Answer: Paramedics are the medical professionals which perform multitasking in providing medical aid to the patients in the field as well as in the hospital.

Problems encountered by the paramedic at the accidental scene:
1. Major problem is the collection of the blood and other bodily fluids for examination as it is contaminated over spilling on the road.
2. Stabilizing and uplifting of the patient found on accident and curating them to ambulance is a labor consuming task.
3. Some body parts are severely damaged in accidents some of which includes those parts which covers the vital organs like ribs, spinal cord, skull, and pelvis so stabilizing those parts is a risky task for paramedics and can even kill the patient.
