Nursing Elites

1. The nurse is caring for a client with chronic heart failure who is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?

• A. Serum potassium of 3.0 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 1.8 mg/dL
• D. Blood glucose of 200 mg/dL

Correct answer: A

Rationale: A serum potassium level of 3.0 mEq/L is most concerning in a client receiving furosemide as it indicates hypokalemia, which requires immediate intervention. Hypokalemia can lead to serious cardiac arrhythmias, which can be life-threatening. Serum sodium of 135 mEq/L and serum creatinine of 1.8 mg/dL are within normal ranges and do not require immediate intervention in this case. Blood glucose of 200 mg/dL is elevated but does not pose an immediate threat to the client's life in the context of heart failure and furosemide therapy.

2. A client with rheumatoid arthritis is prescribed methotrexate. Which laboratory value should the nurse monitor closely?

• A. White blood cell count of 10,000/mm³
• B. Hemoglobin of 12 g/dL
• C. Liver function tests
• D. Platelet count of 150,000/mm³

Correct answer: C

Rationale: The correct answer is C: Liver function tests. Methotrexate can cause hepatotoxicity, making it essential to closely monitor liver function tests in clients receiving this medication. Monitoring white blood cell count, hemoglobin, or platelet count is not specifically required for methotrexate therapy and would not provide relevant information regarding potential adverse effects of the medication.

3. A client who is post-op day 1 after abdominal surgery reports pain at the incision site. The nurse notes the presence of a small amount of serosanguineous drainage. What is the most appropriate nursing action?

• A. Apply a sterile dressing to the incision.
• B. Reinforce the dressing and document the findings.
• C. Remove the dressing and assess the incision site.
• D. Notify the healthcare provider.

Correct answer: B

Rationale: The correct answer is to reinforce the dressing and document the findings. It is important to monitor the incision site closely after surgery, especially when there is a small amount of serosanguineous drainage. Reinforcing the dressing helps maintain cleanliness and pressure on the wound. Documenting the findings is crucial for tracking the client's progress and alerting healthcare providers if necessary. Applying a sterile dressing (Choice A) may not be needed if the current dressing is intact. Removing the dressing (Choice C) can increase the risk of contamination. Notifying the healthcare provider (Choice D) is not the first step for minor drainage on post-op day 1.

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

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

Correct answer: C

Rationale: Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in assessing kidney function because contrast agents can potentially worsen renal function, leading to contrast-induced nephropathy. Monitoring serum creatinine helps in identifying patients at risk and taking necessary precautions. Serum potassium (Choice A) is important in conditions like hyperkalemia but is not the priority before a contrast CT scan. Blood urea nitrogen (BUN) (Choice B) is another renal function test but is not as specific as serum creatinine for assessing kidney function. Serum glucose (Choice D) is important in monitoring blood sugar levels, especially in diabetic patients, but it is not directly related to the risk of contrast-induced nephropathy in this scenario.

5. A client is admitted with a diagnosis of pneumonia and is receiving IV antibiotics. Which assessment finding indicates that the treatment is effective?

• A. Client reports less chest pain.
• B. Client's white blood cell count is decreasing.
• C. Client has a decreased respiratory rate.
• D. Client has clear breath sounds.

Correct answer: D

Rationale: The correct answer is D. Clear breath sounds indicate that the pneumonia is resolving and the treatment is effective. Breath sounds are often muffled or crackling in pneumonia due to the presence of fluid or inflammation in the lungs. Clear breath sounds suggest that the air is moving freely through the lungs, indicating improvement. Choices A, B, and C are less specific indicators of pneumonia resolution. While less chest pain and a decreasing white blood cell count can be positive signs, they are not as direct in indicating the effectiveness of pneumonia treatment as the presence of clear breath sounds. A decreased respiratory rate could be seen in various conditions and may not solely indicate the resolution of pneumonia.
