Regarding subcutaneous injections, when is aspiration recommended?

• A. Always aspirate for all subcutaneous injections.
• B. Aspirate only for injections such as heparin.
• C. Never aspirate for subcutaneous injections.
• D. Aspirate for all injections except for insulin.

Answer: (B)

A subcutaneous injection is typically deposited into fatty tissue, where the chance of hitting a blood vessel is low. Aspiration is used only when there is a real risk that injecting into a vessel could cause harm, so you check for blood return before delivering the dose. Heparin is a classic example: if the needle tip were in a blood vessel, it could lead to rapid systemic effects or bleeding. By aspirating, you can detect any blood return and re-site the injection if necessary, reducing the chance of inadvertent intravascular administration. For many other subcutaneous meds, routine aspiration isn’t required because the risk of injecting into a vessel is minimal and the practice could cause unnecessary tissue trauma. So the best guideline reflected here is to aspirate for drugs like heparin, but not as a universal rule for all subcutaneous injections. If you do aspirate and see blood, discard that site and choose a new one before proceeding.
