Endocrinology Flashcards
what lab test is used in diabetic patients to assess the adequacy of gloycemic control over the last three months?
HgbA1c
what is the leading cuase of death in diabetics?
CV disease
why must beta blockers be used with caution in diabetics
blcoks symptoms of hypoglycemia
what can cause hypoglycemia in nondiabetic patient?
insulinoma, iatrogenic, fasting, alcohol, pit/adrenal insufficiency
what are the underlying metabolic derangements in type 2 diabetes
incrs hgbAic
increased glucose
insulin resistance and deficiency
five categories for metabolic syndrome
abd obesity
triglycerides
HDL
BP
glucose
skin finding which can be a sign of insulin resistance
acanthosis nigricans
lifestyle changes for type 2 DM? drug recommended as first line therapy for these patients?
wt loss, increased exercise, diet
metformin
which type of insulin is used in continuous infusion insulin pumps and tx of DKA
insulin lispro/aspart
reg insulin
which diabetic medications should be avoided in patients with heart failure?
TZDs
Which medication from metformin, pioglitazone and glyburide is most likely to cause hypoglycemia
glyburide
mechanism of action of diabetes drug which decreases GI absorption of starch and disaccharides
acarbose
mechanism of action of diabetes drug which stimulates insulin release
sulfonylurea, meglitinides
mechanism of action of diabetes drug which decreases hepatic gluconeogenesis
metformin, TZDs
mechanism of action of diabetes drug which increases tissue glucose uptake and improves insulin sensitivity
TZDs, metformin
mechanism of action of diabetes drug which mimics action of GLP1, decr glucagon, incr insulin, delays gastric emptying
GLP1 agonist
mechanism of action of diabetes drug which inhibits DPP4 leading to decr glucagon, incr insulin, delayed gastric emptying
DPP4 inhibitor
mechanism of action of diabetes drug which increases urinary elimination of sugar
SGLT2 inhibitor
antidiabetic agent associated with lactic acidosis
metformin
which serum electrolytes are commonly low in patients with DKA
total body K, HCO3, Ca/Mg, Na, phosph
type 2 DM ran out of metformin, presents with 3 daysd of polyuria, dry mouth, vomiting. lethargic. Na 144, K 3.7, Cl 101, HCO3 18, glucose 413. Dx? Further testing?
DKA
abg and urine or serum ketones
antihypertensive drug class that reduces proteinuria and slows diabetic nephropathy
ACEI or ARB
treatment of proliferative diabetic retinopathy?
surgical, photocoag
treatment of peripheral neuroapthy?
amitryptilline, duloxetine, carbamazepine, gabapentin, pregabalin
common eye diseases in diabetics?
retinopathy, glaucoma, cataracts
tx and dx or diabetic gastroparesis
gastric emptying study
erythromycin, metoclopramide
tx for DKA
fluids, reg insulin, KCl
thyroid abnormalities in pregnancy?
increased TBG, increased total T4, normal free T4
patient has exophthalmos, What is the most likely cause?
hyperthyroid, Graves disease
treatment of the most common cause of hyperthyroidism
radioactive I
met, PTU, surgery
patient has exophthalmos, pretibial myxedema decreased zTSH, dx?
graves dx
major differences between de quervain thyroiditis and hashimoto
de quervain: decr TSH, incr T4, painful goiter
hasthimoto: incr TSH, decr T4, painless goiter
most common type of thyroid cancer
papillary
next step in management of newly found thyroid nodule in a patient with hyperthyroidism
check TSH, free T4
radioactive iodine scan
Vit D deficiency: Ca, PTH, phosphate
decr Ca, incr PTH, decr phosphate
