An unlicensed assistive personnel (UAP) is assisting with the care of a client with a peripherally inserted central venous catheter (PICC). Which guidance should the practical nurse (PN) provide to the UAP?

A. Keeping the head of the bed elevated is not specifically related to the care of a PICC line. The elevation may be a general comfort measure but is not a specific instruction for PICC line management. B. Changing the dressing over the PICC line insertion site is a sterile procedure that should be performed by a licensed nurse, not a UAP. This task requires specific training and adherence to infection control practices. C. Feeding the client all meals to reduce arm movement is not necessary and may be overly restrictive. The UAP’s role does not include limiting the client's activity beyond reasonable measures. D. Using the opposite arm for blood pressure measurement is the correct guidance. It prevents potential interference with the PICC line and helps avoid complications such as dislodgement or infection.
