A female patient is to receive one litre of Hartmann's solution over 12 hours. What is the drip rate if the administration set gives 15 gtt/mL?

Calculating the drip rate means turning the total volume to be infused and the total infusion time into a drops-per-minute rate using the IV set’s drop factor. Here, 1000 mL is to be given over 12 hours, and the set delivers 15 drops per mL.

Convert time to minutes: 12 hours × 60 minutes/hour = 720 minutes.

Use the formula: drip rate (gtt/min) = (volume in mL × drop factor) ÷ time in minutes.

So: (1000 mL × 15 gtt/mL) ÷ 720 min = 15000 ÷ 720 ≈ 20.83 gtt/min.

Drop rates are given as whole drops, so round to the nearest whole drop: 21 gtt/min.

That matches the correct choice.
