The mother of an 8-month-old baby who has developed respiratory syncytial virus (RSV)/bronchiolitis wants to know which factors contribute to the risk of contracting RSV. Which response by the nurse is appropriate?
A) "There is a higher risk in children who are being breastfed."
B) "There is no way to avoid the illness."
C) "There is a higher risk in children who are exposed to secondary cigarette smoke."
D) "It is seen more frequently in children who do not attend daycare."
Answer: C
Risk for RSV is higher when the parent or caregiver smokes. Tobacco smoke increases mucus production and reduces the action of cilia within the airway passages. Exposure to secondhand smoke is thought to alter maturation of the respiratory epithelium. The risk of infection with RSV is higher for infants and toddlers who are not breastfed, live in homes with secondary cigarette exposure, attend daycare, live in crowded conditions, or are socioeconomically disadvantaged. RSV can be avoided by limiting these risk factors.
