Question 1

A 6-month-old exclusively breastfed infant is at highest risk for deficiency of which nutrient?

Accepted Answer

Vitamin D

Answer

Breast milk is low in vitamin D, so exclusively breastfed infants should receive 400 IU/day supplementation per AAP guidelines.

Question 2

Which anthropometric index is most appropriate for assessing nutritional status in children aged 2–18 years?

Accepted Answer

BMI-for-age percentile

Answer

BMI-for-age percentile accounts for normal growth patterns and is the standard screening tool for overweight and obesity in children 2–18 years.

Question 3

An 80-year-old with poor appetite and muscle wasting has low serum albumin (2.8 g/dL). Which condition best explains the low albumin in this context?

Accepted Answer

Protein-energy malnutrition

Answer

Protein-energy malnutrition causes decreased hepatic synthesis of albumin, making it a marker of chronic nutritional depletion.

Question 4

What is the recommended daily iron intake for a 12-month-old toddler?

Accepted Answer

11 mg

Answer

The RDA for iron is 11 mg/day for children aged 7–12 months and remains at 7 mg/day for ages 1–3 years; however, for infants 7–12 months specifically the value is 11 mg.
