Quiz on Anesthesia and Analgesia of Dogs, Cats, and Ferrets

These questions were kindly donated by Dr. Victoria Hampshire, to whom I am very grateful. She sent a CD of material used by USUHS students to prepare for the board exams in 2000, including outlines of the entire blue book on anesthesia complete with questions.
