When preparing for preoperative skin prep and draping, which sequence best maintains sterility and infection prevention?

	Place drapes first → perform skin prep through fenestration → allow drying under drapes
	Gather sterile prep supplies → perform skin prep starting at incision → allow drying → place sterile towels → apply larger drapes
	Prepare supplies → remove hair the night before with razor → perform antisepsis on day of surgery
	Apply antiseptic → immediately drape over wet skin → secure with clips

During prep for an abdominal surgery, a nurse’s applicator accidentally brushes the patient’s unprepped thigh, then is reused to swab near the incision. What best describes the outcome?

	Sterile field preserved — the applicator was still within the prepped area
	Sterile field preserved — antiseptic solution on the applicator eliminates all bacteria
	Sterile field compromised — microorganisms from the thigh may have been dragged toward the incision
	Sterile field preserved if the site is draped quickly afterwards

Which agent is safest and most effective for intact skin in most surgical sites?

	Povidone-iodine applied briefly, without drying
	Chlorhexidine in alcohol solution
	Aqueous chlorhexidine used once without alcohol
	Sterile saline

During hip arthroplasty, a fenestrated drape is misaligned, leaving part of the incision site uncovered. The nurse repositions the drape toward the incision. What is the outcome?

	Sterile field preserved — antiseptic under the drape prevents contamination
	Sterile field preserved — only the top side of the drape was moved
	Sterile field preserved if an adhesive strip covers the exposed skin
	Sterile field compromised — dragging the drape toward the incision introduces contamination

Why must drapes be dry and intact before use?

	Because damp drapes cannot cover the entire site effectively
	Because wet drapes slide off more easily
	Because holes or moisture allow strike-through, letting microorganisms migrate from underside to sterile top
	Because dampness inactivates antiseptic already applied to the skin

In a rural OR, the only available drapes are sterilized cloth sheets, one of which has a small tear at the corner far from the incision site. What is the best course?

	Discard the drape immediately even if no alternative is available
	Cover the tear with a sterile towel or another drape, ensuring it is excluded from the operative zone
	Proceed without covering the tear since it is far from the incision
	Ignore the tear because antiseptic prep compensates for it

Why must alcohol-based antiseptics dry completely before draping?

	To allow drapes to adhere better to the skin
	To prevent patients from feeling cold during surgery
	To reduce pooling under the drapes
	To activate antimicrobial properties and prevent fire hazards with electrosurgical devices

Which of the following would break the sterile field during skin prep and draping?

	Using multiple sterile applicators to cover skin folds thoroughly
	Reaching across a prepped site with a non-sterile arm while placing a towel
	Applying antiseptic in concentric circles from the incision outward
	Discarding each used applicator into a sterile waste receptacle

A patient with eczema and broken skin near the incision site is prepped for vascular surgery. Which approach is most appropriate?

	Skip antiseptic to avoid irritating the skin
	Apply povidone-iodine full strength directly over broken skin
	Use diluted chlorhexidine or saline, avoiding alcohol-based solutions
	Apply alcohol-based chlorhexidine liberally to maximize kill

Why is reusing antiseptic solution across multiple patients unsafe?

	Because once contaminated, the shared solution can transmit microorganisms between patients
	Because antiseptic loses its chemical potency after one use
	Because antiseptics are single-use by manufacturer instruction only, not clinical risk
	Because antiseptic becomes too dilute after several dips
