The capillary refill time (CRT) of an anesthetized 11-year-old Ragdoll cat is 4 seconds.
Besides reduced arterial blood pressure, what would be the most likely additional cause
of the prolonged CRT - Answer- Poor tissue perfusion (can be caused by low art blood
pressure or peripheral vasoconstriction)
A patient exhibits fever and dark-red mucous membranes. What does this most likely
indicate - Answer- sepsis
Which drugs commonly given during surgery is most likely to cause prolonged capillary
refill time (CRT) - Answer- Alpha-2's (they cause significant peripheral vasoconstriction,
thus slowing CRT - this can be transient)
The veterinarian should be notified immediately if the mean arterial pressure (MAP) of
an anesthetized animal reaches what threshold - Answer- 60 mm Hg (leads to poor
kidney perfusion)
During surgery on a 9-month-old male Beagle dog, the technician notices pale mucous
membranes in the animal. Poor tissue perfusion and shock are ruled out. The
veterinarian asks the circulating nurse to check the patient's medical record to see if
what was done before surgery - Answer- A CBC or PCV to identify anemia
The technician determines that the blood vessels of a mixed-breed dog under
anesthesia are expanding, and blood is pooling. Venous return to the cardiac system is
decreased, thus reducing the animal's blood pressure. What would be the most likely
cause of the dog's hypotension - Answer- Excessive vasodilation
A patient who has had cardiac arrest begins to spasmodically contract its diaphragm
after a long period of apnea; this is detected as rapid movement in the patient's
diaphragm, jaw, or larynx. What should the technician do - Answer- Agonal breathing -
the veterinarian must be notified immediately
The respiratory rate of an anesthetized 3-year-old cat is 5 breaths/min. This is most
likely a sign of which of what - Answer- Excessive anesthetic depth leading to
hypoventilation
A technician needs to assess muscle tone while monitoring anesthesia during a dental
procedure, but the jaw, of course, is not available. Which muscle is the best substitute
for assessing jaw tone - Answer- anus
, Which drugs are the most likely to interfere with the pupillary light response, rendering
the reflex an unreliable gauge of anesthesia - Answer- anticholinergics
Which patient's position will place the greatest pressure on the abdominal organs and
diaphragm, thus inhibiting normal respiratory function - Answer- Dorsal recumbency w/
neck fully or hyperextended
During surgery, a technician is using a pulse oximeter to monitor a patient. In addition to
monitoring the pulse rate, what other additional tasks does the machine do - Answer-
Evaluates oxygen saturation and tissue perfusion
Which component of a pulse oximeter determines oxygen saturation - Answer- Infrared
light
What is the normal range of arterial oxygen saturation in an anesthetized dog or cat -
Answer- 95-99%
What is the normal mean arterial pressure in an awake dog or cat - Answer- 85-120 mm
Hg
43. What is the normal mean arterial pressure in an anesthetized dog or cat - Answer-
70-99 mm Hg
44. What is the normal ETCO2 in an anesthetized dog or cat - Answer- 35-45 mm Hg
45. Which machines are the most helpful when the technician wants to evaluate an
anesthetized patient's respiratory rate and the quality of its respirations - Answer-
capnograph
46. The plateau on the display wave of a capnography tracing is most likely to indicate
what in an anesthetized patient - Answer- End tidal CO2 value
47. When administering a ventilating breath, close the pressure relief valve and
squeeze the reservoir bag, making sure that the manometer does not exceed what
value - Answer- 20 cm H2O
48. During surgery, an anesthetized 4-year-old mixed-breed dog has an expired CO2
level of 25 mm Hg. The capnometer is checked and is in good working order. What
would most likely correct the hypocarbia - Answer- Increase anesthetic depth, ease up
on manual ventilation, administer analgesics, or treating underlying hypoxia
49. During surgery, an anesthetized 4-year-old mixed-breed dog has an expired CO2
level of 55 mm Hg. The capnometer is checked and is in good working order. What
would most likely correct the hypercarbia - Answer- Increasing ventilation to drive off
excess CO2
