notes 465- DM, thyroid, anemia Flashcards
diagnosis of DM
FPG 7 or more, A1C 6.5 or more, 2hPPG or any random glucose over 11.1
when might urine ketone testing be used
pregnancy, acute illness or stress, preprandial over 14, DKA sxpresent
eligibility for TPA in stroke
presents within 3 hours of sx onset. CI- rapidly improving, hemmorhage, seizure with stroke, recent stroke or head injury in last 3 months, recent GI bleed, low platelets, BP over 185, recent anticoag (2 days)
if not eligible for TPA in a stroke, what do you give
if hemorrhage ruled out, give antiplatelet (aspirin). BUT, if assumed cardioembolic (Afib, mechanical valve, severe CHF) might get anticoag instead
what are patients who just had a stroke at high risk of
DVT- must provide proph (LMWH, UFH)-can be used 48 hours after hemorrhagic
first line drugs to treat BP in someone after acute phase of stroke
thiazide and ace
do you treat high BP in acute phase of stroke (first 72 hours)
not usually- only if extreme like greater than 220. We want high pressure and blood flow
dipyradimole/ASA’s only indication is in
2’ stroke prevention (aggrenox)
when is radioactive iodine used? CI?
hyeprthyroid. CI in pregnancy and exopthalmus (can worsen)
2 drugs that can induce hypothyroidism
amiodarone and lithium
when to expect sx improvement with levothyroxine
2-3 weeks max at 6
definition of anemia (M/F)
M= less than 130, F= less than 120
heme vs non heme iron
heme-animals, better absorbed and more consistent, less affected by diet. non heme= plants, most supplements, needs acid to absorb
what increases absorption of iron
vitamin C (oranges, peppers)
enteric coated iron
decrease absorption, especially in patients with decreased gastric acidity
acronym for iron strengths
fish swim great (fumarate, sulfate, gluconate- 33,20,11, blue-red-green). Polysaccharide iron 100%
iron in kids
can be toxic. dose 3-6mg/kg/day divided TID
which parenteral iron needs test dose due to risk of anaphylaxis
dextran
how long do you continue therapy after anemia resolved
3-6 months to allow for store repletion. Hb increases about 10g/L per week, and is usually corrected in six
cockcroft gault equation
[(140-age)xABW}/[0.814xSCrmmmol/L] x0.85 if female
what does BNP indicate
fluid overload or increased stretch of heart muscle (heart failure)
which SU can be used up until dialysis? which must be stopped at 50?
gliclizide. Glyburide must be stopped
at what renal fx is metformin CI
less than 30- lactic acidosis
when are thiazides no longer effective for diuresis
less than 30ml/min
treatment of hyperkalemia
kayexelate (CI in obstructive bowel disease), if severe combo of calcium gluconate, glucose, insulin, sodium bicarb, sabutamol, kayex and possibly dialysis
