anaphylactic shock
caused by acute allergic reaction
antigen
anything recognized as foreign by the immune system and produces an immune reaction
cardiogenic shock
caused when the heart is diseased such that it cannot maintain circulation to the tissues
hypovolemic shock
caused by loss of fluids such as occurs during hemorrhaging, extensive burns or severe vomiting or diarrhea

drug/chemical that changes the force of contraction of the heart

type of shock caused by severe infection in the bloodstream
shock
clinical syndrome characterized by collapse of circulatory system
Most types of shock have a high mortality rate.

TRUE or FALSE
TRUE
The side effects of dopamine may be quite serious due to the extremely long half-life of the drug.

TRUE or FALSE
FALSE
