breed dog in Stage III, Plane 2 (Moderate / Surgical) anesthesia?

A

70 beats per minute

23
Q

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

Arterial oxygen saturation (SaO2) of 97%

24
Q

When during general anesthesia does endotracheal intubation usually occur?

25
Q

The P wave of an ECG tracing is indicative of…

A

atrial depolarization

26
Q

What is the term for ineffective circulation or lack of movement of the heart while still having electrical activity seen on the ECG?

A

Pulseless Electrical activity

27
Q

These Analgesics are effective in reducing inflammation and work well given as pre-anesthetic agents. They inhibit the activity of COX-1 and/or COX-2 enzymes, may decrease platelet function and can harm the production of cartilage. What is this group of drugs?

A

NSAID’s

Q

These Analgesics inhibit the release of norepinephrine and therefore inhibit nerve impulse transmission. They also cause sedation and muscle relaxation. Some of the side effects include hypertension and bradycardia. What is this group of drugs?

A

Alpha-2 agonists

29
Q

Which of the following is/are TRUE to confirm proper endotracheal tube placement in an anesthetic patient?

A

a. Feeling air movement from the distal end of the endotracheal tube.
b. Fogging of the tube (assuming it is a clear tube) from moist exhaled air.
c. Palpating only one firm central structure in the neck (trachea).

30
Q

Povidone Iodine has which of the following characteristics?

A

a. It can be used as a solution for ophthalmic surgery

b. It is deactivated by organic debris.

31
Q

Chlorhexidine Gluconate has which of the following characteristics?

A

It is toxic to the eye and can damage the cornea

32
Q

Which of the following clinical signs, when monitoring an adult medium sized canine anesthetic patient, informs the anesthetist that the patient is at an appropriate surgical level of anesthesia?

A

ventrodorsal rotation of the globe (eye), absent palpebral reflex, 10 breaths/minute, 120 heart beats/minute, very slight jaw tone.

This group of noncontrolled drugs have antiarrhythmic and antihistamine effects but can
cause vasodilation induced hypotension.
