Which of the following actions is recommended after drawing blood from a client?

Asking the client to hold pressure on the venipuncture site after drawing blood is a crucial step in the procedure. This action helps prevent hematoma formation and minimizes bleeding at the site. Applying adequate pressure for a sufficient duration promotes clotting of the punctured vessel, which is vital for reducing the risk of complications.

This practice is grounded in the understanding of vascular biology and hemostasis, as maintaining pressure facilitates the natural processes that lead to closure of the punctured vein. It is also significant in promoting patient comfort and safety following the procedure.

Other options present alternatives that do not align with best practices; for example, immediately applying a bandage without ensuring that bleeding has stopped could result in blood escaping from the site under the bandage, potentially leading to complications. Leaving the needle in place for 10 seconds is unnecessary and could create additional discomfort for the patient, while disposing of the needle in a regular waste bin poses significant safety risks and goes against proper sharps disposal protocols.
