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.

A. Dry, nonproductive cough B. Decreased breath sounds C. Hematuria D. Rapid weight gain

Correct Answer is B

Explanation

A) Incorrect. In advanced CF-related lung disease, a chronic, productive cough with thick mucus production is more common than a dry, nonproductive cough.

B) Correct. Decreased breath sounds may occur in clients with advanced CF-related lung disease due to airway obstruction and lung damage.

C) Incorrect. Hematuria is not a typical respiratory symptom of CF.

D) Incorrect. Rapid weight gain is not associated with advanced CF-related lung disease; individuals with advanced CF often experience weight loss and malnutrition.
