Answer to Question 1

ANS: C
Varying the size of this orifice varies the inspiratory load, as do changes in the patient's inspira-tory flow. During expiration, gas flows unimpeded out the one-way exhalation valve. Other types of devices are also available. One model replaces the variable size orifice with an adjustable spring-loaded valve. This ensures a relatively constant load regardless of how fast or slowly the patient breathes.

Answer to Question 2

ANS: C
Arm ergometers or rowing machines are available for this purpose; however, simple calisthenics using either a broomstick or free weights (by prescription and with training) are a satisfactory al-ternative.
