Question 10 :

A nurse is discussing the pathophysiological consequences of cystic fibrosis (CF) with a client. Which of the following best describes how CF affects the respiratory system?

A "CF primarily causes airway constriction due to inflammation."

Incorrect. While inflammation can be a consequence of CF, it is not the primary cause of airway constriction.

B "In CF, the thickened mucus in the airways leads to chronic inflammation, infections, and lung damage."

Correct. In CF, thickened mucus accumulates in the airways, leading to chronic inflammation, recurrent infections, and progressive lung damage.

C "CF results in the overproduction of surfactant, causing respiratory distress."

Incorrect. CF does not result in the overproduction of surfactant, which is a substance that helps reduce surface tension in the lungs.

D "The CFTR protein in the lungs fails to produce enough oxygen for normal breathing."

Incorrect. The CFTR protein does not produce oxygen but rather regulates chloride ion and water transport in the lungs
