question 4 (mandatory) (2 points)
listen
a 6 - year old boy puts the contents of a bag of peanuts in his mouth and then takes a deep breath with the idea of blowing the peanuts out all over his sister. he aspirates a peanut during this maneuver. one day later he develops dyspnea. on physical exam there are decreased breath sounds on auscultation over the right lower lung posteriorly. chest ct scan shows an oval area of density in the right lower lobe. gram stain of sputum is normal. which of the following complications has this child most likely developed?
contraction atelectasis
acute bronchiolitis
resorption atelectasis
bronchopneumonia

Explanation:

1. Analyze the case: A child aspirated a peanut, then developed dyspnea, decreased breath sounds, and a density on CT.
2. Recall atelectasis types: Resorption atelectasis occurs when an airway is obstructed (like a peanut), preventing air from reaching alveoli, leading to alveolar collapse.
3. Eliminate other options:

• Contraction atelectasis is due to fibrosis/scarring (not acute obstruction).
• Acute bronchiolitis is viral (no obstruction history here).
• Bronchopneumonia has inflammatory exudate (sputum Gram stain is normal, so no infection signs yet).

So the obstruction from the peanut causes resorption atelectasis.

Answer:

Resorption Atelectasis
