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.

"If both parents are carriers, their child will be a carrier but will not have CF." D. "If both parents are carriers, their child will have a 25% chance of having CF."

Correct Answer is D

Explanation

A) Incorrect. If both parents are carriers, their child's risk of having CF is 25%, not 50%.

B) Incorrect. While the risk is increased, having two carrier parents does not guarantee that a child will have CF.

D) Correct. When both parents are carriers, there is a 25% chance that their child will inherit two CF genes and have CF, a 50% chance of being a carrier, and a 25% chance of inheriting two normal genes (no CF).
