Comprehension of Current Situation
synthesis of combined cues: Interpretation of vital signs and clinical presentation
Acute transfusion reaction
Identifying Patterns

Projection of Future Status
What will happen if adverse reaction is left alone
Acute transfusion reaction
Anticipate/Infer consequences of actions
Acute injury, shock, DIC, death
What will happen if blood transfusion is stopped
Decision Making
Performance of action
