A nurse is reinforcing teaching about car seat safety with a parent of a newborn. Which of the following statements by the parent indicates an understanding of the teaching?

A. "I should enable the airbag when my baby is in the front seat of the car." Airbags deploy with significant force and can cause severe injury or fatal trauma to an infant in a car seat, especially if placed in the front seat. The safest position for an infant is in the back seat, rear-facing, as this provides the best protection in the event of a crash. If the front seat must be used, the airbag should be deactivated to prevent impact injuries. B. "I should position the car seat's retainer clip at the level of my baby's belly button." The car seat’s retainer clip should be positioned at armpit level to properly secure the harness and keep the baby restrained during a collision. If the clip is placed too low, such as at the belly button, the harness straps may not fit snugly around the shoulders, increasing the risk of the baby slipping out of the seat upon impact. C. "I should place my baby in the car seat at a 90-degree angle." A 90-degree angle is too upright for a newborn and can lead to airway obstruction due to the infant's weak neck muscles and large head size. The car seat should be reclined at approximately 45 degrees to maintain an open airway and prevent the baby’s head from falling forward, which could restrict breathing and cause positional asphyxia. D. "I should keep my baby rear-facing in the car seat until she is 2 years old." Rear-facing car seats provide optimal protection by supporting the baby’s head, neck, and spine in the event of a crash, reducing the risk of serious injury. The American Academy of Pediatrics recommends keeping infants in a rear-facing position until at least the age of 2 or until they exceed the car seat's height and weight limits. This positioning distributes crash forces more evenly across the child's body, minimizing the risk of spinal cord and head injuries.
