During setup, the scrub nurse correctly arranges heavy basins at the back table base. While applying sterile drapes, one drape edge falls below waist level but is lifted back up before touching the table. What is the correct response?

	Discard and replace the drape immediately
	Use the drape since it did not touch the floor
	Continue using the drape if no visible contamination is present
	Cover the fallen edge with another sterile towel

Which of the following is the correct principle when organizing sharps during sterile setup?

	Scalpels and scissors may be placed together in the Mayo stand for immediate access
	Needles can remain in unopened sterile packs until needed to minimize exposure
	Sharps should be spread throughout the back table to minimize crowding
	Scalpels, needles, and other sharps must be isolated in a defined zone for counting and safety

Which is the correct order of instrument categories for a standard procedure (e.g., appendectomy)?

	Cutting → Clamping → Tissue-handling → Suturing
	Tissue-handling → Cutting → Suturing → Clamping
	Suturing → Clamping → Cutting → Tissue-handling
	Clamping → Cutting → Suturing → Tissue-handling

Which instruments should be placed on the Mayo stand for immediate use at the start of surgery?

	Sponges, suction tubing, and towel clips
	Retractors, tissue forceps, and markers
	Basins, clamps, and sterile packs
	Scalpel, scissors, hemostats, and one needle holder with suture

During the initial count, one suture needle is missing from a sterile pack. The circulator suggests documenting it as “not present” and proceeding. What is the correct response?

	Proceed with the remaining needles since all others were counted
	Document the missing item and use the pack to avoid delays
	Remove the entire pack and replace it before surgery begins
	Add a needle from another pack to complete the count

When opening a sterile pack, which technique is correct?

	Tear the packaging quickly to avoid contact
	Place items directly onto the sterile field without a landing zone
	Unfold flaps away from the body, keeping arms clear of the sterile contents
	Unfold the last flap toward the body to stabilize the pack

Which check is most appropriate before surgery begins?

	Skip testing basic instruments as they are “routine.”
	Verify instruments are free of water spots or discoloration after sterilization
	Scissors tested for sharpness, clamps checked for locking, hinges assessed for smooth movement
	Instruments checked only if visibly damaged

While arranging the back table, the scrub nurse brushes a sterile glove against the non-sterile anesthesia cart but notices no visible soil. What should be done?

	Continue using the glove since nothing visible transferred
	Spray the glove with antiseptic before continuing
	Cover the glove with a sterile towel and proceed
	Replace the contaminated glove immediately

In a low-resource OR where only two sterile towels are available, what is the safest adaptation?

	Reuse non-sterile cloths for draping if visibly clean
	Skip towel use entirely if patient is already prepped
	Use expired sterile towels if packaging is intact
	Repurpose sterile towels as drape extensions, ensuring team communication and documentation

During final sterile field preparation, the suction unit fails its check. The scrub nurse has already arranged instruments, counts are complete, and the patient is anesthetized. What is the correct next step?

	Halt and obtain a functioning suction unit before incision begins
	Proceed with incision while the circulator arranges a replacement suction unit
	Begin surgery using sterile sponges for fluid management until suction arrives
	Continue since oxygen and anesthesia are functioning; suction can be deferred
