Using the APLS formula, what is the estimated weight of a 3-year-old child?
Answer and explanation
Correct answer: D. 14 kg
- Step 1: The APLS formula for ages 1 to 5 years is weight = (age + 4) x 2.
- Step 2: (3 + 4) x 2 = 14 kg.
Answer
14 kg.
Why not the others: '16 kg' adds two kilograms to the estimate; '9 kg' uses 3 kg per year of age; '7 kg' omits the doubling.
