Ignorance Is Bliss?

I was watching this Asian drama on tv and some of the things I heard on the show made me laugh like hell at it's absurdity. A man had a head injury and was rushed to the hospital. The dr. informs the family members that he has lost a lot of blood (typical tv drama issue) and needs an immediate blood transfusion. Most doctors would be able to catch the fact that you can't have a huge amount of blood collecting in the cranial cavity (skull) due to the lack of space. The second thing the dr. proceeds to mention that the patient's blood group is AB positive and they do not have that blood group in the hospital and cannot accept any other blood type! :P Most high school grads know that AB positive is a universal recipient blood type! You can give them any blood type! And to my shock he goes on to refuse to accept O negative blood type which is the universal donor! People with this blood type can donate to every single blood type! I feel bad for the Asian audience listening to this nonsense. The least they can do is get such basic facts right and educate the poor public.
