In the RAPID protocol, which step follows removing excess blood?

• A. Irrigate and remove excess Arista AH.
• B. Apply Arista AH liberally.
• C. Done: hemostasis achieved.
• D. Pressure until hemostasis.

Answer: (B)

In topical hemostasis with Arista AH, the surface must be clear so the product can contact the bleeding tissue and start clot formation. After removing excess blood, the next step is to apply Arista AH liberally to the bleeding surface. This ensures the hemostatic material is in direct contact with tissue to accelerate clotting. Irrigating again or trying to press before applying the agent would either wash away or fail to establish the necessary contact. After the agent is in place, you then apply pressure to tamponade the site and drive hemostasis, then confirm stability of the bleed.
