Diabetes Altered LOC

Thurston County EMT
Show Answers:

  1. What does the pancreas do and where is it located?
    • secretes insulin, glucose and glucagon
    • located mostly in the upper L quadrant
  2. What is glucose?
    • a simple carbohydrate (sugar)
    • used by the body to produce energy
    • major nutrient source
    • every carb must be broken down to glucose in order for the body to use it
  3. What is hypoglycemia?
    when the blood sugar is low enough to cause CNS symptoms (affecting the brain)
  4. What does the liver secrete?
  5. What is glycogen?
    stored sugar, or extra sugar left over from a previous meal
  6. What does insulin do?
    allows glucose to enter the cell and decreased the bG
  7. Define hyperglycemia and the symptoms associated with it.
    • increased glucose in the blood caused from lack of insulin allowing the glucose to enter the cell
    • in short: too much food, too little insulin
    • rapid weak pulse
    • deep rapid breathing
    • decreased LOC
    • normal or lowered BP
  8. Define Type I Diabetes
    • insulin dependent = pancreas cannot create enough insulin, so these pts must take supplemental insulin
    • most common form in young ppl
    • 10-15% of diabetes cases
  9. Define Type II Diabetes.
    • Non-insulin dependent
    • most common type of diabetes in ppl over 30 y/o
    • frequently associated with obesity b/c the body mass grows but the pancreas does not = it has insufficient insulin secretion
    • these pts take oral medications to stimulate the pancreas to create more insulin (they may also take insulin as well)
  10. In diabetes, the cell responds to starvation by...
    metabolizing fat instead of glucose
  11. What are the negative effects of the cell metabolizing fat instead of glucose?
    • byproducts of fatty acids and ketones, making the patient severely acidotic (changing the pH in the body)
    • can cause severe brain damage or death
    • kidneys attempt to eliminate glucose through urine and cause dehydration
  12. How does the patient try to correct acidosis caused from fat metabolization?
    • deep rapid breathing pattern called Kussmaul's respirations
    • pt breathes off CO2 and the blood becomes more alkaline
  13. What are the signs and symptoms of Diabetic Ketoacidosis?
    • hunger (cells are starving)
    • thirst (excessive urine output)
    • tachycardia and hypotension from excessive urine output
    • pale, dry skin
    • altered LOC
    • dehydration
  14. What are the complications resulting in a patient with diabetic ketoacidosis?
    • electrolytes are imbalances from an excessive urine output and potassium levels drop
    • acidosis and decreased potassium may cause cardiac dysrhythmia or death
  15. How do we treat diabetic ketoacidosis?
    • recognize it
    • ALS upgrade
    • support ABCs
    • correct hypovolemia
    • rapid transport where the pt will be placed in insulin and the volume loss will be replaced
  16. The ____ is the only organ that doesn't require insulin to use glucose
  17. List the s/s of hypoglycemia.
    • full, rapid pulse
    • normal breathing
    • dizziness, headache
    • fainting, seizures, disorientation, coma
    • normal BP
    • pale
    • grossly diaphoretic
    • if allowed to progress, pt will become tachycardic (brain wants more blood - more sugar) and brain cells will begin to die from starvation
  18. What are the complications associated with hypoglycemia?
    • pt appears intoxicated
    • any CNS disturbance possible: coma, confusion, euphoria, combativness
    • if not recognized and corrected quickly, permanent brain damage may result (brain cells are dying from starvation)
  19. What can are the things that atheroschlerosis can cause?
    • Coronary Artery Disease
    • claudation (limping)
    • skin breakdown
    • infection
    • amputation of extremities
  20. What are the indications for the use of glucose?

    • known diabetic who has not taken medications for days
    • patient is unable to swallow
  22. What are the precautions/adverse reactions when administering glucose?
    use caution to prevent aspiration of glucose paste
  23. What class of drug is glucose?
  24. What are the two methods of glucose administration?
    • squeeze small portions of gel into mouth between cheek and gum
    • squeeze small portions of gel into tongue depressor, then place gel between cheek and gum
  25. What should an EMT be concerned with just after administering glucose?
    Blood Glucose Rebound - in the presence of insulin, glucose introduced into the bloodstream will be flushed rapidly into cells and cause the bG to drop rapidly again. to prevent another hypoglycemic episode, the pt must eat a carb and protein (pb&j)
  26. What are the questions to ask a diabetic pt (or family member)?
    • are you on oral medication or insulin?
    • have you taken your meds today?

    • what was the result of the bG test?
    • any other symptoms?
  27. What should an EMT keep in mind when checking glucometry?
    • a tool that should be used to supplement an ALS assessment
    • should not be a decision point in determining upgrade or method of transport
    • BLS units should not carry glucometers not base any decisions to upgrade or downgrade a ptbased on bG reading
