Flashcards in MKSAP - Nephrology Deck (19):
Proteinuria only when upright (children)
Persistent hematuria? Interpretation of urine? Tests
3+ RBCs in urine on 2 more samples
If casts/dysmorphic RBCs - glomerular origin
If normal RBCs - from lower in the urinary tract
Kidney US and cytoscopy
Risk factors for genitourinary malignancy?
3. tobacco use
4. cyclophosphamide/benzene/radiation exposure
Pt with azotemia - must do this before dialyzing?
Fluid resuscitation (and see if pt improves)
Drugs to help with hepatorenal syndrome?
Octreotide and midodrine
Drug to treat malignancy-related hyperuricemia?
In acute interstital nephritis - expect to see what UA findings?
pyuria, WBC casts, eosinophils on UA
On ACE/ARB - acceptable increase in Cr?
Gap-metabolic acidosis - next steps?
2) Delta-Delta (AG - 12 + bicarb)
Ammonium excretion in types of metabolic acidosis?
extra-renal - high acid secretion and high urine ammonium
renal acidosis - low acid secretion and low urine ammonium
Urine anion gap? Normal range? Interpretation?
Urine Na + Urine K - Urine Cl
Neg UAG - non-renal (NH4 excreted)
Positive UAG - renal cause
HyperK in pt with CKD - how to tell if its due to the CKD or other factor?
If GFR>15, due something else
Pt with CKD - when is a thiazide not effective?
Way to estimate osmolarity?
hyperosmolar Pt without hyperglycemia who presents with polyuria and polydipsia with dilute urine? Test and interpretation?
Give AVP - if urine concentrates, then central, if not nephrogenic
Binds to parathyroid Ca-sensing receptor decreasing PTH release
Pt with hyperCa and sarcoidosis - tx for hyperCa (and mech)?
Steroids (Ca from macrophages, steroids deactivate macrophages)
Hypophosphatemia seen in what types of pt? Precipitated by? Symptoms?
Alcoholics, glucose administration (pushes phosphate into cells)
Confusion, rhabdomyolysis, hemolytic anemia, severe muscle weakness
