**Question 1. Which of the following best describes the anatomic location of the glottic
opening?**
A) Between the epiglottis and the arytenoid cartilages
B) Between the vocal cords
C) At the level of the thyroid cartilage
D) Posterior to the cricoid cartilage
Answer: B
Explanation: The glottic opening is the space between the true vocal cords, allowing air passage
during respiration.
**Question 2. In the ASA Physical Status Classification, a patient with well‑controlled
hypertension and type 2 diabetes mellitus would be classified as:**
A) ASA I
B) ASA II
C) ASA III
D) ASA IV
Answer: B
Explanation: ASA II denotes a patient with mild systemic disease that is well controlled, such as
hypertension or diabetes without end‑organ damage.
**Question 3. The “Pin Index Safety System” (PISS) is used to prevent which of the following
errors?**
A) Incorrect connection of the breathing circuit

Certification Review Guide
B) Administration of the wrong volatile anesthetic agent
C) Delivery of the wrong oxygen cylinder
D) Over‑pressurization of the scavenging system
Answer: C
Explanation: PISS uses a unique arrangement of pins on oxygen and nitrous oxide cylinders to
prevent mis‑attachment of the wrong gas.
**Question 4. Which component of the anesthesia machine directly measures the fraction of
inspired oxygen (FiO₂) delivered to the patient?**
A) Flowmeter
B) Vaporizer
C) Oxygen analyzer
D) Pressure gauge
Answer: C
Explanation: The oxygen analyzer provides a real‑time measurement of FiO₂ in the fresh gas
flow.
**Question 5. In a Mapleson D breathing circuit, the fresh gas flow is most efficiently used when
the patient is:**
A) Receiving controlled ventilation
B) Spontaneously breathing
C) Apneic
D) Undergoing high‑frequency ventilation

Certification Review Guide
Answer: B
Explanation: Mapleson D circuits are most efficient for spontaneously breathing patients
because the fresh gas flow is taken in after the patient exhales, minimizing rebreathing.
**Question 6. Which of the following capnography waveforms is most characteristic of a sudden
decrease in cardiac output?**
A) A gradual rise in EtCO₂ followed by a plateau
B) A sharp, high‑frequency oscillation
C) A sudden drop in EtCO₂ amplitude
D) A biphasic waveform with two peaks
Answer: C
Explanation: A rapid fall in EtCO₂ reflects reduced pulmonary perfusion due to decreased
cardiac output.
**Question 7. The primary determinant of the minimum alveolar concentration (MAC) of an
inhalational agent is:**
A) Blood‑gas partition coefficient
B) Lipid solubility
C) Vapor pressure at room temperature
D) Molecular weight
Answer: B

Explanation: MAC is inversely related to lipid solubility; agents with higher lipid solubility have
lower MAC values.
**Question 8. Which inhalational anesthetic has the fastest onset and offset due to its low
blood‑gas solubility?**
A. Isoflurane
B. Sevoflurane
C. Desflurane
D. Halothane
Answer: C
Explanation: Desflurane has the lowest blood‑gas partition coefficient among commonly used
volatile agents, providing rapid induction and emergence.
**Question 9. Succinylcholine is contraindicated in patients with which of the following
conditions?**
A) Chronic obstructive pulmonary disease (COPD)
B) Hyperkalemia
C) Myasthenia gravis
D) Acute renal failure
Answer: B
Explanation: Succinylcholine can cause a massive rise in serum potassium, which is dangerous in
patients already hyperkalemic.
