Chapter 4 Flashcards
Your anesthetic patient, Gretchen, is a 4-year-old, 66 pound (30 kg) female spayed mixed breed
dog, presented for a dental cleaning. She is intubated and receiving inhalation anesthetic and
oxygen through a partial rebreathing system. She is showing the following parameters. She is
unconscious and immobile. Her respirations are regular, shallow and the rate is normal. She
receives an assisted ventilations every 5 minutes. Her heart rate and pulse strength are decreased.
Her mucous membrane color and CRT are normal.
State III, Plane 2 (Surgical / Moderate)
70 beats per minute
pink (mucous membranes)
do not check prepuce (female)
A heartbeat with no subsequent femoral pulse is
indicative of a pulse deficit
Which of the following arteries can pulse be monitored
lingual
carotid
dorsal metatarsal
Which of the following is true for monitoring respirations of an anesthetized patient
A capnometer and capnograph display can be used to monitor the respiratory rate
Reflexes are helpful in determining the anesthetic depth of a patient. This reflex is elicited by lightly touching the medial canthus of the eye. What is the reflex
palpebral reflex
Which of the following are normal for an anesthetized cat
arterial oxygen saturation (SaO2) of 97%
When does the excitatory fighting anesthesia portion of general anesthesia occur
stage 2
When during general anesthesia does endotracheal intubation usually occur
stage 3 plane 1 light
When during general anesthesia does ventromedial eye rotation occur
stage 3 plane 2 surgical moderate
Which of the following parameters are significant indicators that the anesthesia patient has gone from stage 3 plane 3 surgical moderate to stage 3 plane 4 deep
abdominal breathing has started
eyes have changed back to a central position within the globe
CRT is greater than 2 seconds
Which of the following is the best resource to have for monitoring an anesthetic patient
a skilled and conscientious anesthetist
Which of the following monitoring devices gives the most accurate representation of heart rhythm
ECG unit
Sinus arrhythmia in the dog
is related to an increase in HR when inhalation occurs and a decrease in HR when exhalation occurs
The ECG evaluates
the electrical activity of the heart
The P wave of an ECG tracing is indicative of
atrial depolorization
This is defined as ineffective circulation or lack of movement of the heart even with electrical activity
pulseless electrical activity
When monitoring blood pressure via an indirect method it is important to
monitor mean arterial pressure
monitor trends of blood pressure
A pulse oximiter
measures the estimated saturation of hemaglobin with oxygen SpO2
For the anesthetic patient, which of the following is a false statement concerning tidal volum
TV is the volume of water in a tidal wave
When evaluating the end tidal Co2 ETCO2 in relation to the PACO
the end tidal is about 2-5 mmGH less than the PACO
Which of the following is true for blood gas analysis
it is more commonly used in large animal patients
it is an indicator of oxygenation ventilation and acid-base status
sample handling for blood gas analysis is labor intensive
