05. Hemolytic disease of the newborn could be of concern when an

Rh-positive fetus and an Rh-negative mother condition occur

Stoppage of bleeding, called hemostasis, involves three defense mechanisms: blood vessel spasm, platelet plug formation, and coagulation. The coagulation mechanism involves a series of chain reactions that result in a blood clot. The final stage of the series of reactions occurs when thrombin converts a soluble plasma protein called fibrinogen into insoluble fibrin.
