1. Which of the following is the most appropriate method to prevent
infection when handling anesthesia equipment?
A. Using cold water to rinse equipment
B. Storing equipment uncovered
C. Following proper sterilization and disinfection protocols
D. Wiping equipment with dry cloths only
Rationale: Proper sterilization and disinfection are essential to
prevent cross-contamination and maintain patient safety.
2. The primary function of a ventilator in the operating room is to:
A. Monitor blood pressure
, B. Provide mechanical ventilation to support or replace spontaneous
breathing
C. Administer intravenous fluids
D. Measure oxygen saturation
Rationale: The ventilator ensures the patient receives adequate
oxygenation and ventilation during anesthesia.
3. Which gas is most commonly used as a carrier gas in general
anesthesia?
A. Nitrous oxide
B. Oxygen
C. Helium
D. Carbon dioxide
Rationale: Oxygen is essential as a carrier gas and for patient safety,
supporting life and transporting anesthetic gases.
4. What is the normal pressure range for an oxygen cylinder in the
operating room?
A. 500–1000 psi
B. 1000–1500 psi
C. 1900–2200 psi
D. 3000–3500 psi
Rationale: A full oxygen cylinder typically reads between 1900–2200
psi; pressures below this indicate depletion.
,5. Which of the following is a common complication of improper
positioning during surgery?
A. Hypoglycemia
B. Hypotension
C. Nerve injury
D. Infection
Rationale: Prolonged pressure on nerves or extremities during
surgery can result in neuropathy or nerve injury.
6. The primary role of the anesthesia technician in preoperative
preparation includes:
A. Performing surgery
B. Ensuring anesthesia equipment is functioning and prepared
C. Administering medications independently
D. Managing post-operative pain
Rationale: The anesthesia technician ensures all equipment, drugs,
and monitoring devices are ready for safe anesthesia delivery.
7. Which of the following agents is considered a volatile anesthetic?
A. Propofol
B. Sevoflurane
C. Midazolam
D. Fentanyl
Rationale: Volatile anesthetics like sevoflurane are inhaled agents
used to maintain general anesthesia.
, 8. What is the purpose of the scavenging system in the OR?
A. Deliver oxygen to the patient
B. Measure blood pressure
C. Remove waste anesthetic gases from the operating room
D. Monitor heart rate
Rationale: Scavenging systems reduce exposure to anesthetic gases
for OR personnel and improve safety.
9. Which of the following is a sign of oxygen cylinder depletion?
A. Increase in cylinder pressure
B. Continuous green color
C. Decrease in cylinder pressure below 500 psi
D. Cylinder temperature rise
Rationale: Low cylinder pressure indicates oxygen is running low and
needs replacement.
10. During anesthesia, a patient develops sudden hypotension. The
anesthesia technician should first:
A. Call the surgeon immediately
B. Check equipment, IV lines, and monitors for issues
C. Stop the anesthesia abruptly
D. Administer antibiotics
Rationale: Equipment or IV problems may cause hypotension; quick
troubleshooting is essential.
