Question

A doctor orders a dosage of 5 ml of medicine every 4 hours for 8 days how many fluid ounces of medicine should be purchased

Help sole

Answer 1

First work out how many ml are required.
24 hours in a day, every 4 hours needs medicine. So six times a day needs medicine
6 x 8 = 48 doses
each dose is 5 ml
48 x 5 = 240 ml required
each ml is 0.033814 ounces
240 x 0.033814 = the ounces that need to be purchased.
