A. Oropharyngeal airway
B. Vasocontricting local anesthetic
C. Nasopharyngeal airway
D. Vasodilating local anesthetic

A

B. Vasocontricting local anesthetic
C. Nasopharyngeal airway

18
Q

A. CXR
B. ETCO2
C. Fiberoptic examination
D. Oxygen concentration

A

C. Fiberoptic examination

19
Q

Which of the following statements are true regarding the Oral Airway? (Select 2).

A. It increases the work of respiration when used in conjunction with a face mask.

B. It is sized by measuring the mouth to the earlobe.

C. It decreases the work of respiration when used in conjunction with a face mask.

D. It lifts the tongue and epiglottis away from the posterior pharynx.

A

C. It decreases the work of respiration when used in conjunction with a face mask.

D. It lifts the tongue and epiglottis away from the posterior pharynx.

20
Q

The slanted bevel of an endotracheal tube provides:

A. A view of the larynx
B. A safeguard against esophageal intubation
C. an ETCO2 reading
D. An alternative pathway for gas flow

A

A. A view of the larynx

21
Q

After gas passes through tubing, the pressure at the outlet as compared to the inlet is:
a. lower
b. higher
c. equal
d. indeterminate

A

a. lower

When gas passes through a tube, the pressure at the outlet will be lower than at the inlet

22
Q

The fresh gas flow is 2 L/min and the patient’s tidal volume is 5 L/min, emergence after turning off the sevoflurane would be:
a. slower.
b.would not occur.
c. unchanged as these factors do not effect emergence.
d. faster.

A

slower

During induction, when alveolar tensions are lower than those in the fresh gas flow, rebreathed alveolar gas will reduce the inspired tension and prolong induction.

During emergence, if the alveolar partial pressure exceeds that of the inspired gases, and rebreathing slows agent elimination.

23
Q

When flow exceeds a critical rate, flow becomes:

a. turbulent.
b. deleterious.
c. laminar.
d. irreversible.

A

a. turbulent.

Turbulent flow
Flow lines are not parallel
”Eddies”: composed of particles moving across or opposite the general direction of flow
Flow rate is same across the diameter of the tube
Generalized - When the flow of gas through a tube exceeds the critical flow rate
Localized - Gas flow rate below the critical flow rate but encounters constrictions, curves, or valve

24
Q

Modification of which Mapleson system has the addition of coaxial tubing?

a. Mapleson A
b.Jackson-Rees
c.Mapleson E
d. Mapleson D

A

mapleson D

Mapleson D has a modification with the addition of coaxial tubing and is called a Bain System
