I agree with the fact that we as vet students actually learn a lot from the nurses. In HK, all the vet nurses you find in clinics (all practises in HK are private clinics) are not qualified and are trained on the job, and they act as translaters because most vets are foreigners and most of our clients can't speak English. But if the nurses have been trained in good practises, they can be very knowledgable in terms of husbandry, restraint, surgury assistance, hospital care, drugs etc. They probably don't understand the pharmacology behind the drugs or anatomical stuff in detail, but they know which drugs are likely to be used in what cases and the surgical preparations and suture materials required at different times.
When I see practice I basically work as a vet nurse and I have huge respect for the nurses I work with because they are really well-trained, esp. when dealing with annoying clients............
