Which of the following is a common risk factor for otitis media in children?

A. A series of casts will be made for the infant soon after birth. The Ponseti method, the gold standard for treating clubfoot, involves gentle manipulation of the foot and application of a series of plaster casts that are changed weekly. This treatment usually begins shortly after birth to take advantage of the newborn’s soft tissues and bones, which are more easily repositioned.
B. An orthotic brace at 6 months of age is not the initial treatment. Bracing is used later in the treatment process after the foot has been corrected with casting to maintain alignment and prevent relapse.
C. Surgery performed in utero is not a treatment option for clubfoot. In severe cases unresponsive to casting, surgery may be required after birth, but intrauterine correction is not standard practice.
D. Monitoring and physical therapy alone are not sufficient to correct clubfoot. Without casting or surgical intervention, the deformity will persist and lead to long-term mobility issues.

A. Skin-to-skin contact promotes bonding and thermoregulation; it does not increase respiratory infection risk.
B. A dry environment can dry mucous membranes, making the infant more susceptible to infection.
C. A cool mist humidifier keeps the airway moist, reduces mucus thickening, and helps prevent respiratory infections, which infants with Down syndrome are at increased risk for due to hypotonia and airway abnormalities.
D. High-sugar formula has no role in infection prevention and could contribute to other health issues.
