Zones are general guidelines. Always follow drug-specific dosing protocols.
Dose = Weight (kg) × mg/kg ÷ frequency
70.00 kg × 10 mg/kg = 700.00 mg/day
700.00 mg ÷ 1 = 700.00 mg/dose
Inputs
Result
Total Daily Dose = 70 kg x 10 mg/kg = 700.00 mg. Dose per administration = 700.00 / 3 = 233.33 mg per dose, given three times daily.

Flow rate = 1000 mL / 8 hours = 125.0 mL/hr. Drip rate = (1000 x 20) / (8 x 60) = 20000 / 480 = 41.7 gtt/min.
Dose = Weight (kg) × Dose (mg/kg). Example: 70 kg patient, ordered 10 mg/kg = 70 × 10 = 700 mg total dose. If TID (3x daily), each dose = 700 ÷ 3 = 233 mg. Always verify against safe dose ranges.
| Patient Weight | Dose 5 mg/kg | Dose 10 mg/kg | Dose 15 mg/kg |
|---|---|---|---|
| 10 kg (child) | 50 mg | 100 mg | 150 mg |
| 25 kg (child) | 125 mg | 250 mg | 375 mg |
| 70 kg (adult) | 350 mg | 700 mg | 1050 mg |
| 100 kg (adult) | 500 mg | 1000 mg | 1500 mg |
Drip rate (gtt/min) = (Volume mL × Drop factor) ÷ Time (min). Example: 1000 mL over 8 hours with 15 gtt/mL set: (1000 × 15) ÷ 480 = 31 gtt/min. Count drops for 15 sec, multiply by 4.
| Volume/Time | 10 gtt/mL | 15 gtt/mL | 20 gtt/mL | 60 gtt/mL |
|---|---|---|---|---|
| 100 mL/hr | 17 gtt/min | 25 gtt/min | 33 gtt/min | 100 gtt/min |
| 125 mL/hr | 21 gtt/min | 31 gtt/min | 42 gtt/min | 125 gtt/min |
| 1000 mL/8hr | 21 gtt/min | 31 gtt/min | 42 gtt/min | 125 gtt/min |
| 500 mL/6hr | 14 gtt/min | 21 gtt/min | 28 gtt/min | 83 gtt/min |
Common conversions: 1 g = 1000 mg, 1 mg = 1000 mcg, 1 L = 1000 mL, 1 kg = 2.2 lbs. For concentration: mg/mL × volume mL = total mg. Example: 250 mg/5mL × 10 mL = 500 mg.
| From | To | Conversion | Example |
|---|---|---|---|
| grams (g) | milligrams (mg) | × 1000 | 1.5 g = 1500 mg |
| milligrams (mg) | micrograms (mcg) | × 1000 | 0.5 mg = 500 mcg |
| liters (L) | milliliters (mL) | × 1000 | 0.25 L = 250 mL |
| pounds (lbs) | kilograms (kg) | ÷ 2.2 | 154 lbs = 70 kg |
| teaspoon (tsp) | milliliters (mL) | × 5 | 2 tsp = 10 mL |
mL/hr = Total volume ÷ Hours. Example: 1000 mL over 8 hours = 1000 ÷ 8 = 125 mL/hr. For drugs: (Dose/hr × Volume) ÷ Concentration = mL/hr. Always verify pump settings.
| Total Volume | 4 hours | 6 hours | 8 hours | 12 hours |
|---|---|---|---|---|
| 250 mL | 63 mL/hr | 42 mL/hr | 31 mL/hr | 21 mL/hr |
| 500 mL | 125 mL/hr | 83 mL/hr | 63 mL/hr | 42 mL/hr |
| 1000 mL | 250 mL/hr | 167 mL/hr | 125 mL/hr | 83 mL/hr |
The 6 Rights: Right patient, Right drug, Right dose, Right route, Right time, Right documentation. Some add: Right reason, Right response. Always verify all rights before giving any medication.
Pediatric doses are always weight-based (mg/kg). Use actual weight, not estimated. Common formula: Child dose = (Weight in kg × Adult dose) ÷ 70 kg. Always verify against pediatric drug references.
| Child Weight | 15 mg/kg/day ÷ 3 doses | Per dose |
|---|---|---|
| 10 kg (22 lbs) | 150 mg/day | 50 mg |
| 15 kg (33 lbs) | 225 mg/day | 75 mg |
| 20 kg (44 lbs) | 300 mg/day | 100 mg |
| 25 kg (55 lbs) | 375 mg/day | 125 mg |
