Correct answer: A — Pump site failure or disconnection leading to insulin interruption

Pump-related DKA most commonly results from insulin delivery interruption due to infusion set problems (kinking, dislodgement, occlusion) or prolonged disconnection. Because pumps deliver only rapid-acting insulin, interruption leads to rapid ketosis (within 4-6 hours). Patients must be educated to check for ketones if BGL >15 mmol/L and to revert to injection therapy if pump issues cannot be resolved.
