A nurse is planning care for a client who is scheduled to receive a peripherally inserted central catheter (PICC) in the arm. Which of the following interventions is appropriate for the nurse to include in the plan of care?

Measuring the upper arm circumference is done before and after PICC insertion as a baseline to monitor for complications such as thrombosis or phlebitis — an increase in arm circumference indicates swelling. Chlorhexidine gluconate (not alcohol alone) is used for skin preparation before PICC insertion. PICC flushes use a 10 mL syringe minimum to reduce pressure and prevent catheter damage. Placement is verified via chest x-ray, not MRI.
