ABA Airway Management 2

Question 1

What is the primary advantage of video laryngoscopy compared to direct laryngoscopy?

Accepted Answer

Improved glottic visualization without requiring direct line-of-sight alignment

Answer

Consistently faster time to intubation

Answer

No need for cervical spine precautions in trauma

Answer

Eliminates the need for neuromuscular blockade

Question 2

The intubating laryngeal mask airway (ILMA/LMA Fastrach) is primarily designed to:

Accepted Answer

Facilitate blind or fiberoptic-assisted tracheal intubation through the device

Answer

Serve as a definitive surgical airway in CICO scenarios

Answer

Provide higher oropharyngeal seal pressures than a standard LMA

Answer

Continuously monitor end-tidal CO2 levels

Question 3

During awake fiberoptic intubation, which topical anesthetic agent is most commonly used to anesthetize the airway mucosa?

Accepted Answer

Lidocaine 4%

Answer

Bupivacaine 0.5%

Answer

Tetracaine 2%

Answer

Ropivacaine 0.75%

Question 4

The cricothyroid membrane is the preferred site for emergency surgical airway access for which of the following reasons?

Accepted Answer

It is relatively avascular and lies just below the skin surface

Answer

It is the widest portion of the trachea

Answer

It contains no cartilage

Answer

It is visible on standard chest radiography

Question 5

Which of the following best describes the technique of retrograde intubation?

Accepted Answer

Advancing a guide wire cephalad through the cricothyroid membrane and out the mouth to railroad an endotracheal tube

Answer

Advancing an endotracheal tube blindly through the nasopharynx

Answer

Using a bronchoscope inserted from a tracheostomy stoma to visualize cords from below

Answer

Directing an endotracheal tube with the bevel facing posteriorly

Question 6

External laryngeal manipulation using the BURP maneuver involves applying pressure in which direction on which structure?

Accepted Answer

Backward, Upward, and Rightward pressure on the thyroid cartilage

Answer

Backward, Upward, and Rightward pressure on the cricoid cartilage

Answer

Downward and Leftward pressure on the thyroid cartilage

Answer

Upward and forward pressure on the hyoid bone

Question 7

During awake fiberoptic intubation, superior laryngeal nerve blocks are performed to anesthetize which airway structures?

Accepted Answer

Supraglottic structures including the epiglottis and piriform fossae

Answer

Tracheal mucosa below the cords

Answer

Nasal mucosa and nasopharynx

Answer

The vocal cords and subglottic mucosa
