Nursing Elites

1. A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?

• A. Serum creatine kinase (CK)
• B. Serum troponin
• C. Serum myoglobin
• D. C-reactive protein (CRP)

Correct answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

2. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which intervention should the nurse implement first?

• A. Administer intravenous calcium gluconate.
• B. Administer intravenous insulin and glucose.
• C. Administer intravenous sodium bicarbonate.
• D. Administer a loop diuretic as prescribed.

Correct answer: B

Rationale: The correct answer is B: Administer intravenous insulin and glucose. In the presence of hyperkalemia, the priority intervention is to shift potassium back into the cells to lower serum levels. Insulin, in combination with glucose, helps drive potassium intracellularly. Administering calcium gluconate (choice A) is used to stabilize myocardial cell membranes but does not address the underlying cause of hyperkalemia. Administering sodium bicarbonate (choice C) is not the initial treatment for hyperkalemia. Loop diuretics (choice D) may be used later to enhance potassium excretion but are not the primary intervention for acute hyperkalemia.

3. When finding a client sitting on the floor, the nurse calls for help from the unlicensed assistive personnel (UAP). Which task should the nurse ask the UAP to do?

• A. Check for any abrasions or bruises.
• B. Help the client to stand.
• C. Get a blood pressure cuff.
• D. Report the fall to the nurse-manager.

Correct answer: C

Rationale: The correct task for the nurse to ask the unlicensed assistive personnel (UAP) to do in this situation is to "Get a blood pressure cuff." This is important because assessing the client's vital signs, including blood pressure, is crucial after a fall to ensure there are no underlying issues like hypotension. Choices A and B may be important tasks for the nurse to perform as part of the assessment and care of the client. However, in this scenario, the immediate concern should be to check the client's blood pressure. Choice D is not the most urgent task at this time, as assessing the client's condition takes precedence.

4. The nurse is reinforcing home care instructions with a client who is being discharged following a transurethral resection of the prostate (TURP). Which intervention is most important for the nurse to include in the client teaching?

• A. Avoid strenuous activity for 6 weeks.
• B. Report fresh blood in the urine.
• C. Take acetaminophen for a fever over 101°F.
• D. Consume 6 to 8 glasses of water daily.

Correct answer: B

Rationale: Reporting fresh blood in the urine is crucial as it may indicate postoperative complications requiring immediate attention. This symptom can be a sign of bleeding, infection, or other issues that need prompt medical evaluation. Avoiding strenuous activity for 6 weeks is important but not as urgent as reporting fresh blood. Taking acetaminophen for a fever over 101°F is relevant but addressing fresh blood in the urine takes precedence. Consuming an adequate amount of water daily is beneficial but not as critical as recognizing and reporting signs of potential complications.

5. In caring for a client receiving the aminoglycoside antibiotic gentamicin, what diagnostic test should the nurse prioritize monitoring?

• A. Urinalysis
• B. Serum creatinine
• C. Serum osmolarity
• D. Liver enzymes

Correct answer: B

Rationale: The correct answer is B: Serum creatinine. Aminoglycosides, such as gentamicin, are known to cause nephrotoxicity, which can lead to kidney damage. Monitoring serum creatinine levels is crucial in assessing renal function and detecting any potential kidney problems early. Choices A, C, and D are incorrect because urinalysis primarily assesses urine composition, serum osmolarity measures the concentration of solutes in the blood, and liver enzymes are not directly impacted by aminoglycoside antibiotics like gentamicin.
