Which form factor category does Arista AH fall into?

• A. Fabric
• B. Flowable
• C. Patch Hemostat
• D. Powder

Answer: (D)

This question tests form factor in surgical hemostatic agents and how the product is delivered to the bleeding site. Arista AH is a powder form factor—a sterile, dry, free-flowing powder that you apply directly to the bleeding surface, often with a dedicated applicator. The powder works by rapidly absorbing water from the blood, which concentrates platelets and clotting factors to accelerate clot formation. This makes it ideal for diffuse oozing and irregular surfaces where a patch or sponge would be harder to place. It isn’t a fabric-based sponge, nor a patch that covers a wound, and it isn’t a flowable gel or paste, which would behave differently on tissue.
