Exam 1
-prandial elevation of blood sugar levels after food consumption
Glyconeogenesis Process of producing glucose from fat and protein
Ketones Byproducts of fat metabolism used for energy.
Insulin a hormone that promotes passage of glucose across cell membrane
alpha cells produces the hormone glucagon in response to low blood sugar levels
Glycogenolysis breakdown of glycogen to glucose in liver
counter regulatory hormones glucagon, epinephrine, cortisol, growth hormone which increase blood sugars
basal amount of insulin required to manage normal blood sugar levels
beta cells produces protein insulin in response to high blood sugar levels
Glucagon pancreatic hormone that helps release stores glucose in liver
Glycogen stored glucose in liver
fasting blood glucose normal range less than 100
prediabetes fasting glucose 100-125 mg/dL
Normal A1C 5-5.7%
A1C prediabetes 5.7-6.4%
A1C diabetes greater than 6.5%
ABC goals for diabetes A- A1C less than 7
B- blood pressure less than 140/90
C- cholesterol ldl- less than 100, triglycerides less than 150, HDL- greater than 40 for men and 50 for women
S- stop smoking
rapid acting insulin Aspart, lispro, glulisine (novolog, humalog, apidra)
onset of rapid acting insulin 15 min
peak for rapid acting insulin 2 hours
duration of rapid acting insulin 3-5 hours
short acting insulin Novolin R, Humulin R
onset of short acting insulin 30 minutes
peak of short acting insulin 3 hours
duration of short acting insulin 5-7 hours
intermediate acting insulin NPH (Novolin N, Humulin N)
Onset of NPH 1.5 hours
Peak of NPH 8 hours
Duration of NPH 16-24 hours
Long acting insulin glargine (Lantus)
detemir (Levemir)
onset of long acting insulin lantus 2-4 hours
levemir 1-2 hours
peak of long acting insulin there is no peak
duration of long acting insulin 24 hours
premixed insulin 70/30 first number is intermediate second number is regular
what insulin can be given IV? regular
how to store insulin Keep in refrigerator until opened.
discard after 28 days
what is the renal threshold 200 mg
polyuria excessive urination
polydipsia excessive thirst
polyphagia excessive hunger
Normal OGTT level <140 mg/dL
type 1 diabetes beta cells destroyed, doesn't produce insulin
DKA ketone production by liver out spaces ketone loss by kidneys, causes dehydration.
Signs of DKA (diabetic ketoacidosis) abdominal pain, acetone breath, kussmaul respirations, n/v, altered mental status. only occurs in type 1
treatment of dka correct dehydration first, electrolyte loss, watch for fluid overload and give IV insulin
IV insulin for DKA don't stop until subq is given and patient can eat
type 2 diabetes due to excess liver glucose production, insulin resistance, decrease insulin resistance and altered production of hormones
dx of type 2 obesity, genetic, age (older), previous gestational diabetes, sedentary lifestyle, ethnicity, metabolic syndrome
metabolic syndrome abdominal obesity, hyperglycemia, sedentary lifestyle, hypertension >130/85, lipidemia triglycerides>150, HDL <40 for men <50 for women
HHS hyperglycemic-hyperosmolar state type 2 only! extracellular dehydration, mortality rate 40-70%, slow onset up to 2 weeks
Signs of HHS no ketones, osmolarity >310, BS>600, altered reflexes, seizures, jerking, paralysis
treatment of hhs hydration to lower plasma osmolarity 0.45 NSS or 0.9 NS
signs of hypoglycemia sweating, tremors, tachy, palpations, hungry, headache, memory lapse, numbness of lips and tongue, disoriented, seizures, difficult to arouse
rule of 15 treat with 15 cards, wait 15 minutes, check blood sugar, if less than 70 eat another 20-30 carbs
peripheral neuropathy muscle weakness, sensory loss, loss of balance, loss of fine motor, join dislocation, fractures
autonomic neuropathy painless ischemia, Ortho BP, tachy, decreased gastric emptying, nocturnal diarrhea, UTI, vaginal infections, hypoglycemia unawareness
sudomotor neuropathy increase in upper body sweating, dryness of feet
Glucophage (metformin) suppresses hepatic glucose production, take during meal time, help for 48 hours if getting contrast
sulfonylureas glyburide, glipizide stimulates beta cells for insulin secretion, give first before main meal, for type 2
Dawn phenomenon hormone surge between 2 and 8 am which leads to higher sugars in the morning
Somogyi effect medications cause blood sugar to crash while sleeping so body responds by secreting stress hormones that rescue you from low bs
Lipodystrophy atrophy of subcutaneous fat
thyroid hormones idodine needed to make hormone, regulated by tsh includes t3, T4 and calcitonin
congenital hypothyroidism thyroid hormone crosses the blood brain barrier and causes intellectual disabilities and stunted growth
Cretinism iodine deficiency during pregnancy and causes mental retardation, stunted growth, deafness and spasticity
symptoms of hypothyroidism weight gain, decreased appetite, lower body temp, cold interolerance, bradycardia, hypertension, constipation, hair loss, dry skin, fatigue, depression, impaired memory, muscle aches, slow speech
Myxedena Coma Hypothyroid emergency precipitated by stress, infection, undiagnosed hypothyroidism, didn't take medication, or use of opioids
signs of myxedema coma lower temp, lower respirations, lower BP, lower blood sugar, and unresponsiveness
treatment for myxedema coma IV thyroid replacement and steroids
causes of hypothyroidism Hashimoto's thyroiditis, iodine deficiency.
treatment of hypothyroidism levothyroxine, start small and titrate up, given on empty stomach at same time every day
Hyperthyroidism excessive activity of the thyroid gland, graves disease
hyperthyroidism symptoms weight loss, increased appetite, increased body temp, heat intolerance, tachycardia, palpations, arrhythmias, hypertension, diarrhea, anxiety, irritability, tremors, insomnia, sweating, hair growth, nail growth
treatment of hyperthyroidism radioactive iodine, beta blockers to help with cardiovascular symptoms, anti thyroid hormones, methimazole or tapazole
Thyroid storm when thyroid produces a large amount of thyroid hormone is a short period of time. can be caused by stress, trauma, infection or not treating hyperthyroidism
treatment for thyroid storm anti thyroid medicine, idonine solution, beta blockers, cooling blankets, oxygen, quiet room
