A nurse is caring for a newborn who is formula-fed. The newborn takes 0.5 oz of formula at 0800, 1 oz at 1100, 0.5 oz at 1300, 0.5 oz at 1600, and 0.5 oz at 1830. How many mL of formula should the nurse record as the client's intake for the shift?

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:

Acrocyanosis, or bluish discoloration of the hands and feet, is common in the first 24 hours after birth and is typically not a cause for concern.

Choice B rationale:

A newborn not voiding within 18 hours may need evaluation, but it is not as urgent as a potential infection.

Choice C rationale:

A newborn who is 24 hours old and has not passed meconium is not the most critical concern among the options provided. While meconium (the baby's first stool) should be passed within the first 24-48 hours, a slight delay may not be an immediate cause for concern.

Choice D rationale:

The nurse should prioritize seeing the newborn with an axillary temperature of 37.8°C (100° F), as this could indicate an infection or other serious condition requiring immediate attention.
