priority action for the nurse to implement first is to infuse an intravenous fluid bolus. This intervention aims to address the hypotension by increasing the circulating volume and improving perfusion. Obtaining an analgesic prescription (Choice A) is not the priority in this situation. Administering an oral antipyretic (Choice C) may help reduce the fever but does not address the primary issue of hypotension. Covering the client with a cooling blanket (Choice D) may help with temperature control but does not address the hemodynamic instability caused by the adrenal crisis.

4. The mother of a 2-day-old infant girl expresses concern about a 'flea bite' type rash on her daughter's body. The nurse identifies a pink papular rash with vesicles superimposed over the thorax, back, buttocks, and abdomen. Which explanation should the nurse offer?

• A. We need to monitor the rash for signs of worsening or fever
• B. Your baby may have an allergic reaction to laundry detergent
• C. This is a common newborn rash that will resolve after several days
• D. This is likely a bacterial infection requiring antibiotics

Correct answer: C

Rationale: The rash described is typical of erythema toxicum neonatorum, a common and benign newborn rash that resolves on its own within a few days. No treatment is necessary, and the nurse should reassure the mother. Choice A is incorrect as the rash is self-limiting and does not require monitoring for worsening signs or fever. Choice B is incorrect as erythema toxicum neonatorum is not caused by an allergic reaction to laundry detergent. Choice D is incorrect as this rash is not indicative of a bacterial infection that requires antibiotics.

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.
