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
