In healthcare, or rather in modern, first world healthcare, when delivering a single drug, it will usually be IM, occasionally sub-cutaneous, and every once in a great while subdermal or intradermal.
If I'm giving a med that has to be delivered by IV, I won't just stick the needle in, push it and take the needle out, even if I don't anticipate pushing any other IV drugs. Basically, if I'm going to go through all the effort of, and cause the scarring by, establishing venous access, I'm going leave it in place just in case it's needed again, either by putting a lock on it (basically just a piece of tubing with a one way valve), or hanging a bag of fluid that's dripping just fast enough to prevent backflow.
Now, I don't do primary care, and in fact, I have very little knowledge of primary care, so it's possible that this isn't true in that setting, though what I do know of primary care says that they very rarely use IV drugs of any description.
