Weight-Based Dosage Calculation Practice Questions
Practise nursing weight-based dosage calculations using mg/kg and mg/kg/day. Progress from identifying the meaning of the order to kg conversion, per-dose versus per-day wording, divided doses and multi-step dose-to-volume problems.
Weight-based dosage calculation practice
Quick review before you start
Multiply the verified weight in kilograms by the ordered mg/kg rate to find the medication amount in mg. Treat mg/kg/dose as an amount for each dose. Treat mg/kg/day as a 24-hour total and divide only when the order states that the daily amount is split into doses.
Formula
dose (mg) = weight (kg) × ordered dose rate (mg/kg)
If the question asks for mL, first find the medication amount in mg, then use the supplied concentration as a separate second step. Do not invent a concentration or maximum dose that was not provided.
Sample question
A practice order is 10 mg/kg/dose for an 18 kg patient. What medication amount is required for one dose?
18 kg × 10 mg/kg/dose = 180 mg/dose
Answer: 180 mg per dose
What these questions practise
- interpreting mg/kg/dose and mg/kg/day
- converting source-supplied pounds to kilograms when required
- calculating a medication amount from kg × mg/kg
- dividing a daily total into the stated number of equal doses
- continuing from a weight-based mg result to mL only when concentration is supplied

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.
