Renal Flashcards
Chronic NSAID use increases risk for?
tubulointerstitial nephritis and papillary necrosis
Fluid management for hypovolemic hypernatremia w/ syx
NS until euvolemic
Then add 5% dextrose
Tx for urge incontinence
1st line - pelvic floor exercises
Non responders - add po oxybutynin
Why is it difficult to correct hypokalemia in some alcoholics?
If they also have hypomagnesemia - removes inhibition of renal K+ excretion
Why does nephritic syndrome cause pulmonary edema?
Decreased GFR -> retention of Na+ and water by the kidneys
Get crazy high HTN
Gross hematuria with blood and protein in the sediment, no specific syx, comes from?
Glomerular damage
What is amiloride?
K+ sparing diuretic
Consider switching in pts with hyperkalemia
why do diuretics cause AKI?
Reduced CO -> prerenal ARI
DM pt has nocturia and 3+ protein in dipstic. Wy?
Diabetic micrangiopathy
Moderate proteinuria and CKD with elevated Cr
Dietary recommendation to prevent calcium oxalate renal stones
- Increased fluid intake
- Decreased sodium intake
- Normal dietary calcium intake
- Thiazide diuretics
- Low protein diet
While on nitroprusside drip pt develops HA, confusion, arrhythmia, flushing, respiratory depression. why?
Cyanide toxicity
Risk is increased when pt has CKD
How do you tx nephrogenic DI d/t Lithium?
Salt restriction
d/c lithium
Girl has anorexic patterns but presents with orthostatic hypotension, hyponatremia, hypokalemia. But, her urinary Na and K are elevated. Why?
Diuretic abuse
When would you do urgent dialysis?
AEIOU
Acidosis (pH<7.1)
Electrolyte abn - EKG changes or K+> 6.5
Ingestion - methanol, salicylate, lithium
Overload - volume overload refractory to diuretics
Uremia - if syx (encephalopathy, pericarditis, bleeding)
Best initial tx for renal a. stenosis
ACEI or ARB
Consider stenting or revascularization if resistant to medical mangment
