What should medical assistant do when performing a veinputure on an adult patient for blood cultures?

When performing a venipuncture on an adult patient for blood cultures, the medical assistant should first verify the patient's identity and explain the procedure to alleviate any anxiety. They should then prepare the site by cleaning it thoroughly with an appropriate antiseptic solution, typically iodine or alcohol, and allow it to dry completely. After securing the patient's arm, they should use a proper technique to insert the needle into the vein, collect the blood in sterile culture bottles, and ensure the site is bandaged after the procedure. Finally, they should label the specimens accurately and document the procedure.
