New cards
EPO mechanism
released in response to hypoxia form kidneys (10% liver) and inhbits apoptosis to prevent early cell death AND proliferation thru JAK2
20
New cards
EPO side effects
iron deficiency (cant keep up so RBC draw iron from blood), thrombosis (dialysis patients need anticoagulant), hypertension (increased hematocrit and AT2), seizures
21
New cards
aldosterone effect
increases Na reabsorption in kidney and excretes K+
22
New cards
aldosterone triggers
low Na+ increase AT II
23
New cards
loop diuretics examples
furosemide, bumetanide
24
New cards
loop diuretic mechansm
inhibit NA/K/2Cl carrier so Na+ not reabsorbed and 2Cl and K+ pee out
25
New cards
loop diuretics adverse effects
excessive loss, hypovolemia, hypoklemia, alkalosis, hypomagnesaemia, hyperuricemia, reduced renal perfusion, hearing loss, rashes, bone marrow depression, contraindicated w sulfa allergy
compete w aldosterone to inhibit Na retention and K secretion
34
New cards
aldosterone antagonist adverse effects
hyperkalemia, GI upset, gynecomastia, menstrual disorders, testicular atrophy
35
New cards
triamterene/amiloride
prevent hypokalemia, inhibit Na reabsorption,
36
New cards
triamterene/amiloride adverse effects
hyperkalemia, GI upset
37
New cards
osmotic diuretics
only water excretion
38
New cards
osmotic diuretics adverse effects
risk for precipitating left ventricular fialure, headache, nausea, vomiting
39
New cards
electrolyte disorders
important in renal failure; hypoerphosphatemia; hyperkalemia
40
New cards
antihypertensive for renal failure
ACE inhibitors and ARBs; reduce risk for major CV events
41
New cards
vit D analogues for renal failure (FYI)
used to manage secondary hyperPTH
42
New cards
diuretics in renal failure
treat edema; lower tendenct to develoop hyperkalemia; decrease blood pressure
43
New cards
potassium sparing diuretics in renal failure
should be used cautiously, hyperkalemia associated with heart failure
44
New cards
renal failure and epoeitin
often have impraied EPO levels and anemia; need treatment
45
New cards
hyperphosphatemia
increased blood phosphate levels
46
New cards
chronic kidney disease hyperphosphatemia
hallmark, big risk of CV disease
47
New cards
hyperkalemia
high blood potassium levels; more severe than phosphatemia
48
New cards
medications inducing hyperkalemia
K+ sparing diuretics, NSAIDs, ACE inhibitors
49
New cards
phosphate binding agents
prevent absorption by forming insoluble complexes in GI tract
50
New cards
aluminum hydroxide
bind phosphate in GI
51
New cards
aluminum hydroxide adverse effects
increase Al levels in dialysis patients (toxic)
52
New cards
calcium carbonate
binds phosphate in GI tract
53
New cards
calcium carbonate effects
increase calcium levels: helps hypocalcemia in CKD but may cause calcification
54
New cards
sevelamer hydrochloride
non calcium based phosphate binder; anion exhcange resin
55
New cards
sevelamer hydrochloride effects
less likely to lead to tissue calcification, lowers LDL cholestrol, GI disturbances, affects fat soluble vitamin absorption, dont use in hypophsophatemia or bowel obstruction
56
New cards
how to treat hyperkalemia
cation exchange resin to bind potassium in colon
57
New cards
sodium or calcium polystyrene sulfonate
binds K in colon in exhcange for Na or Ca
58
New cards
sodium or calcium polystyrene sulfonate and sorbitol effects
increased risk for GI, bleeding, ischemic cholitis, perfroation, constipation
59
New cards
glucose + insulin mechanism
insulin activates Na/K ATPase to move K into cells
60
