D. Ballard score indicating low gestational maturity
A 900-gram male infant is born extremely premature. On physical examination, he has gelatinous, translucent skin, but the pinna appears formed and firm with instant recoil, which is scored as 4 in the Ballard score, suggesting maturity. Which of the following physical findings is more consistent with prematurity?
A. Well-formed, firm pinna with instant recoil
B. Gelatinous, translucent skin
C. Presence of lanugo on the face and back
D. Absence of a breastbud
A newborn with an estimated gestational age of 42 weeks is noted to be stained with meconium. Tracheal intubation reveals meconium in the hypopharynx and below the vocal cords. The infant develops respiratory distress, and a chest X-ray is obtained.
Which of the following is the most likely radiographic finding?
A. Decreased lung volume
B. Reticulogranular pattern
C. Pleural effusion
D. Patchy infiltrates with areas of hyperinflation
A 32-week preterm baby is born to a mother with eclampsia who was given magnesium sulfate. The baby was resuscitated and transferred to the NICU. At 12 hours of life, the baby develops hypotonia, lethargy, constricted pupils, and experiences two seizures.
What is the most likely diagnosis?
A. Hypoglycemia
B. Benign neonatal seizure
C. Intraventricular hemorrhage (IVH)
D. Hypoxic-ischemic encephalopathy (HIE)
A newborn presents with respiratory distress, difficulty feeding, and frothy salivation. The baby has a normal, vigorous cry that temporarily relieves the distress and shows no stridor. On physical exam, there are no other obvious abnormalities.
What is the most likely diagnosis?
A. Choanal atresia
B. Laryngomalacia
C. Tracheoesophageal fistula (TEF)
D. Transient tachypnea of the newborn (TTN)
A newborn presents with respiratory distress, difficulty feeding, and frothy salivation. The distress is relieved by a vigorous cry, and there is no stridor. Physical exam is otherwise unremarkable.
Given the suspicion for tracheoesophageal fistula (TEF), what is the most helpful initial diagnostic maneuver?
A. Attempt to pass a nasogastric catheter into the stomach
B. Administer a feeding trial to observe tolerance
C. Perform direct laryngoscopy
D. Obtain pulse oximetry at rest and while feeding
A term newborn presents with bilious vomiting shortly after birth. The abdomen is slightly distended, and facial features suggestive of Down syndrome are noted. The infant has passed normal meconium, and the pregnancy was complicated by polyhydramnios.
What is the most likely diagnosis?
A. Duodenal atresia
B. Meconium ileus
C. Midgut volvulus
D. Hirschsprung disease
A previously healthy 5-day-old male infant was born at home and presents with bruising, melena, and bloody stools. Pregnancy, delivery, and postnatal course were unremarkable. He is breastfeeding well, and physical exam reveals multiple large bruises but is otherwise normal.
