QUESTION 1
According to the American Society of Anesthesiologists (ASA) physical
status classification, how is a patient with mild systemic disease (such as
well-controlled essential hypertension or controlled type 2 diabetes
without systemic complications) classified?
• A. ASA I
• B. ASA II
• C. ASA III
• D. ASA IV
Correct Answer: B. ASA II
Detailed Rationale: ASA I denotes a normal, healthy patient; ASA II
indicates a patient with mild systemic disease that does not limit
functional capacity; ASA III represents severe systemic disease that
limits activity; and ASA IV denotes severe systemic disease that is a
constant threat to life.
QUESTION 2
What is considered the normal resting blood pressure range for an adult
patient according to standard clinical guidelines?
• A. Less than 120/80 mmHg
, • B. 130 to to 89 mmHg
• C. 140 to to 99 mmHg
• D. 160/100 mmHg or higher
Correct Answer: A. Less than 120/80 mmHg
Detailed Rationale: Normal adult blood pressure is defined as a systolic
pressure of less than 120 mmHg and a diastolic pressure of less than 80
mmHg, serving as the baseline parameter during preoperative patient
evaluation.
QUESTION 3
What is the primary immediate emergency management step when a
patient undergoing office-based sedation experiences a complete
laryngospasm?
• A. Immediate intravenous administration of a neuromuscular
blocker like succinylcholine
• B. Delivery of positive pressure ventilation with 100% oxygen
using a bag-valve-mask system
• C. Immediate endotracheal intubation through the vocal cords
without suctioning
• D. Administration of sublingual nitroglycerin to reduce pulmonary
vascular pressure
Correct Answer: B. Delivery of positive pressure ventilation with 100%
oxygen using a bag-valve-mask system
Detailed Rationale: The initial response to laryngospasm includes
establishing a patent airway, applying positive pressure ventilation with
,100% oxygen, and performing jaw thrust. If complete obstruction
persists, pharmacological intervention (succinylcholine or small-dose
propofol) may be required.
QUESTION 4
Which component of the standard electrocardiogram (ECG) waveform
represents ventricular depolarization?
• A. P wave
• B. QRS complex
• C. T wave
• D. U wave
Correct Answer: B. QRS complex
Detailed Rationale: The P wave corresponds to atrial depolarization,
the QRS complex represents ventricular depolarization preceding
contraction, and the T wave reflects ventricular repolarization.
QUESTION 5
What is the primary pharmacological action of adding a vasoconstrictor
(such as epinephrine) to local anesthetic solutions?
• A. To increase systemic absorption and lower local tissue pH
• B. To constrict local blood vessels, thereby reducing bleeding and
prolonging the duration of anesthesia
• C. To stimulate central nervous system respiration and prevent
sedation-induced apnea
, • D. To directly block neuromuscular transmission at the motor
endplate
Correct Answer: B. To constrict local blood vessels, thereby reducing
bleeding and prolonging the duration of anesthesia
Detailed Rationale: Vasoconstrictors decrease blood flow to the
injection site, which slows the systemic absorption of the local
anesthetic, keeps the drug concentrated near the nerve fibers longer,
and minimizes intraoperative bleeding.
QUESTION 6
When delivering supplemental oxygen via a nasal cannula during
outpatient oral surgery sedation, what is the typical recommended flow
rate range?
• A. 0.25 to 0.5 liters per minute
• B. 1 to 6 liters per minute
• C. 10 to 15 liters per minute
• D. 20 to 25 liters per minute
Correct Answer: B. 1 to 6 liters per minute
Detailed Rationale: A nasal cannula is a low-flow oxygen delivery device
typically set between 1 and 6 liters per minute, providing adequate
fraction of inspired oxygen (𝐹𝑖𝑂2 ) elevation during moderate sedation.
QUESTION 7
What is the standard concentration and route of epinephrine
administered for an acute, life-threatening anaphylactic reaction?
• A. 1:10,000 administered via slow intravenous push only
