Medication Math

• Metric System - - mL, L, gram• Apothecary System – grain, minim, dram, ounce,

pint, quart, gallon, pound• Apothecary metric conversion - clock• Household – tsp, tbsp, ounce, pint, qt, gallon• Solutions - %, 1:100 vs. 1:10• Converting Measurement Units• Dosage Calculation Formulas

Calculation Formulas

• Ratio / Proportion: shows relationship between two ratio’s – The order is for 10 mg and we have 8 mg per mL.

8 mg/ 1 mL = 10 mg / X mL 8X=10

X=10/8 X = 1.25 mL

Calculation Formulas

• D/H X Q (Dose, Have, Quantity)• Dose ordered 10 mg; have 5 mg per ml

10/5 X 1 = 2 mL

• Solid medication – Q is always one

• Liquid medication – Q will vary. If there is 5 mg in 10 mL, the Q is 10

10/5 X 10 = 20 mL

Drug Measure Rules

• Use Arabic

• Fractions most often stated as decimals

• Use zero rules!!!

• Space goes between number and unit of measurement i.e. 1 mg

• Symbol follows the number with the exception of gr, oz and dr

• Use correct abbreviations
