Final answer:
The parents' correct understanding of home safety for a newborn is indicated by the statement that they will place their baby on his back to sleep, which aligns with SIDS prevention recommendations.
Step-by-step explanation:
The student asked about the indication of understanding proper home safety for a newborn as explained by a nurse. The correct answer is c. I will place my baby on his back when it is time for him to sleep.
The substantial amount of research on Sudden Infant Death Syndrome (SIDS) has shown that putting infants to sleep on their backs in cribs free of suffocation hazards such as blankets, pillows, or padded crib bumpers is essential. Keeping a baby's crib away from heat vents is also important to prevent overheating. These measures, along with ensuring no one smokes in the home and not placing caps on the baby's head during sleep, have contributed to a decrease in SIDS.
Consequently, statements like tying a pacifier around a baby's neck with yarn or keeping the crib close to heat vents reflect a lack of understanding of home safety recommendations and pose significant risks to the infant's health and safety.
