Practice
A patient with type 1 diabetes who is receiving a continuous subcutaneous insulin infusion via an insulin pump contacts the clinic to report mechanical failure of the infusion pump. The nurse instructs the patient to begin monitoring for signs of:
Correct answer
B
Rationale
The correct answer is B: diabetic ketoacidosis. When an insulin pump fails, the patient may experience a sudden decrease in insulin delivery, leading to a potential rise in blood glucose levels. This can trigger diabetic ketoacidosis, characterized by hyperglycemia, ketosis, and acidosis. Monitoring for signs such as increased thirst, frequent urination, fruity breath odor, and rapid breathing is crucial.
Incorrect choices:
A: Adrenal insufficiency is not directly related to insulin pump failure.
C: Hyperosmolar, hyperglycemic state is more common in type 2 diabetes and typically occurs with extreme hyperglycemia, not sudden pump failure.
D: Hypoglycemia is less likely with pump failure due to decreased insulin delivery.
