Final answer:
Daily chest physiotherapy for a client with cystic fibrosis aims to mobilize secretions in the airways to facilitate the removal of thick, dry mucus, which helps in preventing lung infections.
Step-by-step explanation:
The purpose of daily chest physiotherapy for a client with cystic fibrosis is b. to mobilize secretions in the airways. Cystic fibrosis causes thick, dry mucus to accumulate in the lungs, which can interfere with the body's ability to clear out pathogens and can lead to infections.
Treatment includes measures to thin the mucus, promoting its removal from the airways through coughing. Chest physiotherapy helps in loosening the mucus so that it can be coughed out, which is vital for pulmonary hygiene in cystic fibrosis patients. This process prevents the build-up of mucus in the lungs, which can cause blockages and lead to respiratory infections.
