Comprehensive Perioperative Nursing and
AORN Standards Practice Exam – Updated
2026 (Graded A+)
Subject: Perioperative Nursing (AORN Standards)
Subtopic: Sterile Technique and Environmental Control
Question 1: During a complex orthopaedic procedure, a scrubbed team member notices a small
tear in their sterile gown located on the left forearm. According to AORN guidelines regarding
the sterile field, which of the following is the most appropriate immediate action?
A) Cover the tear with a sterile adhesive drape and continue the procedure.
B) Have the circulator perform a sterile gown change immediately.
C) Treat the area as non-sterile and ensure no contact is made with the operative site; replace the
gown at the earliest convenience.
D) Use a sterile towel to wrap the forearm and continue the surgery, documenting the incident
post-operatively.
Correct Answer: B - Have the circulator perform a sterile gown change immediately.
Rationale: AORN standards dictate that when a sterile barrier is compromised, the breach must
be addressed immediately to maintain patient safety. The gown is a sterile barrier; a tear
renders it ineffective. Covering it (A) or wrapping it (D) does not restore the integrity of the
barrier. Continuing (C) poses an unnecessary risk of surgical site infection. Immediate
replacement is the only evidence-based action.
Question 2: Which of the following best describes the principle of "restricted" vs. "semi-
restricted" areas within the surgical suite per AORN guidelines?
A) Restricted areas require surgical attire and masks; semi-restricted areas require surgical attire
but masks are optional.
B) Restricted areas are for surgical staff only; semi-restricted areas are open to all hospital
personnel without specific attire requirements.
C) Semi-restricted areas include the sterile storage rooms and corridors; restricted areas include
the operating rooms and scrub sinks.
,D) Restricted areas require head coverings and scrubs; semi-restricted areas do not require any
specific dress code.
Correct Answer: A - Restricted areas require surgical attire and masks; semi-restricted
areas require surgical attire but masks are optional.
Rationale: AORN standards delineate traffic patterns and attire to minimize microbial
contamination. Restricted areas (ORs, sub-sterile rooms) demand full surgical attire (scrubs,
head cover, mask). Semi-restricted areas (corridors, equipment storage) require surgical attire
but do not mandate masks unless the person is in the immediate vicinity of a sterile procedure or
supply.
Question 3: When organizing the sterile field, a perioperative nurse places sterile supplies on a
back table. At what height and level does the AORN consider the sterile field to be established?
A) The entire surface of the table and everything below it.
B) Only the top surface of the table; sides are considered non-sterile.
C) The level of the table surface and the area extending 2 inches below the table edge.
D) The top surface and the area up to 12 inches above the table.
Correct Answer: B - Only the top surface of the table; sides are considered non-sterile.
Rationale: AORN guidelines emphasize that only the surface of a sterile drape that is at table
level is considered sterile. The sides of the table (drape edges extending downward) are
considered non-sterile because they cannot be visually monitored for contamination and are at
risk of brushing against non-sterile surfaces.
Question 4: Regarding the "closed" gloving technique, what is the critical safety rationale behind
this method versus "open" gloving?
A) Closed gloving is faster and allows the surgeon to change gloves more frequently.
B) Closed gloving prevents the skin of the hands from touching the outside of the glove,
reducing the risk of contamination.
C) Closed gloving is only required for high-risk infectious cases.
D) Closed gloving is designed to reduce the risk of glove perforation during suturing.
Correct Answer: B - Closed gloving prevents the skin of the hands from touching the
outside of the glove, reducing the risk of contamination.
,Rationale: The closed gloving technique is the preferred method for the initial gowning and
gloving because the hands remain inside the gown sleeves throughout the process, ensuring that
the sterile exterior of the glove never touches the non-sterile skin of the hands. Open gloving is
used for subsequent changes when the gown cuffs may be contaminated.
Question 5: A patient is scheduled for a surgical procedure. During the "time-out" process, the
nurse notes that the consent form lists the "right knee" but the surgical marking and the OR
schedule indicate the "left knee." What is the mandated action?
A) Proceed with the surgery after confirming verbally with the surgeon that the mark is correct.
B) Pause the procedure, clarify the discrepancy with the surgeon and the patient/family, and do
not proceed until the confusion is resolved.
C) Proceed with the procedure as scheduled and correct the documentation after the surgery
concludes.
D) Ask the anesthesia provider to confirm which side they were prepped for and proceed
accordingly.
Correct Answer: B - Pause the procedure, clarify the discrepancy with the surgeon and the
patient/family, and do not proceed until the confusion is resolved.
Rationale: The "time-out" is a critical safety intervention designed to prevent wrong-site, wrong-
patient, and wrong-procedure errors. Any discrepancy, regardless of how minor it may seem,
must stop the process. Proceeding without clarification (A, C, D) violates the AORN and Joint
Commission standards for patient safety.
Subtopic: Surgical Positioning and Patient Safety
Question 6: Which of the following is the most serious risk associated with the Trendelenburg
position during a long abdominal procedure?
A) Pressure injuries on the heels.
B) Respiratory compromise due to the weight of abdominal contents against the diaphragm.
C) Nerve injury to the brachial plexus.
D) Hypothermia due to the head-down tilt.
Correct Answer: B - Respiratory compromise due to the weight of abdominal contents
against the diaphragm.
Rationale: The Trendelenburg position (head-down) causes the abdominal viscera to shift
cephalad, putting significant pressure on the diaphragm, which can severely limit lung
, expansion and decrease compliance. While nerve injuries and pressure points are risks,
respiratory compromise is the most immediate physiological threat in this position.
Question 7: When positioning a patient in the lithotomy position, why is it vital to ensure that the
legs are raised and lowered simultaneously?
A) To increase the surgeon's access to the perineal area.
B) To prevent torsion of the lumbar spine and pelvic instability.
C) To facilitate easier intubation for the anesthesia provider.
D) To prevent the patient from sliding off the table.
Correct Answer: B - To prevent torsion of the lumbar spine and pelvic instability.
Rationale: Raising or lowering legs independently in the lithotomy position can create unequal
pressure on the hips and rotation in the spine, potentially causing musculoskeletal injury.
Simultaneous movement ensures the hips are supported and the spine remains in a neutral
alignment.
Question 8: A perioperative nurse is preparing a patient for a prone procedure. Which area is at
the highest risk for pressure injury and requires specific padding/positioning support?
A) The popliteal fossa.
B) The forehead and chest.
C) The medial malleolus.
D) The scapular region.
Correct Answer: B - The forehead and chest.
Rationale: In the prone position, the patient's weight is shifted forward. The forehead, eyes, and
chest are highly susceptible to pressure damage, particularly the eyes, where even minimal
pressure can lead to vision loss. Chest rolls are mandatory to allow for diaphragmatic excursion
and to relieve pressure.
Question 9: When applying a grounding pad for a monopolar electrosurgical unit (ESU), what is
the most important site selection criterion according to AORN?
A) As close to the surgical site as possible.
B) Over a large, well-vascularized muscle mass.
