Nurse, check his blood pressure and then prepare an IV.

Does an IV refer to an intravenous injection? If not, what is it? Thanks.

Yes, IV is for intravenous, but used as a noun. See this:

In more recent years, the word "intravenous" has taken on a second role: as a noun. Thus, "an intravenous" refers to an intravenous fluid drip, a solution (usually a balanced electrolyte solution) administered directly into the venous circulation. Also called a drip. -- http://www.medterms.com/script/main/art.asp?articlekey=4064
