Exhibit 1. How can the nurse assess the successful transition of the respiratory system in the newborn? (Select All that Apply.).

Choice A rationale:

The Moro reflex is a normal finding in newborns, including those born post-term. It is a primitive reflex that should be present and indicates a healthy neurological system.

Choice B rationale:

Vernix, a protective white substance that coats the skin in utero, is typically absent or minimal in post-term newborns due to its decreased production as gestation progresses. Therefore, it would not be expected in a post-term infant.

Choice C rationale:

Lanugo, the fine hair covering a newborn's body, is usually present in greater amounts in preterm infants. By the time a newborn is post-term, lanugo is typically sparse or absent, making it an unlikely finding.

Choice D rationale:

This maneuver assesses the flexibility of the newborn's joints. Post-term infants tend to have reduced flexibility and increased muscle tone, making this maneuver more difficult or restricted in this population.

Choice A rationale:

Drying the baby thoroughly is not directly related to assessing the successful transition of the respiratory system. It is essential for warmth and comfort but does not provide specific information about the respiratory system.

Choice B rationale:

Suctioning the mouth and nose with a bulb syringe to clear mucus is important to ensure the airways are clear and the newborn can breathe effectively. This action helps assess the airway patency and successful initiation of breathing.

Choice C rationale:

Observing the chest and abdomen is crucial to assess the respiratory effort and symmetry. Normal chest movements and equal rise and fall of the abdomen indicate a successful transition of the respiratory system.

Choice D rationale:

Counting the number of respirations per minute is essential to determine if the respiratory rate falls within the expected reference range (around 30-60 breaths per minute for a newborn) and if there are any irregularities.

Choice E rationale:

Observing the color of the mucous membranes is important as cyanosis (blue discoloration) may indicate inadequate oxygenation. Pink mucous membranes are a positive sign, indicating a successful transition of the respiratory system.
