A nurse is educating a client with cystic fibrosis (CF) about airway clearance techniques. Which of the following airway clearance methods involves the use of a mechanical device to deliver high-frequency chest wall oscillations?

Postural drainage

Autogenic drainage

Positive expiratory pressure (PEP) therapy

High-frequency chest wall oscillation (HFCWO)

Answer and Explanation

The Correct Answer is D

A) Incorrect. Postural drainage involves positioning the body to help drain mucus but does not use a mechanical device.

B) Incorrect. Autogenic drainage is a technique that involves controlled breathing and airflow, not a mechanical device.

C) Incorrect. PEP therapy uses a device to provide positive pressure during exhalation but is different from HFCWO.

D) Correct. High-frequency chest wall oscillation (HFCWO) involves using a mechanical device to deliver oscillations to the chest wall, helping to mobilize and clear mucus from the airways.
