A nurse is teaching a new parent how to correctly use a car seat.Which of the following statements by the parent indicates an understanding of the teaching?

Choice A rationaleRear-facing car seats are safer for infants and toddlers because they provide better support for their head, neck, and spine in the event of a collision. The American Academy of Pediatrics recommends keeping children in rear-facing seats until they are at least 2 years old or until they reach the highest weight or height allowed by the manufacturer.Choice B rationaleA four-point harness is not sufficient for securing a baby in a car seat. A five-point harness, which includes two shoulder straps, two hip straps, and one crotch strap, provides more secure and effective restraint for infants.Choice C rationaleThe shoulder harness should be positioned in the slots at or below the baby's shoulders, not above, to ensure proper fit and restraint. Placing the harness above the shoulders can result in improper restraint and increased risk of injury in an accident.Choice D rationaleThe correct angle for a rear-facing car seat is typically 45 degrees, not 30 degrees. A 45-degree angle ensures the baby's airway remains open, preventing the head from falling forward and potentially causing breathing difficulties.
