1. Which factor most directly increases the risk of difficult mask ventilation in an
adult patient?
A. Age younger than 30 years
B. Normal body habitus
C. Obesity
D. Absence of facial hair
Answer: C. Obesity
Rationale: Obesity is associated with reduced functional residual capacity,
increased upper-airway soft tissue, and greater difficulty maintaining effective
mask ventilation.
2. What is the primary purpose of preoxygenation before induction of general
anesthesia?
A. Increase hemoglobin concentration
B. Replace alveolar nitrogen with oxygen
,C. Decrease pulmonary blood flow
D. Prevent postoperative nausea
Answer: B. Replace alveolar nitrogen with oxygen
Rationale: Preoxygenation creates an oxygen reservoir in the lungs and
increases the time before arterial oxygen desaturation occurs during apnea.
3. Which anesthetic agent is most commonly associated with dose-dependent
myocardial depression and hypotension?
A. Propofol
B. Ketamine
C. Nitrous oxide
D. Etomidate
Answer: A. Propofol
Rationale: Propofol produces dose-dependent vasodilation and myocardial
depression, making hypotension particularly likely in hypovolemic or
hemodynamically fragile patients.
4. Which medication is most appropriate for treating severe opioid-induced
respiratory depression?
A. Flumazenil
B. Naloxone
C. Atropine
D. Sugammadex
Answer: B. Naloxone
Rationale: Naloxone is an opioid antagonist that reverses opioid-induced
respiratory and central nervous system depression.
5. Which finding is most characteristic of malignant hyperthermia?
A. Progressive muscle rigidity and rapidly increasing end-tidal carbon dioxide
B. Gradual decrease in body temperature
,C. Isolated hypertension without metabolic abnormalities
D. Persistent bradycardia without muscle abnormalities
Answer: A. Progressive muscle rigidity and rapidly increasing end-tidal carbon
dioxide
Rationale: Early manifestations of malignant hyperthermia include rapidly
increasing carbon dioxide production, tachycardia, muscle rigidity, acidosis, and
hyperkalemia.
6. What is the specific treatment for malignant hyperthermia?
A. Calcium gluconate
B. Dantrolene
C. Protamine
D. Methylene blue
Answer: B. Dantrolene
Rationale: Dantrolene directly reduces calcium release from the sarcoplasmic
reticulum and is the definitive pharmacologic treatment for malignant
hyperthermia.
7. Which ventilator strategy is generally preferred for patients receiving
mechanical ventilation because of acute respiratory distress syndrome?
A. Very large tidal volumes
B. Low tidal volume based on predicted body weight
C. Zero positive end-expiratory pressure
D. Routine hyperventilation to very low carbon dioxide levels
Answer: B. Low tidal volume based on predicted body weight
Rationale: Lung-protective ventilation using low tidal volumes helps reduce
ventilator-induced lung injury in patients with acute respiratory distress
syndrome.
8. Which hemodynamic variable is most directly related to left ventricular
preload?
, A. End-diastolic volume
B. Systemic vascular resistance
C. Ejection fraction
D. Mean arterial pressure
Answer: A. End-diastolic volume
Rationale: Left ventricular preload is closely related to myocardial fiber stretch
at the end of diastole, which is reflected clinically by end-diastolic volume.
9. Which medication is a direct-acting alpha-1 adrenergic agonist commonly
used to treat anesthesia-associated hypotension?
A. Phenylephrine
B. Epinephrine
C. Dobutamine
D. Milrinone
Answer: A. Phenylephrine
Rationale: Phenylephrine primarily stimulates alpha-1 receptors, producing
vasoconstriction and increasing systemic vascular resistance and arterial blood
pressure.
10. Which condition is most likely to produce a widened pulse pressure?
A. Severe aortic regurgitation
B. Cardiac tamponade
C. Hypovolemic shock
D. Severe mitral stenosis
Answer: A. Severe aortic regurgitation
Rationale: Aortic regurgitation increases systolic stroke volume while lowering
diastolic pressure, producing a widened pulse pressure.
11. Which local anesthetic has the greatest association with cardiotoxicity when
systemic toxicity occurs?
