A 7-year-old boy is brought to the pediatric clinic by his parents for a routine check-up. They are concerned because he appears shorter than many of his classmates. His growth chart shows that he has dropped from the 50th percentile to the 10th percentile for height over the past two years. His parents are of average height. Physical examination reveals no dysmorphic features, and his developmental milestones are appropriate for his age. Which of the following is the most appropriate next step in the management of this patient? A) Reassure the parents and do nothing B) Initiate growth hormone therapy C) Order a complete blood count and thyroid function tests D) Obtain an X-ray to determine bone age E) Refer to a pediatric endocrinologist for further evaluation - ANSWER D) Obtain an X-ray to determine bone age Rationale: A child who has dropped significantly on the growth percentile chart, particularly crossing percentiles downwards, requires an evaluation to understand the underlying cause. An X-ray to determine bone age is a critical next step in assessing growth potential and distinguishing between conditions like constitutional growth delay and more serious growth pathologies.

An X-ray of the hand for bone age assessment is consistent with his chronological age. Which of the following is the most likely diagnosis? A) Growth hormone deficiency B) Familial short stature C) Constitutional growth delay D) Chronic illness E) Malnutrition - ANSWER Familial short stature Rationale: Given the child's consistent growth along the 5th percentile and the short
A 6-month-old infant's growth chart shows a head circumference that has crossed the 95th percentile, while height and weight are at the 50th percentile.
