Anesthesia and Critical Care, 1st Edition

Jeremy S. Heiner & Mark Gabot & Sassoon Michael Elisha
,Chapter 1: Airway and Surgical Fire
1. Which of the following is the most common cause of airway obstruction in an
unconscious patient?
A) Foreign body aspiration
B) Laryngeal edema
C) Tongue displacement
D) Bronchospasm
Answer: C) Tongue displacement
Rationale: In unconscious patients, the tongue often relaxes and obstructs the airway,
making tongue displacement the most common cause of airway obstruction.
DIF: Moderate
TOP: Airway management
MSC: Respiratory
2. During a surgical procedure, the anesthesia provider notices a sudden rise in airway
pressure with absent breath sounds. What is the most appropriate immediate
action?
A) Administer a bronchodilator
B) Check for endotracheal tube displacement
C) Increase the oxygen flow rate
D) Suction the airway
Answer: B) Check for endotracheal tube displacement
Rationale: The most likely cause of a sudden rise in airway pressure with absent breath
sounds is endotracheal tube displacement or obstruction. Immediate assessment and
repositioning of the tube are necessary.
DIF: Moderate
TOP: Airway management
MSC: Respiratory
3. What is the most appropriate method to confirm proper placement of an
endotracheal tube during intubation?
A) Monitoring the patient's pulse oximetry
B) Visualizing tube placement with a bronchoscope
C) Checking for bilateral breath sounds
D) Observing chest rise and fall
Answer: C) Checking for bilateral breath sounds
Rationale: Confirming proper placement of the endotracheal tube is most commonly
done by auscultating bilateral breath sounds to ensure the tube is correctly positioned in
the trachea and not in the esophagus.
DIF: Easy
TOP: Airway management
MSC: Respiratory
,4. Which of the following is the most important prevention strategy for surgical fires
during anesthesia?
A) Using non-flammable drapes
B) Adequately positioning the patient
C) Maintaining adequate oxygen levels
D) Ensuring proper grounding of electrical equipment
Answer: D) Ensuring proper grounding of electrical equipment
Rationale: Electrical fires are a common cause of surgical fires, and ensuring proper
grounding of electrical equipment helps reduce the risk of sparks that could ignite
flammable materials in the operating room.
DIF: Hard
TOP: Surgical fire prevention
MSC: Safety
5. In the event of a surgical fire, what is the first priority action?
A) Extinguish the fire
B) Remove the patient from the operating room
C) Shut off the oxygen supply
D) Alert the surgical team
Answer: C) Shut off the oxygen supply
Rationale: Oxygen can fuel the fire and exacerbate the situation. Shutting off the oxygen
supply should be the first priority to prevent further escalation of the fire.
DIF: Moderate
TOP: Surgical fire management
MSC: Safety
6. A patient undergoing surgery has a sudden loss of consciousness. What is the first
step in managing a potential airway obstruction?
A) Administer oxygen
B) Perform a jaw-thrust maneuver
C) Insert a nasopharyngeal airway
D) Position the patient in a lateral position
Answer: B) Perform a jaw-thrust maneuver
Rationale: The jaw-thrust maneuver is the most effective first step to open the airway in
an unconscious patient. This technique should be used before other interventions like
inserting an airway.
DIF: Easy
TOP: Airway management
MSC: Respiratory
7. What is the primary risk factor for airway fire during laser surgery?
A) High oxygen concentrations
B) Poor ventilation
C) Excessive fluid infusion
D) Hypothermia
Answer: A) High oxygen concentrations
Rationale: High oxygen concentrations are a primary risk factor for surgical fires,
particularly during laser surgery, as oxygen can act as an accelerant when exposed to
sparks or heat.
, DIF: Moderate
TOP: Surgical fire prevention
MSC: Safety
8. During intubation, what is the purpose of the rapid-sequence induction (RSI)
technique?
A) To reduce the risk of aspiration
B) To induce anesthesia more quickly
C) To ensure faster intubation
D) To improve airway ventilation
Answer: A) To reduce the risk of aspiration
Rationale: Rapid-sequence induction (RSI) is used to minimize the risk of aspiration by
rapidly inducing anesthesia and securing the airway in patients at high risk for aspiration.
DIF: Moderate
TOP: Airway management
MSC: Respiratory
9. Which of the following is the most common cause of post-intubation hypoxia?
A) Pulmonary embolism
B) Endotracheal tube displacement
C) Bronchospasm
D) Airway obstruction
Answer: B) Endotracheal tube displacement
Rationale: Post-intubation hypoxia is most often caused by endotracheal tube
displacement, which can lead to inadequate ventilation and oxygenation.
DIF: Moderate
TOP: Airway management
MSC: Respiratory
10. In the case of a surgical fire, which of the following should be removed from the
operating room immediately?
A) The patient’s clothing
B) The surgical drapes
C) Any alcohol-based prep solutions
D) The surgical instruments
Answer: C) Any alcohol-based prep solutions
Rationale: Alcohol-based prep solutions are flammable and should be removed from the
area during a surgical fire to prevent the fire from spreading.
DIF: Hard
TOP: Surgical fire management
MSC: Safety
11. What is the most appropriate method to assess the depth of anesthesia during
surgery?
A) Monitoring the heart rate
B) Using a Bispectral Index (BIS) monitor
C) Observing the patient's reflexes
D) Measuring blood pressure
Answer: B) Using a Bispectral Index (BIS) monitor
Rationale: The BIS monitor provides a reliable measurement of the depth of anesthesia
