NR601 Final Concept Review
Diabetes
– Physiology
o Prediabetes: impaired glucose tolerance
o Type 1: autoimmune destruction of pancreatic beta cells leading to
ketoacidosis and lack of insulin
o Type 2: insulin resistance and impaired insulin secretion by islet cells of
pancreas and decline of beta cell function
– Assess:
o Height/Weight
o BP
o CV assessment
o Thyroid
o Ophthalmic
o Peripheral
o Feet/skin
o Neuro
o Oral
– Diagnosis
o A1C > 6.5%
o Random glucose level of 200 or more in the presence of classic symptoms of
hyperglycemia
o Fasting plasma glucose of > 126 on two separate occasions
o Two-hour postload plasma glucose of 200 during OGTT (75g glucose)
Table 14-2 Kennedy – Memorize this *very important*

Treatment
– Labs
o Annually
▪ CMP

– Type 1: glargine (Lantus)- long acting, few hypoglycemic reactions
– Type 2:
,3
o Glucophage (Metformin)
▪ Dosage
▪ Side effects
▪ Education
▪ Hgb A1C > 9% = needs adjunct therapy
o Need to be on aspirin if over age 40 and not contraindicated
o ACEIs is needed if they are hypertensive
Risk Factors
– Family history

– Men vs Women
