Ch.2 Trauma Shock

Question 1

What is shock?

Answer 1

Inadequate perfusion of the brain and other body cells with oxygenated blood

Question 2

Type of shock caused by loss of fluid volume from bleeding, sweating, vomiting, diarrhea and/or severe burns.

Answer 2

Hypovolemic.

Question 3

Type of shock caused When the heart fails to adequately pump blood.

Answer 3

Cariogenic shock

Question 4

Type of shock caused loss of vascular tone resulting in increased vascular space (spinal cord injury, sepsis and anaphylaxis) SCTM: may still be pink and warm

Answer 4

Vasogenic shock

Question 5

What are the three staged of shock?

Answer 5

1. Compensatory: increased heart rate, respiratory rate to keep blood pressure normal limits to maintain perfusion.
2. Decompensatory: The bodies efforts begin to fail, blood pressure drops, inadequate perfusion begins and brain stops getting oxygenated blood.
3. Irreversible: organs begin to die from inadequate perfusion.

Question 6

Sign and Symptoms of Compensatory Shock?

LOR:
HR:
RR:
SCTM:
Orthostatic(standing on feet) vital signs indication shock(2)
Symptoms:

Answer 6

LOR: anxious, restless and disoriented
HR: rapid
RR: rapid and shallow
SCTM: Pale cool and clammy(maybe pink and warm with vasogenic shock)

Orthostatic(standing on feet) vital signs indication shock(2)

• Patient becomes dizzy or has signs and symptoms of shock in any position.
• Patient stands from flat position after one minuite heart rate increases by 30 beats per minute and/or signs and symptoms of shock develop.

Symptoms: nausea, vomiting, dizziness and thurst.

Question 7

Sign and Symptoms of decompensatry to irreversible Shock?

LOR:
HR:
RR:
SCTM:
Orthostatic(standing on feet) vital signs indication shock(2)
Symptoms:

Answer 7

LOR: deterioration of mental status to unresponsive
HR: Rapid weak eventually slows.
RR:Continues to increase becomes shallower that eventually slows
SCTM: pale cool and clammy and eventually cyanostic or ashen
BP: falls radial pulse weakens eventually disappears.
Pupils: Slower to respond eventually fixed and dilated

Question 8

Treatment Principles of shock(7)

Answer 8

1. Treat the cause
2. Keep patient calm
3. Maintain normal temp. Hypothermia aggravates shock
4. Keep patient flat with legs elevated no more than 12”. head or lower extremity injury may prevent this.
5. Consider oral fluid in an extended care situation, if mental status is adequate.
6. Administer oxygen if available.
7. Monitor patient closely for deteriorating vital signs.
