quiz 10 Flashcards
dawn phenomenon
early morning rise (5-6am) in blood glucose due to nighttime release of adrenal hormones
- can be managed by providing more insulin for overnight period
diabetes mellitus
chronic hyperglycemia resulting from impaired processes in glucose metabolism that include reduced insulin secretion or reduced insulin action or both
- chronic, common, complex disorder of impaired nutrient metabolism, specifically glucose, that impairs function of the body system
FBS > or = 126 mg/dL, casual test greater than 200 mg/dL
type 1 immune cells/antibodies destroy insulin secreting cells
type 2: more common, insulin resistance that is developed
diabetic ketoacidosis
- excessive breakdown of fatty acids
- caused by absence of insulin and inc in hormone release that leads to increased liver and kidney glucose production
severe, acute complication of diabetes that is characterized increased production of ketones, uncontrolled hyperglycemia, and metabolic acidosis - symptoms: polyuria, polydipsia, polyphagia, fruity breath, vomiting, abdominal pain, dehydration, weakness, confusion, shock, coma
diabetic peripheral neuropathy
progressive deterioration of nerve function with loss of sensory perception
- pain, muscle weakness, foot ulcers, organ dysfunction
- distal symmetric polyneuropathy (sensory, motor) and autonomic neuropathy (GI, cardiovascular, nephropathy)
gestational diabetes mellitus
high blood sugar with onset during pregnancy
- hormone made by the placenta prevents body from using insulin effectively
glucosuria
glucose in the urine
- causes: diabetes, eating too much glucose
hemoglobin A1c
a standardized test that measures how much glucose permanently attaches to a hemoglobin molecule, and is used to check the effectiveness of a blood glucose level
hyperglycemia
high blood glucose levels
- FBS > or = 126 mg/dL, casual test greater than 200 mg/dL
- dry mouth, increased thirst, weakness, headache, blurred vision, frequent urination
hypoglycemia
low blood glucose levels
- less than 70 mg/dL
- hunger, irritability, sleepiness, sweating, pallor
hypoglycemia unawareness
in pt w/ DM type 1: when pt no longer have warning symptoms of early hypoglycemia, which is needed to prompt preventative action
in pt w/ DM > 30 years
can also occur in pt w/ DM type 2
hyperosmolar hyperglycemia syndrome
a severe acute hyperosmolar state caused by hyperglycemia
polyphagia
excessive eating
somogi effect
fasting hyperglycemia with prior hypoglycemia (morning hyperglycemia with the counterregulatory response to nighttime hypoglycemia)
