A nurse is preparing to examine a post-term newborn immediately following delivery. Which of the following findings should she expect to observe? (Select all that apply.).
A.
Moro reflex.
B.
Vernix in the folds and creases.
C.
Abundant lanugo.
D.
Heel to ear maneuverability.
For a post-term newborn (born after 42 weeks of gestation), the expected findings include:
- A. Moro reflex
- Correct. The Moro reflex, or startle reflex, is a normal finding in newborns, including those born post-term. This reflex should be present.
- B. Vernix in the folds and creases
- Incorrect. Vernix caseosa typically decreases and is often minimal or absent in post-term newborns because it has been absorbed or worn away over time.
- C. Abundant lanugo
- Incorrect. Lanugo (fine hair) tends to decrease as the pregnancy progresses towards term. In post-term newborns, lanugo is usually sparse or absent.
- D. Heel to ear maneuverability
- Incorrect. Heel-to-ear maneuverability, which assesses the flexibility of the newborn, is more characteristic of preterm infants. Post-term infants may show decreased flexibility due to increased muscle tone and less room in the uterus.
Correct Answers: A. Moro reflex
So, the expected finding for a post-term newborn immediately following delivery is the presence of the Moro reflex.
