A nurse sets up a sterile field on the overbed table and then turns away from the field to retrieve additional supplies from the supply cart behind her. Which sterile technique principle has the nurse violated?

A The 1-inch border rule — the edge of the sterile drape was not maintained B Sterile field integrity — a sterile field must remain within the nurse's direct line of sight at all times C Strike-through contamination — turning away causes moisture transfer to the drape D The sequential gloving rule — gloves must be donned before the field is established

True or False: A sterile field that has been left unattended for two minutes in an empty room with the door closed is still considered sterile and safe to use.

T True F False

A nurse needs an item that has been placed on the far side of a sterile field. To retrieve it, the nurse reaches directly across the center of the sterile drape with a sterile-gloved hand. Which principle has the nurse violated?

A No principle is violated — sterile gloves make this action acceptable B Sterile field integrity — reaching across the field passes a non-sterile body part (the arm and sleeve) over the sterile surface, risking contamination C Strike-through contamination — perspiration from the arm can wick through the glove D The 1-inch border rule — the item on the far side is in the non-sterile border zone

During a bedside sterile dressing change, a nurse inadvertently lowers the overbed table so that the sterile field drops below the level of the nurse's waist. Which sterile technique violation has occurred?

A No violation — table height does not affect sterility B Strike-through contamination — the lowered surface is more likely to become wet C Waist-level contamination — any sterile item or surface positioned below the waist is considered non-sterile D The 1-inch border rule — border integrity is lost when the table is lowered

During a sterile procedure setup, a nurse accidentally knocks over a small basin of normal saline, soaking the sterile drape. The drape is resting on a non-absorbent plastic tray. The nurse proceeds with the procedure, believing the plastic tray prevents contamination. Which violation has occurred?

A No violation — the non-absorbent plastic tray prevents strike-through contamination B Strike-through contamination — a sterile barrier that has become wet is considered contaminated regardless of the underlying surface C The 1-inch border rule — the saline only contaminated the border zone D Sterile field integrity — the drape is contaminated only if the nurse leaves the room

True or False: A sterile drape that has become wet during a procedure is still considered sterile if it is immediately moved to a completely dry surface.

T True F False

A nurse prepares to perform a sterile urinary catheterization at the bedside. After opening the catheter kit, the nurse unfolds the sterile drape and places it directly on the overbed table, which has a small pool of water from a recently emptied water pitcher. Which violation has occurred?

A No violation — the water is clean tap water and does not contain pathogens B The 1-inch border rule — the wet surface only compromises the border zone of the drape C Strike-through contamination — moisture on the non-sterile surface wicks upward through the drape, contaminating the sterile side D Sterile field integrity — the drape is contaminated only if the nurse turns away from it

A nurse is setting up a sterile field for a wound irrigation procedure. After opening the sterile drape, the nurse places a pair of sterile forceps directly at the very edge of the drape, with the tips touching the outer border. Which principle has the nurse violated?

A No principle is violated — the forceps are still on the drape surface B The 1-inch (2.5 cm) border rule — the outer margin of the sterile drape is non-sterile and items placed there are considered contaminated C Strike-through contamination — metal forceps placed at the edge cause moisture transfer D Sterile field integrity — forceps must remain in the center of the field at all times

During setup of a sterile field, a nurse wearing sterile gloves reaches toward the 1 cm outer margin of the drape to reposition a sterile gauze pad that has drifted too close to the edge. Which sterile technique error has occurred?

A No error — the nurse is wearing sterile gloves, so contact with the border is acceptable B The 1-inch border rule — the outer 2.5 cm border is non-sterile; touching it with a sterile glove contaminates the glove C Waist-level contamination — reaching toward the border lowers the hand below the waist D Sterile field integrity — repositioning items on the field after setup is always prohibited

True or False: The outer 2.5 cm (1 inch) border of a sterile drape is considered part of the sterile field and may be used to place sterile instruments.

T True F False

A nurse without sterile gloves is assisting a sterile-gloved colleague during a complex dressing change. The non-sterile nurse opens a sterile package, peels back the outer wrapper, and then hands the inner sterile wrapper — touching the inner surface — directly to the sterile-gloved nurse. Which violation has occurred?

A No violation — the sterile-gloved nurse received the item and it is now protected B The non-sterile nurse contaminated the inner surface by touching it; the sterile-gloved nurse should not accept this item C Strike-through contamination — the inner wrapper became wet during handling D The 1-inch border rule — the non-sterile nurse should have held the outer wrapper only at the border

A nurse needs to add a sterile gauze package to an established sterile field. Standing approximately one foot away, the nurse flips the package from the outer wrapper so it lands on the sterile drape — but it comes to rest with one corner of the gauze packet overlapping the 1-inch border of the drape. Which error has the nurse made?

A No error — the majority of the gauze packet is on the sterile field B The gauze packet is contaminated because any part of a sterile item that contacts or overlaps the non-sterile border renders the entire item non-sterile C Strike-through contamination — tossing items onto the field causes moisture transfer D Sterile field integrity — items must never be tossed or dropped onto a sterile field

During setup for a sterile irrigation procedure, a nurse pours sterile normal saline from a large bottle into a sterile basin. While pouring, the lip of the bottle makes brief contact with the rim of the sterile basin. Which violation has occurred?

A No violation — the saline is sterile, so contact between the bottle and basin is acceptable B The bottle lip is considered non-sterile; contact between it and the sterile basin has contaminated the basin and its contents C Strike-through contamination — the poured saline soaked through the drape below the basin D The 1-inch border rule — the bottle should be held over the border zone when pouring

A nurse is applying sterile gloves using the open-gloving technique. After donning the first (dominant-hand) glove using the bare non-dominant hand, the nurse picks up the second glove by grasping its outer surface with the bare non-dominant hand to pull it on. Which violation has occurred?

A No violation — the bare hand may touch the exterior of the glove as long as it does not touch the interior B The bare hand has contaminated the outer surface of the second glove by direct contact; the glove is no longer sterile C Strike-through contamination — perspiration from the bare hand wicks through the glove material D No violation — the outer surface of a sterile glove is non-sterile by convention

True or False: During the closed-gloving technique, the nurse's bare hands never directly contact the outer (sterile) surface of the sterile gloves.

T True F False

A nurse has just finished donning sterile gloves in preparation for a catheter insertion. Before approaching the patient, the nurse realizes her eyeglasses have slipped down her nose and uses a sterile-gloved finger to push them back up. Which violation has the nurse committed?

A No violation — the nurse touched only her own face, not the sterile field B The sterile gloves are now contaminated because the nurse touched a non-sterile surface (her face and glasses) with the sterile gloves C The 1-inch border rule — the nurse should have touched only the frame of the glasses, not the lenses D Strike-through contamination — facial oils transferred through the glove material

During a female urinary catheterization, a nurse cleans the urethral meatus and inserts the catheter approximately 2 cm before realizing it has been misplaced into the vaginal vault. The nurse withdraws the catheter and attempts to insert it a second time into the correct opening without changing to a new catheter. Which violation has occurred?

A No violation — the catheter was only inserted 2 cm and can be reused for the correct opening B The catheter is contaminated after contact with the vaginal vault; reinserting it introduces vaginal flora into the urethra and bladder, violating sterile technique C Strike-through contamination — the catheter became wet inside the vagina D The 1-inch border rule — the catheter must be repositioned at least 1 inch from the meatus before reinsertion

A nurse sets up a complete sterile catheterization kit at the bedside of a female patient, opens all supplies, and places the sterile drape. The nurse then realizes she forgot the correct catheter size in the supply room. She steps out of the room to retrieve it, leaving the open sterile field unattended, and returns two minutes later to complete the procedure. Which violation has the nurse made?

A No violation — the room was empty and the field was undisturbed B The sterile field is contaminated because it was left unattended; the entire setup must be discarded and reconstructed with new supplies C Strike-through contamination — the unattended field is susceptible to environmental moisture D The 1-inch border rule — leaving the room compromises the border zone of the sterile drape

During a urinary catheterization, a nurse's sterile-gloved hand briefly contacts the patient's inner thigh while spreading the labia for urethral visualization. The nurse continues with the procedure without changing gloves. Which error in sterile technique has occurred?

A No error — the inner thigh is a clean area and does not contaminate the sterile glove B The sterile glove is contaminated because the patient's skin — including the inner thigh — is a non-sterile surface; the nurse must re-glove before proceeding C Strike-through contamination — perspiration from the thigh wicks through the glove D No error — contact with the patient's skin is unavoidable and expected during catheterization

A nurse enters a patient's room to perform a sterile wound dressing change. The nurse dons clean gloves, removes the soiled dressing, and then — without changing gloves — opens the sterile supplies and begins applying the new sterile dressing. Which violation has occurred?

A No violation — clean gloves are acceptable for both removal and application of wound dressings B The nurse used the same contaminated gloves (used to remove the soiled dressing) to handle and apply sterile supplies, violating sterile technique and increasing infection risk C Strike-through contamination — the soiled dressing transferred moisture to the new dressing D The 1-inch border rule — the new sterile dressing was placed too close to the wound edge

During a sterile wound dressing change, a patient turns her head and produces an uncontrolled cough that blows across the open sterile field from approximately 18 inches away. The nurse continues setting up the dressing without reconstructing the field. Which principle has been violated?

A No principle is violated — a single cough at 18 inches does not contaminate a sterile field B Sterile field integrity — respiratory droplets and airborne particles from a cough can deposit organisms on the sterile field, rendering it contaminated C Strike-through contamination — moisture from the cough soaked through the drape D The 1-inch border rule — only the border zone of the field is affected by the cough

During a sterile wound dressing change, a nurse notices excess exudate at the wound margin. To absorb it quickly, the nurse folds the edge of the sterile drape — the outer 1-inch border — and uses it to blot the wound drainage, then proceeds with the dressing change. Which violation has occurred?

A No violation — using the drape border is acceptable because the border is separate from the sterile field B The 1-inch border rule — using the non-sterile border to contact the wound introduces non-sterile material to the wound site, and the maneuver also risks dragging the non-sterile border across the sterile field C Strike-through contamination — wound exudate soaked through the border into the sterile field D Sterile field integrity — touching the wound with the drape contaminated the drape's sterile center

A nurse retrieves a sterile supply package from the unit storage shelf and notices a small but definite tear in the outer plastic wrapper before opening it. The package is within its expiration date and the inner contents appear dry. The nurse decides to use the package because the tear is small. Which principle has been violated?

A No principle is violated — a small tear does not breach the inner sterile barrier B The 'when in doubt, throw it out' principle — compromised packaging cannot guarantee sterility and the item must be discarded C Strike-through contamination — the tear allows moisture to enter and contaminate the contents D The 1-inch border rule — the tear is at the border of the packaging and does not affect the inner contents

During preparation for a urinary catheterization, a nurse retrieves a catheter insertion kit from the supply closet and notes that the printed expiration date on the package reads yesterday's date. The kit's packaging is intact and dry. The nurse decides to proceed with the kit, reasoning that it expired only one day ago and is probably still safe. Which violation has occurred?

A No violation — expiration dates on sterile supplies have a 24-hour grace period B The 'when in doubt, throw it out' principle — an expired sterile kit cannot be guaranteed sterile and must be discarded regardless of apparent packaging integrity C Strike-through contamination — expired kits are more likely to have moisture inside the packaging D Sterile field integrity — expired items may be used if a supervising nurse verifies their condition
