how would you differentiate V+ from regurg?
how soon is it after eating? (regurgitation occurs soon after eating while V+ is more variable)
is there any hypersalivation or attempts to swallow? this is consistent with V+
is there any active retching or abdominal effort? this is present with V+ only
what does it look like? if undigested food is present regurgitation is more likely
list gastrointestinal causes for V+ in cats
inflammatorybowel disease
lymphoma
parasitic bacterial or viral disease
food responsive enteropathy
list extra-GIT causes of V+ in cats
hyperthyroidism
pancreatitis
hepatobiliary disease
renal disease
vestibular disease
medication reactions

determining if anaemia is hyper, normo and hypochromic depends on what value?
MCHC
determining the cell size in anaemia is dependent on what?
MCV
what type of anaemia does this dog have?

how to perform the coombs test?
collect blood into an EDTA tube
spin to remove plasma
expose the washed RBCs to coombs reagent
microscopic examination is performed to see if agglutination has occurred
if they have clumped together this is a positive test which indicates the presence of IMHA

DEA 1.1negative and DEA 1.1positive
which canine blood type is the universal donr?
DEA 1.1 negative
what are the causes of pink/red urine?
haematuria e.g., bleeding disorders, bladder stones and UTI
iatrogenic blood from sampling (cystocentesis only)
haemoglobinuria e.g., IMHA and toxins
myoglobinuria e.g., muscle damage
what four biochemistry markers increase with HAC?
phosphate, cholesterol, ALP and ALT
Cytological examination of fluid obtained by thoracocentesis from a dog with dyspnoea showed the following: A cellular effusion containing a mixture of non-degenerate neutrophils and small lymphocytes with scattered occasional red blood cells. What is the underlying cause likely to be?
chylothorax
You are presented with an 8 ]yo MN springer spaniel, the owner reports that the dog has been sneezing and rubbing the right side of its face on the carpet for the last 10 days. This has been getting progressively worse and recently the dog has developed a unilateral right-sided purulent nasal discharge. Your colleague prescribed a course of broad spectrum antibiotics which resulted in a decrease in the severity of the discharge which has worsened again since the antibiotic course was completed. Which condition affecting the canine nasal cavity is the most likely diagnosis?
nasal foreign body
A 10-year old female neutered springer spaniel presents to you with a 6 month history of coughing, the cough is dry and non-productive and is not getting any better or worse. The dog is otherwise well, plain lateral and dorso-ventral thoracic radiographs are largely unremarkable, a bronchoalveolar lavage sample reveals 76% non-degenerate neutrophils, no infectious organisms are seen or cultured. What is the most likely diagnosis?
chronic bronchitis
You evaluate a kitten that you suspect has cat flu. The kitten has ocular discharge, corneal ulceration, sneezing, pyrexia and inappetence. Which feline virus is most likely to account for these signs?
herpes

This electrocardiogram was taken from a 7 year old Labrador who the owner reports has been suffering from sudden onset exercise intolerance.
