1. Which preoperative finding most strongly suggests an increased risk of
difficult mask ventilation?
A. Age 25 years
B. BMI of 22 kg/m²
C. Presence of a beard
D. Normal mandibular protrusion
Answer: Presence of a beard
Rationale: Facial hair can interfere with an effective mask seal and is associated
with increased difficulty in mask ventilation.
2. Which anesthetic agent is most commonly used for rapid induction because
of its rapid onset and favorable hemodynamic profile?
,A. Midazolam
B. Propofol
C. Etomidate
D. Dexmedetomidine
Answer: Etomidate
Rationale: Etomidate produces rapid hypnosis with relatively little
cardiovascular depression, making it useful when hemodynamic stability is
important.
3. Which physiologic change is most likely after induction of general
anesthesia with propofol?
A. Increased systemic vascular resistance
B. Increased sympathetic activity
C. Decreased systemic vascular resistance
D. Increased myocardial contractility
Answer: Decreased systemic vascular resistance
Rationale: Propofol commonly causes vasodilation and reduced systemic
vascular resistance, which can result in hypotension.
4. A patient develops bronchospasm immediately after endotracheal
intubation. Which medication is the most appropriate initial pharmacologic
treatment?
A. Epinephrine
B. Albuterol
C. Furosemide
D. Phenylephrine
Answer: Albuterol
Rationale: Inhaled beta-2 agonists such as albuterol are first-line
bronchodilators for acute intraoperative bronchospasm.
, 5. Which nerve is primarily responsible for motor innervation of the
diaphragm?
A. Vagus nerve
B. Intercostal nerve
C. Phrenic nerve
D. Recurrent laryngeal nerve
Answer: Phrenic nerve
Rationale: The phrenic nerve, arising primarily from C3–C5, provides motor
innervation to the diaphragm.
6. Which ECG finding is most characteristic of hyperkalemia?
A. Prolonged QT interval
B. Peaked T waves
C. U waves
D. ST depression only
Answer: Peaked T waves
Rationale: Hyperkalemia classically produces tall, peaked T waves and may
progress to PR prolongation, QRS widening, and severe conduction
abnormalities.
7. Which medication is commonly used to treat intraoperative hypotension
caused primarily by decreased systemic vascular resistance?
A. Phenylephrine
B. Furosemide
C. Nitroglycerin
D. Esmolol
Answer: Phenylephrine
Rationale: Phenylephrine is an alpha-1 agonist that increases vascular tone and
systemic vascular resistance.
, 8. Which volatile anesthetic has the lowest blood-gas solubility among
commonly used modern inhaled anesthetics?
A. Isoflurane
B. Sevoflurane
C. Desflurane
D. Halothane
Answer: Desflurane
Rationale: Desflurane has very low blood-gas solubility, allowing rapid changes
in anesthetic depth and relatively rapid emergence.
9. Which medication is the specific reversal agent for opioid-induced
respiratory depression?
A. Flumazenil
B. Naloxone
C. Sugammadex
D. Neostigmine
Answer: Naloxone
Rationale: Naloxone is a competitive opioid receptor antagonist that reverses
opioid-induced respiratory and central nervous system depression.
10.Which medication is used to reverse benzodiazepine-induced sedation?
A. Naloxone
B. Atropine
C. Flumazenil
D. Physostigmine
Answer: Flumazenil
Rationale: Flumazenil is a benzodiazepine receptor antagonist that can reverse
benzodiazepine sedation.
11.Which neuromuscular blocking agent is classified as a depolarizing blocker?
