,Q1 APPLY AORN STANDARDS TO PERIOPERATIVE PATIENT CARE ACROSS THE SURGICAL
CONTINUUM
In a hybrid operating room, a patient undergoing a complex endovascular aortic
repair requires intraoperative imaging. The team plans to use a mobile C-arm with
a flat-panel detector. Which radiation safety practice most effectively minimizes
occupational dose while maintaining image quality?
A. Use the lowest possible pulse rate and frame rate that still provides adequate visualization
CORRECT
B. Maximize the source-to-image distance to reduce scatter radiation
C. Position the image intensifier as close to the patient as possible to magnify the image
D. Use lead aprons and thyroid shields exclusively, as dosimeters are not required for low-dose
cases
RATIONALE: Lowering pulse and frame rates directly reduces radiation exposure time and dose,
while maintaining diagnostic image quality for fluoroscopic guidance. Increasing source-to-image
distance actually increases patient dose and scatter, and close positioning of the image
intensifier improves image quality but does not primarily reduce occupational dose. Lead aprons
are necessary but do not eliminate the need for dose optimization and monitoring.
Q2 APPLY AORN STANDARDS TO PERIOPERATIVE PATIENT CARE ACROSS THE SURGICAL
CONTINUUM
During a laparoscopic cholecystectomy, the surgeon requests a 30° scope. The
circulating nurse notices the camera image is upside down. What is the most likely
cause and the appropriate corrective action?
A. The light cable is not fully inserted; reinsert it until it clicks
B. The camera head is not oriented correctly; rotate it 180° to align with the scope CORRECT
C. The scope's fiberoptic bundles are damaged; replace the scope
D. The white balance was not performed; recalibrate the camera
RATIONALE: A 30° scope has a beveled tip that allows angulation; when the camera head is not
aligned with the scope's orientation, the image can appear rotated or upside down. Rotating the
camera head 180° corrects the orientation. Light cable issues cause darkness, not orientation
problems; damaged fibers cause image degradation; white balance affects color, not orientation.

CONTINUUM
A surgical technologist is preparing the sterile field for a total knee arthroplasty.
Which action demonstrates correct aseptic technique when opening a sterile
basin?
A. Open the wrapper's first flap away from the body, then open the side flaps with ungloved
hands
B. After opening, reach over the basin to adjust the sterile drape
C. Hold the basin with one hand and peel the wrapper back with the other, keeping the inner
surface sterile CORRECT
D. Open the basin on a non-sterile surface, then use sterile forceps to transfer it to the field
RATIONALE: When opening a sterile basin, the wrapper should be peeled back carefully so that
the inner surface remains sterile and does not touch non-sterile surfaces. Opening the first flap
away from the body and side flaps without reaching over is correct for wrapped items, but for a
basin, the method described in C is standard. Reaching over the sterile field contaminates it, and
opening on a non-sterile surface then transferring with forceps is not as safe as direct opening.
Q4 APPLY AORN STANDARDS TO PERIOPERATIVE PATIENT CARE ACROSS THE SURGICAL
CONTINUUM
During a robotic prostatectomy, the patient is placed in steep Trendelenburg
position. The anesthesia provider notes a sudden decrease in end-tidal CO2 and
oxygen saturation. What is the most likely cause and immediate nursing action?
A. Carbon dioxide embolism; notify the surgeon and lower the patient's head to a less steep
angle
B. Endotracheal tube migration into the right mainstem bronchus; auscultate breath sounds and
notify anesthesia CORRECT
C. Venous air embolism; place the patient in left lateral decubitus position
D. Pneumothorax from barotrauma; prepare for needle decompression
RATIONALE: Steep Trendelenburg can cause cephalad displacement of the endotracheal tube,
leading to mainstem intubation, which presents with decreased ETCO2 and SpO2. The nurse
should assist with assessment and repositioning of the tube. CO2 embolism is rare in this context
and would cause a rapid drop in ETCO2 but is less likely than tube migration. Venous air
embolism is not typical in this setting. Pneumothorax would have different findings and is less
likely.

, Q5 APPLY AORN STANDARDS TO PERIOPERATIVE PATIENT CARE ACROSS THE SURGICAL
CONTINUUM
A patient is scheduled for an open abdominal surgery. The surgeon requests that
the electrosurgical unit (ESU) be set to 'spray' mode. Which tissue effect is
expected, and what safety consideration is paramount?
A. Deep coagulation with minimal charring; ensure the patient return electrode is placed on a
well-perfused muscle
B. Superficial coagulation with a non-contact spray; avoid using in the presence of flammable
prep solutions CORRECT
C. Cutting with minimal hemostasis; use a lower power setting to prevent thermal injury
D. Fulguration with a contact technique; ensure the active electrode is fully insulated
RATIONALE: Spray mode delivers high-voltage, low-current energy to a tissue from a distance,
causing superficial coagulation and desiccation. Because it produces sparks, it poses a fire
hazard if alcohol-based prep solutions are present. Deep coagulation is typical of 'desiccate'
mode, and cutting is achieved in 'cut' mode. Contact fulguration is not the same as spray.
Q6 APPLY AORN STANDARDS TO PERIOPERATIVE PATIENT CARE ACROSS THE SURGICAL
CONTINUUM
When positioning a patient for a posterior fossa craniotomy in the sitting position,
which physiological change is of greatest concern to the perioperative nurse?
A. Increased venous return leading to cardiac overload
B. Orthostatic hypotension and risk of venous air embolism CORRECT
C. Increased intracranial pressure due to head elevation
D. Compression of the brachial plexus from arm positioning
RATIONALE: The sitting position increases the risk of venous air embolism because the surgical
site is above the level of the heart, allowing air to be entrained into open veins. It also can cause
orthostatic hypotension. Venous return is actually decreased, not increased. Intracranial pressure
is reduced with head elevation. Brachial plexus injury is a risk but not the most physiological
concern.
