1. A patient develops hypotension and tachycardia shortly after induction of
general anesthesia. The most appropriate initial approach is to:
A. Administer a long-acting beta blocker
B. Assess the likely cause while supporting airway, breathing, and circulation
C. Immediately administer a diuretic
D. Delay treatment until laboratory results return
Answer: B. Assess the likely cause while supporting airway, breathing, and
circulation
Rationale: Perioperative hypotension requires prompt assessment and
simultaneous stabilization of oxygenation, ventilation, and circulation. Common
causes include anesthetic-induced vasodilation, hypovolemia, bleeding, reduced
cardiac output, and anaphylaxis.
2. Which receptor is primarily responsible for the bronchodilatory effect of
inhaled albuterol?
A. Alpha-1
B. Alpha-2
,C. Beta-2
D. Beta-1
Answer: C. Beta-2
Rationale: Activation of beta-2 adrenergic receptors in bronchial smooth muscle
increases intracellular cyclic AMP and produces bronchodilation.
3. Which anesthetic agent is most associated with dose-dependent myocardial
depression?
A. Ketamine
B. Nitrous oxide
C. Propofol
D. Midazolam
Answer: C. Propofol
Rationale: Propofol commonly causes dose-dependent decreases in systemic
vascular resistance and myocardial contractility, potentially producing
significant hypotension, particularly in hypovolemic patients.
4. A patient with severe hyperkalemia develops a widened QRS complex.
Which medication should be administered promptly to stabilize the cardiac
membrane?
A. Furosemide
B. Regular insulin alone
C. Sodium bicarbonate in every case
D. Intravenous calcium
Answer: D. Intravenous calcium
Rationale: Intravenous calcium stabilizes the myocardial membrane and reduces
the immediate risk of malignant dysrhythmias. It does not directly lower serum
potassium.
5. Which ventilation strategy is generally preferred for patients with acute
respiratory distress syndrome?
,A. Very high tidal volumes
B. Low tidal volumes based on predicted body weight
C. Zero PEEP
D. Routine hyperventilation
Answer: B. Low tidal volumes based on predicted body weight
Rationale: Lung-protective ventilation with low tidal volumes reduces ventilator-
induced lung injury in acute respiratory distress syndrome. Appropriate PEEP is
also commonly used.
6. Which local anesthetic is particularly associated with severe cardiotoxicity
when systemic toxicity occurs?
A. Lidocaine
B. Chloroprocaine
C. Bupivacaine
D. Procaine
Answer: C. Bupivacaine
Rationale: Bupivacaine has a relatively high affinity for cardiac sodium channels
and can cause severe ventricular dysrhythmias and cardiovascular collapse
during systemic toxicity.
7. The earliest clinical manifestations of local anesthetic systemic toxicity often
involve:
A. Renal failure
B. Hepatic failure
C. Central nervous system symptoms
D. Pulmonary edema
Answer: C. Central nervous system symptoms
Rationale: Early toxicity may produce circumoral numbness, tinnitus, metallic
taste, dizziness, agitation, or seizures before severe cardiovascular toxicity
develops.
, 8. Which medication is a competitive antagonist at opioid receptors?
A. Flumazenil
B. Naloxone
C. Sugammadex
D. Atropine
Answer: B. Naloxone
Rationale: Naloxone is an opioid receptor antagonist used to reverse opioid-
induced respiratory and central nervous system depression.
9. Which medication reverses the effects of benzodiazepines?
A. Naloxone
B. Neostigmine
C. Flumazenil
D. Physostigmine
Answer: C. Flumazenil
Rationale: Flumazenil competitively antagonizes benzodiazepine activity at the
GABA-A receptor complex.
10.Which neuromuscular blocking agent is classified as a depolarizing agent?
A. Rocuronium
B. Vecuronium
C. Cisatracurium
D. Succinylcholine
Answer: D. Succinylcholine
Rationale: Succinylcholine produces persistent depolarization of the
neuromuscular junction and is the primary depolarizing neuromuscular blocker
used in clinical anesthesia.
11.Which neuromuscular blocking agent undergoes Hofmann elimination?
