The health care provider orders 1000 mL of D5LR with 20 mEq KCl to run for 8 hours. Using an infusion set with a drop factor of 15 gtt/mL, the nurse calculates the flow rate to be:
1. 12 gtt/min
2. 22 gtt/min
3. 32 gtt/min
4. 42 gtt/min
ANS: 3
1000 mL ÷ 8 hr = 125 mL/hr; (15 gtt/mL ÷ 60 min) x 124 mL = 32 gtt/min.
