1. A patient under general anesthesia develops a sudden increase in end-tidal
carbon dioxide, tachycardia, muscle rigidity, and hyperthermia. Which
condition should be suspected?
A. Neuroleptic malignant syndrome
B. Thyroid storm
C. Malignant hyperthermia
D. Serotonin syndrome
Answer: Malignant hyperthermia
Rationale: Malignant hyperthermia is an acute hypermetabolic reaction
associated with certain anesthetic agents, characterized by rapidly increasing
CO₂ production, muscle rigidity, tachycardia, and hyperthermia.
2. Which medication is the primary specific treatment for malignant
hyperthermia?
A. Amiodarone
B. Dantrolene
,C. Epinephrine
D. Calcium chloride
Answer: Dantrolene
Rationale: Dantrolene reduces calcium release from skeletal-muscle
sarcoplasmic reticulum and is the specific treatment for malignant
hyperthermia.
3. Which component of the preoperative assessment is most important for
identifying a potentially difficult airway?
A. Serum sodium
B. Mallampati classification
C. Hemoglobin concentration
D. Urine output
Answer: Mallampati classification
Rationale: Mallampati classification evaluates the visibility of oropharyngeal
structures and contributes to assessment of potential difficulty with
laryngoscopy and intubation.
4. Which physiologic change is most characteristic of spinal anesthesia?
A. Increased systemic vascular resistance
B. Sympathetic blockade with vasodilation
C. Increased cardiac preload
D. Increased venous return
Answer: Sympathetic blockade with vasodilation
Rationale: Spinal anesthesia blocks sympathetic nerve fibers, producing
vasodilation, reduced venous return, and potentially hypotension.
5. Which local anesthetic is generally associated with the greatest concern for
cardiotoxicity?
A. Lidocaine
B. Chloroprocaine
,C. Bupivacaine
D. Mepivacaine
Answer: Bupivacaine
Rationale: Bupivacaine has significant cardiotoxic potential, particularly when
administered intravascularly or in excessive doses.
6. A patient develops hypotension and bradycardia shortly after induction of
anesthesia. Which medication is most appropriate when clinically significant
bradycardia is contributing to the instability?
A. Atropine
B. Furosemide
C. Nitroglycerin
D. Protamine
Answer: Atropine
Rationale: Atropine blocks muscarinic receptors and increases heart rate,
making it useful for clinically significant vagally mediated bradycardia.
7. Which neuromuscular blocker is classified as a depolarizing agent?
A. Rocuronium
B. Vecuronium
C. Cisatracurium
D. Succinylcholine
Answer: Succinylcholine
Rationale: Succinylcholine is a depolarizing neuromuscular blocker that produces
rapid-onset, short-duration paralysis.
8. Which reversal agent directly encapsulates steroidal neuromuscular
blocking agents such as rocuronium?
A. Neostigmine
B. Sugammadex
, C. Atropine
D. Naloxone
Answer: Sugammadex
Rationale: Sugammadex forms complexes with steroidal neuromuscular
blockers, particularly rocuronium and vecuronium, facilitating rapid reversal.
9. Which monitoring method provides continuous information about oxygen
saturation?
A. Capnography
B. Pulse oximetry
C. Electrocardiography
D. Spirometry
Answer: Pulse oximetry
Rationale: Pulse oximetry continuously estimates arterial oxygen saturation and
provides information about oxygenation.
10.What does end-tidal carbon dioxide primarily reflect during controlled
ventilation?
A. Arterial oxygen content
B. Hemoglobin concentration
C. Ventilation and CO₂ elimination
D. Renal bicarbonate production
Answer: Ventilation and CO₂ elimination
Rationale: End-tidal CO₂ provides a useful estimate of alveolar CO₂ and is an
important indicator of ventilation and changes in pulmonary perfusion.
11.Which ventilator parameter represents the amount of air delivered with
each mechanical breath?
A. Respiratory rate
B. Tidal volume
