  27. The principal stimulus for insulin release is
    glucose in the bloodstream
  28. Insulin is an ________hormone
  29. Insulin deficiency puts the body into a _______mode
    Catabolic mode

    • resulting in glycogen converted to glucose
    • protiens degraded to amino acids
    • fats converted to glycerol and free fatty acids
  30. Insulin deficiency promotes

    • by increasing glycogenosis and gluconeogenesis and
    • decresing glucose utilization
  31. What insulins have a very rapid onset and short duration
    • Insulin lispro
    • Insulin aspart
    • Insulin glulisine
  32. Lispro Insulin solution is a

    Rapid-acting analog or regular insulin
  33. Lispro effects begin
    15-30 minutes of Sub-Q injection
  34. Lispro persist for
    3-6 hrs
  35. Insulin Aspart is a

    is an analog of human insulin with a rapid onset
  36. Insulin Aspart onset is
    10-20 minutes
  37. Insulin Aspart duration is
    Short 3-5 hours
  38. Regular (native) Insulin when used sub Q has a moderately _____onset and _____duration
    • rapid onset
    • short duration
  39. NPH and Detemir insulin have _____durations
  40. Insulin Glargine has a ________duration
    prolonged duration
  41. Insulin Glargine has _______peak
    no definite Peak

  43. Regular insulin can be administered
    IV and IM as well
  44. NPH insulin looks
    cloudy and should be gently agitated before being drawn into a syringe
  45. When using short-acting insulin in combination with longer-acting insulin it is usually desirable to mix
    the preparations in a single syringe, rather than inject them seperately
