Which of the following best describes the coverage area of the 5g Arista AH?

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

Answer: (A)

The main idea here is how much surface a single 5 g dose of Arista AH can effectively cover when applied as a thin, even layer. The standard dosing guidance indicates that a 5 g amount is enough to cover roughly 126 cm^2 of bleeding surface. Thinking of it visually, that’s about a square 11 cm on each side (a round area would be similar in size, since the area of a circle with radius ~6.3 cm is close to 126 cm^2). This helps clinicians estimate how much surface can be treated with one dose and plan dosing accordingly.

If you imagine applying too thick a layer, you’d cover less area with the same weight, which is why the 126 cm^2 figure represents a light, even distribution. The other numbers would imply either a thicker application or a smaller treated area, which isn’t how a standard 5 g dose is intended to be used.
