Using the APLS formula, what is the estimated weight of a 2-year-old child?
Answer and explanation
Correct answer: A. 12 kg
- Step 1: The APLS formula for ages 1 to 5 years is weight = (age + 4) x 2.
- Step 2: (2 + 4) x 2 = 12 kg.
Answer
12 kg.
Why not the others: '14 kg' adds two kilograms to the estimate; '6 kg' uses 3 kg per year of age; '18 kg' multiplies by 3 instead of 2.
