Prompt
A Primary data viva — read the cascade by pathway; assign APTT and PT/INR; locate the anticoagulant drug actions.
Stimulus
A Y-shaped coagulation cascade diagram shows the intrinsic (APTT) and extrinsic (PT/INR) pathways converging on the common pathway, with drug-monitoring annotations. Outline each pathway, state which test monitors it, and locate where heparin, warfarin and DOACs act.
