360 mL of saline must run over 3 hours using tubing with a drop factor of 10 drops/mL. What is the drip rate in drops per minute?
Answer and explanation
Correct answer: B. 20 drops/min
- Step 1: Drops per minute = volume x drop factor / time in minutes.
- Step 2: 360 x 10 / (3 x 60) = 20 drops/min.
Answer
20 drops/min.
Why not the others: The time must be in minutes and the drop factor must multiply the volume; the other values leave out one of these steps.
