 Formulas for dose calculations
Definition
 BASIC FORMULA: Dose desired/dose on hand = dose administered D/H=X Solutions labels mg/mL BASIC FORMULA for solution admin is D/H X Quantity = Volume Administered D/H X Q = V DIMENSIONAL ANALYSIS (DA) – a method of drug calculation where the focus is on the units of measure; e.g. order is 10 mg diazepam, dosage on Hand is 5mg/mL, how much to administer? Start by writing mL = b/c will administer a liquid Then, numerator is the same unit, so put the dosage strength with numerator as same unit mL = 1mL/5mg Then multiply by desired dose with mL now as the denominator, so mL= 1mL/5mg X 10mg/XmL Solve for X Ok……..
