Do not provide the unit of measurement. Only provide the number. Round to one decimal place (tenths).
Answer and Explanation

The Correct Answer is ["2.5"]

Ordered dose = 125 mcg

Available concentration = 0.05 mg/mL = 50 mcg/mL

Volume to administer = Ordered dose ÷ Concentration
= 125 ÷ 50
= 2.5

Correct Answer is ["17.7"]

Explanation

First, convert the child’s weight from pounds to kilograms:
65 ÷ 2.2 = 29.5 kg

Next, calculate the dose:
15 mg × 29.5 = 442.5 mg per dose

Now, use the concentration (125 mg/5 mL → 25 mg/mL):
442.5 ÷ 25 = 17.7

Answer: 17.7
