Q

Which of the following is NOT an ophthalmic surgery instrument

Groove Director

17
Q

This absorbable monofilament suture material has good relative knot security, mild tissue reactivity, maintains up to 69% tensile strength at 42 days post-surgery and is completely absorbed in 180 days.

A

PDS

18
Q

What is the purpose of the “Murphy Eye” of an Endotracheal Tube?

A

It helps prevent asphyxiation in the event that the beveled end opening in the trachea is blocked with mucous or other substance.

19
Q

What is NOT a true statement of a supraglottic airway device (SAD)?

A

It has a blade and light source which allows for depressing the tongue and better visualization of the throat.

20
Q

Which of the following are true for the use of anesthetic masks and chambers?

A
  • Neither maintain an open airway.
  • Neither protects against pulmonary aspiration
  • Neither allow for manual ventilation of the patient.
21
Q

A

E oxygen tank

22
Q

This anesthesia machine structure delivers pure oxygen at a rate of 35 to 75 Liters per minute when used. What is this structure?

A

oxygen flush valve

23
Q

Immediately after administering a manual ventilation (with a partial-rebreathing (semi closed) system the anesthetist…

A

opens the “pop-off” valve

24
Q

The Carbon Dioxide absorber granules…

A

are exhausted when the color of the granules are tan

25
Q

Which of the following is an example of a non-rebreathing anesthetic system?

A

Modified Mapleson A system
Bain Coaxial System
Ayre’s T piece system

26
Q

How frequently should a test for low – pressure leaks on an anesthetic system be performed?

A

Before each use

27
Q

After injectable anesthetic induction, continued gas anesthetic induction is usually necessary to have the patient achieve maintenance anesthesia. Which of the following
anesthetic gas induction protocols is best for a 30 kg patient on a partial rebreathing system (semi-closed)?

A

Isoflurane at 3% and Oxygen Flow rate at 3 Liters per minute

28
Q

Active Scavenging…

A

is a mechanical device using a vacuum to remove gases

Best at conserving heat and moisture

29
Q

Passive Scavenging

A

works best if restricted to a room vent on an outside wall.

30
Q

Activated Charcoal Canister

A

Should be suspended above the floor so air can circulate through the vents.

31
Q

Total Rebreathing (Closed)

A

Best at conserving heat and moisture

32
Q

Partial Rebreathing (Semi-Closed)

A

The usual Oxygen flow rate for maintenance anesthesia is calculated at
20 – 40 ml / kg / min.

33
Q

Non-Rebreathing (Semi-Open/Open)

A

Generally recommended for patients weighing less than 7 kg

Does not usually contain a CO2 absorber canister, pressure manometer and unidirectional valves.

34
Q

What is this part of the anesthesia machine that is calibrated in liters per minute or milliliters per minute?

A

Oxygen Flow Meter

35
Q

What is this part of the anesthesia machine that is calibrated in percentage of total anesthetic gas exiting?

A

Out of Circuit (Circle) Precision Vaporizer

36
Q

What is this part of the anesthesia machine that indicates the pressure of the gases within the breathing circuit (circle). This pressure is also represented by the pressure in the patient airways and lungs.

A

Pressure Manometer
