"I can have an occasional beverage with alcohol if I include it in my meal plan." d. "I will eat something at meal times to prevent hypoglycemia, even if I am not hungry."

b. I can choose any foods, as long as I use enough insulin to cover the calories. most patients with type 1 diabetes need to plan diet choices very carefully. Patients who are using intensified insulin therapy have considerable flexibility in diet choices but still should restrict dietary intake of items such as fat, protein and alcohol.

Chooses a puncture site in the center of the finger pad. c. Hangs the arm down for a minute before puncturing the site. d. Says the result of 120 mg indicates good blood sugar control.

"I will not need to worry about hypoglycemia with the Byetta." c. "I should take my daily aspirin at least an hour before the Byetta." d. "I will take the pill at the same time I eat breakfast in the morning."
