Q

Causes of calcium oxalate stones in malabsorption/diarrhea

A
  1. urne citrate is an inhibitor of crystallization that is reduced in metabolic acidosis
  2. enteric calcium binds to poorly absorbed fat allowing oxalate to be absorbed and excreted in the urine

can be rapid. 2-3mmol immediately

39
Q

Correction rate of chronic hyponatremia

A

<10 in 24 hours.

40
Q

imaging for new diagnosis of fibromuscular dysplasia

A

one time head to pelvic imaging to look for aneurysms.

41
Q

Serum Cr elevation of more than 30% after initiation of ACE

A

look for fibromuscular dysplasia

42
Q

When to test for primary aldosternonism

A
  1. resistant HTN, adrenal mass
  2. spontaneous hypokalemia
  3. diuretic induced hypokalemia
43
Q

Dialysis and statins

A

Recommends against, in patients with ESRD, unless they have residual function of kidneys

44
Q

Gold standard for nephrolithiasis

A

Non contrast, helical CT

45
Q

Management of primary membranous nephropathy

A

PLA2R highly specific
- high rates of remission in 6-12 months. statin (if applicable) plus ace/arb and monitor. if things change or persistent nephrotic protein start immunosuppressants

  1. After alternating months of steroids + alkylating agents (can use cyclosporine if can’t use alkylating ages)
46
Q

Distal type 1 RTA

A

hyperchlorema, hypoKalemia 2/2 inability to excrete acid

47
Q

type 4 RTA

A

distal hyperkalemic (2/2 aldosterone def or resistance), NAGMA

48
Q

type 2 (prox)

A

issue with bicarb reclaiming

49
Q

Needed in the Dx of HELLP

A

MAHA (peripheral smear and bili level)

50
Q

B2 micro globulin associated amyloid pts

A

seen in dialysis for at least 5 years, present with shoulder pain, carpal tunnel

51

resistant HTN

52
Q

How to evaluate metabolic alkalosis

A

urine Cl

53
Q

saline responsive metabolic alkalosis lab

A

urine cl <15

54
Q

management of hypermagnesemia

A

saline
lasix
IV calcium

55
Q

electrolyte issues 2/2 hypomag

A

hypoK

hypoCa (increased PTH increase)

56
Q
