A client with type 2 diabetes asks what blood glucose level range is generally recommended before meals for adults. Which is CORRECT?

  1. A Less than 60 mg/dL
  2. B 80-130 mg/dL before meals (and less than 180 mg/dL two hours after meals) for most non-pregnant adults with diabetes, per ADA guidelines
  3. C Less than 200 mg/dL at all times
  4. D 300-400 mg/dL

Why this is the answer

BLOOD GLUCOSE TARGETS for adults with diabetes are established by the American Diabetes Association (ADA) in annual Standards of Medical Care in Diabetes. For most NON-PREGNANT ADULTS with diabetes: PREPRANDIAL (before meals): 80-130 mg/dL; POSTPRANDIAL (2 hours after the start of a meal): less than 180 mg/dL; A1c: less than 7% for most non-pregnant adults. INDIVIDUALIZED TARGETS: more stringent (lower) for: younger patients with long life expectancy, no significant cardiovascular disease, short duration of diabetes, no hypoglycemia history; less stringent (higher) for: elderly patients, history of severe hypoglycemia, advanced complications, limited life expectancy, extensive comorbidities. HYPOGLYCEMIA (low blood sugar): less than 70 mg/dL; symptomatic: shakiness, diaphoresis, pallor, confusion, palpitations, hunger; TREATMENT: RULE OF 15 — give 15 grams of fast-acting carbohydrates (4 oz juice, 4 oz regular soda, glucose tablets), recheck in 15 minutes; if still below 70, repeat; if unconscious or NPO, glucagon or IV dextrose. HYPERGLYCEMIA symptoms: polyuria, polydipsia, polyphagia, fatigue, blurred vision; acute crises: DKA (type 1, sometimes type 2) and HHS (type 2). SELF-MONITORING: teach clients how to use glucometer; proper technique (clean finger, lancet, test strip); documentation; when to call provider. DISEASE MANAGEMENT: medication adherence (oral agents, insulin), diet (consistent carbohydrate intake with attention to glycemic index), physical activity (lowers blood glucose), stress management (stress hormones raise blood glucose), regular provider follow-up, foot care, annual eye and renal exams.
