A client is brought to the emergency center for fluid replacement after running a marathon, and the healthcare provider prescribes a 500 mL bolus of 0.9% normal saline to be administered over 4 hours. The Infusion set delivers 10 gtt/mL, so the nurse should regulate the Infusion to deliver how many gtt/minute? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

Correct Answer: 21

Rationale: Infusion rate: 500 mL / 4 hours = 125 mL/hour. Flow rate: (125 Ã— 10) / 60 = 20.833 gtt/min, rounded to 21.
