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?

Choice A rationale: Enabling the airbag when the baby is in the front seat of the car is incorrect. Airbags can be dangerous for infants and young children, and it is recommended to keep them in the rear seat, preferably in a rear-facing car seat. Choice B rationale: Positioning the car seat's retainer clip at the level of the baby's belly button is incorrect. The retainer clip should be at armpit level to ensure proper positioning and safety. Choice C rationale: Keeping the baby rear-facing in the car seat until she is 2 years old is the correct understanding of car seat safety. This statement aligns with the American Academy of Pediatrics (AAP) recommendations, which suggest keeping infants rear-facing as long as possible, ideally until they reach the maximum height and weight limits of their car seat. Choice D rationale: Placing the baby in the car seat at a 90-degree angle is incorrect. The correct angle for a rear-facing car seat depends on the manufacturer's guidelines but typically ranges from 30 to 45 degrees. The 90-degree angle is not safe and can compromise the baby's airway.
