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

A. The nurse should insert the needle at a 90° angle for subcutaneous injections of enoxaparin, not a 45° angle. B. The air bubble in a prefilled syringe of enoxaparin should not be expelled. This helps ensure the full dose is delivered and avoids injection of air into the tissue. C. The correct injection site is usually at least 5 cm (2 inches) from the umbilicus, but not specifically 2.54 cm. The goal is to inject in the fatty tissue for subcutaneous absorption. D. Aspirating for blood return is not necessary for subcutaneous injections, as it is primarily used for intramuscular injections. The nurse should inject the medication without aspirating.
