1. Which factor most directly increases the speed of induction of inhaled
anesthetic?
A. Increased functional residual capacity
B. Increased alveolar ventilation
C. Increased blood-gas solubility
D. Increased cardiac output
Answer: B. Increased alveolar ventilation
Rationale: Increased alveolar ventilation delivers anesthetic to the alveoli more
rapidly, accelerating the rise in alveolar and brain partial pressure.
2. Which inhaled anesthetic has the lowest blood-gas partition coefficient?
A. Isoflurane
B. Sevoflurane
C. Desflurane
D. Halothane
Answer: C. Desflurane
,Rationale: Desflurane has very low blood solubility, allowing rapid changes in
alveolar concentration and relatively rapid emergence.
3. A patient develops severe hypotension immediately after induction. Which
cause should be considered first?
A. Increased systemic vascular resistance
B. Reduced sympathetic tone and myocardial depression
C. Increased circulating blood volume
D. Increased venous return
Answer: B. Reduced sympathetic tone and myocardial depression
Rationale: Induction agents can reduce sympathetic tone and myocardial
contractility, producing vasodilation and hypotension.
4. Which medication is commonly used to reverse opioid-induced respiratory
depression?
A. Flumazenil
B. Naloxone
C. Sugammadex
D. Neostigmine
Answer: B. Naloxone
Rationale: Naloxone is an opioid receptor antagonist used to reverse clinically
significant opioid-induced respiratory depression.
5. Which medication selectively reverses the effects of rocuronium and
vecuronium?
A. Atropine
B. Neostigmine
C. Sugammadex
D. Glycopyrrolate
Answer: C. Sugammadex
,Rationale: Sugammadex encapsulates aminosteroid neuromuscular blockers
such as rocuronium and vecuronium, rapidly reducing their free plasma
concentration.
6. Which monitoring modality provides the most direct information about
ventilation during general anesthesia?
A. Pulse oximetry
B. Electrocardiography
C. Capnography
D. Temperature monitoring
Answer: C. Capnography
Rationale: Capnography continuously measures exhaled carbon dioxide and
provides direct information about ventilation and airway integrity.
7. A sudden loss of the capnography waveform during anesthesia should initially
prompt evaluation for:
A. Hyperglycemia
B. Circuit disconnection or apnea
C. Hypertension
D. Hypothermia
Answer: B. Circuit disconnection or apnea
Rationale: Abrupt disappearance of the end-tidal carbon dioxide waveform can
indicate apnea, disconnection, accidental extubation, or another major
interruption of ventilation.
8. Which physiologic change commonly occurs during pregnancy?
A. Decreased oxygen consumption
B. Decreased minute ventilation
C. Increased functional residual capacity
D. Increased oxygen consumption
Answer: D. Increased oxygen consumption
, Rationale: Pregnancy increases maternal oxygen consumption while reducing
functional residual capacity, decreasing the oxygen reserve during apnea.
9. Which condition is associated with a prolonged QT interval?
A. Hypokalemia
B. Hypernatremia
C. Hyperchloremia
D. Hypermagnesemia
Answer: A. Hypokalemia
Rationale: Hypokalemia can prolong ventricular repolarization and increase the
risk of ventricular arrhythmias, particularly torsades de pointes.
10. What is the primary determinant of cerebral perfusion pressure?
A. Mean arterial pressure minus intracranial pressure
B. Systolic pressure plus intracranial pressure
C. Heart rate minus mean arterial pressure
D. Central venous pressure plus systolic pressure
Answer: A. Mean arterial pressure minus intracranial pressure
Rationale: Cerebral perfusion pressure is calculated as mean arterial pressure
minus intracranial pressure.
11. Which drug is a direct-acting sympathomimetic commonly used to treat
perioperative hypotension?
A. Phenylephrine
B. Midazolam
C. Ondansetron
D. Furosemide
Answer: A. Phenylephrine
Rationale: Phenylephrine primarily stimulates alpha-1 receptors, increasing
vascular tone and systemic vascular resistance.
