Question

You are to give ampicillin with a recommended dose of 25mg/kg to a child with a mass of 29kg. If stock on hand is 250mg/capsule how many capsules should be given?

Answer 1

3 capsules

Step-by-step explanation:

Step 1. Calculate the dose

You must administer 25 mg for each kilogram.

For a 29 kg child,

Dose = 29 kg × (25 mg/1 kg) = 725 mg

Step 2. Calculate the number of capsules.

1 capsule contains 250 mg.

No. of capsules = 725 mg × (1 capsule/250 mg) = 2.90 capsule ≈ 3 capsules

You can't split a capsule, so you administer 3 capsules.
