Correct Answer: A

Rationale: The Moro reflex is a normal infantile reflex that is typically present at birth and disappears around 4-6 months of age. This reflex is triggered by a sudden loss of support or a loud noise, causing the infant to throw back the head and extend the arms in a gesture as if trying to grab something. In a situation where the newborn's birth was prolonged due to wide shoulders, there is a higher risk of injury to the brachial plexus (nerves that control arm movement) during delivery. Damage to the brachial plexus can result in weakness or paralysis of the affected arm, and this may impact the Moro reflex as it involves the arms' movement. Therefore, the nurse would be particularly observant for any abnormality or lack of response in the Moro reflex as it may indicate potential nerve injury related to the difficult birth.

Correct Answer: A

Rationale: Low potassium levels result from vomiting and purging.
