Question 207 · LEK · Respiratory system
Physical examination of a 4-month-old infant revealed signs of dyspnea, tachypnea 75/ min and diffused rales on lung auscultation. The child was born at 28 hbd, with the birth weight of 820 g. Oxygen therapy was necessary for the first two months of life. Body temperature was 36.8 °C, CRP 1 mg/L. A chest X-ray showed diffused small infiltrations within the lungs. The most probable diagnosis is:
- A. alpha-1-antitrypsin deficiency.
- B. bronchiolitis.
- C. cystic fibrosis.
- D. pneumonitis.
- E. bronchopulmonary dysplasia.
Hint
Link extreme prematurity and prolonged early oxygen dependence with a chronic lung disease of preterm infants rather than an acute infection.
