What is the safest hemostatic adjustment?\n|type=\"()\"}\n+ Substitute mechanical or chemical methods for electrosurgery\n|| '''Correct: Using non-electrical hemostatic methods (e.g., pressure, clips, or chemical agents) prevents electromagnetic interference with pacemaker function.'''\n- Proceed with diathermy using minimal settings\n|| Incorrect: Even minimal electrosurgical current can disrupt pacemaker rhythm or damage leads.\n- Request fibrin sealant as a prophylactic measure\n|| Incorrect: Fibrin sealant assists clotting but does not eliminate electrical risk.\n- Delay surgery until cardiology clearance is obtained\n|| Incorrect: Surgery can proceed safely using alternative hemostasis methods.\n\n{Which of the following topical hemostatic agents should not be used in an infected or contaminated surgical field?\n|type=\"()\"}\n- Gelatin sponge\n|| Incorrect: Gelatin sponges can be used cautiously unless abscess formation is a concern.\n- Fibrin sealant\n|| Incorrect: Fibrin sealant is not inherently contraindicated in infection but should be used judiciously.\n- Microfibrillar collagen\n|| Incorrect: Collagen is acceptable in most cases if no hypersensitivity exists.\n+ Oxidized cellulose\n|| '''Correct: Oxidized cellulose promotes bacterial proliferation and should be avoided in contaminated or infected surgical sites.'''\n\n{The circulating nurse is preparing for a liver resection with anticipated blood loss. Which preparatory step best ensures rapid response to hemorrhage?\n|type=\"()\"}\n+ Confirming blood products are crossmatched and transport-ready\n|| '''Correct: Having crossmatched, transport-ready blood available allows immediate transfusion response during significant intraoperative hemorrhage.'''\n- Checking stapler cartridge loads before incision\n|| Incorrect: While important, this does not address systemic readiness for blood loss.\n- Laying out the smallest sponges closest to the surgeon\n|| Incorrect: Sponge organization aids field control but not hemorrhage management.\n- Ensuring irrigation fluids are cooled to minimize enzyme degradation\n|| Incorrect: Cold irrigation increases hypothermia and coagulopathy risk.\n\n{During active arterial bleeding, the scrub nurse hands the surgeon a vascular clamp with the ratchets locked and oriented away from the surgeon’s hand. What is the most appropriate correction?\n|type=\"()\"}\n- Use a smaller clamp regardless of vessel size for precision\n|| Incorrect: Clamp size must correspond to vessel diameter to avoid tissue damage or inadequate occlusion.\n- Keep the ratchets locked to prevent accidental release once applied\n|| Incorrect: Locked ratchets slow application and limit quick repositioning during bleeding.\n+ Unlock the ratchets and reorient the clamp tips toward the surgeon before passing\n|| '''Correct: Clamps should be passed unlocked and oriented correctly for immediate, precise placement and rapid bleeding control.'''\n- Replace the clamp with a tourniquet for faster control\n|| Incorrect: Tourniquets are for limb control, not localized arterial bleeding.\n\n</quiz>\n\n{{Return to main}}\n\n{{Page data\n| part-of = Hemostasis Management - ECSACONM#Electro-surgical Methods of Bleeding Control\n| sdg = SDG03 Good health and well-being\n| organizations = ECSACONM, SELF\n| keywords = surgery, health\n}}"}
