Nursing Elites

1. A client with a history of chronic kidney disease (CKD) is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?

• A. Serum creatinine
• B. Blood urea nitrogen (BUN)
• C. Serum potassium
• D. Serum glucose

Correct answer: A

Rationale: The correct answer is A: Serum creatinine. Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in patients with CKD because contrast agents can potentially worsen kidney function and lead to contrast-induced nephropathy. Monitoring serum creatinine helps assess kidney function and determine the risk of complications. Choices B, C, and D are less relevant in this scenario. Blood urea nitrogen (BUN) is another marker of kidney function, but serum creatinine is a more specific indicator. Serum potassium levels are important in assessing electrolyte balance but are not directly related to the risk of contrast-induced nephropathy. Serum glucose levels are not typically a primary concern before a CT scan with contrast in a patient with CKD.

2. An older female client tells the nurse that her muscles have gradually been getting weaker over time. What is the best initial response by the nurse?

• A. Explain that this is an expected occurrence with aging.
• B. Observe the lower extremities for signs of muscle atrophy.
• C. Review the medical record for recent diagnostic test results.
• D. Ask the client to describe the changes that have occurred.

Correct answer: D

Rationale: The best initial response by the nurse should be to ask the client to describe the changes that have occurred. This open-ended question allows the nurse to gather valuable information directly from the client, aiding in assessing the situation accurately and formulating an appropriate care plan. Choice A is incorrect as assuming muscle weakness is an expected occurrence with aging without further assessment may overlook potential underlying issues. Choice B is premature as it jumps straight to physical examination without first gathering subjective data. Choice C is unnecessary at this point as reviewing diagnostic test results should come after initial assessment and data collection from the client.

3. 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.

4. A client with heart failure is prescribed furosemide (Lasix). Which assessment finding requires immediate intervention?

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

Correct answer: C

Rationale: The correct answer is C. Crackles in the lungs indicate fluid overload, a common issue in heart failure patients. Immediate intervention is necessary to prevent worsening heart failure symptoms and potential complications. A heart rate of 60 beats per minute and a blood pressure of 100/60 mmHg are within normal ranges for many individuals and do not typically require immediate intervention in this context. The presence of a new murmur may be important to monitor but is not the priority when crackles in the lungs suggest fluid overload.

5. A client with a history of rheumatoid arthritis is prescribed methotrexate. Which laboratory value should the nurse monitor closely?

• A. Liver function tests
• B. Complete blood count
• C. Serum creatinine
• D. Prothrombin time

Correct answer: C

Rationale: Serum creatinine should be closely monitored in a client receiving methotrexate, as the medication can cause nephrotoxicity. Monitoring serum creatinine levels helps assess kidney function and detect potential nephrotoxic effects of methotrexate. Liver function tests (Choice A) are important to monitor for hepatotoxicity caused by methotrexate. While methotrexate can cause bone marrow suppression, leading to anemia, leukopenia, and thrombocytopenia, monitoring a complete blood count (Choice B) is essential but not the priority in this case. Prothrombin time (Choice D) is not typically affected by methotrexate therapy and is not the primary laboratory value to monitor in this situation.
