A child must take 10 mL of cephalexin, an antibiotic, by mouth 2 times a day for 10 days. The solution is provided as a 50 mg/mL suspension. How many milligrams will the child have taken when the course of medication is over?
1 answer
50 mg/mL x 10 ml/dose x 2 doses/day x 10 days = ? mg. Note how the units cancel mL with mL; dose with dose; day with day. Unit left is mg. Isn't chemistry fun.
