EMS Unit 108
Respond to Centennial Park on HighlandAvenue—you have a female patient at that
location who suffered a burn.
Time out 1306
Upon Arrival
• You position the ambulance out of the flow of traffic• A bystander runs up and says, “A woman wastrying to refuel her son’s model airplane and it blewup!”• The patient is sitting on a patch of grass about 15feet away from a smoldering model plane
How would you proceed to assess andcare for this patient?

You position the ambulance out of the flowof traffic. A woman runs up to you andsays, “A woman over here was trying torefuel her son’s model airplane when thegas tank blew up or something.” Yourpatient is sitting on a patch of grass about15 feet away from a smoldering modelplane.
CASE STUDYCASE STUDYUpon Arrival
• 23-year-old male with multiple stab woundsto the neck, right front chest, and abdomen
• He is screaming in painVital signs:• BP: 88/68 mmHg• Radial pulse is weak and rapid• RR: 28 per minute• Skin is pale, cool, and clammy
Critical Thinking Scenario
1. What body systems do you suspect couldbe injured by the knife wounds?
2. Using medical terminology and anatomicalterms, give hypothetical examples of howto describe the wounds to the neck, chestand abdomen in a written EMS report.
3. What is causing the elevated heart rate?
