Caregivers have just received discharge instructions for their son, who was newly diagnosed with cystic fibrosis. The father confirms understanding of the primary goal of chest physiotherapy (CP) by stating:(A) CP allow the lung to re-expand(B) CP allows for deeper breathing(C) CP prevents hospitalization(D) CP increase the resistance to respiratory infection(E) CP helps mobilize and expectorate secretion.

Option E) CP helps mobilize and expectorate secretion.

Explanation:

Cystic fibrosis is a genetic condition characterized by the presence of abnormally viscous mucus, leading to respiratory problems such as breathing and feeding at times.

Thus, Caregivers recommend chest physiotherapy to help patients relax the airways, aerate the lungs, and cough up fluid from the lungs.

(E) CP helps mobilize and expectorate secretion.

Explanation:

Cystic fibrosis is is a hereditary disease characterized by obstruction of the respiratory tract which leads to bacteria infection of the airways. In cystic fibrosis, the thin layer of mucus which coats the internal surfaces of the lungs is abnormally thick thereby obstructing the flow of air and providing a haven for pathogenic bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa.

Chest physiotherapy helps to loosen the thick layer of mucus that coats the surfaces of the lungs so that it can be removed by coughing. Chest physiotherapy breaks down the thick mucus so that it can be expectorated.
