NSG 5140- Shock Questions and
Answers.
shock - Answer A condition in which the circulatory system fails to provide sufficient
circulation to enable every body part to perform its function



hypovolemic shock - Answer shock resulting from blood or fluid loss



septic shock - Answer Septic shock develops due to a widespread infection causing organ
failure and dangerously low blood pressure.



stages of shock - Answer Initial

Compensatory

Progressive

Refractory



stage 1: initial - Answer - usually not apparent

- aerobic -> anaerobic = form lactic acid

- increase HR and mild vasoconstriction



Stage 2: Compensatory - Answer - decrease in blood pressure

- increased lactic acid

- decrease in pH, hyperkalemia

- increased HR, RR, fluid retention

- thirst, decrease pulse pressure



stage 3: progressive - Answer - compensatory mechanisms fail

- increased anaerobic metabolism

- altered capillary permeability- fluid leaks into the tissue causing hypotension

- hypotension, poor O2, tachycardia, cyanosis, hypoxia, acidosis, tissue death



Stage 4: Refractory - Answer - high mortality

- exacerbated anaerobic metabolism

- accumulation of lactic acid

- venous pooling
