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.
