A healthy adult has a creatinine clearance of 120 mL min⁻¹. How many litres of plasma are cleared of creatinine each day?
Answer
172.8
The correct answer is 172.8 — Answer: 172.8 litres per day.
Step-by-step solution
- Convert clearance to per minute: 120 mL min⁻¹ = 0.12 L min⁻¹.
- Multiply by minutes in a day: 0.12 L min⁻¹ × 60 min h⁻¹ × 24 h d⁻¹ = 172.8 L d⁻¹.
- Answer: 172.8 litres per day.
Common mistake: Using 120 mL min⁻¹ directly as litres per minute without conversion
