The American rules for the use of the articles "a," "an" and "the" and British English is somewhat different and allows the following "The man went to hospital to see nurse." American English would require the following "The man went to a/the hospital to see a/the nurse." The choice of "a" and "the" would depend on whether he wanted to see a particular nurse at a particular hospital or any nurse at any hospital.
