Which instruction should the nurse include when teaching a client about self-administering heparin?

When teaching a client about self-administering heparin, it is important to instruct them to administer the medication into the abdomen. This area is preferred because it has a good amount of subcutaneous fat, allowing for effective absorption of the medication. Injecting into the abdomen provides a consistent absorption rate and minimizes the risk of bleeding or damage to muscle tissue, which can occur if the injection is performed in other areas such as the thigh or upper arm.

In addition, locations within the lower abdomen should be used to maintain a good distance from the umbilicus and any recent surgical sites. This practice helps optimize the medication's efficacy and enhances safety during self-administration.
