2026/2027 |INSTANT DOWNLOAD PDF
1. What is the primary role of an anesthesia technician?
A. Diagnose surgical diseases
B. Administer all anesthetic drugs independently
C. Prepare, maintain, and assist with anesthesia equipment and
supplies
D. Perform surgical procedures
Correct answer: C. Prepare, maintain, and assist with
anesthesia equipment and supplies.
Rationale: An anesthesia technician supports the anesthesia
provider by preparing equipment, supplies, medications as
directed, airway devices, monitoring equipment, and
emergency equipment.
2. Which piece of equipment is used to deliver a controlled
concentration of inhalational anesthetic?
A. Suction regulator
B. Vaporizer
C. Pulse oximeter
D. Laryngoscope
Correct answer: B. Vaporizer.
,Rationale: A vaporizer converts liquid volatile anesthetic into a
controlled concentration of anesthetic vapor for delivery to the
patient.
3. Which monitor measures peripheral oxygen saturation?
A. Capnograph
B. ECG
C. Pulse oximeter
D. Noninvasive blood pressure cuff
Correct answer: C. Pulse oximeter.
Rationale: Pulse oximetry provides an estimate of arterial
oxygen saturation and pulse rate.
4. What does ECG monitoring primarily assess?
A. Oxygen concentration
B. Cardiac electrical activity
C. Carbon dioxide elimination
D. Airway pressure
Correct answer: B. Cardiac electrical activity.
Rationale: An ECG records the electrical activity of the heart
and helps identify rhythm abnormalities and ischemic changes.
,5. Which device is commonly used to visualize the vocal cords
during tracheal intubation?
A. Laryngoscope
B. Stethoscope
C. Bronchoscope only
D. Suction catheter
Correct answer: A. Laryngoscope.
Rationale: A laryngoscope provides visualization of the
laryngeal structures during endotracheal intubation.
6. Which airway device is placed through the mouth or nose
to help maintain airway patency?
A. IV catheter
B. Oropharyngeal airway
C. Arterial catheter
D. Epidural catheter
Correct answer: B. Oropharyngeal airway.
Rationale: An oropharyngeal airway helps prevent the tongue
from obstructing the upper airway in appropriately selected
unconscious patients.
7. Which airway device is commonly used for temporary
ventilation during an emergency?
, A. Bag-mask device
B. Yankauer only
C. ECG electrode
D. Tourniquet
Correct answer: A. Bag-mask device.
Rationale: A bag-mask device allows positive-pressure
ventilation when spontaneous ventilation is inadequate or
absent.
8. What is the main purpose of a breathing circuit?
A. Measure blood glucose
B. Deliver gases to and remove gases from the patient
C. Measure body temperature only
D. Administer IV fluids
Correct answer: B. Deliver gases to and remove gases from the
patient.
Rationale: Breathing systems connect the patient to the
anesthesia machine and facilitate delivery of oxygen/anesthetic
gases and removal of exhaled gases.
9. Which gas is essential for supporting combustion and
human respiration?
A. Nitrogen
B. Oxygen
