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 with a history of type 2 diabetes is admitted with hyperglycemia. What is the nurse's priority action?

• A. Administer a dose of insulin as prescribed.
• B. Check the client's blood glucose level.
• C. Administer a fluid bolus to improve hydration.
• D. Monitor the client's intake and output closely.

Correct answer: B

Rationale: The correct answer is to check the client's blood glucose level. This is the priority action when dealing with a client admitted with hyperglycemia. Checking the blood glucose level helps determine the severity of hyperglycemia and guides further treatment. Administering insulin or fluids or monitoring intake and output are important interventions but should come after assessing the blood glucose level to inform the most appropriate course of action.

3. A client with osteoarthritis is prescribed acetaminophen. What is the most important teaching the nurse should provide?

• A. Take the medication with food to improve absorption.
• B. Avoid taking other pain medications to prevent liver damage.
• C. Take acetaminophen on an empty stomach to prevent stomach upset.
• D. Monitor liver function tests regularly to detect any liver damage.

Correct answer: B

Rationale: The correct answer is B. Acetaminophen can cause liver damage if taken in excessive amounts or in combination with other medications containing acetaminophen. Clients should be advised to avoid other pain medications to prevent liver toxicity. Choice A is incorrect because acetaminophen is usually taken with or without food, not specifically on an empty stomach. Choice C is incorrect because taking acetaminophen with food can help prevent stomach upset. Choice D is incorrect because while monitoring liver function tests is important for long-term acetaminophen use, the most crucial teaching is to avoid other pain medications to prevent liver damage.

4. A client with adrenal insufficiency is admitted to the ICU with acute adrenal crisis. The client's vital signs include heart rate 138 bpm and BP 80/60. What is the nurse's first intervention?

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

Correct answer: B

Rationale: The correct first intervention for a client with adrenal crisis and hypotension is to administer an IV fluid bolus. In adrenal crisis, the body is deficient in cortisol, leading to hypotension. Fluid resuscitation helps stabilize the blood pressure. Obtaining an analgesic prescription (Choice A) is not the priority in this situation. Administering a PRN antipyretic (Choice C) is not indicated as the client's vital signs do not suggest fever. Covering the client with a cooling blanket (Choice D) is not appropriate for addressing hypotension in adrenal crisis.

5. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin. Which laboratory value should the nurse monitor to assess the therapeutic effect of this medication?

• A. Platelet count
• B. Prothrombin time (PT)
• C. White blood cell count
• D. Hemoglobin level

Correct answer: B

Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.
