Question 1

The LEMON mnemonic is used for predicting difficult direct laryngoscopy. What does the letter 'E' represent?

Accepted Answer

Evaluation of the 3-3-2 rule

Answer

In the LEMON airway assessment, 'E' stands for Evaluation of the 3-3-2 rule: ≥3 finger mouth opening, ≥3 finger thyromental distance, and ≥2 finger hyomental distance.

Question 2

Which laryngoscope blade design is recommended for patients with a long, floppy epiglottis?

Accepted Answer

Miller straight blade

Answer

The Miller straight blade is used to directly lift the epiglottis, providing better exposure in patients with a long, floppy epiglottis that obscures the glottis.

Question 3

During rapid sequence induction (RSI), cricoid pressure (Sellick maneuver) is applied to:

Accepted Answer

Compress the esophagus against the vertebral body to prevent passive regurgitation

Answer

Cricoid pressure compresses the esophagus between the cricoid cartilage and C6 vertebra to reduce the risk of passive regurgitation and pulmonary aspiration.

Question 4

The recommended cuff pressure for a standard endotracheal tube is:

Accepted Answer

20–30 cmH2O

Answer

ETT cuff pressure should be maintained at 20–30 cmH2O to seal the airway without compromising tracheal mucosal perfusion, which occurs above approximately 30 cmH2O.

Question 5

Which feature distinguishes a laryngeal mask airway (LMA) from an endotracheal tube?

Accepted Answer

The LMA sits in the hypopharynx over the laryngeal inlet and does not pass through the vocal cords

Answer

An LMA is a supraglottic airway device that seats in the hypopharynx over the laryngeal inlet; it does not pass through the cords and provides less aspiration protection than an ETT.
