Lecture 15A Diabetes in older adults Flashcards
The leading reason that the number and percentage of Americans diagnosed with diabetes has increased is _
Obesity.
Diabetes diagnosis rates by race/ethnicity
- American Indians/Alaskan Natives - 15.9%
- Non-Hispanic blacks - 13.2%
- Hispanics - 12.8%
- Asian Americans - 9.0%
- Non-Hispanic whites - 7.6%
According to the Framingham data, _ of those over 65 have diabetes mellitus or impaired fasting glucose.
40%.
Type 2 diabetes is especially prevalent among ethnic minorities due to increased _ within some ethnic groups.
Insulin resistance.
A diagnosis of type 2 diabetes may be made when laboratory results reveal _
- A fasting blood glucose of 126 mg/dL or higher.
2. An HbA1c of 6.5% or higher.
The American Diabetes Association (ADA) standards of care include _
- Annually: Dilated eye exam, monofilament foot exam, and immunizations.
- Recommended: Aspirin use, smoking cessation, and diabetes education.
The ADA target for HbA1c is _
7.0% or lower.
The ADA target for blood pressure is _
140/90.
The ADA targets for lipid levels are _
- LDL (“bad cholesterol”) below 100 mg/dL.
- HDL (“good cholesterol”) above 50 mg/dL.
- Triglycerides below 150 mg/dL.
The ADA target for GFR is _
60 mL/min.
A patient’s HbA1c level provides an indication of average blood glucose over the previous _
2-3 months.
A patient with an HbA1c below 7.0% has been maintaining a mean plasma glucose level of approximately _
150-160 mg/dL.
Since looser glycemic targets may be employed when dealing with older adults, most clinicians consider an HbA1c of _ to be acceptable for this age group.
7.5-8%
Advancing age enhances the risk of severe or even fatal hypoglycemia due to impaired _
Counter-regulatory hormones (e.g., glucagon).
Risk factors for hypoglycemia
- Older age.
- Renal insufficiency.
- Long-acting oral agents (e.g., sulfonylureas).
- Poor nutrition.
- Alcohol use.
- Congestive heart failure (CHF).
- Post-hospitalization or frequent hospital admissions.
- Polypharmacy.
Treatment of hypoglycemia (BG less than 70 mg/dL) in the inpatient setting
- Begin with 4-6 oz. of fruit juice (no added sugar), delivering a total of 15 g of glucose.
- Recheck the patient’s BG after 15 minutes, and give another 15 g of glucose if the patient’s BG remains low.
- The patient should eat a meal within the next hour after a hypoglycemic episode.
- If a patient has a BG level of 40-50 mg/dL or lower, they should receive glucagon rather than an oral sugar (this will not be enough).
Most older patients with diabetes will die of _
Cardiovascular disease (CVD).
Severe hyperglycemia in older people is likely to be _, due to dehydration.
Hyperosmolar hyperglycemic state (HHS) (not DKA).
Signs and symptoms of hyperglycemia
- Dehydration.
- Visual disturbances.
- Confusion.
- Urinary incontinence.
- Increased risk for falls.
Intake of _ should not be limited in older adults with poor appetites.
Carbohydrates.
“Carb consistent” diet
The proper name for a “diabetic” diet, in which the person has 45 grams of carbohydrates at each meal, and no snacks in between meals.
For people with underlying _, treatment for this condition is the #1 way to prevent/treat diabetes.
Depression.
Metformin (Glucophage)
- A biguanide that keeps the liver from releasing too much glucose.
- Major side effect is GI discomfort - take with food because the patient will have nausea/vomiting/diarrhea if they take it on an empty stomach.
- A safe drug for most patients because it does not cause hypoglycemia.
Sulfonylureas (Amaryl, Glucotrol) stimulate the pancreas to secrete more insulin, but they are not good for older adults because _
They potentiate hypoglycemia.
_ are similar to sulfonylureas, but are better for older adults because they carry a lower risk of hypoglycemia.
Meglitinides (Prandin, Starlix).
The best class of medications for diabetic kidney disease is _
DPP-IV inhibitors (Januvia, Onglyza, Tradjenta).
Early insulin therapy consists of continuing all oral medications and adding a once-daily basal insulin such as _
Levemir or Lantus.
NPH is a(n) _ acting insulin.
Intermediate.
Lispro and aspart are _ acting insulins.
Rapid.
Regular insulin is considered _ acting.
Short.
Detemir and glargine are _ acting insulins.
Long.
Insulin pens can be stored at room temperature for _ to _ days.
14 to 28 days.
Basal insulin
- The “background” insulin required to maintain target glucose values when a person is not eating.
- Examples: Levemir, Lantus, NPH.
Bolus insulin
- Mealtime or prandial insulin that is given “on demand” for meal coverage and to correct high blood sugar.
- Examples: Apidra, Novolog, Humalog, regular.
