Answer to Question 1

ANS: B
Postural drainage is most effective in conditions characterized by excessive sputum production (>25 to 30 ml/day). For maximum effect, head-down positions should exceed 25 degrees below horizontal. Postural drainage is not likely to succeed unless and until adequate systemic and air-way hydration is ensured.

Answer to Question 2

ANS: B
There are five general approaches to airway clearance therapy, which can be used alone or in combination. These approaches include (1) postural drainage therapy (including turning, percus-sion, and vibration), (2) coughing and related expulsion techniques, (3) positive airway pressure (PAP) adjuncts (positive expiratory pressure PEP, continuous PAP CPAP, expiratory PAP EPAP), (4) high-frequency compression/oscillation methods, and (5) mobilization and exercise.
