What is the role of a nurse in monitoring IV therapy?

The role of a nurse in monitoring IV therapy primarily involves assessing the insertion site and monitoring for complications. This is crucial because IV therapy can present various risks, such as infiltration, phlebitis, or infection, which can lead to serious patient complications if not identified and addressed promptly.

By regularly assessing the insertion site, the nurse can check for signs of complications, such as redness, swelling, or pain, indicating potential issues that may require intervention. Constant vigilance allows the nurse to ensure the safety and effectiveness of the IV therapy and to provide appropriate care and communication with the healthcare team if problems arise.

The other choices highlight actions that do not represent the complete or appropriate scope of a nurse's responsibilities in the context of IV therapy. For example, administering medications without oversight undermines the collaborative and safe approach required in patient care. Changing medication orders frequently could also lead to confusion and errors in medication administration, and only monitoring patient vitals lacks the comprehensive assessment needed to manage IV therapy effectively. Therefore, thorough monitoring of the insertion site and being alert for possible complications is essential for ensuring patient safety during IV therapy.
