Which pump-related issue can manifest as signs of impending pump failure?

• A. High blood pressure
• B. Hair loss
• C. Infusion set dislodgement
• D. Blue urine

Answer: (C)

When a pump isn’t delivering insulin properly, the most immediate and telling sign is disruption at the infusion site. If the infusion set becomes dislodged, insulin stops entering the body or does so inconsistently. That interruption leads to rising blood glucose and potential ketosis if not addressed, and it might show up as an alarm or as persistent hyperglycemia even though the pump is functioning. This directly reflects a delivery problem, making it the best indicator of impending pump trouble. High blood pressure, hair loss, and blue urine aren’t connected to the mechanics of insulin delivery from a pump. They don’t signal an issue with the pump’s ability to deliver insulin, whereas an infusion set that’s not properly in place clearly points to a failure in the delivery pathway that needs correction.
