Answer 1

State III, Plane 2 (Surgical / Moderate)

Answer 2

indicative of a pulse deficit

Question 3

Which of the following arteries can pulses be monitored?

Answer 3

lingual
carotid
dorsal metatarsal

Question 4

Which of the following is true for monitoring respirations of an anesthetized patient?

Answer 4

A capnometer and capnograph display can be used to monitor the respiratory rate

Question 5

Reflexes are helpful in determining anesthetic depth of a patient. This reflex is elicited by lightly touching the medial canthus of the eye. What is that reflex?

Answer 5

Palpebral reflex

Question 6

Which of the following is / are a normal for an anesthetized cat?

Answer 6

Arterial oxygen saturation (SaO2) of 97%

Question 7

When does the excitatory “fighting anesthesia” portion of general anesthesia occur?

Answer 7

Stage II

Question 8

When during general anesthesia does endotracheal intubation usually occur?

Answer 8

Stage III plane 1 / Light

Question 9

When during general anesthesia does ventromedial eye rotation usually occur?

Answer 9

Stage III plane 2 / Surgical / Moderate

Question 10

Which of the following parameters is a significant indicator that the anesthesia patient has gone from Stage III plane 3 / Surgical / Moderate to Stage III plane 4 / Deep?

Answer 10

abdominal breathing has started
eyes have changed back to a central position within the globe
CRT is greater than 2 seconds.

Question 11

Which of the following is the best resource to have for monitoring an anesthetic patient?

Answer 11

A skilled and conscientious anesthetist

Question 12

Which monitoring devices gives the most accurate representation of heart rhythm?

Answer 12

ECG Unit

Question 13

Sinus Arrhythmia (SA) in the dog…

Answer 13

is related to an increase in HR when inhalation occurs and a decrease in HR when exhalation occurs

Question 14

The ECG evaluates…

Answer 14

the electrical activity of the heart

Question 15

The P wave of an ECG tracing is indicative of…

Answer 15

atrial depolarization

Question 16

This is defined as ineffective circulation or lack of movement of the heart even with electrical activity.

Answer 16

Pulseless Electrical activity

Question 17

When monitoring blood pressure via an indirect method it is important to…

Answer 17

monitor Mean Arterial Pressure

monitor trends of Blood Pressure

Question 18

A Pulse Oximeter…

Answer 18

measures the estimated saturation of hemoglobin with Oxygen (SpO2)

Question 19

For the anesthetic patient, which of the following is true concerning TIDAL VOLUME (TV)?

Answer 19

• TV is calculated at 10 to 15 ml / kg
• TV is the amount of air that passes in or out of the lungs in a single breath.
• TV multiplied by the respiratory rate is the Minute Volume.

Question 20

When evaluating the End-Tidal CO2 (ETco2) in relation to the Paco2…

Answer 20

the End-Tidal CO2 (ETco2) is about 2-5 mmHg less than the Paco2

Question 21

Which of the following is / are true for blood gas analysis

Answer 21

• It is more commonly used in large animal patients.
• It is and indicator of oxygenation, ventilation and acid-base status.
• Sample handling for blood gas analysis is labor-intensive.
