Nursing Elites

1. A client with a history of myocardial infarction is admitted with chest pain. Which laboratory value should the nurse monitor closely?

• A. White blood cell count
• B. Serum creatinine
• C. Troponin level
• D. Hemoglobin level

Correct answer: C

Rationale: The correct answer is C: Troponin level. Troponin levels should be closely monitored in a client with chest pain and a history of myocardial infarction to assess for ongoing myocardial injury. Troponin is a specific marker for myocardial damage. Monitoring white blood cell count (choice A) is not directly related to myocardial infarction. Serum creatinine (choice B) is more indicative of renal function rather than cardiac status. Hemoglobin level (choice D) is important but does not directly reflect ongoing myocardial injury.

2. The charge nurse of the critical care unit informed at the beginning of the shift that a less than optimal number of registered nurses would be working that shift. In planning assignments, which client should receive the most care hours by a registered nurse?

• A. A 34-year-old admitted today after an emergency appendectomy who has a peripheral intravenous catheter and a Foley catheter.
• B. A 48-year-old marathon runner with a central venous catheter experiencing nausea and vomiting due to electrolyte disturbance following a race.
• C. A 63-year-old chain smoker with chronic bronchitis receiving oxygen via nasal cannula and a saline-locked peripheral intravenous catheter.
• D. An 82-year-old client with Alzheimer's disease and a newly fractured femur with a Foley catheter and soft wrist restraints applied.

Correct answer: D

Rationale: The 82-year-old client with Alzheimer's disease and a newly fractured femur should receive the most care hours by a registered nurse because they are at the highest risk for injury and complications. The client's age, diagnosis of Alzheimer's disease, and the presence of a newly fractured femur along with the Foley catheter and wrist restraints indicate a need for close monitoring and care. Choice A is less critical as the client is stable post-appendectomy. Choice B, though experiencing symptoms, is not at the same level of risk as the client in Choice D. Choice C, while requiring oxygen support, does not have the same level of acuity and complexity as the client in Choice D.

3. A male client reports the onset of numbness and tingling in his fingers and around his mouth. Which lab test is important for the nurse to review before contacting the healthcare provider?

• A. Capillary glucose
• B. Urine specific gravity
• C. Serum calcium
• D. White blood cell count

Correct answer: C

Rationale: The correct answer is C: Serum calcium. Numbness and tingling in the fingers and around the mouth are indicative of hypocalcemia. Serum calcium levels should be reviewed as they play a crucial role in diagnosing and managing hypocalcemia. Option A, capillary glucose, is not relevant to the symptoms described. Option B, urine specific gravity, is not typically used to assess numbness and tingling. Option D, white blood cell count, is unrelated to the symptoms presented by the client.

4. A client with heart failure is prescribed furosemide (Lasix). Which assessment finding should the nurse report to the healthcare provider immediately?

• A. Heart rate of 60 beats per minute
• B. Blood pressure of 100/60 mmHg
• C. Presence of a new murmur
• D. Crackles in the lungs

Correct answer: D

Rationale: The correct answer is D: Crackles in the lungs. Crackles indicate fluid overload in the lungs, a critical sign in a client with heart failure. This finding suggests that the furosemide may not be effectively managing the fluid balance, and immediate intervention is required. Choices A, B, and C are not immediate concerns in this scenario. A heart rate of 60 beats per minute, a blood pressure of 100/60 mmHg, and the presence of a new murmur are findings that may require monitoring or intervention but are not as urgent as crackles in the lungs in a client with heart failure.

5. A client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which laboratory value should be closely monitored before the procedure?

• A. Serum creatinine of 2.0 mg/dl
• B. Serum potassium of 5.5 mEq/L
• C. Serum calcium of 8.0 mg/dl
• D. Hemoglobin of 12 g/dl

Correct answer: B

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, which can lead to serious cardiac complications. Hyperkalemia can be exacerbated during hemodialysis, making it crucial to closely monitor serum potassium levels before the procedure. Monitoring serum creatinine, serum calcium, or hemoglobin levels is important in managing ESRD but is not the immediate focus before hemodialysis. Therefore, option B is the correct choice.
