Answer to Question 1

ANS: B
For this reason, a multiple-stage reducing valve should be considered only if minimal fluctuations in pressure or flow are critical factors, as in research activities. For routine hospital work, sin-gle-stage reducing valves are satisfactory.

Answer to Question 2

ANS: D
A flow restrictor is a fixed-orifice, constant-pressure flowmeter device.

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).

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.
