Podocyte loss of foot processes
3 medications that can be used in nephrotic syndrome
ACE Arbs
Statins
Neprhtitic syndrome casts
RBC casts = PSGN
Nephrotic syndrome or nephritic syndrome produces more protein
Nephrotic does more than 3.5 g / day with EDEMA
3 type of AKI
Pre
Intra
Post
“Kidney”
BPH can cause what type of AKI
Post
Watery diarrhea can cause waht type of AKI
Pre renal AKI
BUN to creatine what should the ratio be
Greater than 20:1 = PRE RENAL
Less than 20:1 = INTRINSIC
MC type of AKI
ATN = tubular necrosis
3 pre renal AKI causes
Cardio shock
Hemmorhage
Sepsis
Decreased perfusion ; think before the kidney; blood flow problem
Renal AKI causes
Toxins
Drugs

3 type of post renal AKI
Enlarged prostate
Kidney stone
Tumors
Obstructive issues
3 type of diseases that can cause glomerulonephritis to know
Lupus
Anti GBM
Henoch Schlenoch Purpura
Metallic tase in mouth think what
If malaise and decreased urine output = general
Creatinine increase of what = AKI
Greater than 50 % increase from baseline
Low FE of NA+ suggests an AKI where
Pre Renal affecting the kidney
Best image for obstruction or hydronephrosis
Kidney U/S
ATN casts =
Muddy brown casts
Indications for dialysis AEIOU
Acidosis
Electrolytes = remove high K+
Ingestions
Overload
Uremia = pericarditis , encephalopathy
MC cause of CKD
Diabetes ; CKD dx = longer 3 months
CKD findings common 4
Uremia
Anemia
HyperK
Fluid retention
Casts assoc with CKD
Broad waxy casts
Mutation of what kind can cause PCKdz
PCKD1 and PCKD2
PCKDz has what kind of presentation
Palpable kidney
Get renal U/S ; see huge cystssss
3 management for PCKDz
Increase fluid
Hydration
Restrict Sodium
Vasopressin blockers = tolvaptan
ACE or ARB if with HTN
Dialysis / Transplant if ERDz
Worst complication of PCKdz
Cerebral aneurysm ; happens 5-10% of the time
Heart valve disorder associated with PCKDz
Mitral valve prolapse
metabolic alkalosis is usually if a person is
Vomiting !
Metabolic acidosis 3 common findings
Kussmauls = breathe off CO2
Headache lightheadedness
Decreased muscle reflexes
Metabolic alkalosis 3 common findings
Twitching or spasms
Increased reflexes
Bradypnea
Low bicarbonate = less than what
24
Low PCo2 = less than what
40
PCO2 less than what is considered respiratory alkalosis [compensatory]
35
PCo2 greater than what is considered respiratory acidosis [compensatory]
45
Bicard greater than what Causes bicarbonate to drive the alkalosis
Greater than 28
Anion gap equation ; and what is considered elevated
Na+ - Cl- -HCO3 ;; greater than 12 = ELEVATED
With COPD commonly think what type of acid base issue
Respiratory acidosis
3 other causes of respiratory acidosis
CNS depression = opiates
Myasthenia Gravis
NMSK disorders = GB
Hyperventalation causes what
Respiratory alkalosis because you are losing CO2
3 common causes of respiratory alkalosis
Salicylate toxicity
Acute asthma attack
Pulmonary Embolism
Describe sxs of respiratory acidosis
Things go DOWN
Coma
Death
PCO2 necassary for respiratory acidosis =
Greater than 45 and acidic
PCO2 necassary for respiratory alkalosis
Less than 35 and alkalotic
Bicarbonate for metabolic alkalosis [compensatory]
Greater than 29
Bicarbonate for metabolic acidosis [compensatory]
Less than 22
what is the acronym for acid base disorders as a rule
ROME
PCo2 normal = 40
Bicarbonate normal = 25
Physio pH = 7.4
With PCO2 think what compensation and same for HCO3 ?
PCO2 = Lungs
HCO3 = Kidney
Intracatbale vomiting can cause what
Low potassium
Metabolic alkalosis
Tumor lysis syndrome usually does what
Lysis cells which means K+ goes up
3 potassium intracellular shifting agents / states
Insulin
Albuterol
Alkalosis
Renal over excretion of potassium ; 3 reasons?
Thiazides
HypoMagnesium
Hyperaldosteronism
3 manifestation of Hypokalemia
Cramps
Delirium
Tetany
Potassium is low if less than
3.5
When do you give IV K+ instead of PO
Less than 3 usually and dont forget Mg
Hyperkalemia cell stabilizing medication
Calcium gluconate
3 common reasons for Hyperkalemia
Burns
Drugs = ACE , DIgoxin , K+ Diuretics
Addisons Disease
High K+ is usually as high as
Greater than 5.2
What type of overdose can cause hyperkalemia sine wave
TCA overdose
Insulin
Albuterol
Bicarbonate
How do they affect K+
Insulin = shifts potassium into the cell
Albuterol = upregulates cAMP and shifts K+ into cell s
Bicarbonate = shifts potassium into the cell
Furosemide causes what for hyperK+
Renal excretion of K+
Neuro complication of rapid low sodium correction
Osmotic demyelination syndrome
Urine Na+ low makes you think a what cause low ECF volume think
-vomiting
-diarrhea

[before the kidney] metabolic
Urine Na+ high with low ECF volume ; think a what cause
-Addisons disease
-CKD
Kidney [intrrenal]
SIADH is a what volume status disease
