a. Withhold the usual scheduled insulin dose because the patient is NPO.
b. Obtain a blood glucose measurement before any insulin administration.
c. Give the patient the usual insulin dose because stress will increase the blood glucose.
d. Administer a lower dose of insulin because there will be no oral intake before surgery.

It is not possible to predict whether the patient will require no insulin, a lower dose, or a higher dose without blood glucose monitoring.
