AORN Periop 101 Advanced Prep: Master
Perioperative Nursing Practice Questions &
Detailed Explanations
Subject: Perioperative Nursing (Periop 101) – Patient Safety, Aseptic Technique,
and Surgical Procedures
Question 1: During the intraoperative phase, a patient exhibits signs of Malignant Hyperthermia
(MH). Beyond the immediate cessation of volatile anesthetic agents and succinylcholine, which
intervention is the priority for the perioperative nurse?
A) Administering a bolus of warmed isotonic saline to increase core temperature.
B) Assisting in the administration of dantrolene sodium while monitoring for cardiac
dysrhythmias.
C) Applying a cooling blanket directly to the patient's skin without an interposing barrier.
D) Increasing the oxygen flow rate to 100% and preparing for immediate elective surgery
termination.
Correct Answer: B) Administering a dantrolene sodium bolus while monitoring for cardiac
dysrhythmias.
Explanation: Dantrolene sodium is the specific pharmacological antidote for MH. It works by
interfering with the release of calcium from the sarcoplasmic reticulum in skeletal muscle cells.
Monitoring is crucial because dantrolene can cause muscle weakness and cardiac distress.
Distractor C is incorrect because a barrier must be used to prevent thermal skin injury, and
Distractor A is contraindicated as the patient is hyperthermic.
Question 2: When performing a surgical hand scrub, the perioperative nurse follows the brush-
stroke method. If the nurse accidentally touches the sink faucet with their elbow during the
process, what is the correct sequence of actions?
A) Proceed to the operating room and inform the scrub technician to re-scrub the affected area.
B) Complete the scrub process, then apply a higher concentration of antimicrobial soap for 30
seconds.
C) Immediately restart the entire surgical hand scrub process from the beginning.
D) Apply sterile alcohol-based hand rub to the entire arm and glove immediately upon entering
the OR.
,Correct Answer: C) Immediately restart the entire surgical hand scrub process from the
beginning.
Explanation: Aseptic technique requires the maintenance of sterility. If any part of the hands or
arms—which are considered "surgically clean" after a scrub—touches a non-sterile object, the
integrity of the process is compromised, necessitating a full restart to ensure patient safety.
Question 3: Which of the following best describes the principle of "Patient Positioning" in the
prevention of intraoperative peripheral nerve injuries?
A) Ensuring the head and neck are hyper-extended to improve airway access for the anesthesia
team.
B) Maintaining the patient's arms at an angle greater than 90 degrees to facilitate surgical access.
C) Padding bony prominences and ensuring joints are in a neutral position to prevent nerve
compression.
D) Securing the patient with tight restraints to prevent accidental movement under general
anesthesia.
Correct Answer: C) Padding bony prominences and ensuring joints are in a neutral position
to prevent nerve compression.
Explanation: Peripheral nerve injuries often occur due to prolonged pressure, stretching, or
direct compression against rigid equipment. Padding and neutral alignment minimize the risk of
brachial plexus or ulnar nerve injury. Distractor B is incorrect as abduction greater than 90
degrees increases the risk of brachial plexus stretch.
Question 4: When managing a "Surgical Site Infection" (SSI) risk, what is the significance of
the "Time Out" procedure as defined by The Joint Commission?
A) It is the time for the surgeon to discuss the specifics of the procedure with the patient’s
family.
B) It serves as a final, mandatory verification of the correct patient, site, and procedure
immediately before incision.
C) It allows the nurse to complete all documentation before the surgery begins.
D) It is an optional break for the surgical team to reduce fatigue and increase focus.
Correct Answer: B) It serves as a final, mandatory verification of the correct patient, site,
and procedure immediately before incision.
, Explanation: The "Time Out" is a critical patient safety intervention designed to prevent "wrong
site, wrong procedure, wrong patient" errors. It must be a consensus-based communication
where all team members stop and verify the essential surgical details.
Question 5: In the sterile field, the "sterile border" is generally defined as how many inches from
the edge of a draped table?
A) 1 inch
B) 3 inches
C) 6 inches
D) 12 inches
Correct Answer: A) 1 inch
Explanation: AORN standards establish that the edge of any sterile drape is considered
contaminated. The 1-inch border is the established margin of safety that must be respected by all
sterile personnel.
Question 6: Which instrument should the scrub person prepare first for a standard surgical set-
up to ensure efficiency?
A) The scalpel handle with blade.
B) The suction tip and tubing.
C) The towel clips for securing drapes.
D) The suture material.
Correct Answer: C) The towel clips for securing drapes.
Explanation: Efficiency in the OR relies on the sequence of events. Draping occurs immediately
after the patient is positioned and prepped; therefore, the tools required for draping (towel clips)
must be available first.
Question 7: A patient is undergoing an emergency procedure and has a known allergy to latex.
Which of the following precautions is mandatory?
A) Using only powder-free, non-latex gloves for the entire surgical team.
B) Using double-gloving with standard latex gloves, as long as the inner glove is non-latex.
C) Washing all instruments twice in a standard detergent.
