Endotracheal Intubation (ETI) and Rapid Sequence Anesthesia (RSA) - MCQs
1 * What is the primary purpose of endotracheal intubation (ETI)?
a) To administer intravenous medications.
b) To monitor the patient's heart rate.
c) To maintain a patent airway.
d) To provide supplemental oxygen via nasal cannula.
Answer: c)
2* Which of the following is NOT a primary indication for endotracheal intubation?
a) Airway protection from gastric aspiration.
b) Routine oxygen administration for mild hypoxemia.
c) Facilitation of ventilation in respiratory failure.
d) Administration of general anesthesia during surgery.
Answer: b)
3 * Severe upper airway edema (angioedema) is an indication for ETI due to:
a) Increased carbon dioxide levels.
b) Risk of airway obstruction.
c) Need for frequent suctioning.
d) Patient comfort.
Answer: b)
4 * Which of the following is considered an essential tool for endotracheal intubation?
a) Nasal cannula.
b) Pulse oximeter.
c) Endotracheal tube (ETT).
d) Blood pressure cuff.
Answer: c)
5 * What is the purpose of the stylet used during endotracheal intubation?
a) To inflate the cuff of the ETT.
b) To connect the ETT to the ventilator.
c) To assist with shaping the ETT for easier insertion.
d) To measure the depth of ETT insertion.
Answer: c)
6 * Confirmation of correct endotracheal tube placement relies heavily on:
a) Observing chest rise and fall.
b) Palpating for breath sounds over the abdomen.
c) End-tidal CO2 detection.
d) Monitoring the patient's heart rate.
Answer: c)
7* What is the purpose of the bag-valve-mask (BVM) during the ETI procedure?
a) To administer sedative medications.
b) For preoxygenation and ventilation.
c) To secure the endotracheal tube.
d) To suction airway secretions.
Answer: b)
8* The Mallampati score is used in patient assessment to evaluate:
a) Lung compliance.
b) Cardiac function.
c) Airway anatomy.
d) Neurological status.
Answer: c)
9* What is the primary goal of preoxygenation before endotracheal intubation?
a) To lower the patient's heart rate.
b) To increase the patient's blood pressure.
c) To replace nitrogen in the lungs with oxygen, extending safe apnea time.
d) To sedate the patient.
Answer: c)
10* The "sniffing" position is used to:
a) Improve venous return to the heart.
b) Facilitate bag-valve-mask ventilation.
c) Align the oral, pharyngeal, and laryngeal axes for better visualization.
d) Prevent aspiration.
Answer: c)
11* During the steps of performing ETI, visualization of what anatomical structure is crucial for successful tube insertion?
a) The epiglottis.
b) The trachea.
c) The vocal cords.
d) The esophagus.
Answer: c)
12* Which of the following is a method to confirm endotracheal tube placement?
a) Palpation of the carotid pulse.
b) Auscultation of bowel sounds.
c) Bilateral chest auscultation.
d) Observing pupillary response.
Answer: c)
13* What is the purpose of securing the endotracheal tube after successful placement?
a) To prevent infection.
b) To maintain the tube's position and prevent accidental dislodgement.
c) To allow for easier suctioning.
d) To monitor end-tidal CO2 levels.
Answer: b)
14 * A bougie or introducer is considered an optional tool for ETI and is primarily used for:
a) Routine intubations.
b) Difficult intubations.
c) Confirming tube placement.
d) Preoxygenation.
Answer: b)
