Section I — Conversions and Calculation Foundations
Question 1
A pediatric client weighs 26.4 lb. Convert the weight to kilograms.
Worked Solution
Use:
26.4 lb ÷ 2.2 = 12 kg
Answer: 12 kg
Rationale: Pediatric weight-based calculations use kilograms rather than pounds.
Question 2

,Worked Solution
0.75 × 1,000 = 750 mg
Answer: 750 mg
Question 4
Convert 1,250 mcg to milligrams.
Worked Solution
1,000 mcg = 1 mg
1,250 ÷ 1,000 = 1.25 mg
Answer: 1.25 mg
Question 5
Convert 0.25 mg to micrograms.
Worked Solution
1 mg = 1,000 mcg
0.25 × 1,000 = 250 mcg
Answer: 250 mcg
Question 6
Convert 1.2 L to milliliters.

A simulated order requires 225 mg. The available concentration is 150 mg/5 mL.
Worked Solution
225 ÷ 150 × 5
= 1.5 × 5
= 7.5 mL
Answer: 7.5 mL
Question 11
A simulated liquid contains 160 mg per 5 mL. The exercise calls for 320 mg.
Worked Solution
320 ÷ 160 × 5
=2×5
= 10 mL
Answer: 10 mL
