The Preterm Newborn

++
++
++

Neonates born prematurely compared with term newborns have higher associated rates of which of the following?

++
++
++

a. Congenital malformations

++
++

b. Necrotizing enterocolitis

++
++

c. Bronchopulmonary dysplasia

++
++

d. All of the above

++
++ ++
++
++

Following birth, neonatal alveoli must rapidly clear amnionic fluid and remain expanded to permit gas exchange. All EXCEPT which of the following assist this transition?

++
++
++

a. Lymphatic absorption of amnionic fluid

++
++

b. Pulmonary vasculature absorption of amnionic fluid

++
++

c. Chest compression by the vaginal walls during delivery

++
++

d. Surfactant-related increases in alveolar surface tension

++
++ ++
++
++

Clinical signs of respiratory distress syndrome include all EXCEPT which of the following?

++
++
++

a. Grunting

++
++

b. Hypertension

++
++

c. Respiratory acidosis

++
++

d. Chest wall retraction during inspiration

++
++ ++
++
++

A 30-week newborn displays grunting, nasal flaring, chest retractions, and diminished oxygen saturation. Chest radiography shows a moderate left pneumothorax, seen here. In general, all EXCEPT which of the following should be included in the initial differential diagnosis of respiratory distress in a preterm neonate?

++
++
++
++

a. Sepsis

++
++

b. Diaphragmatic hernia

++
++

c. Bronchopulmonary dysplasia

++
++

d. Persistent fetal circulation

++
++ ++
++
++

With respiratory distress syndrome, as shown here, a chest radiograph will most likely display which of the following?

++
++
++
++

a. Perihilar infiltrate

++
++

b. Diffuse reticulogranular infiltrate

++
++

c. Increased central bronchovascular markings

++
++

d. Honeycomb pattern with or without air-fluid levels

++
++ ++
++
++

Once diagnosed, respiratory distress syndrome is preferably treated with which of the following?

++
++
++

a. Intravenous ...
