Answer to Question 1

ANS: A
The upper inflection point indicates a point at which large numbers of alveoli are becoming over-inflated.

Answer to Question 2

ANS: A
Airway resistance can be estimated for a ventilated patient using transairway pressure (PTA). When peak inspiratory pressure (PIP) increases and plateau pressure (Pplateau) remains relatively unchanged, there is an increase in PTA. An increased Pplateau and a stable PIP indicate a decrease in static compliance.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
