Question1

During intubation, problems with exposure of the glottic opening can be caused by which of the following?  (please check all that apply)

  anterior larynx

  prominent upper incisors

  large posteriorly located tongue

  micrognathia (small mandible)

Question 2

During an airway examination, a Mallampati classification I means that the examiner can see which of the following views?

  soft palate, fauces, uvula, pillars

  soft palate, fauces, uvula

  soft palate, uvular base

  hard palate only

TECHNIQUE FOR OROTRACHEAL INTUBATION

Question 3

Equipment needed for endotracheal intubation include:  (please check all that apply)

  a properly sized tracheal tube.

  laryngoscope.

  functioning suction catheter with Yankauer tip.

  means of delivering positive pressure ventilation.

PREOXYGENATION

Question 4

Preoxygenation with 100% O₂ and spontaneous ventilation with a tight-fitting face mask for 3-5 minutes can furnish oxygen reserve following apnea (in a patient without significant cardiopulmonary disease and a normal oxygen consumption).  How many minutes of oxygen reserve can such preoxygenation provide in the normal patient?

 2 minutes

  5 minutes

  10 minutes

  20 minutes

Question 5

Which sentence best describes the proper intubation techniques when using the curved (MacIntosh) blade?

  The blade is inserted into the vallecula and then lifted with an anterior movement, away from the upper teeth.  This movement is sometimes described as “lifting towards the patient’s feet”, which stretches the hypo-epiglottic ligament, thereby elevating the epiglottis and exposing the glottic opening

  The tip of the straight blade is passed beneath (posterior to) the laryngeal surface of the epiglottis, (thereby “picking up” the epiglottis). Anterior movement of the blade “lifting towards the patient’s feet”, away from the upper teeth, directly elevates the epiglottis and exposes the glottic opening

Question 6

True statements about the sniffing position include:  (please check all that apply)

  flex head forward on a pillow to place the plane of the face on the same level as the anterior chest wall (sternum).

  extend the neck, or "point the chin towards the ceiling".

  aligns pharyngeal and laryngeal axes.

  creates larger mouth opening.

Question 7

During intubation, when the vocal cords are under direct visualization, the endotracheal tube is inserted:

  between the cords, into the trachea.

  insert the tube through the cords until the cuff goes out of view.

  check the depth of insertion - typically 19-21 cm marks should be at the level of the teeth.

  remove the laryngoscope carefully to prevent damage to the teeth.

Question 8

Confirmation of endotracheal tube position is accomplished by:  (please check all that apply)

  confirm the presence of CO₂ with a chemical detector.

  alternatively, use a suction device to confirm placement in a large gas-containing space.

  watch for the chest rising symmetrically with each delivered breath.

  listen for bilateral and equal breath sounds over the chest.

Question 9

The purpose of Sellick's Maneuver (also known as cricoid pressure) is to:  (please check all that apply)

  occlude the pharynx.

  assist in the passage of an orogastric tube.

  aid in prevention of aspiration of gastric contents.

 prevent dental damage during intubation.

 assist in visualization of vocal cords during intubation by applying cranialwards pressure on the larynx.
