A nurse is preparing to administer heparin to a client. Which of the following actions should the nurse plan to take?

A. Inject the medication into the abdomen above the level of the iliac crest: Heparin should be administered subcutaneously, and the preferred injection site is in the abdomen, specifically at least 2 inches away from the umbilicus, usually above the level of the iliac crest. This area has a good amount of subcutaneous tissue and allows for proper absorption of the medication. B. Use a 1-inch needle to inject the medication: For subcutaneous injections, a 1-inch needle may be too long. A shorter needle, typically 5/8 inch, is usually preferred for subcutaneous injections, especially in areas like the abdomen. C. Use a 22-gauge needle to inject the medication: A 22-gauge needle is too large for subcutaneous injections. A smaller gauge needle, typically 25-27 gauge, is used for subcutaneous injections to minimize tissue damage and discomfort. D. Massage the injection site after administration of the medication: Massage should not be done after administering heparin, as it can increase the risk of bruising and hematoma formation at the injection site.
