HESI RN Dosage Calculation Proctored Exam
Calculation
A client receives a prescription for 1 liter of lactated Ringer's IV to be infused over 8 hours. The IV administration set delivers 10 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
gtt/min
Explanation & Rationale
Step 1: Identify the total volume. 1000 mL Step 2: Identify the infusion time. 8 hours = 480 minutes Step 3: Calculate the infusion rate. 1000 ÷ 480 = 2.0833 mL/min Step 4: Calculate the drops per minute. 2.0833 × 10 = 20.833 Rounded to the nearest whole number = 21 gtt/min
