A nurse is collecting data from a 6-month-old infant in the well child clinic.
Which of the following findings should the nurse expect?
Infant's birth weight is tripled.
Lateral incisors are present.
Posterior fontanel is closed.
Infant sits well without support.
The Correct Answer is C
Choice A rationale
The infant's birth weight typically doubles by 4-6 months and triples by 1 year of age. If an infant's weight has tripled at 6 months, it may indicate overnutrition or an underlying health condition.
Choice B rationale
Lateral incisors usually appear between 9 to 13 months. At 6 months, the central incisors are more likely to be emerging.
Choice C rationale
The posterior fontanel typically closes by 2 to 3 months of age. Therefore, by 6 months, it is expected to be closed.
Choice D rationale
Infants usually sit without support around 8 months. At 6 months, they may sit with support or briefly without support but not consistently.

Explanation
Step 1: lb ÷ (2.2 lb/kg) = 10 kg
Step 2:.5 mg/kg/day × 10 kg = 15 mg/day
Step 3: mg/day ÷ 4 doses/day = 3.75 mg/dose
Step 4:.75 mg ÷ 1 mg/mL = 3.75 mL per dose
The calculated answer is 3.8 mL (rounded to the nearest tenth)
