"CF results from a dominant genetic mutation inherited from one parent."

"CF occurs due to the presence of two dominant genetic mutations."

"CF is caused by a recessive genetic mutation inherited from both parents."

"CF is a non-genetic condition caused by environmental factors."

B) Incorrect. CF is not caused by dominant genetic mutations.

C) Correct. CF results from inheriting two recessive genetic mutations, one from each parent, leading to defective CFTR protein function.

Correct Answer is B

Explanation

A) Incorrect. Clubbed fingers in CF can be more than a cosmetic concern and may indicate underlying medical issues.

B) Correct. Clubbing of the fingers can be associated with advanced lung disease or reduced oxygen levels in CF.

C) Incorrect. Clubbing is not related to excessive sodium intake in CF patients.

D) Incorrect. While CF can affect the digestive system, clubbing of the fingers is primarily associated with respiratory issues.

A. Initiation of long-term oxygen therapy B. Administration of bronchodilators and corticosteroids C. Surgical lung transplantation D. Recommending bed rest and minimal physical activity

Correct Answer is B

Explanation

A) Incorrect. Long-term oxygen therapy is typically reserved for individuals with chronic hypoxemia and is not the primary treatment for a pulmonary exacerbation.

B) Correct. Bronchodilators and corticosteroids are commonly used to manage pulmonary exacerbations in CF by reducing airway inflammation and improving airflow.

C) Incorrect. Surgical lung transplantation is considered in severe cases of CF with irreversible lung damage but is not typically the first-line treatment for a pulmonary exacerbation.

D) Incorrect. Bed rest and minimal physical activity are not recommended as the primary treatment for pulmonary exacerbations; maintaining mobility and airway clearance techniques are important.
