A nurse is giving iron dextran intramuscularly (IM). Which rationale correctly states why the nurse should implement the Z-track method?

A. Makes the injection less painful: While it may help slightly, the primary reason is not pain management. B. Prevents staining of the skin: Iron dextran is a dark, stain-like medication. The Z-track technique (displacing the skin before injection) creates a zigzag path that seals the medication in the muscle and prevents it from leaking into the subcutaneous tissue and staining the skin. C. Allows another injection at the same location: Site rotation is always required; Z-track does not change this. D. Prevents postinjection pain: Post-injection soreness is common regardless of the technique used for iron.
