Answer to Question 1

ANS: C
A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: ARDS and ALI are parenchymal lung injuries that have specific diagnostic criteria. Both have acute onset and bilateral infiltrates on chest radiography. Neither injury reflects cardiogenic edema. The PCWP will therefore be less than 18 mm Hg, and the Pao2/Fio2 ratios will be less than 200 for ARDS and less than 300 for ALI.
D. Incorrect response: See explanation C

Answer to Question 2

ANS: D
A. Incorrect response: See explanation D.
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response: Although the disease processes involved in parenchymal lung injury are different, pathophysiologic similarities exist. All parenchymal lung diseases have varying degrees of interstitial edema, alveolar edema, surfactant dysfunction, and decreased pulmonary 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).
