Hemostatic agents are defined as

• B. Imaging dyes used in radiology
• C. Substances applied such as powders, dressings, gauze or bandages
• D. Antibiotic drops for infection

Answer: (C)

Hemostatic agents are substances applied to a bleeding wound to promote rapid clot formation and help stop the bleed. They come in forms you can place on the wound—powders, dressings, gauze, or bandages—that contain materials designed to enhance coagulation or create a local clotting environment. They’re used when direct pressure alone doesn’t control severe bleeding or when a wound is hard to compress, such as in traumatic injuries or junctional areas. They are not pain medications, imaging dyes, or antibiotics, which serve different purposes. The main idea is that the material actively aids the body's clotting response at the site.
