Why is it important to avoid tension on a PICC line during PT?

• A. To prevent cosmetic issues.
• B. To prevent line dislodgement and thrombosis.
• C. To increase infusion rate.
• D. To improve patient comfort only.

Answer: (B)

Tension on a PICC line can pull the catheter out of the vein or cause it to kink, which risks dislodgement and compromised central venous access. When the line is pulled, the tip can migrate from its ideal position in the lower part of the superior vena cava, leading to infusion leaks, ineffective therapy, or even air embolism. At the same time, traction irritates the vessel and surrounding tissues, increasing the chance of clot formation around the catheter (thrombosis). In physical therapy, arm movement or positioning can create this traction, so keeping the line tension-free and well-secured minimizes these serious complications and allows safe, effective therapy. Cosmetic concerns, changes in infusion rate, or comfort alone don’t address these critical risks.
