QUESTION 1
Which laryngeal cartilage is a complete ring located immediately
inferior to the thyroid cartilage and marks the boundary between the
upper and lower airway?
• A. Epiglottis
• B. Cricoid cartilage
• C. Arytenoid cartilage
• D. Corniculate cartilage
Correct Answer: B. Cricoid cartilage
Detailed Rationale: The cricoid cartilage is the only complete
cartilaginous ring in the trachea-laryngeal complex, serving as a critical
landmark for airway management and cricoid pressure.
QUESTION 2
What is the standard formula used to calculate cardiac output?
• A. Heart Rate divided by Stroke Volume
• B. Heart Rate multiplied by Stroke Volume
• C. Blood Pressure multiplied by Systemic Vascular Resistance
• D. Ejection Fraction divided by End-Diastolic Volume
,Correct Answer: B. Heart Rate multiplied by Stroke Volume
Detailed Rationale: Cardiac output represents the total volume of
blood pumped by the heart per minute, calculated as the product of
heart rate (beats/min) and stroke volume (mL/beat).
QUESTION 3
Where are ester-type local anesthetics (such as procaine and tetracaine)
primarily metabolized in the human body?
• A. Microsomal enzymes in the liver (CYP450 system)
• B. Plasma via pseudocholinesterase hydrolysis
• C. Renal tubular excretion without breakdown
• D. Alveolar membrane diffusion
Correct Answer: B. Plasma via pseudocholinesterase hydrolysis
Detailed Rationale: Unlike amide local anesthetics that rely on hepatic
enzymes, ester anesthetics are rapidly hydrolyzed by plasma
pseudocholinesterase enzymes in the bloodstream.
QUESTION 4
What safety system prevents the accidental attachment of an incorrect
medical gas cylinder to the wrong yoke on an anesthesia machine?
• A. Diameter-Index Safety System (DISS)
• B. Pin-Index Safety System (PISS)
• C. Second-stage pressure relief valve
• D. Color-coded flowmeter valve system
Correct Answer: B. Pin-Index Safety System (PISS)
,Detailed Rationale: The Pin-Index Safety System utilizes a specific
pattern of pins on the gas machine yoke that aligns only with matching
pinholes on the corresponding gas cylinder valve block.
QUESTION 5
What does Phase I of a normal capnograph waveform represent?
• A. The baseline zero point during early expiration representing
anatomical dead space gas free of carbon dioxide
• B. The rapid upstroke of mixed alveolar gas
• C. The steady alveolar plateau of expired CO2
• D. The sudden drop during inspiration
Correct Answer: A. The baseline zero point during early expiration
representing anatomical dead space gas free of carbon dioxide
Detailed Rationale: Phase I of the capnogram is the baseline period at
the start of exhalation where gas from the anatomical dead space
(containing no metabolic carbon dioxide) is cleared from the circuit.
QUESTION 6
What is the primary physiological goal of placing a patient in the
Trendelenburg position during an episode of vasodepressor syncope?
• A. To elevate blood pressure by increasing venous return from the
lower extremities to the heart and brain
• B. To force the patient into a deep general anesthesia state
• C. To prevent the aspiration of oral saliva
, • D. To stimulate the carotid sinus baroreceptors to slow the heart
rate
Correct Answer: A. To elevate blood pressure by increasing venous
return from the lower extremities to the heart and brain
Detailed Rationale: Syncope is characterized by cerebral hypoperfusion
due to peripheral pooling; flattening the torso and elevating the legs
uses gravity to restore venous return and brain blood flow.
QUESTION 7
What is the specific pharmacological reversal agent used to treat acute
respiratory depression caused by narcotic overdose?
• A. Flumazenil
• B. Naloxone
• C. Neostigmine
• D. Atropine
Correct Answer: B. Naloxone
Detailed Rationale: Naloxone is a competitive opioid receptor
antagonist that rapidly reverses central nervous system and respiratory
depression induced by opioid medications.
QUESTION 8
According to the Mallampati airway classification, what anatomical
structures are visualized in a Class II airway?
• A. The soft palate, fauces, uvula, and entire pillars are completely
visible.
