CERTIFICATION COMPREHENSIVE REVIEW WITH COMPLETE EXAM
QUESTIONS AND CORRECT VERIFIED ANSWERS | ALREADY GRADED A+
1. A 68-year-old patient with severe aortic stenosis is scheduled for major
abdominal surgery and has preserved sinus rhythm but limited functional
capacity. During induction, the blood pressure suddenly falls and the ECG
demonstrates new ST-segment depression. Which anesthetic management
strategy is most appropriate for maintaining coronary perfusion and
minimizing myocardial ischemia?
A. Reduce venous return to decrease ventricular workload
B. Produce controlled vasodilation to decrease afterload substantially
C. Maintain preload and systemic vascular resistance while avoiding
significant tachycardia and hypotension
D. Allow marked tachycardia to increase cardiac output despite reduced
filling time
Answer: C
2. A patient with severe COPD is undergoing general anesthesia and
mechanical ventilation. The capnogram demonstrates a prolonged
expiratory phase with a sloping alveolar plateau, and the expiratory
waveform does not return to baseline before the next breath. Which
ventilatory abnormality is most likely present?
A. Expiratory airflow limitation with incomplete alveolar emptying and
possible auto-PEEP
B. Complete airway obstruction from a foreign body
C. Isolated pulmonary shunt without airflow obstruction
D. Increased inspired carbon dioxide from exhausted absorbent
Answer: A
3. A 44-year-old patient develops rapidly increasing end-tidal carbon dioxide,
generalized muscle rigidity, tachycardia, metabolic acidosis, and rising core
, temperature shortly after exposure to sevoflurane and succinylcholine.
Which intervention is most important after immediately discontinuing the
triggering agents?
A. Administer flumazenil and increase anesthetic depth
B. Give protamine and discontinue intravenous fluids
C. Administer naloxone and continue volatile anesthesia
D. Administer dantrolene while providing aggressive supportive
management
Answer: D
4. A hemodynamically unstable patient requires urgent induction of general
anesthesia. The anesthesia provider wants an induction agent that
produces relatively little direct myocardial depression and is less likely than
propofol to cause significant cardiovascular collapse. Which agent best fits
this objective?
A. Etomidate
B. Methohexital
C. Thiopental
D. Propofol
Answer: A
5. A patient undergoing general anesthesia develops an abrupt increase in
peak airway pressure while plateau pressure remains relatively unchanged.
Breath sounds are present bilaterally, and the capnogram remains
recognizable. Which mechanism most directly explains this ventilator
change?
A. Increased airway resistance
B. Severe reduction in functional residual capacity
C. Increased pulmonary capillary permeability
D. Reduced pulmonary compliance
Answer: A
, 6. A patient with known coronary artery disease becomes tachycardic and
hypertensive during surgical stimulation and subsequently develops ST-
segment depression. Which physiologic relationship best explains the
development of myocardial ischemia?
A. Reduced cardiac work has lowered myocardial oxygen consumption
B. Coronary blood flow has increased sufficiently to eliminate ischemia
C. Myocardial oxygen demand has increased relative to available oxygen
supply
D. Myocardial oxygen supply has increased more rapidly than demand
Answer: C
7. During a difficult intubation, a patient cannot be intubated with direct
laryngoscopy but maintains oxygen saturation after placement of a
supraglottic airway. Which principle should guide further airway
management?
A. Administer additional neuromuscular blockade without reassessing
ventilation
B. Prioritize oxygenation and follow an established difficult-airway rescue
strategy
C. Remove the supraglottic airway immediately even though oxygenation is
adequate
D. Continue repeated traumatic laryngoscopy attempts until intubation
succeeds
Answer: B
8. A patient receiving high-dose fentanyl develops apnea, profound sedation,
pinpoint pupils, and severe hypoventilation. Which medication most
directly antagonizes opioid-mediated respiratory depression?
A. Sugammadex
B. Physostigmine
C. Flumazenil
D. Naloxone
, Answer: D
9. A patient with severe pulmonary hypertension is undergoing general
anesthesia. Which physiologic change should be particularly avoided
because it can markedly increase pulmonary vascular resistance and
precipitate right ventricular failure?
A. Hypoxemia with hypercarbia and acidosis
B. Maintenance of normal acid-base status
C. Hyperoxia
D. Mild hypocapnia
Answer: A
10. An arterial blood gas obtained during anesthesia shows pH 7.24, PaCO₂ 61
mmHg, and bicarbonate 26 mEq/L. The patient has no significant metabolic
disorder. Which interpretation is most appropriate?
A. Chronic respiratory alkalosis
B. Metabolic alkalosis with respiratory compensation
C. Acute respiratory acidosis
D. Metabolic acidosis with respiratory compensation
Answer: C
11. A patient with a documented history of malignant hyperthermia
susceptibility requires urgent surgery. Which anesthetic technique most
effectively avoids exposure to known triggering anesthetic agents?
A. Desflurane combined with nitrous oxide
B. Total intravenous anesthesia using nontriggering medications
C. Isoflurane at a very low concentration
D. Sevoflurane combined with succinylcholine
Answer: B
12. A patient becomes profoundly hypotensive following induction of general
anesthesia. Heart rate is adequate, preload appears reasonable, and
systemic vascular resistance is markedly reduced. Which pharmacologic
intervention most directly addresses the primary hemodynamic problem?
