Answer to Question 1

ANS: A
CI = /BSA.
CI = 5.0 mL/min 2.9 m2.
CI = 1.72 mL/min/m2.

Answer to Question 2

ANS: A
A resistive (or resistance) transducer consists of a thin metal bellows attached to four wires, forming a Wheatstone bridge. The variable capacitance transducer has a flexible diaphragm to sense pressure changes, but it is linked to an electrode. A variable inductance transducer consists of a stainless steel diaphragm attached to a soft iron core positioned between two coils.
