DoseDrill: Dosage Calculations

Get confident with dosage calculations through a few minutes of practice a day. DoseDrill writes every question as a real medication order, checks your answer instantly and walks you through the solution step by step.

Built for nursing students preparing for dosage calc exams in school and for the math on their licensing exam, and for nurses who want to keep their med math sharp.

SIX TOPICS, FROM BASICS TO IV
• Unit conversion: mcg, mg, g, kg, lb, mL, L, tsp and tbsp
• Tablets & capsules: desired over have (D/H × Q)
• Liquids & injections: mg/mL to volume
• Weight-based dosing: mg/kg per dose and per day, with a max dose check
• IV flow rate: pump rate in mL/hr
• IV drip rate: gtt/min with macro and micro drip sets (10, 15, 20 and 60 gtt/mL)

PRACTICE THAT ADAPTS
• Questions adjust to your level in each topic
• Type your answer on a number pad: no multiple choice to guess from
• Every solution shown step by step, from the D/H × Q formula to the final rounding
• See your answer on a syringe, pump or drip chamber
• Safe-writing reminders: leading zero (0.5 mL), no trailing zero (5 mL, not 5.0 mL)
