Which set correctly lists the three phases of hemostasis?

• A. Primary, Secondary, and Tertiary hemostasis
• B. Primary and Secondary only
• C. Primary and Tertiary only
• D. Secondary and Tertiary only

Answer: (A)

Understanding hemostasis as a sequence helps you see why the complete set is correct. The first phase is a vascular and platelet response: vessels constrict and platelets adhere to the injury to form a platelet plug. The second phase strengthens that plug with a fibrin mesh created by the coagulation cascade, stabilizing the initial plug. The third phase handles cleanup and restoration: fibrinolysis dissolves the clot and tissue repair resumes normal vessel function. So, listing Primary, Secondary, and Tertiary captures the full progression from initial response to clot dissolution and healing. Sets that omit one of these phases don’t describe the entire process, such as missing the dissolution/repair stage or the initial plug formation.
