Q

Open head versus close head injury and how are they treated?

A

And open head injury is when the bones of the cranium are fractured. A closed head injury is if the scalp is lacerated but the cranium is intact.

You treat them by:
1. taking appropriate standard precautions.
2. Consider the possibility of a spine injury.
3. Open and maintain airway.
4. Monitor the unconscious patient for changes in breathing.
5. If indicated, apply a rigid cervical collar and initiate spinal motion restriction. 6.Control bleeding.
7. Keep the patient at rest.
8. Talk to the patient and provide emotional support, dress and bandage open wounds
9. manage the patient for shock.
10. Be prepared for vomiting.
11. Transport patient promptly monitor vital signs every 5 minutes.

how to treat heat exhaustion and cramps

A

    2.Loosen or move clothing and cool the patient by fanning without chilling patient. Watch for shivering.
    3.Put the patient in the supine position.
    If the patient is responsive and not nauseated and you will not transport, give the patient small sips of water to drink. If this causes nausea or vomiting, do not give anymore water.

rule of nine
