Q1.
A patient with a history of chronic opioid use is scheduled for surgery. Which
pharmacodynamic principle best explains the need for higher anesthetic doses to achieve
the same effect?
A. Downregulation of opioid receptors B. Upregulation of hepatic enzymes
C. Increased plasma protein binding D. Decreased blood-brain barrier
permeability
Correct: A - Downregulation of opioid receptors
Rationale:Chronic opioid exposure leads to receptor desensitization and downregulation,
requiring higher doses for equivalent effect (tolerance). Upregulation of enzymes (B) is
pharmacokinetic, not pharmacodynamic. Protein binding (C) and BBB permeability (D) are
also pharmacokinetic factors.
Q2.
Which physiological mechanism primarily accounts for the increased oxygen
consumption observed in patients with malignant hyperthermia?
A. Uncoupling of oxidative phosphorylation B. Increased ATP hydrolysis by muscle
in mitochondria contraction
C. Stimulation of the sympathetic nervous D. Enhanced glycolysis in the liver
system
Correct: A - Uncoupling of oxidative phosphorylation in mitochondria
Rationale:In malignant hyperthermia, uncontrolled calcium release causes sustained muscle
contraction and uncoupling of oxidative phosphorylation, leading to excessive heat and
oxygen consumption. While muscle contraction (B) occurs, the primary metabolic
derangement is mitochondrial uncoupling. Sympathetic stimulation (C) and hepatic glycolysis
(D) are secondary.
Q3.
A difficult airway is anticipated. Which airway assessment finding is most predictive of
difficult laryngoscopy?

A. Mallampati class III B. Thyromental distance of 5 cm
C. Interincisor gap of 4 cm D. Neck circumference of 40 cm
Correct: A - Mallampati class III
Rationale:Mallampati class III is a strong predictor of difficult laryngoscopy due to reduced
pharyngeal visualization. Thyromental distance (B) and interincisor gap (C) are also
predictors but less sensitive. Neck circumference (D) is associated with difficult mask
ventilation, not laryngoscopy.
Q4.
Which anesthesia equipment safety feature is designed to prevent delivery of a hypoxic
gas mixture?
A. Oxygen failure safety valve B. Pin index safety system
C. Oxygen ratio monitor controller D. Adjustable pressure limiting valve
Correct: C - Oxygen ratio monitor controller
Rationale:The oxygen ratio monitor controller (ORMC) ensures a minimum oxygen
concentration (typically 25%) by linking nitrous oxide and oxygen flow, preventing hypoxic
mixtures. The oxygen failure safety valve (A) shuts off N2O when O2 is lost, but does not
prevent hypoxic mixtures during normal operation. The pin index (B) prevents wrong cylinder
attachment, and APL (D) controls circuit pressure.
Q5.
A patient receiving neostigmine for reversal of neuromuscular blockade develops
bradycardia. Which mechanism explains this effect?
A. Direct stimulation of muscarinic receptors B. Inhibition of acetylcholinesterase leading
to acetylcholine accumulation
C. Stimulation of nicotinic receptors at the D. Blockade of sympathetic ganglia
neuromuscular junction
Correct: B - Inhibition of acetylcholinesterase leading to acetylcholine accumulation
Rationale:Neostigmine inhibits acetylcholinesterase, increasing acetylcholine at muscarinic
receptors, causing bradycardia. It does not directly stimulate muscarinic receptors (A).
Nicotinic stimulation (C) affects skeletal muscle, not heart rate. Ganglionic blockade (D) is not
a neostigmine effect.
