The Collection of Mucus in the Lower Airways is Most

Question

The collection of mucus in the lower airways is most likely to cause
A) laryngospasm.
B) pneumothorax.
C) atelectasis.
D) pharyngitis.

Accepted Answer

The collection of mucus in the lower airways can cause atelectasis, which is the collapse of a part or all of the lung due to the obstruction of the air passages by mucus or other material. Atelectasis can lead to impaired gas exchange, decreased lung function, and increased risk of infection. Laryngospasm (A) is a sudden spasm of the vocal cords that can cause difficulty breathing, while pneumothorax (B) is the presence of air in the pleural cavity that can cause lung collapse. Pharyngitis (D) is inflammation of the pharynx, which is not directly related to mucus collection in the lower airways.
