EXAM OVERVIEW
This Final Exam covers comprehensive content from all 23 modules of the AORN Periop 101 curriculum,
including advanced perioperative concepts, sterilization, hemostasis, positioning, anesthesia, and
postoperative care.
QUESTION 1
What is the Spaulding Classification System used for in the perioperative setting?
A) Classifying surgical wounds by contamination level
B) Categorizing medical devices based on infection risk
C) Determining anesthesia risk levels for patients
D) Classifying surgical procedures by complexity
Correct Answer: B
Rationale: The Spaulding Classification System categorizes medical devices and instruments based on the risk
of infection transmission. Critical items (enter sterile tissue) require sterilization, semi-critical items (contact
mucous membranes) require high-level disinfection, and non-critical items (contact intact skin) require low-
level disinfection or cleaning. This system guides processing decisions.
QUESTION 2
Which of the following is the correct sterilization parameter for steam sterilization using gravity
displacement?
A) 250°F (121°C) for 15 minutes at 15-17 psi
B) 270°F (132°C) for 4 minutes at 27-28 psi
C) 250°F (121°C) for 30 minutes at 10 psi
D) 270°F (132°C) for 10 minutes at 20 psi
,2
Correct Answer: A
Rationale: Standard gravity displacement steam sterilization requires exposure to 250°F (121°C) for at least 15
minutes at 15-17 psi. Prevacuum sterilizers operate at 270°F (132°C) for 4 minutes. The time and temperature
parameters are critical for ensuring sterilization effectiveness. Biological indicators should be used to verify
sterilization.
QUESTION 3
What is the biological indicator organism used to monitor steam sterilization?
A) Bacillus atrophaeus
B) Geobacillus stearothermophilus
C) Staphylococcus aureus
D) Escherichia coli
Correct Answer: B
Rationale: Geobacillus stearothermophilus (formerly Bacillus stearothermophilus) is the biological indicator
organism used to monitor steam sterilization. It is the most resistant microorganism to steam and is used as a
standard for verifying sterilization efficacy. Biological indicators provide the highest level of assurance that
sterilization has been achieved.
QUESTION 4
What biological indicator organism is used for ethylene oxide (EO) sterilization?
A) Geobacillus stearothermophilus
B) Bacillus atrophaeus
C) Staphylococcus epidermidis
D) Pseudomonas aeruginosa
Correct Answer: B
Rationale: Bacillus atrophaeus (formerly Bacillus subtilis var. niger) is the biological indicator organism used
for ethylene oxide (EO) sterilization and other low-temperature sterilization processes. EO sterilization
requires lower temperatures (approximately 80-140°F) and longer exposure times. Biological indicators
should be tested with each load.

QUESTION 5
What is the maximum recommended time for a surgical tourniquet to remain inflated?
A) 1 hour
B) 2 hours
C) 3 hours
D) 4 hours
Correct Answer: B
Rationale: The maximum recommended time for a surgical tourniquet to remain inflated is generally 2 hours.
Prolonged inflation increases the risk of nerve damage, tissue ischemia, and reperfusion injury. If the
procedure requires longer than 2 hours, the tourniquet should be deflated for at least 10 minutes before
reinflation. Monitoring tourniquet time is essential for patient safety.
QUESTION 6
Which of the following is the preferred method for preventing unplanned perioperative hypothermia?
A) Increasing room temperature to 75°F
B) Using forced-air warming devices
C) Administering warm IV fluids only
D) Using warm blankets only
Correct Answer: B
Rationale: Forced-air warming devices are the most effective method for preventing unplanned perioperative
hypothermia. These devices deliver warm air through a blanket placed over or under the patient, providing
consistent and controlled warming. Multiple warming modalities may be combined for patients at high risk.
QUESTION 7
Which of the following is the correct pressure range for a pneumatic tourniquet on the upper extremity?
A) 100-150 mmHg
B) 150-200 mmHg
C) 200-250 mmHg
D) 250-300 mmHg
, 4
Correct Answer: C
Rationale: The recommended pressure range for a pneumatic tourniquet on the upper extremity is 200-250
mmHg. For the lower extremity, the range is 250-350 mmHg. The pressure should be based on the patient's
systolic blood pressure and limb circumference. The lowest effective pressure should be used to minimize the
risk of nerve injury.
QUESTION 8
What is the maximum recommended inflation time for a pneumatic tourniquet on the upper extremity?
A) 1 hour
B) 2 hours
C) 3 hours
D) 4 hours
Correct Answer: A
Rationale: The maximum recommended inflation time for a pneumatic tourniquet on the upper extremity is
1 hour. The lower extremity can tolerate up to 2 hours. Tissue ischemia risk increases with inflation time. The
tourniquet should be deflated and allowed to recover for at least 10 minutes before reinflation.
QUESTION 9
Which of the following actions should be taken immediately if malignant hyperthermia is suspected?
A) Administer dantrolene sodium
B) Administer epinephrine
C) Administer sodium bicarbonate
D) Administer mannitol
Correct Answer: A
Rationale: Dantrolene sodium is the primary and specific treatment for malignant hyperthermia. It should be
administered as soon as MH is suspected, along with stopping triggering agents (inhalational anesthetics,
succinylcholine). The initial dose is 2.5 mg/kg IV, repeated until symptoms resolve. Dantrolene works by
reducing calcium release from the sarcoplasmic reticulum.
