A nurse is caring for a client who is receiving total parenteral nutrition via a peripherally inserted central catheter (PICC). When assessing the client, the nurse notes swelling of the client's arm above the PICC insertion site. Which of the following actions should the nurse take first?

Rationale:A. Removing the PICC line should only be done if directed by a provider after further assessment.B. The first action is to measure the circumference of both arms to assess for possible complications such as thrombosis or infiltration. This measurement will help determine the extent of the swelling and inform subsequent actions.C. Notifying the provider is important but should be done after gathering relevant assessment data, such as the arm circumference.D. Applying a cold pack may be appropriate for reducing swelling but is not the first step. Assessment should come first.
