Question 139: A child on an egg-elimination diet needs adequate protein intake. Which alternative protein source is most nutrient-dense and age-appropriate for a toddler?

Egg-free baked goods only
Lean meats, poultry, legumes, and dairy (if tolerated) (Correct answer)
White bread and pasta
Sports protein powders

Correct answer: Lean meats, poultry, legumes, and dairy (if tolerated)

Lean meats, poultry, legumes, and tolerated dairy provide high-quality protein and micronutrients to compensate for egg elimination in toddlers.

Question 140: Which nutrient deficiency is most specifically associated with impaired linear growth even in the absence of overt malnutrition?

Vitamin A
Zinc (Correct answer)
Iron
Vitamin D

Correct answer: Zinc

Zinc deficiency specifically impairs linear growth and is associated with growth faltering even when overall caloric intake appears adequate, due to zinc's role in IGF-1 signaling and cell proliferation.

Question 141: Why is it necessary to consider cultural factors in pediatric nutrition evaluation?

Reduces food intake
Limits food variety
Affects dietary habits and care plans (Correct answer)
Improves adherence to treatment

Correct answer: Affects dietary habits and care plans

Cultural factors profoundly influence a family's dietary habits, food preferences, and mealtime practices. Considering these factors is essential for pediatric nutrition evaluation because it allows healthcare providers to develop care plans that are culturally sensitive and acceptable. This approach increases the likelihood of adherence and successful nutritional outcomes for the child.

Question 142: Responsive feeding (also called cue-based or on-demand feeding) is important in infancy primarily because it:

Supports the development of healthy hunger and satiety regulation (Correct answer)
Prevents overfeeding by establishing a strict schedule
Reduces the risk of colic and gas
Ensures infants consume a set volume at each feeding

Correct answer: Supports the development of healthy hunger and satiety regulation

Responsive feeding, which responds to infant hunger and fullness cues rather than a fixed schedule, supports the development of self-regulation of intake and is associated with healthier long-term eating behaviors.

Question 143: Why is early detection of growth delays important?

To monitor physical activity
Timely intervention to promote healthy development (Correct answer)
To increase food intake
To track emotional growth

Correct answer: Timely intervention to promote healthy development

Early detection of growth delays is important because it enables timely intervention to address underlying causes, whether they are nutritional, medical, or environmental. Prompt action can prevent long-term negative impacts on a child's physical, cognitive, and emotional development. This proactive approach maximizes a child's potential for healthy growth and overall well-being.

Question 144: Why is dietary recall used in pediatric nutrition assessment?

To track physical activity
To measure food preferences
To estimate daily caloric needs
Helps assess eating habits and identify nutritional gaps (Correct answer)

Correct answer: Helps assess eating habits and identify nutritional gaps

Dietary recall methods, such as 24-hour recalls or food frequency questionnaires, are vital for understanding a child's typical food intake. By collecting information on what and how much a child eats, nutritionists can assess their eating habits, identify potential nutritional gaps or excesses, and tailor dietary recommendations accordingly. This provides a practical insight into the child's daily nutrition.

Question 145: A child diagnosed with non-IgE mediated food protein-induced enterocolitis syndrome (FPIES) most commonly reacts to which food?

Peanuts
Cow's milk or soy (Correct answer)
Eggs
Wheat

Correct answer: Cow's milk or soy

Cow's milk and soy are the most common FPIES triggers in infants, causing profuse vomiting and lethargy 1–4 hours after ingestion.

Question 146: How can nutrition education improve pediatric health outcomes?

Reduces food waste
Teaches food preservation techniques
Encourages weight loss
Empowers families to make informed food choices (Correct answer)

Correct answer: Empowers families to make informed food choices

Nutrition education empowers families by providing them with the knowledge and skills to make informed food choices. Understanding healthy eating principles allows parents and caregivers to select nutritious foods, prepare balanced meals, and establish positive eating habits for their children. This empowerment leads to improved dietary quality, better health outcomes, and a reduced risk of nutrition-related diseases.

Question 147: Energy requirements per kilogram of body weight are highest during which period of childhood?

School age (6–10 years)
Early adolescence (10–13 years)
Late adolescence (15–18 years)
Infancy (0–6 months) (Correct answer)

Correct answer: Infancy (0–6 months)

Infants have the highest energy requirements per kilogram (~100–120 kcal/kg/day) relative to body weight due to the extremely rapid rate of growth and high metabolic rate during the first 6 months of life.

Question 148: A child with phenylketonuria (PKU) is transitioning to adult care. Which dietary strategy remains essential throughout life?

Strict low-phenylalanine diet must continue lifelong (Correct answer)
Protein restriction is no longer necessary after brain development is complete
Medical formula can be discontinued once solid food variety is adequate
Phenylalanine-free diet can be liberalized after puberty

Correct answer: Strict low-phenylalanine diet must continue lifelong

Lifelong adherence to a low-phenylalanine diet is necessary in PKU to prevent cognitive decline, neuropsychiatric symptoms, and white matter changes in adults.

Question 149: A 6-month-old exclusively breastfed infant is diagnosed with vitamin D deficiency rickets. Which supplementation is standard of care in the US?

1000 IU vitamin D weekly
400 IU vitamin D daily from birth (Correct answer)
600 IU vitamin D daily from 6 months
200 IU vitamin D daily after 2 months

Correct answer: 400 IU vitamin D daily from birth

AAP recommends 400 IU of vitamin D daily for all breastfed infants beginning shortly after birth to prevent deficiency.

Question 150: Which anthropometric finding is most consistent with marasmus in a 2-year-old?

Severely low weight-for-height with muscle wasting and no edema (Correct answer)
Edema with normal weight-for-height
Bilateral pitting edema with adequate weight
Ascites with normal mid-upper arm circumference

Correct answer: Severely low weight-for-height with muscle wasting and no edema

Marasmus presents as severe wasting with very low weight-for-height, depleted fat and muscle stores, but without edema.
