2. The heart failing to pump, loss of blood volume, dilation of blood vessels.
3. Increased heart rate, increased respiration, constriction of peripheral circulation, pale, cool skin.
4. When perfusion to organs cannot be restored. Cell damage occurs particularly in the kidneys and liver. Death may occur.
5. Hypovolemic (hemorrhaging or blood loss), cardiogenic (heart failure or heart attack), neurogenic (vessel dilation due to nerve damage in spinal cord injuries), sepsis or anaphylactic shock may also cause blood vessel dilation and shock.
6. Treat the cause of the shock. Lay patient down, and raise and support the legs. Be aware of spinal injury or injury to legs before raising them. Keep the patient warm.
7. This solution is isotonic with blood or the same concentration as blood.
8. Restores fluid loss, induces urine output, and helps maintain a normal blood pH.
9. Yes, a first degree burn can become a second degree burn (a sunburn that blisters) and second degree burns may evolve into third degree burns.
10. 50%.

13. Electrical burn, chemical burns.
14. Clean with lukewarm water, remove rings or bracelets, apply a topical antibiotic and update tetanus immunization with a booster if needed.
15. Stridor is caused by upper airway obstruction or narrowing.
16. A mechanical ventilator is a machine that assists with breathing. A patient is connected through an endotracheal tube that is placed in the trachea (windpipe). The mechanical ventilator delivers well oxygenated air into lungs and removes carbon dioxide from the lungs.
17. In adequate respirations from a poorly placed tube, brain damage, cardiac arrest, death. Aspriation of stomach contents can result in pneumonia and acute respiratory distress syndorm. A pneumothorax (collapsed lung) may also occur.
18. To protect her airway.
19. To keep the patient from becoming hypoxic (low in oxygen) or from vomiting and aspirating the vomit into the lungs.
20. X-rays use electromagnetic waves.
21. Ribs and spine.
22. Black (for example, the lungs).
23. 118-210 percent.
24. 25% of preadmission weight.
25. Feedings should start within 4-36 hours after the injury. A high-protein, high-carbohydrate, low-fat diet is recommended.
26. Medical removal of dead, damaged, or infected tissue.
27. Surgical, mechanical, chemical, autolytic, or maggot therapy.
28. Transplantation of skin.
29.
A. Split thickness that includes the epidermis and part of the dermis.
B. Full thickness: consists of epidermis and entire thickness of the dermis.
C. Composite graft: Contains skin and underlying cartilage or other tissue.
30. Packed cells are whole blood minus the plasma or liquid portion of the blood so that only the cells are left. Giving whole blood would be too much fluid for most patients so just the oxygen carrying part of the blood (red blood cells) are transfused.
