First aid help?

First aiders plz help i need to know the following for my upcoming exam thnx soooo much!
鈥?The P's for the Priorities of first aid
鈥he S's when making a diagnosis
鈥reatment of haemorrhage (both an open wound and an internal injury)
鈥reatment for Shock, Poisons and Snakebite
鈥ow the circulatory system works
鈥ow to keep your casualty's airway clear and why this is important
鈥he rates for CPR with one rescuer or with two rescuers when working on an adult or a child
鈥reatment for burns
鈥reating an unconscious casualty especially:
Neck injuries
Head injuries
Seizures
Fainting
HYPOthermia
HYPERthermia
Diabetes

OK, this is a long one.
I don't know what the P's and S's are, but at First Aid level, you don't need to make a diagnosis.
-Bleeding control...direct pressure, elevate, pressure point. For internal bleeding, you can't tell, so if the mechanism of injury suggests blunt trauma, treat for shock.
-Shock...elevate legs, high flow O2.
-Poisons...Call poison control and 911.
-Snakebite...place constrictive band above and below bite. Mark where swelling begins and ends with a marker. Keep bite below level of heart.
-Circulatory system in a nutshell...Heart pumps blood through Aorta, then arteries, then arterioles, then into the capillaries in the tissues and organs, then through the veinuals, the veins, then back to the heart. The heart then pumps the unoxygenated blood to the lungs through the pulmonary arteries. This is where the blood exchanges CO2 for O2. Back to the heart through the pulmonary veins, then back to the body through the Aorta.
-Airway...Head tilt-chin lift on medical patients, jaw thrust on trauma patients. This keeps the tongue from blocking the airway.
-CPR...30-2
-Burns...Superficial - don't touch them, they hurt. Partial thickness - sterile dressings. Full thickness - sterile dressings. If Partial thickness and burns are 10%BSA, use dry dressings. If less than 10% BSA, use moist dressings.
-Unconscious...Don't forget the A,B,C's. If trauma, open the airway with jaw thrust, make sure he's breathing and has a palpable pulse, control major bleeding, then immobilize on a long spine board with cervical collar. If unconscious due to medical condition, A,B,C's, high flow O2.
-Hypothermia...if conscious, warm slowly. If unconscious and CPR is indicated, use long term CPR. No defibrillation.
-Hyperthermia...If conscious and oriented, cool slowly and rehydrate. If altered or unconscious, cool rapidly.
-Diabetes...A,B,C's, Give oral glucose after base hospital physician order. High flow O2.
-Don't forget, monitor vital signs at least every 5 min. on unstable patients and at least every 15 min. on stable patients.
