1. Which structure is primarily responsible for preventing aspiration during
swallowing?
A. Vocal cords
B. Epiglottis
C. Uvula
D. Soft palate
Answer: B. Epiglottis
Rationale: The epiglottis helps direct food and liquid away from the laryngeal
inlet during swallowing, reducing the risk of aspiration.
2. Which cardiac chamber pumps oxygenated blood into the systemic
circulation?
A. Right atrium
B. Right ventricle
C. Left atrium
D. Left ventricle
Answer: D. Left ventricle
,Rationale: The left ventricle generates the pressure necessary to eject
oxygenated blood through the aorta into systemic circulation.
3. Which anesthetic agent is most associated with dose-dependent myocardial
depression?
A. Sevoflurane
B. Nitrous oxide
C. Ketamine
D. Dexmedetomidine
Answer: A. Sevoflurane
Rationale: Volatile anesthetics such as sevoflurane can produce dose-dependent
myocardial depression and reductions in arterial blood pressure.
4. What is the primary purpose of preoxygenation before induction of general
anesthesia?
A. Increase carbon dioxide production
B. Replace alveolar nitrogen with oxygen
C. Increase metabolic oxygen consumption
D. Prevent postoperative nausea
Answer: B. Replace alveolar nitrogen with oxygen
Rationale: Preoxygenation increases the oxygen reservoir in the lungs, extending
the period of safe apnea before significant arterial desaturation occurs.
5. Which electrolyte abnormality is most associated with peaked T waves on an
ECG?
A. Hypokalemia
B. Hyperkalemia
C. Hypocalcemia
D. Hypernatremia
Answer: B. Hyperkalemia
,Rationale: Hyperkalemia classically causes tall, peaked T waves and can
progress to conduction abnormalities and cardiac arrest.
6. Which opioid receptor is primarily responsible for analgesia produced by
morphine?
A. Mu
B. Delta
C. Kappa
D. Sigma
Answer: A. Mu
Rationale: Morphine primarily activates mu-opioid receptors, producing
analgesia, sedation, respiratory depression, and other opioid effects.
7. Which drug 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 that rapidly reverses
opioid-induced respiratory and central nervous system depression.
8. Which neuromuscular blocker is classified as a depolarizing agent?
A. Rocuronium
B. Vecuronium
C. Cisatracurium
D. Succinylcholine
Answer: D. Succinylcholine
Rationale: Succinylcholine produces persistent depolarization at the
neuromuscular junction, resulting in skeletal muscle paralysis.
, 9. Which monitoring modality provides continuous information about exhaled
carbon dioxide?
A. Pulse oximetry
B. Capnography
C. Electrocardiography
D. Bispectral monitoring
Answer: B. Capnography
Rationale: Capnography measures and displays exhaled carbon dioxide and
provides important information about ventilation and airway integrity.
10. What is the most important immediate treatment for severe hypoxemia
caused by airway obstruction?
A. Administer a diuretic
B. Increase intravenous fluids
C. Establish and maintain airway patency
D. Administer a beta blocker
Answer: C. Establish and maintain airway patency
Rationale: Airway obstruction prevents effective ventilation and oxygenation, so
restoring airway patency is the immediate priority.
11. Which anesthetic induction agent is generally associated with cardiovascular
stability?
A. Propofol
B. Etomidate
C. Thiopental
D. Midazolam
Answer: B. Etomidate
Rationale: Etomidate generally produces less cardiovascular depression than
many other induction agents and is often considered when hemodynamic
stability is important.
