Cha 2 Exam 5: Shock Exam Study Guide.
Adequate Perfusion Requires: - answer✔✔- Working pump (heart)
- Working vascular system
- Adequate blood supply
Body's Response to Stress - answer✔✔- Inflammatory response + coagulation pathway
- CNS stimulation
- SNS stimulation
- RAAS stimulation
- Release of pituitary hormones
Shock - answer✔✔A complex syndrome characterized by decreased tissue perfusion and
impaired cellular metabolism
Shock (what happens) - answer✔✔Imbalance of oxygen and nutrient supply to cells leads to
hypoxia and accumulation of metabolic wastes - cells die
Oxygenation and Perfusion - answer✔✔Depend on: effective gas exchange, total blood volume,
CO, size/integrity of capillary bed
Shock (some causes) - answer✔✔Infection, CVD, Neuro injury, burns, trauma, anephylaxis,
surgery, inflammation, hemorrhage
Risk for Shock - answer✔✔Age (young/old), malnourished, smoking, alcohol/drug abuse,
altered fluid volume status, some medications, chronic illness (DM II, COPD, GI ulcers, cancer,
etc.), surgery, invasive procedures, altered skin integrity, allergy, immunosuppressants, risk for
trauma or hemorrhage
4 phases of Shock - answer✔✔1: Initial
2: Non-progressive (compensatory)
3: Progressive
4: Refractory
