Know treatment for different kinds of burns (chemical, thermal) – Thermal: o Use sterile dressings o Nerve apply ointments, sprays, or butters Do not break blisters – Chemical o Wash away chemicals with copious amounts of flowing water o If dry chemical, brush away, then flush with water o Remove Contaminated clothing o Apply sterile dressings o Treat for shock 3. Know how to calculate body surface area burned – Rules of Nines o Adult body divided into 11 main areas o Each represent 9% of body surface – Rule of Palms o a hand represents 1% 4. Know treatment for suspected fracture – Splint the body part and check for distal pulses 5.

Know what “battle’s sign” is – Seen with head injuries – Bruising behind the ears 17. Know what “Cushing’s response, or Cushing’s triad” is – Patient has an increased blood pressure and decreased pulse rate from a head injury 18. Know what injuries require an occlusive dressing – Neck, Chest, and Abdomen Sucking Chest wound – Burp the occlusive dressing (release a corner to release air) if a patient begins to be more short of breath 19. Know about heat loss – Convection o Process of heat loss as wind passes over it – Conduction o Transfer of heat for one material to another through direct contact – Passive Rewarming o Cover the patient o Remove wet clothing o Lets the body rewarm itself – Active Rewarming o Application of an external heat source to rewarm the body – Body Shivers to produce heat 20.

Know treatment for drowning – Provide recue breaths If no pulse is found, being CPR – Treat for shock – Patient is not dead until they are warm and dead 21. Know treatment for evisceration – organs are protruding – Treatment: Sterile moistened dressings, keep warm with bulky dressings. 22. Know treatment for shock – Aggressive airway maintenance – Oxygen – Attempt to stop cause of shock – PASG – Splint any suspected bone or injuries – Prevent loss of body heat – “Golden hour” – speak calmly and reassure throughout assessment and care 23.
