Answer to Question 1

ANS: C
Adequate central nervous system function is needed to ensure stable ventilatory drive, adequate secretion clearance (cough and deep breathing), and protection of the airway (gag reflex and swallow). In addition, level of consciousness, dyspnea, anxiety, depression, and motivation can affect weaning success. The patient ideally is awake and alert, free of seizures, and able to follow instructions.

Answer to Question 2

ANS: B
Level of consciousness is affected by the use of narcotic, sedative, and analgesic drugs.
