QUESTION 1.
During the pre-anesthesia machine checkout, the low-pressure leak test
demonstrates a gradual decline in bulb inflation after the flow control valves are
closed. Which interpretation most appropriately guides the technician's next action?
,A. A leak exists downstream of the vaporizer and the machine should be removed
from service pending evaluation.
B. The oxygen analyzer requires recalibration before machine use.
C. The scavenging system should be disconnected immediately because it is the
primary cause.
D. The breathing circuit has excessive compliance but is otherwise acceptable.
🔴 Correct Answer: A. A leak exists downstream of the vaporizer and the
machine should be removed from service pending evaluation.
🔵 Explanation: A failed low-pressure leak test indicates a leak within the low-
pressure circuit, which may compromise delivery of anesthetic gases and oxygen. Such
defects can result in hypoxic gas mixtures or inadequate anesthetic delivery. The other
options do not directly explain a failed low-pressure leak test or represent the safest
response.
QUESTION 2.
A patient undergoing prolonged abdominal surgery develops an unexpected
increase in inspired carbon dioxide despite adequate fresh gas flow. Which
equipment malfunction should be considered first?
A. Defective oxygen flush valve
B. Exhausted carbon dioxide absorbent or channeling within the absorber
C. Malfunctioning pulse oximeter probe
D. Improper ECG lead placement
🔴 Correct Answer: B. Exhausted carbon dioxide absorbent or channeling within
the absorber
🔵 Explanation: Elevated inspired carbon dioxide commonly reflects ineffective
carbon dioxide absorption due to exhausted absorbent or gas channeling. This allows
exhaled carbon dioxide to be rebreathed. The remaining options do not directly cause
increased inspired carbon dioxide concentrations.
,QUESTION 3.
During rapid sequence induction, the anesthesia provider requests immediate
preparation for difficult airway rescue after two failed intubation attempts with
declining oxygen saturation. Which action by the anesthesia technician best
supports current airway management priorities?
A. Prepare only a replacement laryngoscope blade.
B. Disconnect capnography to simplify equipment.
C. Prepare advanced airway rescue devices while ensuring suction and oxygen
delivery remain immediately available.
D. Begin cleaning unused airway equipment.
🔴 Correct Answer: C. Prepare advanced airway rescue devices while ensuring
suction and oxygen delivery remain immediately available.
🔵 Explanation: Difficult airway management requires rapid preparation of rescue
devices such as supraglottic airways, video laryngoscopy, or surgical airway
equipment while maintaining oxygenation. Preserving suction and oxygen availability
is essential. The other options fail to support comprehensive airway rescue.
QUESTION 4.
Which monitoring trend most strongly suggests the early development of
malignant hyperthermia during general anesthesia?
A. Gradual reduction in respiratory rate alone
B. Progressive decrease in systolic blood pressure without metabolic changes
C. Stable end-tidal carbon dioxide with isolated mild tachycardia
D. Rapidly increasing end-tidal carbon dioxide accompanied by tachycardia despite
adequate ventilation
🔴 Correct Answer: D. Rapidly increasing end-tidal carbon dioxide accompanied
by tachycardia despite adequate ventilation
🔵 Explanation: A sudden unexplained rise in end-tidal carbon dioxide together with
tachycardia is among the earliest indicators of malignant hyperthermia. Immediate
, recognition allows prompt treatment before severe complications develop. The other
findings are less characteristic of early malignant hyperthermia.
QUESTION 5.
While assisting with a peripheral nerve block, the anesthesia technician observes
that the sterile ultrasound probe cover has been accidentally contaminated before
needle insertion. What is the most appropriate response?
A. Replace the contaminated sterile cover before continuing.
B. Proceed because the contamination occurred before skin puncture.
C. Wipe the contaminated area with alcohol and continue.
D. Ignore the contamination if the provider has already scrubbed.
🔴 Correct Answer: A. Replace the contaminated sterile cover before continuing.
🔵 Explanation: Maintaining sterility throughout regional anesthesia procedures
minimizes infection risk. Any breach in sterile technique requires replacement of
contaminated sterile barriers before proceeding. Cleaning alone does not reliably
restore sterility.
QUESTION 6.
Following replacement of an anesthesia vaporizer, the technician notices an
unexpectedly high delivered anesthetic concentration compared with the dial
setting. Which explanation is most plausible?
A. Excessive fresh gas flow alone always decreases vapor output.
B. Incorrect vaporizer installation or incompatibility resulting in abnormal gas
delivery.
C. Pulse oximeter malfunction.
D. Excess scavenging suction.
🔴 Correct Answer: B. Incorrect vaporizer installation or incompatibility resulting
in abnormal gas delivery.
