Correct answer: C — Arterial needle infiltration/extravasation – the needle has punctured through the vessel wall
Sudden pain during cannulation with rapid swelling and no blood return indicates needle infiltration (the needle tip has perforated the vessel wall and fluid/blood is extravasating into surrounding tissue). Management: immediately remove the needle, apply firm pressure for 10-15 minutes, apply ice, and elevate the arm. Do not attempt to re-cannulate the same site. If dialysis is urgent, the contralateral arm or a temporary catheter may be needed. Document and report the event. Frequent infiltrations may indicate access problems requiring investigation.
