2. Coag (light blue/purple)

3. Biochem/lith-hep (orange)

4. Glucose/potassium oxalate (yellow?)

Anaesthesia: ‘anaesthetise a cat for ovariohysterectomy’ - identify the circuit

Ayres T-piece

Anaesthesia: ‘admitted with a suspected ruptured diaphragm’ - identify the circuit

Co-axial Bain

Anaesthesia: ‘anaesthetise a patient for radiography and has requested that a Parallel Lack anaesthetic breathing system’ - identify the circuit

parallel lack

Anaesthesia: ‘wants to anaesthetise a dog for dental treatment.’ - identify the circuit

mini lack

Explain the key steps for an anesthesia task

1. Answer calculation (tidal volume x BW > answer x RR > answer x CF > provide range or answer in ml/min)

2. set up specific circuit and scavenging

3. label oxygen tank and open it, whilst stating amount left in tank

4. perform leak test for minimum of 30s

5. ensure oxygen flow goes up down

6. ensure vaporizer goes left right and announce level of agent

7. ensure APL valve open

8. Alternate task instructions for mini lack (select ET tube, inflate cuff to appropriate level and watch for min 30s, check for damage to cuff/blocked lumen, uncuff tube and set oxygen tank to correct flow rate.)

Explain the key steps for a fluid task 01

1. Answer calculation (kg x 50> ans / time given > ans/60 > leave as full x 20 > round to 2dp. final answer)

2. open admin set and bag from packaging

3. hang bag and close regulator on admit set

4. snap admin tag from admin port and insert pointy tip in bag

5. fill chamber from ½ to ¾ full

6. gently release regulator to fill drip line and shut once fully ran through

7. ensure minimal wastage and sterile technique

8. note: identify bubbles and if any are significant, announce to examiner and run until bubbles are gone, then recheck for any bubbles.

Explain the key steps for a fluid task 2 e.g. check catheter, give drug, record and leave running

1. wear gloves

2. select correct medication, check date of expiry and date of first opening

3. check IV Line is patent and check site for inflammation or infiltration

4. select appropriate syringe and needle, surgical spirit and cotton wool

5. swab top of vial and draw back correct volume of drug required

6. withdraw needle and do not re-sheathe

7. walk to patient, occlude IV, swab injection port and administer medication slowly

8. open drip line to ruin medication through

9. dispose of needle, syringe and gloves

10. leave the drip running at a rate of 1 drop/3 seconds

11. record all information on the hospital sheet
