Which prescription abbreviations specifically require the medicine to be delivered by injection?PONPOIVp.r.IMinj.a.c.

IV means intravenous, so the medicine is delivered into a vein; IM means intramuscular, so it is delivered into a muscle. “inj.” is an abbreviation for injection. PO is by mouth, p.r. is rectally, NPO means nothing by mouth, and a.c. means before meals, so those do not specifically indicate injection.
