AT&T TKT II FINAL EXAM QUESTIONS
WITH 100% CORRECT ANSWERS.
What is an advantage of an EZ blocker over a DLT?
Easier placement
Which is an Absolute Contraindication to DLT placement.
Difficult airway
RSI
Dislodgeable mass
Upper lobectomy
Dislodgeable mass
What is the best method to confirm placement of DLT?
FOB
What is the anatomical length of the Right Main Bronchus?
2.5cm
What is the anatomical length of the Left main bronchus?
5cm
You have successfully placed a left‐sided double‐lumen endotracheal tube.
You now want to ventilate only the right lung.
Which lumen should be clamped?
Blue Lumen
During one‐lung ventilation with a left‐sided DLT, the surgeon is operating on the left
lung.
,The patient’s oxygenation is suboptimal. Which of the following best describes the
technique to improve oxygenation?
CPAP to Nondependent PEEP to dependent
What best explains why the left‐sided DLT is more comm
Left main bronchus is longer
After one‐lung ventilation is no longer required, you want to re‐establish two‐lung
ventilation through a left‐sided DLT.
How would you do so?
Unclamp all and deflate bronchial cuff
Shortly after positioning the patient for a left thoracotomy, peak inspiratory pressures
increase and oxygenation worsens.
Auscultation reveals absent breath sounds on the right but present on the left.
Which of the following is the most likely cause?
Tube advanced into Left main bronchus occluding right main bronchus
Which of the following fiberoptic findings most definitively confirms that the bronchial
lumen is correctly positioned in the left main bronchus?
Bronchial cuff sitting in the left main bronchus, just below the carina, with a clearly visible left
upper lobe orifice
Where is the appropriate site to make incision when performing surgical cricothyrotomy?
Midline of Cricoid Cartilage
Which scenarios best indicates the need for an emergency cricothyrotomy (2)
Oropharyngeal bleeding & upper airway obstruction
Which is an absolute contraindication for an emergency circothyrotomy?
Lack of anatomical landmarks
, Coagulopathy
Unstable C-spine
Radiation to neck
Lack of anatomical landmarks
describes the sequence of steps in performing a surgical cricothyrotomy?
1. Palpate Cricothyroid membrane
2. Horizontal incision
3. Vertical incision
4. Boujie
5. Dilate
6. Tube
In a cricothyrotomy procedure, which anatomical structure, palpable in the midline of the
neck, lies between the "Adam's apple" and the ring-shaped cartilage below, and
is characterized by its soft and pliable nature?
Cricoid Cartilage
How does a light wand primarily facilitate endotracheal intubation?
transillumination
For which patients would the use of a light wand be most useful?
unstable C spine but normal anatomy
What is a contraindication to intubation facilitated by a light wand?
Obesity
When preparing a patient’s airway for awake fiberoptic intubation, which of the following
is most important?
adequate topical anesthesia of airway
