CSP Growth & Development in Pediatrics 3

Question 1

Which growth chart is recommended for monitoring growth in children ages 2–20 years in the United States?

Accepted Answer

CDC 2000 Growth Charts

Answer

The CDC 2000 Growth Charts are recommended for children aged 2–20 years in the US, while the WHO standards are preferred for children 0–2 years of age.

Question 2

A premature infant born at 28 weeks gestation is now 6 months chronological age. What corrected age should be used when plotting growth on a standard growth chart?

Accepted Answer

3 months corrected age

Answer

Corrected age = chronological age minus weeks of prematurity (in months): 6 months − 3 months (12 weeks early) = 3 months corrected age; age correction is recommended until 24–36 months.

Question 3

What is the approximate expected daily weight gain for a healthy term newborn during the first 3 months of life?

Accepted Answer

20–30 g/day

Answer

Healthy term infants typically gain 20–30 grams per day (about 150–200 g/week) during the first 3 months, which is a key benchmark for assessing adequate nutrition and growth.

Question 4

In evaluating a child with short stature, an advanced bone age compared to chronological age is most suggestive of which condition?

Accepted Answer

Precocious puberty

Answer

Advanced bone age relative to chronological age is characteristic of precocious puberty, as sex steroids accelerate skeletal maturation and epiphyseal development.

Question 5

Which of the following developmental milestones is typically achieved by a healthy 12-month-old infant?

Accepted Answer

Pincer grasp with index finger and thumb

Answer

Pincer grasp (fine motor coordination with index finger and thumb) is typically achieved by 9–12 months; independent walking usually develops by 12–15 months and 50 words by approximately 24 months.
