Answer to Question 1

C
An inspiratory sawtooth pattern on the flow-volume loop is associated with obstructive sleep apnea. The sawtooth pattern is caused by loose tissues in the throat moving during the rapid inspiration. Patients with COPD have a distinctively slow expiratory flow pattern. A patient with laryngeal edema (epiglottitis) will often have a distinctive inspiratory stridor sound.

Answer to Question 2

C
A recurrent cough, recurrent chest tightness, and recurrent wheeze are symptoms associated with asthma.
