Question 1

Which reflex, elicited by stroking the lateral sole of the foot, results in hyperextension and fanning of the toes in newborns and is considered normal?

Accepted Answer

Babinski reflex

Answer

The Babinski reflex (upgoing plantar reflex) is normal in newborns and infants up to approximately 12 months due to immature corticospinal tracts.

Question 2

A newborn is noted to have a cephalohematoma. Which of the following accurately describes this finding?

Accepted Answer

Blood accumulation below the periosteum, confined to one cranial bone, does not cross suture lines

Answer

A cephalohematoma is subperiosteal bleeding confined by periosteal attachments at suture lines, causing a unilateral, well-demarcated swelling that resolves over weeks.

Question 3

The nurse is evaluating a newborn for hypoglycemia. Which clinical manifestation warrants immediate glucose screening?

Accepted Answer

Jitteriness and high-pitched cry

Answer

Jitteriness, high-pitched cry, lethargy, and poor feeding are classic signs of neonatal hypoglycemia and require immediate point-of-care glucose testing.

Question 4

When auscultating a newborn's heart, the nurse detects a harsh systolic murmur at the left sternal border at 2 hours of age. The most appropriate initial action is to:

Accepted Answer

Document findings and reassess at 24 hours, as murmurs may reflect transitional circulation

Answer

Transient murmurs are common in the first hours of life as transitional circulation closes (ductus arteriosus, foramen ovale); reassessment and provider notification are appropriate first steps.

Question 5

A newborn's glucose level is 38 mg/dL at 1 hour of life. The infant is alert and breastfeeding vigorously. The nurse should:

Accepted Answer

Encourage continued frequent breastfeeding and recheck glucose in 1 hour

Answer

An asymptomatic newborn with a glucose of 36–45 mg/dL should receive oral feeding as the first intervention, followed by repeat glucose check within 30–60 minutes.
