Which maneuver is recommended to open the airway of a client suspected to have a cervical spine injury?

A. Finger sweep: This is used only if a foreign object is visible in the mouth or airway. It does not open the airway and can be harmful if blindly performed. B. Heimlich maneuver: This is used to relieve airway obstruction due to choking, not to open the airway in an unconscious client. C. Head tilt/chin lift: This is a common method to open the airway, but contraindicated in suspected cervical spine injury, as it may cause spinal movement. D. Jaw thrust: The jaw thrust maneuver is recommended because it opens the airway without moving the cervical spine, reducing the risk of spinal cord injury.
