The nurse is assessing a 4-year-old boy whose mother was 40 years old when he was born. Which finding suggests this child has a genetic disorder?

Choice A rationale Feeding problems are a common, non-specific finding in early childhood and can be related to many different issues, such as poor latch, reflux, or developmental delays, and are not exclusively indicative of a genetic disorder like Down syndrome. Therefore, this observation is not specific enough to confirm a genetic etiology. Choice B rationale Nasal congestion and excess mucus are very common signs of upper respiratory infections or allergic rhinitis in young children. These findings reflect an inflammatory or infectious process in the nasal passages and are not recognized as a primary or specific physical characteristic of a genetic disorder. Choice C rationale Low-set ears are a recognized dysmorphic feature or minor congenital anomaly that is often associated with various syndromes, particularly those involving chromosomal abnormalities like Down syndrome, as they reflect atypical fetal development of the first and second branchial arches. Lobe creases, while a potential finding, are less specific than low-set placement. Choice D rationale Wheezing suggests obstruction or narrowing in the lower airways, typically associated with conditions like asthma, bronchiolitis, or foreign body aspiration. This is a respiratory symptom related to inflammation and bronchospasm and is not a typical, pathognomonic physical finding of a common genetic disorder.
