Lab 1

Question Answer
What does % solution mean?g/100ml
How many mg/mL in a 2.5% solution?25 mg/mL
How many mg/nL is in a 5% solution?50 mg/mL
How many mL water should be added to 1g of Thiopental to make a 2.5% solution?40 mL
What is the induction volume of Thiopental (2.5% solution) dose 10 mg/kg to a 15kg dog?6 mL
You want to induce a 600kg horse with ketamine 10% (2mg/kg) & diazepam 0.5% (0.02mg/kg). How much of each should you give?12 mL Ketamine, 2.4 mL Diazepam
Which drug has anti-arrhythmic properties?Acepromazine

Lab 2

Question Answer
How many liters are in an E tank?600L
How many liters are in an H tank?6000L
How does the pressure regulator change the O2 pressure?2200 to 55 psi
How does the flow meter knob change the O2 pressure?55 to 14.7 psi
What does the vaporizer dial determine?concentration of anesthesia that leaves the vaporizer
What should you make sure to do before pushing the O2 flush valve?Unhook the patient!
What is the route of O2 from tank to breathing system?O2 tank→ pressure gauge + regulator→ flowmeter→ vaporizer→ common gas outlet → breathing system
When should the leak test be performed?Before every procedure
Leak test method...?close patient end→ close pop-off valve → turn on O2→ get P at 30cmH20 for 10 sec→ open pop-off valve→ empty bag→ uncover patient end
When should a non-rebreathing system be used?Animals under 7 kg
Which breathing system uses soda-lime?Re-breathing
How do you calculate minute volume?RR x TV
What is the tidal volume?10-15 ml/kg per breath
FGF on a non-rebreathing system?(TV*BW)*RR*System factor
Length of a ET Tube?Tube should be from incisors to thoracic inlet
What needs to be checked before inserting the tube?Check the cuff to make sure there isn't a leak
How do you make sure the cuff is inflated enough?close pop-off valve → inflate bag to 20cm/H2O for 10sec → squeeze bag to 30cm/H2O for 10 sec (check before inflating to see if you need to inflate at all)

Lab 3

Question Answer
Proper steps to set up?Capnograph, Pulse-ox, Oscillometric BP Cuff, ECG, Doppler, Temperature probe, Esophageal Stethoscope
What is a normal pulse-ox reading?>96%
If the baseline of a capnograph is rising what is suspected?Rebreathing CO2
If the capnograph looks like a shark fin what do you suspect?Airway obstruction
If the capnograph looks like camel humps what do you suspect?Tachypnea
If the capnograph has fluctuation on the inspiration segment what do you suspect?Artefact from cardiac oscillation
If the capnograph gets taller but the baseline doesn't change what do you suspect?Hypoventilation
If the capnograph gets shorter but the baseline doesn't change what do you suspect?Hyperventilation
If the capnograph looks is flat what do you suspect? Either the machine needs checking or the patient is dead
On an ECG there is variable space between each QRS wave. What do you suspect?Sinus arrhythmia
On an ECG there is increased P-R interval. What do you suspect?AV block (1)
On an ECG there are P waves not followed by QRS waves. What do you suspect?AV Block (2)
On an ECG the T waves are notably tall and reduced to absent P waves. What do you suspect?Hyperkalemia
