Free Pediatric Nutrition Exam Questions That Helps Candidates Pass

Vitamin K is administered to newborns to prevent hemorrhagic disease of the newborn. Newborns have immature liver function and low vitamin K stores, making supplementation critical. Vitamins A, D, and E are important later but not routinely given immediately at birth for bleeding prevention.

The best way to reduce screen time is to provide healthy alternatives, such as outdoor play, sports, and family activities. Completely banning devices is often unrealistic and may backfire. Structured limits and positive reinforcement work better. Reducing screen time helps prevent sedentary behavior and obesity.

BMI-for-age percentile is the best indicator for monitoring overweight and obesity in children and adolescents. Using WHO or CDC charts, children with BMI ≥85th percentile are overweight, and ≥95th percentile are obese. Weight-for-age does not account for height, while length-for-age and head circumference are only useful in younger children. Monitoring BMI percentiles helps predict risks of metabolic syndrome, diabetes, and cardiovascular disease, making it the most appropriate measure for school-aged children.

Colostrum is the first milk secreted by mothers in the immediate postpartum period and is highly concentrated in immunoglobulins, especially secretory IgA. These antibodies provide passive immunity, protecting infants from respiratory and gastrointestinal infections. Colostrum also contains higher amounts of leukocytes, growth factors, and antimicrobial peptides compared to mature breast milk. Although it is lower in fat and carbohydrates, its small volume is perfectly suited to meet the newborn’s stomach capacity while delivering concentrated protective components. Casein and fats are present but in lower amounts than later milk. Thus, colostrum plays a vital role in immunological defense during the infant’s early days of life.

Beef and other animal products (liver, poultry, fish) are rich in heme iron, which is absorbed more efficiently than non-heme iron from plant sources like spinach and lentils. Milk is low in iron and excessive intake may worsen anemia by displacing iron-rich foods. Non-heme iron absorption can be enhanced by vitamin C, but heme iron remains the best source for rapid correction of deficiency.
