NR601 FINAL EXAM STUDY GUIDE Week 5: Glucose metabolism disorders Types of DM 1. Type 1- severe insulin deficiency resulting in reduction or absence of functioning beta cells in the pancreatic isl ... ets of Langerhans. This leads to hyperglycemia due to altered metabolism of lipids, carbs, and proteins. Initial s/s of hyperglycemia. Subjective findings- polyuria, polydipsia, nocturnal enuresis and polyphagia with paradoxical weight loss, visual changes and fatigue. Objective-dehydration(poor skin turgor and dry mucous), wt loss despite normal/increase appetite, reduction in muscle mass. DKA-fatigue, cramping, abnormal breathing 2. Type 2- Type 2 DM is characterized by the abnormal secretion of insulin, resistance to the action of insulin in the target tissues, and/or an inadequate response at the level of the insulin receptor. A patient may, however, present with pruritus, fatigue, neuropathic complaints such as numbness and tingling, or blurred vision. 3. Prediabetic- fasting glucose consistently elevated above the normal range but less than 100-125. Impaired glucose tolerance (IGT) state of hyperglycemia where 2 hr post glucose load glycemic level is 140-199 Diagnostic criteria- there are 4 lab-based criteria to confirm DM: A1C, random plasma glucose, fasting plasma glucose, and 2-hr post load plasma glucose  AIC of 6.5 or higher=diabetes  Random plasma glucose level of 200 WITH classic symptoms of hyperglycemia or a hyperglycemic crisis [Show More]
