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 C

Explanation

A) Incorrect. CF primarily affects the pancreas and small intestine, not the stomach.

B) Incorrect. While liver complications can occur in some individuals with CF, such as liver disease or cirrhosis, it is not a primary manifestation of the disease.

C) Correct. CF often results in thickened mucus obstructing the pancreatic ducts, causing pancreatic insufficiency and malabsorption of essential nutrients.

D) Incorrect. CF primarily affects the pancreas and small intestine rather than the large intestine, and chronic constipation is not a typical symptom of CF.

A. "CF is caused by a single gene mutation, which can be inherited from one parent." B. "CF results from a combination of genetic and environmental factors." C. "CF occurs due to an X-linked genetic mutation passed from mother to daughter." D. "CF is primarily caused by exposure to respiratory pathogens during infancy."

Correct Answer is A

Explanation

A) Correct. CF is primarily caused by mutations in a single gene, the CFTR gene, and it can be inherited from one parent, resulting in a carrier state, or from both parents for the disease to manifest.

B) Incorrect. While genetic factors are the primary cause of CF, environmental factors can exacerbate symptoms but are not the root cause.

C) Incorrect. CF is not an X-linked genetic disorder; it follows an autosomal recessive pattern of inheritance.

D) Incorrect. CF is not caused by exposure to respiratory pathogens during infancy; it is primarily a genetic disorder.
