A nurse is caring for a newborn whose mother voices concerns about sudden infant death syndrome (SIDS). The nurse should include which of the following statements in a discussion with the mother?

Choice A reason: Sleep apnea is not the main cause of SIDS. The exact cause of SIDS is unknown, but it is associated with brain abnormalities, prematurity, and environmental factors like prone sleeping. This statement is inaccurate, as sleep apnea is not a primary mechanism for SIDS. Choice B reason: SIDS rates have not been rising; they have declined since the 1990s due to campaigns promoting safe sleep practices, like back sleeping. This statement is factually incorrect, as current data show reduced incidence with adherence to safe sleep guidelines, making it inappropriate. Choice C reason: SIDS is not correlated with diphtheria, tetanus, and pertussis vaccines. Extensive studies show no link between vaccinations and SIDS; vaccines are safe and protective. This statement is misleading and contradicts evidence, making it incorrect for educating the mother about SIDS risks. Choice D reason: Placing infants on their backs to sleep significantly reduces SIDS risk by preventing airway obstruction and overheating, key environmental factors. This aligns with safe sleep guidelines, as back sleeping allows clear breathing, making it the correct and evidence-based statement for SIDS prevention education.
