A hiker has fallen while trying to scale a rocky cliff. Gabe is one of the paramedics who arrives at the scene. The road is very close to the edge of the cliff, and peering down, Gabe can see the hiker in a thicket below. Once he and his partner get to the hiker, Gabe can see that they are unconscious. He must get them transported back up to the road and into the ambulance. What piece of equipment would Gabe MOST likely use to get this patient back up the rocky cliff?
a
a draw sheet to slide the patient up
b
a slide board to carry the patient up
c
a sling lift brought from the hospital
d
a stretcher from the ambulance
