Calculation
A nurse is preparing to administer Ringer's lactate by continuous IV infusion at 120 mL/hr. The drop factor of the manual IV tubing is 60 gtt/mL. The nurse should set the manual 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
Rationale: IV rate = 120 mL/hr Drop factor = 60 gtt/mL Step 1: Convert hours to minutes: 120 mL/hr ÷ 60 min/hr = 2 mL/min Step 2: Calculate gtt/min: 2 mL/min × 60 gtt/mL = 120 gtt/min Final Answer: 120 gtt/min
