What you'll practice
Nine problem categories, from basic conversions to high-alert drips — the same math the NCLEX-PN and your exit exam test. Every problem is generated fresh, so you never run out.
Basic Unit Conversions
lb ↔ kg, mg ↔ mcg ↔ g, mL ↔ L, and household units (tsp / tbsp / oz).
Tablets & Capsules
Solid oral forms — how many tablets or capsules make up the ordered dose.
Oral & Injectable Liquids
Suspensions, oral solutions, and IM / IV / SubQ injections — solve for mL.
IV Flow Rate (mL/hr)
Total volume divided by total time for pump-based infusions.
IV Drip Rate (gtt/min)
Manual gravity tubing with a drop factor (10 / 15 / 20 / 60 gtt/mL).
Pediatric Weight-Based
mg/kg dosing with weight conversion (lb → kg) and concentration math.
Heparin & Insulin Drips
Units/hr ordered → mL/hr pump rate. High-alert calculations.
Critical Care Titrations
mcg/kg/min and mcg/min infusions — dopamine, norepinephrine, dobutamine.
Reconstitution
Powdered vials reconstituted with diluent — final concentration and dose volume.
