Study Notes
Weight-based Calculations
Importance of Weight-based Calculations in Paediatrics
- In paediatrics, weight-based calculations are crucial to ensure accurate medication dosing, as children's weights vary greatly.
- Weight-based calculations help to minimize the risk of medication errors and adverse effects.
Factors to Consider
- Weight units: Ensure that the weight is in the correct units (e.g., kg, g, lb) to avoid calculation errors.
- Dose units: Verify that the dose units match the weight units (e.g., mg/kg, mcg/kg).
Formula for Weight-based Calculations
- Dose (mg) = Dose (mg/kg) x Weight (kg)
- Dose (mcg) = Dose (mcg/kg) x Weight (kg)
Examples of Weight-based Calculations
- A child weighing 10 kg requires a medication dose of 5 mg/kg. Calculate the dose in mg:
- Dose (mg) = 5 mg/kg x 10 kg = 50 mg
- A child weighing 5 kg requires a medication dose of 2 mcg/kg. Calculate the dose in mcg:
- Dose (mcg) = 2 mcg/kg x 5 kg = 10 mcg
Tips for Accurate Calculations
- Always use the correct weight and dose units.
- Verify calculations before administering medication.
- Consider using a paediatric dose calculation formula sheet or a calculator to minimize errors.

Formulae for Weight-based Calculations
- Dose (mg) = Dose (mg/kg) x Weight (kg)
- Dose (mcg) = Dose (mcg/kg) x Weight (kg)
Examples of Weight-based Calculations
- For a 10 kg child, a 5 mg/kg medication dose is calculated as: Dose (mg) = 5 mg/kg x 10 kg = 50 mg
- For a 5 kg child, a 2 mcg/kg medication dose is calculated as: Dose (mcg) = 2 mcg/kg x 5 kg = 10 mcg
Tips for Accurate Weight-based Calculations
- Always use correct weight and dose units to avoid errors.
- Verify calculations before administering medication to ensure accuracy.
- Use a paediatric dose calculation formula sheet or a calculator to minimize errors.
