Q

Initial treatment for severe hyperkalemia

21
Q

Hyperkalemia

- MCC

Study These Flashcards
A

decreased excretion

22
Q

Hyperkalemia

- RF

Study These Flashcards
A
  • renal impairment
  • DM
  • K-sparking diuretics, NSAIDs, ACE
23
Q

Hyperkalemia

- causes

Study These Flashcards
A
  • RF
  • increased intake
  • shift from intracellular to extracellular
24
Q

Hyperkalemia

- clinical

Study These Flashcards
A
  • mostly asx
  • ## sx related to cardiac and msk function, mc fatigue and weakness
25
Hyperkalemia | - treatment
- Calcium** - insulin with dextrose, albuterol, bicarb - furosemide or dialysis
26
Acute interstitial nephritis | - MCC
- meds (NSAIS, PCN, PPI) | - infection
27
Acute interstitial nephritis | - overview
causes AKI dt immune-mediated tubulointerstitial injury
28
Acute interstitial nephritis | - dx
- eosinophiluria in pt with AKI (indicates allergic reaction)
29
Polycystic Kidney Disease | - overview
- autosomal dominant | - 50% ESRD by age 60
30
Polycystic Kidney Disease | - dx
- 30-59 with 2+ cysts on US or CT bilaterally highly likely | - genetic testing to confirm
31
Polycystic Kidney Disease | - clinical
- abdominal / flank pain - hx hematuria - renal infection - nephrolithiasis - HTN
32
Polycystic Kidney Disease | - other risks
- cerebral aneurysm - MV prolapse - Aortic aneurysm - Aortic valve abnl - colonic diveticula
33
Polycystic Kidney Disease | - mgmt
- no cure - aggressive HTN mgmt with ACE/ARB - low-protein diet - pain control, infection control - dialysis or transplant
34
Renal artery stenosis | - dx
- intimal: CTA or renal angiography | - gadolinium-enhanced MRA if decreased renal fn
35
Renal artery stenosis | - mgmt
- ACE/ARB | - revascularization
36
Anion gap calculation
Na - (Cl + bicarb) | nl: 3-11
37
Anion gap metabolic acidosis
MUDPILES - methanol - uremia - DKA - paraldehyde - Iron, Isoniazid - Lactic acidosis - Ethylene glycol - Salicylates
38
What other electrolyte disorder is associated with hypokalemia
hypomagnesemia
39
Hyponatremia | - pt with neuro sx = what treatment
- hypertonic saline (3%) 100 ml bolus over 10 min
40
Acute tubular necrosis (ATN) | - leads to what
#1 cause of AKI
41
Acute tubular necrosis (ATN) | - caused by what
decreased blood flow to kidney, usu 2/2 drop in blood pressure = renal tubule ischemia = necrosis
42
Acute tubular necrosis (ATN) | - Urine microcopy
- muddy brown cellular casts - fine gradual casts - renal tubular epithelial cells
43
Acute tubular necrosis (ATN) | - labs
- BUN/Cr < 20 - FeNa >2% * * both indicate renal injury
44
Acute tubular necrosis (ATN) | - MC meds that cause
- NSAIDs | - ACE / ARB
