Q

A 38 5/7-week estimated gestational age girl is examined in the special care nursery at 3 hours of life who developed tachypnea and mild respiratory distress 10 minutes ago. Mom’s prenatal history was uncomplicated and her prenatal labs were not concerning for infection. She required no ventilatory support at delivery. The baby has the following vital signs: temperature 36.9°C (98.4°F), heart rate 136/min, respiratory rate 83/min, blood pressure 75/42, and oxygen saturation 93%. She has some shallow breathing with mild subcostal retractions and no grunting or nasal flaring, and she is otherwise well perfused with good femoral and brachial pulses. A chest X-ray reveals a flat diaphragm, prominent vascular markings, and fluid in the interlobar fissures. No granular densities or opacities/air brochograms are seen.

What is the next step in management of this patient?

A. Continuous positive airway pressure (CPAP)
B. O2 via nasal cannula
C. Surfactant
D. Conservative management with orogastric tube feeds or IV fluids for nutrition
E. Intubation

Q

One hour after delivery, a 1 077-g (2-lb 6-oz) newborn is in respiratory distress. She was born at 28 weeks’ gestation following an otherwise uncomplicated pregnancy and delivery. The mother received routine prenatal care and intrapartum antibiotic prophylaxis. Apgar scores were 5 and 8 at 1 and 5 minutes, respectively. On initial examination, the newborn appeared pink and was active. Currently, her temperature is 36.4°C (97.5°F), pulse is 160/mm, respirations are 60/mm and shallow, and blood pressure is 68/44 mm Hg. Examination shows grunting, nasal flaring, and intercostal retractions A chest x-ray shows a granular appearance of the parenchyma with air bronchograms. Which of the following is the most likely diagnosis?

Meconium aspiration pneumonia
Respiratory distress syndrome of the newborn
Streptococcus agalactiae (group B) infection

Q

A 3-week-old male infant is brought into the pediatrician for several episodes of cyanotic lips during feeding. His mother notes he becomes severely agitated during his feeds and looks as though he is holding his breath. Physical examination reveals a calm male infant sleeping in his mother’s arms. Cardiac examination reveals a crescendo-decrescendo murmur best heard at the left upper sternal border and a single S2. Lungs are clear to auscultation bilaterally, with no rales or rhonchi noted. Abdomen is soft, nondistended, with normoactive bowel sounds. Skin examination reveals no signs of cyanosis. A chest x-ray is performed in the office and reveals an elongated apex of the heart

Q 
A previously healthy 7 weeks-old boy is brought to the physician because of a 3-day history of vomiting. His mother says that he has been taking his cow milk-based formula well but vomits after every feeding. The vomiting has been increasing in amount and force; the vomitus appears to be nonbloody, nonbilious undigested formula. He appears mildly dehydrated. He is at the 25th percentile for length and 10th percentile for weight. Vital signs are within normal limits. The remainder of the examination shows no abnormalities.
Serum studies show:
Na+		130 mEq/L
K+		                3.0 mEq/L (low)
Cl-		85 mEq/L  (low)
HCO3- 		34 mEq/L  (high)
A

Pyloric Stenosis

46
Q

A 1-day-old 2460-g (5-Ib 7-oz) boy has progressive abdominal distention. He was born at 38 weeks’ gestation following an uncomplicated pregnancy and delivery Since birth, he has had two episodes of bilious vomiting after feedings and has not yet passed meconium. The abdomen is distended and firm with visible loops of bowel. There are no external hernias, and the anus is patent. X-rays of the abdomen show several dilated loops of bowel with air-fluid levels A barium enema shows an abrupt change in caliber at the midsigmoid colon from normal-sized bowel to dilated bowel proximally. Immediately after the barium enema, he has a large, explosive bowel movement.

A

Abnormal caudal migration of ganglion cells

47
Q

A nurse calls the attending physician to examine an infant born at 28 weeks in the NICU now one day of life . She mentions that the baby had been
voiding and stooling appropriately but today has been having bilious residuals
and
began experiencing some short episodes of apnea. On exam, the baby has increased abdominal girth and a distended abdomen with hypoactive bowel sounds.
Bloody stools are present in the diaper. Pulses are slightly diminished peripherally.
An abdominal film reveals dilated loops of bowel, thickening around the right colon, and pneumatosis.
