VM 580 EXAM STUDY QUESTIONS AND
100% CORECT ANSWERS!!
Which receptors do opioid drugs act on?
Mu, delta, or kappa receptors
How do alpha-2-adrenergic agonists affect urine output in dogs and cattle?
Increase urine production by inhibiting ADH and increasing renal collecting duct permeability in
a dose dependent fashion.
A non-rebreathing system requires a higher or lower oxygen flow rate as compared to a
rebreathing system?
Higher
True/False - Ketamine has analgesic properties.
True
What type of drug is Alfaxalone?
A non-barbiturate sedative that is a neuroactive steroid.
What component of rebreathing circuits is missing when a non-rebreathing system is used?
Soda lime
An anesthesia machine with a circle breathing system has 3 pressure zones. What are the
correct pressure zones, starting from the tank to the circuit?
2,000 PSI / 50 PSI / 15 PSIA
What drug provides sedation/tranquilization without analgesia?
Acepromazine
You are presented with a 12 yo Black Lab for a dental cleaning, no medical issues. BCS 7/9,
PCV 45%, TP 6.5 g/dL, normal Chem. You auscult a heart murmur, left basilar, systolic,
,Grade 3/6, and surmise it is secondary to mitral regurgitation. What ASA status would you
assign this dog?
2
What drug is not recommended for use in a dog that will be going to surgery for a
splenectomy?
Acepromazine
Which chemical property of modern inhalant agents dictates that they be delivered
through calibrated, agent-specific, out of circle vaporizers?
Vapor pressure
True/ False - The less soluble an inhalant anesthetic is in blood, the faster it will be
eliminated from the body.
True
What is the most obvious clinical sign associated with a tracheal tear?
Subcutaneous emphysema
What is the cardiogenic effect associated with the administration of dexmedetomidine for a
dog?
Bradycardia
Which of the following inhalant anesthetics is the least potent? Iso-, Sevo-, En-, Des-
flurane, or Halothane.
Deslurane
Endotracheal tube sizes reference the
Internal diameter in mm
Inhalation agents decrease blood pressure by:
Causing myocardial depression and decreases in systemic vascular resistance.
, Regarding flow of fluid through an IV catheter, what happens when you double the length
of the catheter?
It halves the flow rate
Anesthesia induction plan is IV propofol, canine weight is 20 kg, propofol concentration is
1%, the plan is to draw 6 mg/kg into syringe for injection. How many mL of propofol will
you draw into the syringe?
12.0
What type of sterilization occurs through denaturing cellular proteins as a function of time
and temperature?
Steam sterilization
What type of sterilizations occurs when reactive oxygen species interfere with metabolism
and reproduction?
Hydrogen peroxide gas plasma
What type of sterilization occurs through alkylation (by blocking metabolic reactions)?
Ethylene oxide sterilization
What is the mechanism of action of Chlorhexidine scrub?
Alters cell wall permeability and precipitates intracellular contents.
What is the mechanism of action of Alcohols (isopropyl and ethyl)?
Denatures proteins and inhibits metabolites for cell division.
What is the mechanism of action of Iodophors (povidone iodine)?
Penetrates cell wall and inhibits protein synthesis by forming protein complexes.
What is the mechanism of action of Quaternary ammonium compounds?
Impairs bacterial permeability by binding irreversibly to phospholipids and proteins in the cell
membrane.
