Ati Rn Adult Medical Surgical 2023 Proctored Exam
Calculation
A nurse is preparing to infuse dextrose 5% in 0.45% sodium chloride 500 mL IV bolus over 4 hr. The drop factor of the manual IV tubing is 60 gtt/mL. The nurse should set the IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
gtt/min
Explanation & Rationale
Step 1: Convert hours to minutes 4 hr × 60 min/hr = 240 min Step 2: Multiply volume by drop factor 500 mL × 60 gtt/mL = 30,000 gtt Step 3: Divide by time in minutes 30,000 ÷ 240 min = 125 gtt/min Step 4: Final IV rate 125 gtt/min
