For a subclavian central line, which motion is typically limited?

• A. Shoulder flexion and abduction to 90 degrees
• B. Shoulder adduction to 45 degrees
• C. Shoulder external rotation to 180 degrees
• D. No restriction

Answer: (A)

After a subclavian central line is placed, the catheter runs from the subclavian vein under the clavicle toward the heart. Arm movements that lift the arm away from the body and bring the elbow forward (shoulder flexion and abduction) can place traction on the catheter at its clavicular/first-rib region, risking dislodgement or kinking. To protect the line while healing, movements are commonly limited to about 90 degrees for both flexion and abduction. Adduction to 45 degrees or extreme external rotation aren’t the primary precautions for this line, and having no restriction would increase the risk of catheter movement. Therefore, limiting shoulder flexion and abduction to 90 degrees best preserves catheter integrity and safety.
