Answer to Question 1

ANS: C
Proprioceptors in muscles, tendons, and joints, as well as pain receptors in muscles and skin, send stimulatory signals to the medullary respiratory center. Such stimuli increase medullary inspirato-ry activity and cause hyperpnea. For this reason, moving the limbs, slapping or splashing cold water on the skin, and other painful stimuli stimulate ventilation in patients with respiratory de-pression.

Answer to Question 2

ANS: C
Interviewing furnishes unique information because it provides the patient's perspective. It serves the following three related purposes: (1) to establish a rapport between clinician and patient, (2) to obtain essential diagnostic information, and (3) to help monitor changes in the patient's symp-toms and response to therapy.
