A client with cystic fibrosis (CF) asks the nurse about the impact of CF on the respiratory system. What response by the nurse accurately describes the respiratory complications associated with CF?

"CF primarily affects the upper respiratory tract, leading to frequent sinus infections."

"CF causes inflammation and obstruction of the airways, leading to chronic lung infections and lung damage."

"CF typically results in enlarged tonsils and adenoids, which can affect breathing."

"CF mainly affects the bronchial tubes, causing chronic cough but not lung infections."

Answer and Explanation

The Correct Answer is B

A) Incorrect. CF primarily affects the lower respiratory tract, particularly the bronchi and bronchioles, rather than the upper respiratory tract.

B) Correct. CF leads to thickened mucus in the airways, which can cause inflammation, recurrent infections, and progressive lung damage.

C) Incorrect. Enlarged tonsils and adenoids are not a typical manifestation of CF-related respiratory complications.

D) Incorrect. CF affects both the bronchial tubes and the entire respiratory system, often leading to chronic lung infections.

Correct Answer is C

Explanation

A) Incorrect. PERT is not primarily used to control blood sugar levels; it is used to improve nutrient absorption.

B) Incorrect. While CF management aims to improve lung function, PERT is specifically used to address pancreatic insufficiency and digestive issues.

C) Correct. The primary purpose of PERT in CF management is to replace the missing digestive enzymes and aid in the digestion of fats and nutrients.

D) Incorrect. PERT does not increase mucus production in the airways; it is focused on the digestive system.

A. Coughing forcefully B. Controlled breathing exercises C. Huff coughing D. Exercising vigorously

Correct Answer is C

Explanation

A) Incorrect. While coughing is important, huff coughing is a more effective and less strenuous airway clearance technique for CF patients.

B) Incorrect. Controlled breathing exercises may help with relaxation but are not the primary airway clearance technique.

C) Correct. Huff coughing is a technique where the client takes a deep breath and forcefully exhales in short bursts, helping to move mucus from the airways.

D) Incorrect. Vigorous exercise is beneficial for CF patients but should not replace specific airway clearance techniques.
