What is a Postprandial blood sugar (PPBS) test? Fasting client is given a measured amount of carbohydrate solution orally, followed by a blood glucose test 2 hours later to determine glucose metabolism.
A blood Glucose of what following a Postprandial blood sugar (PPBS) test indicates Diabetes Mellitus? Blood glucose > 160 mg/dl
What does the Glycosylated hemoglobin (HbgA1c) test measure? Measures the amount of glucose bound to hemoglobin within the RBC
What is the normal % of glucose bound to hemoglobin? 4% - 6%

What percentage of the daily intake of kcals should come from fat in the diabetic diet? No more than 30 % total kcals from fat
What should diabetic PTs carry while excersizing? Client should carry a form of “easy to eat” Carbohydrates in case hypoglycemia occurs during exercise

What times during the day is NPH/Regular insulin taken? *Usually take NPH/Regular insulin BID at Breakfast and Dinner *Regular insulin is used at lunch and bedtime to cover meal/snack
In the case of mixed insulin, which insulin is ALWAYS drawn first? Regular insulin
What must the Diabetic PT have in order for oral hypoglycemics to be effective? Client must have some functioning insulin production for these medications to be effective
What do Oral Hypoglycemics do to reduce blood glucose? stimulate the beta cells to produce insulin
Why should regular insulin NOT be injected into the muscle? enters the bloodstream too quickly and could cause hypoglycemia
What subcutaneous injection site provides the fastest, least variable absorption? Abdomen
Rotating injection sites prevents what? lipodystrophy
True or False: Due to reduced nerve sensation and susceptability to infection, a PT with Type-2 diabetes should keep their feet dry and barefoot as much as possible to reduce blisters and stagnation. False. Client should NOT go barefoot at any time.
What is neuropathy? Any abnormal condition characterized by inflammation and degeneration of the peripheral nerves
