Shock

Question 1

The normal perfusion of the body requires
four intact components:

Answer 1

Blood Vessels
Oxygenation
Red Blood cells & plasma
The Heart

Question 2

Blood Pressure=

Answer 2

Cardiac Output x Peripheral Vascular Resistance

Question 3

Early Shock

Answer 3

Compensated shock
Loss of approximately 15-25% of the blood volume.

Question 4

Late Shock

Answer 4

Decompensated shock
Loss of approximately 30-45% of the blood volume.

Question 5

Low Volume Shock

Answer 5

• Absolute hypovolemia
• Loss of volume

Question 6

Hypovolemic Shock

Answer 6

Causes: Internal/External Hemorrhage & any major body fluid loss

Question 7

High Space Shock

Answer 7

• Relative Hypovolemia
• Vasodilatory Shock
• Interruption of sympathetic nervous system
• Loss of normal vasoconstriction; vascular space becomes too large

Question 8

Septic Shock

Answer 8

• Result of widespread infection
• Complex interactions between pathogen and body’s defense systems
• Uncontrolled and unregulated inflammatory-immune response

Question 9

Neurogenic Shock

Answer 9

• Described as decreased sympathetic control of blood vessel tone due to a
  defect in the vasomotor center in the brain stem.
• No catecholamine release (epinephrine & norepinephrine)
• Most common cause is spinal cord injury

Question 10

Anaphylactic Shock

Answer 10

• Severe systemic allergic reaction
• Results from immune reaction in which vasodilator substances (histamine) are released into the blood

Question 11

Cardiogenic or Obstructive Shock

Answer 11

Any traumatic or medical condition that slows or prevents the venous return of blood can cause shock by lowering cardiac output ie.tamponade,tension pneumo
