Question 1

A mother asks why her 2-day-old infant's eyes look yellowish. The nurse explains that neonatal jaundice at this age is most likely caused by:

Accepted Answer

Normal breakdown of fetal hemoglobin exceeding the immature liver's conjugation capacity

Answer

Physiologic jaundice results from the accelerated breakdown of fetal RBCs and relative hepatic immaturity that limits bilirubin conjugation and excretion.

Question 2

A newborn's initial Apgar score is 5 at 1 minute. The nurse's priority action is to:

Accepted Answer

Provide tactile stimulation, position the airway, and administer supplemental oxygen if needed

Answer

An Apgar score of 4–6 indicates moderate depression; the nurse should initiate basic resuscitative steps (stimulation, airway positioning, supplemental oxygen) and reassess at 5 minutes.

Question 3

During circumcision aftercare teaching, the nurse instructs parents to apply petroleum jelly to the site with each diaper change primarily to:

Accepted Answer

Prevent the healing tissue from adhering to the diaper

Answer

Petroleum jelly prevents the raw tissue of the circumcision site from sticking to the diaper, reducing trauma and discomfort during healing.

Question 4

The nurse notes a newborn has positional (postural) talipes equinovarus (clubfoot). Which intervention is appropriate for the nurse to initiate?

Accepted Answer

Perform passive range-of-motion exercises and refer to orthopedics

Answer

Positional clubfoot responds to passive stretching and orthopedic referral; early intervention with the Ponseti method is the standard of care.

Question 5

When preparing a newborn for a heel stick glucose test, which technique reduces pain most effectively?

Accepted Answer

Administer 24% sucrose solution orally 2 minutes before the procedure while the infant sucks on a pacifier

Answer

Sweet oral solutions (24% sucrose) combined with non-nutritive sucking activate endogenous opioid pathways and are the most evidence-based non-pharmacologic neonatal analgesic for minor procedures.
