What is an appropriate technique for administering a subcutaneous heparin injection?

• A. Use 90-degree angle with a small pinch of skin; avoid massaging the injection site; rotate sites.
• B. Use 15-degree angle with no pinch; massage after injection; keep same site.
• C. Use 90-degree angle with no pinch; massage after.
• D. Use 45-degree angle with a large pinch; rotate once per week.

Answer: (A)

Using a 90-degree angle with a small pinch of skin places the needle into subcutaneous tissue rather than muscle, which is essential for subcutaneous heparin injections. The 90-degree approach, combined with a gentle pinch, helps ensure the medication is deposited where it’s intended and reduces the risk of injecting into muscle, which could alter absorption and increase pain or injury. Rotating injection sites is important to prevent lipodystrophy and scar tissue from forming at repeated sites, which can affect how consistently the drug is absorbed over time. It also helps maintain skin integrity and comfort. Avoid massaging the injection site after giving heparin because it’s an anticoagulant; rubbing or massaging can increase bleeding risk, promote hematoma formation, and lead to unpredictable absorption. In practice, the abdomen is a common site for subcutaneous heparin, with injections made at safe distances from the umbilicus and sites rotated to maintain tissue health. Techniques that use different angles, no pinch, massaging after the injection, or repeating the same site without rotation are less safe and do not align with standard subcutaneous heparin administration.
