Question

1\. A client with hypertension has an order for furosemide. Which lab finding should be reported to the physician? A. Phosphorus 2.5 mEq/L B. Potassium 1.8 mEq/L C. Calcium 9.4 mg/dl D. Magnesium 2.4 mEq/L

Short answer

Answer: Potassium 1.8 mEq/L

Step-by-step solution

Examine Each Option

Look at each lab finding, compare the results to normal ranges, and consider if the result is relevant in the context of a patient taking furosemide. Option A: Phosphorus 2.5 mEq/L Normal range: 2.5 - 4.5 mEq/L No problem with this value. Option B: Potassium 1.8 mEq/L Normal range: 3.6 - 5.2 mEq/L This value is significantly lower than the normal range. Furosemide is a potassium-wasting diuretic, meaning it can cause low potassium (hypokalemia). Option C: Calcium 9.4 mg/dl Normal range: 8.6 - 10.3 mg/dl No problem with this value. Option D: Magnesium 2.4 mEq/L Normal range: 1.7 - 2.4 mEq/L No problem with this value.

Choose the Lab Finding to Report

Since the potassium level (1.8 mEq/L) is significantly lower than the normal range and furosemide can cause hypokalemia, the nurse should report this lab finding to the physician.

Select the correct answer

Option B (Potassium 1.8 mEq/L) is the correct answer based on the analysis and the significance of furosemide's potential to cause hypokalemia.
