Dr. Doesn't Do Math orders the following: Give Randomamyocin 40 mg/kg/day divided in 6 equally divided doses. The patient weighs 215 pounds. On hand you have 150 mg in 10 mL of elixir. How much will you give for each dose? Round to the nearest whole number in all conversions and calculations.

When presented with problems like this follow a systematic approach and you will do fine. 1.) What is our weight in kg? 215 lbs/ 2.2 = 97.7 = 98 kg 2.) What is the ordered dose? 40 mg X 98 kg = 3,920 mg/day The doctor wants it given in 6 equally divided doses so we are not quite done. 3,920 mg/6 =653.3 = 653 mg per dose 3.) 653 mg/150 mg X 10 mL = 43.5 = 44 mL of elixir for each dose for this patient.

If a bag of Dennyophed has 500 mg in 250 mL how many micrograms are in each mL?

You can solve this problem one of two ways the important thing is that you pick a method and stick with it if it works for you. Version A: 1.) How many micrograms are in the bag? 500,000 micrograms. (knowing that 1 mg = 1,000 mcg) 2.) How many micrograms are in each mL? 500,000 mcg/250 mL = 2,000 mcg/mL Version B: 1) How many mg/mL 500 mg/ 250 mL = 2 mg/mL 2) 2 mg = 2,000 mcg (knowing 1 mg = 1,000 mcg) so there are 2,000 mcg/mL
