Which option correctly matches the 3g Arista AH coverage area?

• A. ~29 cm²
• B. ~126 cm²
• C. ~83 cm²
• D. ~52 cm²

Answer: (C)

Understanding how much surface area a 3 g piece of Arista AH covers helps you estimate how much to apply to a bleeding site. Arista AH is a hemostatic gauze that swells and forms a clot-promoting matrix when in contact with blood. The standard application for a 3 g piece corresponds to roughly 83 cm^2 of surface coverage in a single, even layer. This is why the best match is about 83 cm^2. If the area to treat is larger, you’d apply additional material or overlap pieces; if smaller, you’d use less or fold appropriately. The other area values don’t align with the typical 3 g coverage specification.
