A 65-year-old woman weighing 71 kg has a serum creatinine of 0.8 mg/dL. Using the Cockcroft–Gault equation, what is the estimated creatinine clearance (mL/min), rounded to the nearest whole number?
Answer and explanation
Correct answer: D. 79 mL/min
- Step 1: and multiply by 0.85 for women.
- Step 2: mL/min.
Answer
79 mL/min.
Why not the others: 92 mL/min: The sex correction factor was applied wrongly. 6656 mL/min: The factor 72 was left out. 215 mL/min: Age was added to 140 instead of subtracted.
