A nurse is caring for a pediatric client with cystic fibrosis. Which respiratory therapy technique should the nurse prioritize to help manage the client's condition?

Postural drainage and chest percussion

Administering bronchodilators as needed

Providing oxygen therapy around the clock

Encouraging deep breathing exercises only during illness

Answer and Explanation

The Correct Answer is A

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.

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. "The CFTR protein regulates sodium absorption in the kidneys." B. "The CFTR protein facilitates chloride secretion in the gastrointestinal tract." C. "The CFTR protein controls the production of red blood cells in the bone marrow." D. "The CFTR protein regulates mucus production and the movement of chloride ions in the respiratory and digestive systems."

Correct Answer is D

Explanation

A) Incorrect. The CFTR protein primarily functions in the respiratory and digestive systems, not the kidneys.

B) Incorrect. While CFTR plays a role in chloride secretion, its primary role is related to mucus production and chloride ion movement in the respiratory and digestive systems.

C) Incorrect. The CFTR protein is not involved in the production of red blood cells.

D) Correct. The CFTR protein is responsible for regulating mucus consistency and chloride ion transport in the respiratory and digestive systems.
