A nurse is preparing to administer an antibiotic via intermittent IV bolus for a client who has a continuous IV infusion. Which of the following steps should the nurse take first?

Rationale: The nurse should first check the IV site for signs of infiltration before administering the antibiotic. This is crucial to ensure the client's safety and prevent potential complications such as tissue damage or infection. By assessing the IV site first, the nurse can identify any issues that may affect medication delivery. Hanging the antibiotic bag above the primary infusion, wiping the connection port, or connecting the tubing are all important steps but should only be done after confirming the IV site integrity. Checking the IV site is the priority to prevent harm to the client.
