About this Exam
Prepare with the Arista AH and Surgical Hemostats Practice Test practice quiz. This question bank includes 10 questions covering base, material, hemostasis, describes, and hemostat. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.
Sample Questions
Question
1
Which statement best describes rust's impact on a hemostat during sterile use?
Explanation:
Rust on a hemostat signals metal corrosion, which is harmful in sterile use. It weakens the instrument by forming pits and rough areas, reducing grip strength and precision when you need to clamp or hold tissue. Rust can also shed particles and create crevices that harbor bacteria, contaminating the sterile field and raising infection risk. Those rough, degraded surfaces can irritate or injure tissue as you work, compromising safety. So rust is detrimental to sterility, instrument performance, and patient safety; it does not prevent corrosion, strengthen the surface, or prove harmless.
Question
2
What does ORC stand for?
Explanation:
ORC stands for Oxidized Regenerated Cellulose, a topical hemostatic material made from cellulose that has been chemically oxidized. This oxidation introduces carboxyl groups, giving the fabric an acidic, gel-forming surface when it contacts blood. The material acts as a physical scaffold that concentrates platelets and supports coagulation, helping to stop bleeding. It’s absorbable and typically resorbs over days to weeks, so it can be left in place if needed during healing. The other terms don’t describe the same product: they either imply a different, non-oxidized form or use generic wording that doesn’t capture the specific oxidized cellulose origin and function.
Question
3
Which product uses collagen as its base material?
Explanation:
Collagen-based hemostats use collagen as the underlying material to promote platelet activation and clot formation. Avitene Flowable is a microfibrillar collagen hemostatic agent delivered as a flowable paste, so its base material is collagen. The other products rely on different base materials: Floseal and Surgiflo are gelatin matrices (often with thrombin) that provide a physical scaffold to aid coagulation, while Surgicel Powder is oxidized cellulose that also promotes clotting but is not collagen. So Avitene Flowable is the product that uses collagen as its base material.
Question
4
What best describes the mechanism by which Arista AH promotes hemostasis?
Explanation:
Arista AH works by providing a dry starch-based powder that forms a physical matrix on the bleeding surface. This matrix concentrates platelets and coagulation factors at the site, speeding up the body's natural clotting process to form a stable hemostatic plug. It operates through a mechanical, scaffold-like effect rather than chemical interactions. It isn’t based on chemical cross-linking, oxidation-induced gel formation, or swelling to block the vessel.
Question
5
What is the base material of Surgiflo?
Explanation:
The base material is porcine gelatin. Surgiflo is a gelatin-thrombin matrix used to aid hemostasis, and the gelatin component provides a gel-like carrier that stays at the site of bleeding to localize clot formation. This gelatin is specifically derived from porcine tissue, which is why the correct base is porcine gelatin rather than bovine gelatin or a generic gelatin. Gelatin is a processed form of collagen, so while related, the product uses the gelatin matrix derived from porcine collagen rather than raw collagen fibers.
