Answer to Question 1

ANS: D
Most postoperative patients also have problems coughing effectively because of their reduced ability to take deep breaths.

Answer to Question 2

ANS: D
An ineffective cough impairs normal clearance mechanisms and increases the likelihood of re-tained secretions and gas absorption atelectasis in the patient with excessive mucus production. For this reason, patients with a history of lung disease that causes increased mucus production (e.g., chronic bronchitis) are most prone to develop complications in the postoperative period. Similarly, a significant history of cigarette smoking should alert the respiratory therapist to the high risk for respiratory complications with surgery.
