Nursing Management for Diabetes Mellitus Nursing Management for Diabetes Mellitus Presentation Transcript

  • DIABETES MELLITUS Nelia S. Bañaga – Perez RN, MSN, MAEd Northeastern College Nursing Department Santiago City, Philippines
  • DIABETES MELLITUS
    • An endocrine disorder in which there is insufficient amount or lack of insulin secretion to metabolize carbohydrates.
    • It is characterized by hyperglycemia, glycosuria and ketonuria.
  •  
  •  
  • Diabetes Mellitus Pathophysiology
    • The beta cells of the Islets of Langerhan of the Pancreas gland are responsible for secreting the hormone insulin for the carbohydrate metabolism.
    • Remember the concept - sugar into the cells.
  • Diabetes Mellitus Types
    • Type 1 - IDDM
      • little to no insulin produced
      • 20-30% hereditary
      • Ketoacidosis
    • Gestational
      • overweight; risk for Type 2
    • Type 2 - NIDDM
      • some insulin produced
      • 90% hereditary
    • Other types include Secondary Diabetes :
      • Genetic defect beta cell or insulin
      • Disease of exocrine pancreas
      • Drug or chemical induced
      • Infections- pancreatitits
      • Others- steroids,
  • INSULIN
    • Insulin is a protein made of 2 chains- alpha and beta
    • Preproinsulin is produced initially
      • Precursor molecule that is inactive
      • Must be made smaller before becoming active
    • Proinsulin
      • Precursor that includes alpha and beta chains
      • Also has a C-peptide chain
      • C-peptide levels are used to measure rate that beta cells secrete insulin
  • INSULIN
    • Insulin allows glucose to move into cells to make energy
    • Liver is first major organ to be reached
      • Promotes production and storage of glycogen (glycogenisis)
      • Inhibits glycogen breakdown into glucose (glycogenolysis)
      • Increases protein and lipid synthesis
      • Inhibits tissue breakdown by inhibiting liver glycogenolysis (ketogenesis- converts fats to acids) & gluconeogenisis (conversion of proteins to glucose)
      • In muscle, promotes protein and glycogen synthesis
      • In fat cells, promotes triglyceride storage
  • INSULIN
    • Pancreas secretes 40-50 units of insulin daily in two steps:
      • Secreted at low levels during fasting ( basal insulin secretion
      • Increased levels after eating (prandial)
      • An early burst of insulin occurs within 10 minutes of eating
      • Then proceeds with increasing release as long as hyperglycemia is present
  • GLUCOSE HOMEOSTASIS
    • Glucose is main fuel for CNS
    • Brain cannot make or store, therefore needs continuous supply
    • Fatty acids can be used when glucose is not available ( triglycerides)
    • Need 68-105 mg/dL to support brain
    • Decreased levels of glucose, insulin release is stopped with glucagon released
  • GLUCOSE
    • Glucagon causes release of glucose from liver
      • Liver glucose is made thru glycogenolysis (glucogen to glucose) &
      • Gluconeogenesis
    • When liver glucose is not available, lypolysis occures ( breakdown of fat) OR
    • Proteinlysis (breakdown of amino acids)
  • ABSENCE OF INSULIN
    • Insulin needed to move glucose into cells
    • Without insulin, body enters a state of breaking down fats and proteins
    • Glucose levels increase (hyperglycemia)
  • Absence of Insulin
    • Hyperglycemia
    • Polyuria
    • Polydipsia
    • Polyphagia
    • Hemoconcentration, hypervolemia, hyperviscosity, hypoperfusion, and hypoxia
    • Acidosis, Kussmaul respiration
    • Hypokalemia, hyperkalemia, or normal serum potassium levels
  • Assessment
    • History
    • Blood tests
      • Fasting blood glucose test: two tests > 126 mg/dL
      • Oral glucose tolerance test: blood glucose > 200 mg/dL at 120 minutes
      • Glycosylated hemoglobin ( Glycohemoglobin test) assays
      • Glucosylated serum proteins and albumin
    • FSBS – (finger stick) monitoring blood sugar
  • Urine Tests
    • Urine testing for ketones
