Deck 5: Special Airways for Ventilation

Question 1

An oropharyngeal airway should only be used in patients who are conscious.

Answer 1

False

Question 2

The oropharyngeal airway is a simple airway adjunct that can be used to facilitate ventilation and removal of secretions.

Answer 2

False

Question 3

Since an EOA is inserted into the esophagus, the cuff at the distal end must be inflated during use to prevent air from entering the stomach.

Answer 3

True

Question 4

With an EGTA, the ventilation holes are along the proximal end of the tube

Question 5

It is essential to use the largest DLT appropriate for the patient since most complications associated with DLTs result from using small tubes.

C) laryngeal mask airway
D) esophageal gastric tube airway

Question 7

A(n) ____ can be used in patients with an intact gag reflex, unstable fractures of the mandible, trimus (lockjaw), or oral trauma.

A) nasopharyngeal airway
B) oropharyngeal airway
C) esophageal obturator airway
D) laryngeal mask airway

Question 8

The final selection of appropriate size of nasopharyngeal airway should be based on the ____.

A) width of the patient's nares

The cuff of an EOA is first inflated with ____ mL of air to check for cuff integrity and leaks.

A) 10 to 20
B) 20 to 30
C) 30 to 40
D) 40 to 50

Question 12

Which of the following is a distinct feature of the EGTA?

A) blind distal end

C) EOA
D) EGTA

Question 14

Which of the following patient groups should use size 4 LMA?

A) Children between 30 to 50 kg and small adults
B) Adults 50 to 70 kg
C) Adults 70 to 100 kg
D) Adults over 100 kg

Question 15

An LMA may be used ____.

A) in patients who have not fasted
B) in patients with a hiatal hernia
C) as a conduit for emergency resuscitation drugs
D) as an option in emergency situations where an endotracheal tube is not readily available

D) DLT

Question 17

Reported cases of complications associated with the use of the ETC are related to either ____ or air leaks.

A) bronchospasm
B) retching
C) hemodynamic stress
D) laryngeal spasm

Question 18

Recognizing the diameter of the ____ is a crucial determinant of success in the use of a DLT.

A) esophagus
B) chest
C) trachea
D) bronchus

Question 19

The most severe form of airway injuries caused by a(n) ____ is airway rupture.

A) esophageal-tracheal combitube
B) double-lumen endobronchial tube
C) nasopharyngeal airway
D) esophageal gastric tube airway

Question 20

One recommendation for safe placement of a DLT is to remove the bronchial stylet once the tip of the tube is past the ____.

A) front teeth
B) esophageal opening
C) vocal cords
D) laryngeal opening

Question 21

With oropharyngeal airways, some practitioners prefer to insert the airway into the patient's mouth upside down so that the distal end of the airway is facing the ______________.

Question 22

The ideal length of the nasopharyngeal airway should have the distal end of the airway within one centimeter of the _______________.

Question 23

The EOA is a disposable tube; its structure consists of an opening at the proximal (top) end, many small holes near the upper end, and a(n) _______________.

Question 24

With proper sterilization by steam _______________ and careful handling, the reusable LMA can be reused up to 40 times as long as the mask is not damaged.

Question 25

During blind intubation, ventilation through the ETC should be done initially through _______________.

Question 26

Discuss the three methods used to determine the appropriate size of an oropharyngeal airway.

Question 27

Explain why proper sizing of the nasopharyngeal airway is important.

Question 28

List some precautions regarding the use of an EOA.

Question 29

Describe how both lumens on the ETC can be used to provide ventilation.

Question 30

What are the three main uses of DLTs?
