A client sustained a crush injury to the chest and is diagnosed with a flail chest. On assessment the nurse should expect to observe

A. Reposition the client in high-Fowler's position and reassess breath sounds: While positioning can improve ventilation, the absence of previously heard wheezes suggests worsening airway obstruction. Simple repositioning is unlikely to relieve a rapidly progressing airway compromise caused by inhalation injury.

B. Encourage the client to cough and auscultate the lungs again: Coughing may help clear secretions in some situations, but in the context of inhalation injury with decreasing breath sounds, the client is at high risk for complete airway obstruction. Encouraging cough does not address the imminent threat to airway patency.

C. Notify the health care provider and prepare for endotracheal intubation: Diminished or absent breath sounds after initial wheezing indicate progressive airway edema and potential obstruction. Early recognition and preparation for intubation are critical to secure the airway before it becomes impossible to manage. Immediate action is essential to prevent respiratory failure.

D. Document the results and continue to monitor the client's respiratory rate: Simply documenting and monitoring delays urgent intervention and places the client at high risk for complete airway obstruction. This passive approach does not address the acute airway emergency and could result in life-threatening hypoxia.

A. Prevents overinflation of the cuff which can lead to tracheoesophageal fistula: Maintaining cuff pressure between 15 to 25 cm H₂O prevents excessive pressure on the tracheal mucosa, which can cause ischemia, necrosis, and complications such as tracheoesophageal fistula. Proper cuff inflation balances the need to seal the airway while minimizing tissue injury, ensuring safe long-term tracheostomy care.

B. Allows the client to speak without aspirating: While cuff deflation or use of a speaking valve enables phonation, cuff pressure maintenance is primarily for airway protection rather than facilitating speech. Speaking is a secondary concern and is managed separately from strict cuff pressure monitoring.

C. Allows for passage of oxygen around the cuff: The cuff is designed to create a seal and prevent air leaks; maintaining appropriate pressure does not intentionally allow oxygen to pass around it. Allowing oxygen to leak around the cuff would compromise ventilation and increase aspiration risk.

D. Allows for more effective suctioning: Suctioning is performed either through an open or closed system and is independent of cuff pressure. The cuff’s main role is to protect the lower airway and prevent aspiration, not to enhance suctioning effectiveness.
