If a client after a fire has dyspnea and neck trauma, what intervention is most appropriate?

The most appropriate intervention in this scenario is the jaw-thrust maneuver. When a client presents with dyspnea and potential neck trauma, preserving the spinal alignment is critical to avoid exacerbating any injuries that may have occurred in the cervical spine. The jaw-thrust maneuver is particularly advantageous in these cases as it allows for the airway to be opened without tilting the head or neck, minimizing the risk of any further injury to an already compromised area.

In contrast, the head tilt-chin lift maneuver involves tilting the head back, which can potentially worsen neck injury if a spinal injury is present. Chest compressions would not address the immediate issue of airway obstruction or breathing difficulties related to the dyspnea. While administering supplemental oxygen provides essential support for respiratory distress, it does not directly address the need to establish and maintain a patent airway in a client who may also have neck injuries. Therefore, the jaw-thrust maneuver is the safest and most effective choice in this scenario to ensure airway management while considering the client's trauma.
