Patients with acute severe asthma requiring mechanical ventilation are difficult to manage be-cause of which of the following?
a. Diaphragmatic paralysis
b. Increased lung compliance
c. Decreased airway resistance

ANS: D
Increased airway resistance from bronchospasm, increased secretions, and mucosal edema cause air trapping, which can cause uneven hyperexpansion of various lung units. This can cause rupture or compress other areas of the lungs leading to pneumothorax, pneumomediastinum, subcutane-ous emphysema, and other forms of barotrauma.
