1. A preterm neonate born at 28 weeks' gestation develops respiratory
distress immediately after birth. The infant has tachypnea, nasal flaring,
intercostal retractions, and grunting. Oxygen saturation remains low
despite supplemental oxygen. Which pathophysiologic mechanism most
directly explains this infant's respiratory distress syndrome (RDS)?
A. Excessive pulmonary surfactant production causing alveolar collapse
B. Insufficient surfactant causing increased alveolar surface tension and
atelectasis
C. Increased pulmonary blood flow causing pulmonary edema
D. Premature closure of the ductus arteriosus causing right-to-left
shunting
Answer: B. Insufficient surfactant causing increased alveolar
surface tension and atelectasis
Rationale: Respiratory distress syndrome in premature neonates
primarily results from inadequate pulmonary surfactant production by
immature type II pneumocytes. Reduced surfactant increases alveolar
surface tension, promoting alveolar collapse, decreased lung
compliance, impaired gas exchange, and increasing oxygen
requirements. The risk is particularly high with decreasing gestational
age.

,2. A 30-week premature infant receiving continuous positive airway
pressure (CPAP) suddenly develops increased oxygen requirements,
asymmetric chest movement, diminished breath sounds on the right side,
and bradycardia. Which complication should the nurse suspect first?
A. Pulmonary edema
B. Pneumothorax
C. Necrotizing enterocolitis
D. Patent ductus arteriosus
Answer: B. Pneumothorax
Rationale: A sudden increase in oxygen requirement accompanied by
asymmetric chest movement, unilateral diminished breath sounds, and
cardiovascular deterioration strongly suggests pneumothorax.
Positive-pressure respiratory support increases the risk of air-leak
syndromes. Rapid recognition is critical because a tension
pneumothorax can compromise venous return and cause
cardiovascular collapse.
3. A neonate is receiving phototherapy for unconjugated
hyperbilirubinemia. Which nursing intervention is most appropriate?
A. Keep the infant fully clothed to prevent heat loss
B. Cover the infant's eyes and expose as much skin as safely possible
C. Apply lotion to the infant's skin every hour
D. Discontinue feeding during phototherapy
Answer: B. Cover the infant's eyes and expose as much skin as
safely possible
Rationale: Phototherapy converts bilirubin into water-soluble
photoisomers that can be eliminated without hepatic conjugation.
Maximizing exposed skin increases treatment effectiveness, while
appropriate eye protection protects the retina. Temperature and
2
,hydration should be monitored closely, and feeding should generally
continue because adequate intake promotes stooling and bilirubin
elimination.
4. A term neonate develops jaundice at 8 hours of life. Which
interpretation by the nurse is most appropriate?
A. This is expected physiologic jaundice
B. This is most likely breast milk jaundice
C. Jaundice appearing this early is pathologic until proven otherwise
D. This is expected because bilirubin peaks during the first 12 hours
Answer: C. This is pathologic until proven otherwise
Rationale: Jaundice appearing within the first 24 hours of life is
concerning for pathologic hyperbilirubinemia. Potential causes
include hemolysis, blood-group incompatibility, infection, or other
disorders causing excessive bilirubin production. Physiologic jaundice
generally becomes apparent after the first day of life.
5. A newborn of a mother with diabetes is being monitored during the
first hours after birth. Which complication requires particularly close
surveillance?
A. Hypercalcemia
B. Hypoglycemia
C. Hypernatremia
D. Respiratory alkalosis
Answer: B. Hypoglycemia
Rationale: Maternal hyperglycemia stimulates fetal pancreatic beta
cells to produce increased insulin. After delivery, the maternal glucose
supply abruptly stops while neonatal hyperinsulinemia may persist,
3
, resulting in hypoglycemia. At-risk infants require appropriate glucose
monitoring and early feeding or treatment according to clinical status
and institutional protocols.
6. A newborn's blood glucose is low, and the infant is jittery, irritable,
and feeding poorly. What is the nurse's priority?
A. Delay intervention until another glucose measurement is obtained
tomorrow
B. Recognize the symptoms as potentially related to hypoglycemia and
initiate appropriate treatment
C. Place the infant under phototherapy
D. Restrict oral intake
Answer: B. Recognize the symptoms as potentially related to
hypoglycemia and initiate appropriate treatment
Rationale: Neonatal hypoglycemia may cause jitteriness, lethargy,
poor feeding, temperature instability, apnea, seizures, and neurologic
injury. A symptomatic infant requires prompt evaluation and
treatment rather than prolonged observation. Management depends on
glucose concentration, symptoms, gestational age, feeding ability, and
institutional protocol.
7. A newborn is receiving intravenous calcium gluconate. Which
assessment finding requires immediate attention?
A. Mild sleepiness after feeding
B. Bradycardia during administration
C. Urination after feeding
D. Brief sneezing
Answer: B. Bradycardia during administration
