The nurse providing instructions to the client using an incentive spirometer tells the client to sustain the inhaled breath for 3 seconds
When the client asks the nurse about the rationale for this action, the nurse explains that the primary benefit is to: 1. Dilate the major bronchi.
2. Maintain inflation of the alveoli.
3. Increase surfactant production.
4. Enhance ciliary action in the tracheobronchial tree.
2
Rationale: Sustained inhalation helps maintain inflation of terminal bronchioles and alveoli, thereby promoting better gas exchange. Routine use of such devices such an incentive spirometer can help prevent atelectasis and pneumonia in clients at risk. "Dilate the major bronchi," "increase surfactant production," and "enhance ciliary action in the tracheobronchial tree" are not reasons for sustaining inflation.
