Scenаriо: Yоu аnd yоur pаrtner, both AEMTs, are dispatched to a residential home for a 62-year-old male patient who has fallen from a ladder. Upon arrival, you find the patient lying supine in the backyard on uneven terrain. The patient is conscious but complains of severe back pain and mild difficulty breathing. He also has a history of hypertension and chronic back issues. The scene is complicated by the location—there are narrow stairs leading to the house, and the backyard has uneven ground. You perform a primary assessment and determine that the patient does not have any life-threatening injuries, but you need to immobilize him to prevent further damage to his spine. Post Scene: What should you do FIRST to prepare the stretcher for the next call?
