Final answer:
Before venipuncture, the nurse should verify the order, perform hand hygiene, apply gloves, select a site away from the cellulitis, cleanse the site with antiseptic, check for allergies, and inform the client about the procedure.
Step-by-step explanation:
Before performing venipuncture on a client who will be receiving intravenous (IV) antibiotic therapy for cellulitis, the nurse must verify the physician's order, select the appropriate venipuncture site, and prepare the client and site for the procedure. The nurse should also perform hand hygiene and apply gloves to maintain sterility and prevent infection. It is crucial to identify and avoid the affected area on the lower right arm where the cellulitis is present, to prevent exacerbating the infection. After selecting a suitable site away from the infected area, the nurse should cleanse the site with an antiseptic swab in a circular motion, starting at the center and moving outward, to minimize bacteria on the skin and reduce the risk of introducing pathogens into the bloodstream.
The nurse should also assess the client's history for any allergies, especially to medications or latex, as these could complicate the venipuncture and subsequent treatment. Finally, the nurse should inform the client about what will happen, its purposes, and any potential discomfort to ensure informed consent, alleviate anxiety, and promote cooperation during the venipuncture procedure. Once these steps are completed, the nurse may proceed with inserting the venous catheter and initiating the prescribed IV antibiotic therapy.
