A Patient with Type 2 Diabetes Achieves Adequate Glycemic Control

A patient with type 2 diabetes achieves adequate glycemic control through diet and exercise. Upon being admitted to the hospital for a cholecystectomy, however, the patient has required insulin injections on two occasions. The nurse would identify what likely cause for this short-term change in treatment?

A) Alterations in bile metabolism and release have likely caused hyperglycemia.
B) Stress has likely caused an increase in the patients blood sugar levels.
C) The patient has likely overestimated her ability to control her diabetes using nonpharmacologic measures.
D) The patients volatile fluid balance surrounding surgery has likely caused unstable blood sugars.
