A 3-year-old girl is brought to the emergency department by her parents with sudden onset shortness of breath. They tell the emergency physician that their daughter was lying on the bed watching television when she suddenly began gasping for air. They observed a bowl of peanuts lying next to her when they grabbed her up and brought her to the emergency department. Her respirations are 25/min, the pulse is 100/min and the blood pressure is 90/65 mm Hg. The physical findings as of now are apparently normal. She is started on oxygen and is sent in for a chest X-ray. Based on her history and physical exam findings, the cause of her current symptoms would be seen on the X-ray at which of the following sites?
AThe superior segment of the right lower lobe
BThe posterior segment of the right lower lobe
CThe lingula of the left upper lobe
DThe apical segment of the right upper lobe
EThe apical segment of the left upper lobe
A 3-year-old boy is brought to a respiratory specialist. The family physician referred the child because of recurrent respiratory infections over the past 2 years. Chest X-rays showed a lesion of < 2 cm that includes glands and cysts in the upper lobe of the right lung. Diseases affecting the immune system were investigated and ruled out. No family history of any pulmonary disease or congenital malformations exists. He was born at full term via a normal vaginal delivery with an APGAR score of 10. Which of the following should be highly considered for effective management of this child’s condition?
ALobectomy
BAntibiotics
CObservation
DBronchoscopy
EPneumonectomy
Five weeks after delivery, a 1350-g (3-lb 0-oz) male newborn has respiratory distress. He was born at 26 weeks' gestation. He required intubation and mechanical ventilation for a month following delivery and has been on noninvasive pressure ventilation for 5 days. His temperature is 36.8°C (98.2°F), pulse is 148/min, respirations are 63/min, and blood pressure is 60/32 mm Hg. Pulse oximetry on 40% oxygen shows an oxygen saturation of 91%. Examination shows moderate intercostal and subcostal retractions. Scattered crackles are heard in the thorax. An x-ray of the chest shows diffuse granular densities and basal atelectasis. Which of the following is the most likely diagnosis?
ABronchopulmonary dysplasia
BTracheomalacia
CBronchiolitis obliterans
DInterstitial emphysema
EPneumonia
