Calculate IV drip rate in drops per minute and mL per hour. Enter volume, time, and drop factor for manual gravity drip rate nursing calculations.
Estimate creatinine clearance with Cockcroft-Gault equation for drug dosing. Enter age, weight, sex, and serum creatinine for kidney function assessment.
Calculate pediatric BMI and BMI percentile by age and sex. Uses CDC growth chart data for children ages 2–19 weight status screening.
Multiply patient body weight by ordered mg per kg dose. Use actual body weight unless protocol specifies ideal or adjusted weight.
Dose (mg) = Weight (kg) × Dose (mg/kg)Divide total milligrams by stock concentration to get draw volume from vial or oral suspension.
Volume (mL) = Dose (mg) ÷ Concentration (mg/mL)Always compare calculated dose against reference maximum per administration per drug reference.
Verify: Calculated Dose ≤ Adult/Pediatric Max Single DoseUpdated: July 2026
Daily dose 800 mg. If divided BID: 400 mg per dose. Suspension 250 mg/5 mL → 8 mL per dose.
975 mg dose. Vial 500 mg/mL reconstituted to 100 mg/mL → 9.75 mL. Verify against max single dose.
Some protocols use adjusted body weight for obesity or ideal weight for underweight. Follow institutional policy.
Compute weight-based medication doses for clinical and educational use. Enter patient weight, prescribed dose in mg/kg, and drug concentration to get total dose in mg and volume in mL for oral or injectable administration.
