What is a key safety consideration to avoid when using Arista AH?

• A. Do not inject into blood vessels or intravascularly.
• B. Avoid contact with saline irrigation.
• C. Do not apply near nerve tissue.
• D. Do not use in patients with a history of smoking.

Answer: (A)

The safety principle being tested is preventing material from entering the vascular system. Arista AH is a topical hemostatic agent that aids clot formation at the bleeding site by providing a scaffold for the coagulation process. If this material is injected or washes into a blood vessel, it can travel as an embolus and block vessels, potentially causing serious ischemia in tissues or organs. So the best practice is to apply Arista AH only to the bleeding surface and avoid intravascular administration; manage the area with careful technique and remove any excess material as directed. Other options don’t reflect the same critical risk: the product is not inherently avoided with saline contact in typical use, isn’t specifically contraindicated near nerves, and smoking history is not a contraindication.
