The nurse has seen a 15-year-old girl and a 16-year-old boy during health surveillance visits. Which physical characteristics would be seen in both teenagers?

A. "His average daily intake should be about 3,000 calories.": This statement is incorrect because the average daily calorie intake for a toddler is much lower, typically ranging from 1,000 to 1,400 calories, depending on factors such as age, weight, and activity level.

B. "The quality of food I provide him is more important than the quantity.": This statement reflects an understanding of the importance of nutrient-dense foods in a toddler's diet rather than focusing solely on the quantity of calories consumed.

C. "Because he is such a picky eater, I will give him one of my vitamins each day.": While offering a vitamin supplement may seem like a solution to address nutritional gaps, it's important for toddlers to receive essential nutrients from a variety of foods rather than relying solely on supplements.

D. "I should expect him to have an increased appetite.": While toddlers may experience fluctuations in appetite, expecting a consistently increased appetite may not be accurate or indicative of healthy eating habits.

A. Myelination of the brain and spinal cord is a continuous process that begins during fetal development and continues through childhood and adolescence. While significant myelination

occurs during infancy and toddlerhood, it is not complete by 24 months. However, substantial progress in myelination does occur during the toddler years, contributing to the development of motor and cognitive skills.

B. Alveoli reach adult numbers by 3 years of age. This statement is incorrect. Alveoli continue to develop and increase in number after birth, reaching adult numbers around adolescence, not by 3 years of age.

C. Urine output in a toddler typically averages approximately 30 mL/hour. This statement is incorrect. Toddlers typically have higher urine output rates than adults due to their smaller

bladder capacity and higher metabolic rate. The average urine output for a toddler is around 1-2 mL/kg/hour, which varies depending on factors such as hydration status and activity level.

D. Toddlers typically have strong abdominal muscles by the age of 2. This statement is incorrect. While toddlers may develop some abdominal muscle strength through activities such as walking and climbing, their muscle tone and strength are still developing and may not be as strong as in older children or adults.
