A. The child has an excessive appetite and is at risk for obesity: Prader-Willi syndrome is characterized by hypothalamic dysfunction leading to hyperphagia and impaired satiety. Children develop an intense, persistent appetite that significantly increases the risk for obesity and related metabolic complications. Strict dietary supervision is a central component of management. B. The child exhibits advanced motor and language skills for their age: Children with Prader-Willi syndrome typically demonstrate developmental delays, including delayed motor milestones and speech development. Hypotonia and cognitive impairment contribute to slower skill acquisition rather than advanced abilities. This finding is inconsistent with the syndrome’s neurologic profile. C. The child demonstrates a high level of energy and requires minimal sleep: Prader-Willi syndrome is associated with low energy levels, reduced stamina, and sleep disturbances such as excessive daytime sleepiness or sleep apnea. Increased energy and reduced sleep needs are not typical features. Fatigue is more commonly observed. D. The child has a markedly increased muscle tone and strength: Hypotonia is a hallmark feature of Prader-Willi syndrome, particularly in infancy and early childhood. Decreased muscle tone contributes to feeding difficulties early in life and delayed motor development. Increased tone and strength do not align with the underlying neuromuscular findings.
