Correct Answer is A

Explanation

A) Correct. Postural drainage and chest percussion help mobilize and remove thick, sticky mucus from the airways, which is crucial in managing CF.

B) Incorrect. While bronchodilators may be used, they are not the primary therapy for managing CF. Airway clearance techniques like postural drainage are more important.

C) Incorrect. Oxygen therapy should be administered as needed, but it is not required around the clock for all CF patients.

D) Incorrect. Deep breathing exercises should be encouraged regularly, not just during illness, to maintain airway clearance and lung function.

A. Wheezing and chest pain B. Chronic cough with thick mucus production C. Blood in the urine D. Digestive discomfort and diarrhea

Correct Answer is B

Explanation

A) Incorrect. Wheezing and chest pain can occur in CF, but a chronic cough with thick mucus production is often one of the earliest respiratory symptoms.

B) Correct. A chronic cough with thick, sticky mucus is a hallmark symptom of CF due to the accumulation of mucus in the respiratory tract.

C) Incorrect. Blood in the urine is not a common early sign of CF; it may indicate other issues.

D) Incorrect. Digestive discomfort and diarrhea are more related to CF's impact on the gastrointestinal system, rather than being early respiratory symptoms.
