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 acute pancreatitis is admitted with severe abdominal pain. Which assessment finding requires immediate intervention?

• A. Severe abdominal distention
• B. Decreased urine output
• C. Decreased bowel sounds
• D. Increased heart rate

Correct answer: A

Rationale: Severe abdominal distention is a sign of worsening pancreatitis and can indicate complications like bowel obstruction or fluid accumulation. Immediate intervention is necessary to prevent further deterioration. Decreased urine output (Choice B) could indicate renal impairment, decreased bowel sounds (Choice C) are expected in pancreatitis due to paralytic ileus, and an increased heart rate (Choice D) is a common response to pain or stress in acute pancreatitis but may not require immediate intervention unless it is extremely high or persistent.

3. A client with heart failure is receiving digoxin (Lanoxin) and furosemide (Lasix). Which assessment finding requires immediate intervention?

• A. Heart rate of 60 beats per minute
• B. Apical pulse of 58 beats per minute
• C. Presence of a new murmur
• D. Blood pressure of 100/60 mmHg

Correct answer: C

Rationale: The correct answer is C. The presence of a new murmur in a client with heart failure receiving digoxin and furosemide is concerning as it may indicate valvular problems or other complications that require immediate intervention. A heart rate of 60 beats per minute and an apical pulse of 58 beats per minute are within normal limits for a client with heart failure on these medications. A blood pressure of 100/60 mmHg, while slightly low, may be expected due to the diuretic effect of furosemide and may not require immediate intervention unless the client is symptomatic.

4. While removing staples from a male client's postoperative wound site, the nurse observes that the client's eyes are closed and his face and hands are clenched. The client states, 'I just hate having staples removed.' After acknowledging the client's anxiety, what action should the nurse implement?

• A. Attempt to distract the client with general conversation
• B. Administer a pain medication
• C. Continue with the procedure while reassuring the client
• D. Stop the procedure and notify the healthcare provider

Correct answer: A

Rationale: In this situation, the nurse should attempt to distract the client with general conversation. Distracting the client can help reduce anxiety and make the procedure less stressful. Administering pain medication (choice B) is not appropriate as the client's discomfort is related to anxiety, not physical pain. Continuing with the procedure while reassuring the client (choice C) may not address the client's anxiety effectively. Stopping the procedure and notifying the healthcare provider (choice D) is not necessary at this point since the client's anxiety can be managed by attempting to distract him.

5. A client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which laboratory value should the nurse report to the healthcare provider immediately?

• A. Serum potassium of 5.5 mEq/L
• B. Serum calcium of 8 mg/dL
• C. Serum creatinine of 2.0 mg/dL
• D. White blood cell count of 10,000/mm³

Correct answer: A

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to serious cardiac arrhythmias, especially during hemodialysis. Serum calcium, serum creatinine, and white blood cell count, while important, do not pose immediate life-threatening risks like hyperkalemia.
