Diabetes - Chapter 26 Flashcards
Diabetes Mellitus
- A metabolic disorder characterized by hyperglycemia (high blood glucose) because:
- Pancreas does not produce any insulin
- Pancreas produces not enough insulin
- Cells of the body do not respond appropriately to insulin
Hormone Regulation of Blood Glucose Levels
- Glucose is obtained from digestion and absorption of ingested food and is also made in the liver and muscles
- Absorbed glucose is carried by the blood to all cells of the body
- B cells in the pancreas release insulin in response to rising blood sugar
Diabetes Complications
- Retinopathy
- Blindness
- Blurred vision
- Nephropathy
- Stroke
- Heart attack
- Hypertension
- Angina
- Hyperlipidemia
- Infections
- Amputations
- etc.
Types of Diabetes Mellitus
- Prediabetes
- Type 1 diabetes
- Type 2 diabetes
- Gestational diabetes
Prediabetes
-BG level higher than normal; 50% progress to diabetes
Type 1 Diabetes
- Autoimmune disease
- Immune system attacks and destroys B-cells resulting in a total lack of insulin production
Type 2 Diabetes
- Most common
- Pancreas does not produce enough insulin and/or cells become resistant to insulin
Gestational Diabetes
-Occurs in about 3-20% of all pregnant women
Risk Factors for Type 2 Diabetes
- Age
- Family history
- Genetics
- Having gestational diabetes
- Diagnosis of prediabetes
- High blood pressure
- High cholesterol
- Overweight
- Sleep apnea
Symptoms of Type 1 and 2 Diabetes Mellitus
- Hyperglycemia
- Extreme fatigue
- Increased thirst
- Frequent urination
- Constant hunger
- Weight loss
- Blurred vision
- Diabetic ketoacidosis
Diagnostic Tests for Diabetes
- Fasting blood glucose test
- Oral glucose tolerance test
- Random blood glucose
- Hemoglobin A1c
Lifestyle Modifications for Diabetes Mellitus
- Weight loss
- Physical activity
- Stop smoking
- Eat low glycemic index foods
Pharmacy Supplied Diabetic/Insulin Supplies
- Syringes
- Pen needles
- Blood glucose testing strips
- Lancets
- Alcohol swabs
- Sharps disposal
- Infusion sets for pumps
- Insulin pens
- Blood glucose meters
- Urine strips for ketones and/or glucose
Pharmacological Management of Diabetes Mellitus
- Insulin
- Sulfonylureas
- Biguanides
- a-Glucose inhibitors
- Meglitinides
- Thiazolidinediones
- Dipeptidyl peptidase-4 inhibitors
- Incretin mimetics
- SGLT2 inhibitors
Insulin
- Is the only drug administered for type 1 diabetes
- Administered subcutaneously, only regular insulin can be administered intravenously
- Measure in 100 units/mL
- Schedule II
Insulin Dosage Delivery Systems
- Vial
- Cartridge pen
- Prefilled disposable pan
- Pump
Insulin Storage Conditions
- Protect from extremes in heat and cold
- Refrigerate unopened vials
- Vial or pen in use may be stored at room temp for 28 days
Insulin Tech Note
- Regular insulin may be administered IV
- when mixing insulin in a single syringe, if one is cloudy, it gets drawn up second
- Rapid acting insulins cannot be mixed with other insulins

Insulin ADR’s
- Hypoglycemia
- Weight gain

- Fat accumulation or loss at injection site
- Hypokalemia
Symptoms of Hypoglycemia
- Shakiness
- Dizziness
- Nervousness
- Sweating a lot
- hunger
- Headache
- Pale face
- Passing out
Treatment Options for Mild to Moderate Hypoglycemia
- 15g glucose tables
- 15 mL table sugar dissolved in water
- 175 mL juice or regular soft drink
- 6 lifesavers
- 15 mL honey
Hypoglycemia Treatment if Patient is Unconscious
- Glucagon kit
- IV glucose
Diabetic Ketoacidosis (DKA)
- Is a life threatening condition; Cells cannot get the glucose needed for energy due to a lack of insulin
- High levels of glucose remain in the blood but cannot be transported into cells
- Ketone bodies enter the bloodstream, causing a chemical imbalance
Causes of DKA
- too low insulin
- Having a severe infection or other illness
- Severe dehydration
- Combination of these things
-Most common in type 1 but can occur in type 2
Symptoms of DKA
- Flushed, hot, dry skin
- Blurred vision
- Feeling thirsty and urinating a lot
- Drowsiness
- Rapid, deep breathing
- Strong fruity breath odour
- Loss of appetite, vomiting, etc.
- confusion
Sulfonylureas
-AKA oral hypoglycemic agents
