Final answer:
When spinal injuries are suspected, the EMS provider should prioritize the following actions in order to ensure the safety and well-being of the patient: 4) Apply manual stabilization and secure the airway.
Step-by-step explanation:
The primary concern in cases of suspected spinal injuries is to prevent any further harm to the spinal cord. Therefore, manual stabilization of the head and neck is crucial to minimize movement and potential damage. Once manual stabilization is in place, securing the airway is important for maintaining proper breathing and oxygenation.
Options such as jaw thrust maneuvers can be used to open the airway without hyperextending the neck. After initial stabilization and securing the airway, further assessments and interventions can be carried out as needed, such as determining the extent of paralysis and applying extrication collars for additional support. The answer is option 4.
