Rationale: An air lock and a Z-track technique should both be used when administering iron by the intramuscular route. Proper technique includes changing the needle after drawing up the medication but before giving it to prevent staining of skin. The dorsogluteal site should be used only after proper identification of appropriate landmarks. After the needle is inserted, the nurse should aspirate for the presence of blood and should proceed with the administration if no blood is aspirated. The site should not be massaged after injection because massaging could cause staining of the skin.
