In theory, I think it's one of those things where there is a very very low risk of running afowl. But I think it is a very small fraction of less than 1%
Nurses do not aspirate at times because they rarely ever inject anything that shouldn't go IM. Most is basic stuff like vitamins which wouldn't make a difference if it went in IV. Specifically the delts is where some are even trained not to aspirate.
