Question

Which is an acceptable method of selecting an appropriately sized oropharyngeal airway?

a) Measure from the earlobe to the corner of the mouth.
b) Measure from the nose to the middle of the chest.
c) Measure from the chin to the Adam's apple.
d) Measure from the corner of the mouth to the angle of the jaw.

Answer 1

The acceptable method of selecting an appropriately sized oropharyngeal airway is a) Measure from the earlobe to the corner of the mouth. It ensures a proper fit that maintains an open airway without causing obstruction or trauma.

Step-by-step explanation:

An appropriately sized oropharyngeal airway is crucial for patient safety and comfort when maintaining an open airway in unconscious or semi-conscious patients. The correct method for selecting a properly sized oropharyngeal airway is a) Measure from the earlobe to the corner of the mouth. This measurement ensures that the oropharyngeal airway fits from the oral cavity to the oropharynx without causing obstruction or displacing the tongue backwards which could obstruct the airway or cause trauma to the airway.

It is important to note the other methods listed (b, c, d) do not provide accurate measurements for an oropharyngeal airway size selection. An incorrect size can lead to ineffective ventilation or even injury to the patient, thus highlighting the importance of proper sizing.
