What should a nurse measure daily on a patient who has a PICC line?

Measuring the arm circumference above the insertion site of a PICC (Peripherally Inserted Central Catheter) line is essential for monitoring potential complications such as thrombosis, hematoma, or infection. Changes in arm circumference can indicate swelling caused by issues related to the line itself, which can lead to further complications if not addressed promptly. By assessing the arm circumference daily, the nurse can detect any early signs of complications, allowing for timely intervention to maintain patient safety and prevent further issues.

Monitoring the other options, while important in general patient care, does not specifically relate to the management of a PICC line. Temperature can indicate infection but is not specific to the line itself. Blood pressure is a routine vital sign measurement, and the length of the PICC line is usually established upon insertion and does not require daily measurement unless there are specific concerns.
