BSA Dosage Calculation Practice Questions (mg/m²)
Practise turning a supplied body surface area and an mg/m² order into a patient-specific dose. Progress into Mosteller BSA calculation, /dose versus /day wording, maximum-dose checks and precision boundaries.
BSA medication dosing practice
Quick review before you start
If a current BSA and an order in mg/m² are supplied, multiply the BSA in m² by the prescribed mg/m² to calculate the patient dose in mg. Calculating BSA itself is a separate step and should use the formula required by the question, protocol or approved system.
Formula
patient dose (mg) = BSA (m²) × prescribed dose (mg/m²)
Keep BSA in m² and mg/m² visible so m² cancels. Apply any supplied dose cap or maximum only on the basis stated in the question.
Sample question
A fictional worksheet supplies BSA = 1.60 m² and a practice order of 25 mg/m² per dose. What dose does that represent?
1.60 m² × 25 mg/m² = 40 mg
Answer: 40 mg per dose
What these questions practise
- direct BSA × mg/m² dose calculations
- Mosteller BSA within a medication-maths question when height and weight are supplied
- per-dose versus per-day mg/m² wording
- supplied BSA caps and final-dose maximum checks
- precision, rounding and source-state boundaries in BSA dosing problems

What the learning states mean
Learned means the lesson is complete. Practised means you have attempted questions. Secure requires a strong unassisted run. Mastered requires strong evidence again after time has passed. Review due means a previously stronger skill is ready for retrieval again.
