client rights
a client is entitled to receive service from his/her regular veterinarian unless he/she has been advised that the client/doctor relationship has been terminated, that is assuming that the client is a bona fide one. A client is also entitled to be served or be advised that service is not available at the usual address but a comparable service is available at another practice and that arrangements have been made with that practice. As to quality of service, the client can expect to receive service of the quality that would be provided by any other veterinarian—the 'reasonable man' policy.

Patient discussion about client

Q. I ask a client's Dr. to script flexaril for a lower back spasm and he made it for a drug called zanaflex? I am unfamiliar with zanaflex, what is the difference between it and flexaril 25mg? Benefits? Risks? I got him to order the air mattress and extended bed because client is 6'3" and is already bedridden on my 1st day..try to beat the skin breakdown, already stage I decubitis ulcers. I tried to talk the client into slideboard and lift away arm wheelchair...noway..he wants to walk bent with a rolling walker. He already had a lift chair delivered, so he just goes from bed to lift chair. He refuses to let me bathe him. He can't see, and he has me check his draw up on insulin to make sure it's right. He sends the P.T. man right back out the door after he signs the sheet. Difficult pt.!

A. Flexeril and Zanaflex are different drugs but are both muscle relaxants. There are hardly any differences between the two, clinically wise. If the doctor thought one is better than the other for your client I would suggest you take his advice and use the one he gave you.
