1

Trace the flow of O2 through the system to the patient.

E tank -> pressure reducing valve -> flow meter -> vaporizer -> unidirectional valves -> patient -> unidirectional valves ->manometer -> soda lime -> reservoir bag -> scavenger

2

How do you know when to change the scavenge system?

after each use you weigh it and once it has gained 50 grams of its initial weight you replace it

3

What are areas on the patient's body that should be observed to gain information about the patient's behavior?

the chest, thorax, eyes, the mouth, the heart, temperature, the femoral artery or dorsal pedal for pulse

4

Why is it important to keep the power control set to a lower setting?

so it doesn't heat up and cause damage to the teeth

5

Used to detect softened areas and defects in enamel.

explorers

6

How deep can periodontal probes measure?

up to 6 sites around a tooth's circumference

7

This instrument is used to assess periodontal disease.

periodontal probes

8

Periodontal explorer that has a sharp, thin tip curved into a _______

Shepard's hook "crook"

9

This instrument is used to remove heavy calculus from the surface of the tooth

Calculus removal forceps

10

This instrument removes calculus and plaque from the surface of the crown of the tooth

scalers

11

What area are scalers used?

supragingival use only

12

Why are scalers limited to that area?

because of the potential for gum damage

13

What is the recommended care of curettes and scalers?

they must be sharpened after every use with an oiled flat stone at a 110 degree angle

14

What instrument is used to remove subgingival deposits form the root surface and debride tissue lining

curettes

15

Why are pulse oximeters readings inaccurate in the presence of carbonoxyhemoglobin and methemoglobin?

because it only measures the percentage of hemoglobin with oxygen

16

What other patient situations cause a reduced pulse oximeter signal?

anemia and vasoconstriction

17

Why would a capnograph be inaccurate in hypoventilation but useful when controlling ventilation?

because it measures the end tidal volume of CO2

18

When is complete sterilization of items obtained?

most items is achieved after 9-15 minutes(doesn't matter) of exposure to 250 degrees F minimum of 15 psi

19

What are the 2 main types of autoclaves and the difference between them?

1) gravity displacement autoclaves-the steam gradually displaces the air contained within a chamber and forced out through a vent
2) prevacuum autoclaves-is larger and is equipped with a boiler to generate steam and a vacuum system

19

How is exposure time related to internal pressure and steam temperature?

Heat is the killing agent and steam is the vector that supplies the heat and promotes penetration of the heat. Pressure is the means to create adequately heated steam.

19

What are the PPE use when performing a dental prophy?

gloves, mask, an eye shield

20

List the veins and animals that are used for IV catherterization.

dog: cephalic, lateral saphenous, jugular
cat: cephalic, femoral, jugular

21

List the two main different types of fluids and then give an example for the use of each type.

1) crystalloids- lactated ringer's solution/0.9% NaCl, can pass through a semipermeable membrane and eneter all body compartemnts
2) artificial colloids-hetastarch/tetrastarch, are used in conditions which the vascular space cannot retain an adequate fluid volume

22

List the veins and animals that are used for venipuncture

dog: cephalic, jugular
cat: femoral, jugular

23

List the two main different types of fluids and then give an example for the use of each type.

1) crystalloids- lactated ringer's solution/0.9% NaCl, can pass through a semipermeable membrane and eneter all body compartemnts
2) artificial colloids-hetastarch/tetrastarch, are used in conditions which the vascular space cannot retain an adequate fluid volume

24

Why should the leg be cleaned of any blood that is outside the catheter?

blood is a good culture medium for bacterial growth so removing that will help decrease the possibility of infection

25

How often should the fluid administration set be changed if continuous IV fluid administration is maintained?

change fluid administration set every 24 to 72 hours

26

How often should the catheter be flushed with heparinized saline if not on continuous fluid administration?

every 8 to 12 hours

27

What is the most common support bandage placed on the patients?

Robert-Jones, vetwrap, elasticon

28

What is the major complication associated with intraosseous catheters?

1) sepsis
2) osteomyelitis
3) contraindicated in fractured bones
