|
Heart, blood vessels, and blood.
|
|
|
What are capillary sphincters?
|
Circular muscles that surround a capillary. Used by autonomic nervous system to direct blood flow to or away from tissue and organs.
|
|
|
What is anaphylactic shock?
|
Severe shock caused by an allergic reaction.
|
|
|
What is anaphylaxis?
|
A severe allergic reaction to a foreign protein or other substance.
|
|
|
What is an aneurysm?
|
A swelling or enlargement of a section of artery due to a weakening of the arterial wall.
|
|
|
What is cardiogenic shock/
|
Shock caused by inadequate heart function. Pump failure.
|
|
|
What is compensated shock?
|
The early stage of shock in which the body can still compensate for the breakdown in the cardio vascular system.
|
|
|
What is cyanosis?
|
Bluish color of the lips and skin due to poor oxygenation of the circulating blood.
|
|
|
What is decompensated shock?
|
The second stage of shock in which the body can no longer maintain homeostasis. BP drops.
|
|
|
What is edema?
|
The presence of unusually high amounts of fluid between the cells in body tissue, causing swelling of the affected area.
|
|
|
What is hypothermia?
|
A condition in which the body temperature drops below 95, usually the result of exposure to cold.
|
|
|
What is hypovolemic shock?
|
Shock caused by fluid or blood loss. Dehydration or bleeding.
|
|
|
What is irreversible shock?
|
The final stage of shock resulting in death.
|
|
|
What is neurogenic shock?
|
Circulatory failure caused by paralysis of the nerves that control dilation of blood vessels. Associated with spinal injuries.
|
|
|
What is psychogenic shock?
|
Shock caused by sudden, temporary reduction in blood supply to the brain resulting in fainting (syncope).
|
|
|
What is hypothermia?
|
A condition in which the body temperature drops below 95, usually the result of exposure to cold.
|
|
|

|
|
|
What is septic shock?
|
Shock caused by severe infection, usually bacterial.
|
|
|
Which subsystem of the nervous system engages when a patient goes into shock and is responsible for the primary signs of shock?
|
The sympathetic nervous system.
|
|
|
What is pulmonary edema?
|
The buildup of fluid (blood) in the lungs due to inadequate heart function.
|
|
|
What is a common and significant complication accompanying neurogenic shock?
|
Hypothermia due to the body's lost ability to self regulate body temperature.
|
|
|
True or False - children and infants can maintain their blood pressure until they have lost more than half of their blood volume?
|
True.
|
|
|
You should expect shock if the patient has any one of these six conditions:
|
1. Multiple severe fractures.
2. Abdominal or chest injury. 3. Spinal injury. 4. A severe infection. 5. A major heart attack. 6. Anaphylaxis. |
|
|
Would a neurogenic shock patient display tachycardia or bradycardia?
|
Bradycardia.
|
|
|
What skin condition would you expect for a patient with septic shock?
|
Warm and pale.
|
|
|
What is the first step in the treatment of cardiogenic shock?
|
Place the patient in a position in which breathing is easiest (usually sitting) and administer high flow oxygen.
|
|
|
What is the best form of treatment for neurogenic shock?
|
Employ all known supportive measures and initiate rapid transport.
|
|
|
What is the most important thing you can do for a patient who is in hypovolemic shock due to internal bleeding?
|
Provide rapid transport to the ER.
|
|
|
What should you do if you suspect you patient is suffering from septic shock?
|
Use appropriate BSI precautions and initiate rapid transport to the ER.
