Problem: Johnathan has type I diabetes and plays baseball for his university. The Nurse Practitioner assesses a knowledge deficit about his insulin and his diagnosis. He should be taught that:
1) Each brand of insulin has equivalent bioavailability
2) He should increase his carbohydrate intake during times of exercise
3) Alcohol can cause hypoglycemia, and in small amounts can control diabetes
4) Injectable medications can be substituted with oral hypoglycemics
