Apex Airway Management Domain Exam
(Latest 2026/2027 Update) Questions with
Verified Answers 100% Correct {Graded A}.
Which conditions are associated with the use of smaller diameter endotracheal tubes?
(Select 2)
-More tracheal mucosal trauma
-Increased incidence of sore throat
-Higher work of breathing
-Increased airway resistance - correct answer Higher work of breathing
Increased airway resistance
Which anthropometric measure provides the MOST predictive ability for difficult
intubation?
-Body mass index
-Waist circumference
-Neck circumference
-Body weight - correct answer Neck circumference
, (A neck circumference greater than 17 inches is even more valuable than the BMI for
this prediction.)
Which airway assessment finding suggests a possible anterior displaced larynx?
-Inflexible mandibular space
-Thyromental distance 7.5 cm
-Sternomental distance 13.5 cm
-Relatively short upper incisors - correct answer Inflexible mandibular space
(The so-called anterior larynx is associated with conditions that reduce the
submandibular space so that the tongue cannot be adequately displaced during
laryngoscopy. These conditions include small mandible, lack of submandibular
compliance due to a mass, or previous head/neck radiation treatment. Thyromental
distance less than 6.5 cm is another indication of reduced mandibular space. A
sternomental distance less than 12.5 cm is associated with difficult intubation. This
measurement is taken with the head extended and mouth closed, so it also serves as a
partial assessment of neck mobility.)
