A nurse is teaching a newly licensed nurse about infant safety. Which of the following information should the nurse include in the teaching?

A. Provide an infant with a one-piece pacifier for non-nutritive sucking. Correct. A one-piece pacifier is recommended to prevent choking hazards associated with pacifiers that can come apart.B. Place an infant who is 5 months old in a high chair to feed. Infants typically do not have the necessary motor control to sit safely in a high chair until around 6 months of age when they can sit with minimal support.C. Secure the infant's car seat behind an airbag. It is unsafe to place a car seat behind an airbag. Airbags can deploy with great force and potentially injure an infant. The safest place for a car seat is the back seat, away from airbags.D. Position a 1-month-old infant supine on a soft mattress. Infants should be placed supine (on their back) to sleep to reduce the risk of sudden infant death syndrome (SIDS), but a firm mattress should be used, not a soft one, to prevent suffocation hazards.
