Divide the total volume in millilitres by the time in hours: mL/hr = volume ÷ time. If time is in minutes, convert to hours first.
Use gtt/min = (volume × drop factor) ÷ time in minutes for gravity tubing, using the drop factor printed on the tubing package.
mL/hr is the pump rate, while gtt/min is the manual drip rate for gravity infusions. Mixing them up is a common exam trap.
No. It is for education. Real infusions are verified against the order, pump settings, MAR, and institutional policy.
These answers are for nursing education and exam practice only and do not provide patient-specific medical advice.
Rate: 62.5 mL/hr
