Question

A patient is on a continuos intravenous drip for a drug and he needs to be dosed at a rate of 25mg/h , the drip is set to administer 10 drops of the fluid per hour with 4 drops equalling 1 ml in a volume, what is the concentration of the drug

Answer 1

If you need to set this up on an IV infusion pump, use the formula, volume (mL) divided by time (min), multiplied by 60 min over 1 hour, this equals the IV flow rate in mL/hr. Using this formula, 100 mL divided by 30 min, times 60 min in 1 hr, equals 199.9, rounded to 200 mL/hr
