Result
Amount to give10 tablets or mL
Ordered dose and strength on hand must be in the same unit (convert g, mg and mcg first). Tablets: give whole tablets, halves only if scored. Liquids: round mL to tenths, or as the syringe allows. For exam practice only. This is a study aid, never a clinical decision: always follow the prescription, local protocols and the product information.
Step-by-step solution
Desired over have times quantity
(D/H)·Q = (250/125)·5 = 10
Key formulas
- Dose from strength
- volume = dose / strength
- Weight-based dose
- dose = mg/kg × body weight
- Tablets
- number = dose / tablet strength
- Units
- 1 g = 1000 mg, 1 mg = 1000 mcg
