Applicators come first, towels for outlining are next, and drapes are only applied once antiseptic is dry.'''\n- Sterile drapes should be laid out first, with antiseptic applicators last\n|| \"Drapes are not applied until prep is complete and antiseptic dried; placing them first risks breaking sequence and contamination.\"\n- Waste bag and timing device must be positioned sterilely alongside applicators\n|| \"Waste bag and timer are important but remain non-sterile items; they are not part of the sterile field sequence.\"\n- Sterile gloves are not required for skin prep as long as clean technique is used\n|| \"Sterile gloves are essential for handling sterile applicators and supplies; clean technique is insufficient.\"\n\n{A patient scheduled for inguinal hernia repair has a history of eczema with broken patches of skin near the operative site. Which antiseptic approach is most appropriate?\n|type=\"()\"}\n- Apply full-strength povidone-iodine directly over the broken skin to maximize antimicrobial effect\n|| \"Full-strength iodine can worsen irritation and tissue damage in broken skin.\"\n+ Use diluted chlorhexidine or saline on broken skin, ensuring thorough coverage but avoiding alcohol-based solutions\n|| '''Broken or inflamed skin cannot tolerate alcohol-based solutions; diluted chlorhexidine or saline reduces microbial load while minimizing irritation.'''\n- Alcohol-based chlorhexidine should be applied liberally to achieve the strongest microbial kill\n|| \"Alcohol is contraindicated on broken skin because it causes tissue damage and pain.\"\n- Skin prep should be skipped on the affected area to avoid further irritation\n|| \"Skipping prep leaves microbial load high, increasing SSI risk.\"\n\n{Why must sterile drapes be inspected for moisture before use, particularly in low-resource settings where cloth drapes may be common?\n|type=\"()\"}\n- Because a moist drape loses its ability to cover the entire operative site\n|| \"Size coverage is unrelated to moisture; the issue is microbial migration.\"\n- Because damp cloth reduces the adhesive property of towel clips\n|| \"Clips anchor drapes mechanically; their function is not dependent on moisture.\"\n+ Because moisture allows microorganisms to wick through fabric, compromising the sterile barrier\n|| '''Damp drapes enable “strike-through” contamination, where bacteria travel from the non-sterile underside to the sterile top.'''\n- Because a moist drape indicates the patient may not have been prepped adequately\n|| \"Moisture in drapes comes from storage or sterilization, not patient prep.\"\n\n{During a C-section in a low-resource hospital, the team realizes that the only fenestrated drape available has a small tear at the edge. What is the best course of action?\n|type=\"()\"}\n+ Overlay the damaged area with an intact sterile towel or drape, ensuring the tear is sealed away from the operative site\n|| '''If the defect can be isolated and sealed, sterility is maintained without discarding the whole drape — essential in low-resource settings.'''\n- Proceed with the drape as is, since the tear is small and unlikely to matter\n|| ''Even small breaches are contamination pathways; ignoring them compromises sterility.''\n- Discard the drape and delay the case until another fenestrated drape is sterilized\n|| ''This may be impossible in low-resource contexts; it causes unsafe delay when safer adaptations exist.''\n- Cover the tear with adhesive tape from the non-sterile field\n|| ''Non-sterile tape introduces contamination into the sterile field.''\n\n</quiz>\n\n{{Return to main}}\n\n{{Page data\n| part-of = Skin Preparation - ECSACONM\n| sdg = SDG03 Good health and well-being\n| organizations = ECSACONM, SELF\n| keywords = surgery, health\n}}"}
