How long should you wait to assess hemostasis after applying Arista AH?

• A. Typically 1–3 minutes.
• B. Typically 10–15 minutes.
• C. Immediately within seconds.
• D. Never assess; assume successful.

Answer: (A)

After applying Arista AH, give it a brief moment for it to interact with the blood and begin forming a clot. The typical waiting period is about 1 to 3 minutes. During this time, observe the site for cessation of bleeding and a stable clot. If bleeding persists, you can apply more material and then re-check. Waiting longer than necessary delays the procedure, and checking immediately may not give the agent time to work. Always verify hemostasis before concluding.
