Why might a student not receive insulin from their pump?

The reason a student might not receive insulin from their pump is due to a dislodged infusion set. The infusion set enables the insulin pump to deliver insulin under the skin directly into the bloodstream. If the set becomes dislodged — meaning it is no longer properly secured or has been pulled out — insulin cannot be delivered effectively. This situation could lead to elevated blood glucose levels because the body's insulin requirements would not be met.

In contrast, high glucose levels may occur as a consequence of not receiving insulin, but they do not directly prevent the delivery of insulin from the pump. Low physical activity does not impede insulin delivery from the pump either; rather, it may affect insulin sensitivity and glucose metabolism. Excessive fluid intake is unrelated to insulin delivery from the pump; while it can influence blood glucose levels and hydration status, it does not affect whether insulin is administered from the pump. Thus, the primary concern regarding the delivery of insulin hinges on the integrity and proper placement of the infusion set.
