Correct Answer is B
Explanation
Choice A rationale
A front-facing car seat for an infant does not provide adequate protection in the event of a collision. Infants should always be in a rear-facing car seat to support their head, neck, and spine.
Choice B rationale
Using an infant model car seat designed specifically for the car ensures that the seat meets safety standards and is appropriate for the child's size and developmental needs, providing optimal protection.
Choice C rationale
Being able to fit a hand between the baby and the car seat harness indicates the harness is too loose. The harness should be snug enough that only one or two fingers can fit between the strap and the baby's chest to provide secure restraint.
Choice D rationale
A rear-facing car seat should not be placed in the front passenger seat due to the risk of injury from airbags. The safest position for a rear-facing car seat is in the back seat, away from active airbags.
Correct Answer is B
Explanation
Choice A rationale
Acrocyanosis is a common and typically benign condition in newborns, characterized by bluish discoloration of the hands and feet. It is not an immediate priority.
Choice B rationale
Respiratory distress is the priority assessment for a newborn immediately following a cesarean delivery. Ensuring the newborn has a patent airway and is breathing effectively is crucial for their survival and immediate well-being.
Choice C rationale
Hypothermia is a concern for newborns, but respiratory distress takes precedence as an immediate life-threatening condition.
Choice D rationale
Accidental lacerations can occur during a cesarean delivery, but they are usually not life-threatening and can be addressed after ensuring the newborn's respiratory status is stable. .
