A nurse is teaching the parent of a newborn about car seat safety.Which of the following statements should the nurse make?

Choice A rationaleRear-facing car seats support a baby’s head and spine during sudden stops or collisions. Experts recommend maintaining this position until 2 years to reduce injury risk.Choice B rationalePositioning the retainer clip on the upper abdomen risks internal organ damage during a crash. Proper placement is across the chest at armpit level to safely restrain movement.Choice C rationaleA 90-degree angle would force a newborn upright, compromising the airway. The recommended angle is 30–45 degrees to maintain an open airway and adequate breathing.Choice D rationaleHarness straps should be positioned at or below the shoulders, not above, to prevent the baby from sliding upward, which increases the risk of ejection during an accident.
