MedicationsQuestion 39 of 100
A prescription reads: amoxicillin 400 mg/5 mL suspension, give 200 mg by mouth twice daily. How many mL should be given per dose?
a.1.25 mL
b.2.5 mL
c.5 mL
d.10 mL
Explanation
Since 400 mg is contained in 5 mL, 200 mg is half that amount, or 2.5 mL per dose. The 5 mL volume would deliver 400 mg, 10 mL would deliver 800 mg, and 1.25 mL would supply only 100 mg.
