A nurse is educating new parents on Sudden Infant Death Syndrome (SIDS) prevention. Which instruction is most critical for reducing the risk of SIDS?

The correct answer to the question "A nurse is educating new parents on Sudden Infant Death Syndrome (SIDS) prevention. Which instruction is most critical for reducing the risk of SIDS?" is Option C: Ensure the infant sleeps on their back on a firm surface.

The other options — A) Place the infant to sleep on their stomach, B) Use soft bedding and toys in the crib, D) Allow the infant to sleep in an adult bed with parents — are incorrect for this NCLEX-RN Exam Prep question. As explained above: Placing infants on their back to sleep on a firm sleep surface is the most effective strategy to reduce the risk of SIDS. Soft bedding, stomach sleeping, and co-sleeping in an adult bed increase risk.
