  • 6. D IABETIC EMERGENCIES
  • 7. Diabetes K EY TERM Condition brought about by decreased insulin production, which prevents the body’s cells from taking the simple sugar called glucose from the bloodstream
  • 8. Insulin allows sugar to pass from the bloodstream into the cells.
  • 9. Diabetes is treated with injections of insulin or oral medications.
  • 10. Diabetic patients test their blood glucose at home.
  • 11. Blood Glucose Meters
  • 12. Prepare blood glucose meter and test strip.

  • 16. Read blood glucose test results.
  • 17. Blood Glucose Readings 80-120 mg/dl Normal 60-80 mg/dl Moderate hypoglycemia Below 50 mg/dl Severe hypoglycemia Above 140 mg/dl Hyperglycemia Question results that are inconsistent with patient’s condition.
