Answer to Question 1

Ans: D
Pursed-lip breathing can help clients with dyspnea and feelings of panic gain control of their respirations. This exercise trains the muscles to prolong expiration, increasing airway pressure during expiration, and reducing the amount of airway trapping and resistance.

Answer to Question 2

Ans: C
After insertion, the chest tube is secured with a suture and tape, covered with an airtight dressing, and usually attached to a closed water-seal drainage system that prevents air from reentering the pleural space.
