Q

Dawn phenomenon

Study These Flashcards
A

Relatively normal blood glucose level until approximately 3am, when blood glucose levels begin to rise. (Thought to result from nocturnal surges in growth hormone secretions, which create a greater need for insulin in the early morning hours in patients with type 1 diabetes.)

20
Q

Somogyi effect

Study These Flashcards
A

Normal or elevated blood glucose at bedtime, a decrease at 2 to 3am to hypoglycemic levels, and a subsequent increase caused by the production of counter regulatory hormones.

21
Q

Oral diabetic medications

Study These Flashcards
A

Bigaunides: Metformin
Sulfonylureas:
2nd- Glipizide, Gluburide, Glimepiride
1st- Chlorpropamide, Tolazamide, Tolbutamide (not used)
Nonsulfonylurea Insulin Secretagogues: Repaglinide, Neteglide
Thiazolidinediones (TZDs): Pioglitazone, Rosiglitazone
Alpha-Glucosidase Inhibitors: Acarbose, Miglitol
Dopamine Agonists: Brocriptine
SGLT2 Inhibitors: Camagliflozin, Dapagliflozin
DDP4 Inhibitors/Incretin Enhancers: Sitagliptin, Saxaglipton, Exenatide

22
Q

Biguanides

Study These Flashcards
A

no hypoglycemia
Action: Does NOT stimulate insulin release- decreases liver glucose release and cellular insulin resistance, which makes blood sugar go down.
Contraindication: renal/liver disease, alcoholism, severe CHF, over 80, with contrast dye or anesthesia
AE: muscle cramps (lactic acidosis), N/V, diarrhea.

23
Q

Sulfonylureas

Study These Flashcards
A

yes hypoglycemia
Action: Directly stimulates beta cells of pancreas to secrete insulin and improve insulin action at the cellular level
Contraindication: alcohol (causes severe N/V), sulfa allergy
AE: hypoglycemia, nausea, heartburn, weight gain

24
Q

Thiazolidinediones (TZDs)

Study These Flashcards
A

no hypoglycemia
Action: Enhances insulin action and glucose utilization in peripheral tissues
Contraindication: Liver failure (monitor before starting and periodically)
AE: impair liver function, reduce effectiveness of contraceptives, cause MI/HF (hyperlipidemia), anemia, impaired platelet function, weight gain, edema

25
Alpha-Glucosidase Inhibitors
*no hypoglycemia* Action: delay the absorption of glucose in the intestines- slow entry of glucose into systemic circulation, do not increase insulin secretion. Must be taken with first bite of food. Contraindication: GI or renal dysfunction, cirrhosis AE: abdominal discomfort/ distension, diarrhea, flatulence
26
Nonsulfonylureas Insulin Secretagogues
*yes hypoglycemia* Action: Stimulate rapid onset and short duration of insulin secretion from the pancreas. Take about 15 minutes before meals Contraindication: renal/ liver dysfunction and alcohol AE: hypoglycemia, weight gain (less likely than sulfonylureas)
27
SGLT2 Inhibitors
*no hypoglycemia* Action: Blocks re-uptake of glucose in the kidneys (force the kidneys to release more glucose into the urine) Contraindications: renal dysfunction AE: dehydration, kidney failure, slightly more prone to UTIs
28
DDP4 Inhibitors
*yes hypoglycemia* Action: Enhances glucose-dependent insulin secretion by the pancreatic beta-cell, suppresses inappropriately elevated glucagon secretion, and slows gastric emptying AE: hypoglycemia, nausea, diarrhea, acute pancreatitis, weight loss
29
Hypoglycemia
diaphoresis, trembling, dizziness, irritability, headache, confusion, drowsiness/fatigue, slurred speech --> seizure, coma death *Cold and clammy need some candy*
30
Hypoglycemia treatment
15grams of carbohydrate 25 to 50 mL D50W 1mg Glucagon IM or subQ
31
Hyperglycemia
increased thirst, dry mouth, headaches, difficulty concentrating, blurred vision, frequent urination, fatigue (weak or tired), irritability --> DKA/HHNKS *Hot and dry sugar high*
32
Diabetic Ketoacidosis
Relative or absolute lack of insulin which leads to hyperglycemia, ketosis (fat is metabolized to produce ketones in the blood and urine), acidosis, BUN and Creatinine increase, Kussmaul respirations, osmotoic diuresis/dehydration, electrolyte loss, weakness/hypotension, N/V, abdominal pain, lethargy/coma/death
33
DKA diagnostic findings
GLucose > 250, serum pH 6.8-7.3, low serum bicarb, serum and urine ketones, glucose in the urine (renal threshold 180-200), abnormal electrolytes, fruity (acetone) breath
34
Treatment of DKA
Fluid replacement, insulin IV infusion, restore electrolytes (insulin carries potassium into cells), reverse acidosis (change IV fluids to D5W when glucose hits 250), monitor urine output
35
Hyperglycemic Hyperosmolar Non Ketotic Syndrome
Very high blood sugars: >600-800, absence of ketosis (still some insulin available), high blood osmolarity >350, dehydration and electrolyte loss
36
HHNS treatment
Fluid loss could be 10L or more, replace 1/2 of estimated loss in the first 12 hours, IV insulin, monitor electrolytes
37
Features of hyperthyroidism
*fast, wet, and restless* increased sympathetic nervous system, increased HR, hypertension, palpitations, dysrhythmias, increased metabolism, weight loss, heat intolerance, diaphoresis, thinning hair, rapid shallow breathing, muscle weakness and wasting, weakness/tremors, fatigue/ sleep disturbance, goiter, exopthalmos, lid lag, photophobia, irritability and restlessness, emotional lability, amenorrhea
38
Hyperthyroidism drug therapy
Anti thyroid agents: Propylthiouracil (PTU), Methimazole (Tapazole), Carbimazole, Lithium Iodine preparations: Strong iodine (Lugol's solution), Saturated solution of potassium iodide (SSKI), Potassium iodide tablets, solution or syrup
39
Propylthiouracil
Blocks synthesis of hormones (conversion of T3 to T4) | AE: rash, N/V, agranulocytosis, lupus syndrome, hypothyroidism, increased risk for infection and delayed healing
40
Methimazole
Blocks synthesis of thyroid hormone | AE: more toxic than PTU, watch for rash, N/V, agranulocytosis, hypothyroidism, etc.
41
Potassium iodide
Suppresses release of thyroid hormone. | AE: Discontinue for rash, can produce iodinism: lacrimation, salivation, stuffy nose, acne
42
Features of hypothyroidism
*thick, slow, and swollen* weakness, lethargy, fatigue, dry skin/ coarse hair brittle nails, thick tongue/hoarse voice, cold intolerance, constipation/weight gain, mental impairment, muscle cramps/slow muscle movements, depression/blank expression, bradycardia/dysrhythmias/cardiomyopathy edema of eyelids, face, legs, hearing loss, menorrhagia, slowing of return phase of reflexes, goiter
43
Myxedema coma
life threatening emergency! | coma, respiratory failure, hypotension, hypothermia, hyponatremia, hypoglycemia, shock, organ failure and death
44
Features of hyperparathyroidism
"Moans, groans, stones, and bones" Gastrointestinal: peptic ulcers, N/V, pancreatitis, constipation, anorexia Renal: kidney stones Skeletal: bone pain, osteoporosis, spontaneous fracture, weakness Mental: depression, anxiety, sleep disturbances, psychosis, coma High levels of PTH along with hypercalcemia and hypophosphatemia
45
Features of hypoparathyroidism
Symptoms related to hypocalcemia: tingling, muscle cramps, tetany and convulsions Positive Chvostek's and Trousseau's signs
46
Features of Anterior Hypopituitarism
Depend on the cause and hormone affected, but general fatigue, weakness, sensitivity to cold, decreased appetite, weight loss, abdominal pain, low BP, HA, visual disturbances, loss of armpit/pubic hair, cessation of periods, infertility, failure to lactate, decreased libido, loss of body/facial hair
