This 9-page printable guide teaches nursing students to calculate drug doses accurately. Each worked example states the order, works through the problem step by step in a table with a rationale for each step, and gives the answer. Fractions are typeset as stacked fractions, so the setup looks the way it does on paper.

What’s included:

Metric and household equivalents table
Safe dose-writing rules from the Joint Commission “Do Not Use” list and ISMP (leading zeros, trailing zeros, “units”)
Rounding rules for tablets, liquids, injections, IV pump rates and drip rates
Three calculation methods: formula method (D/H × Q), ratio and proportion, and dimensional analysis, with a side-by-side diagram solving the same problem two ways
18 worked examples:
Oral: tablets, tablets with a unit conversion, oral suspensions
Injections: doses under 1 mL, doses in units, reconstitution of a powder
Weight-based: mg/kg dosing and a pediatric safe dose range check
Body surface area: the Mosteller formula with a dose per m²
IV: pump rate in mL/h, gravity drip rate in gtt/min, small-volume infusions, infusion time
Continuous infusions: heparin in units/h, dopamine in mcg/kg/min, and working back from a running rate to the dose
10 practice problems with a full answer key showing each setup
