Chronic renal failure Lecture Flashcards
Spectrum of disease with declining function/Decreased glomerular filtration rate
Resultant increase in nitrogenous waste products (azotemia)
Alteration in fluid an electrolytes
CKD
Currently is based on 3mo of disease and
eGFR of
CKD
2 most common causes today of CKD
diabetes
hypertension (nephrosclerosis)
Anorexia (Loss of appetite, Resultant weight loss) Nausea or vomiting Malaise Headache Itching
CKD symptoms
Decrease in Na+ transport which is a large source of energy/heat production leads to…..
Hyperthermia (seen in CKD)
“Pseudodiabetes”
Slower handling of glucose load due to insulin resistance
Impaired carb metabolism (in CKD)
what happens to triglyceride levels in CKD?
Increase
but normal cholesterol
potassium does what in CKD?
increases
sodium goes down
Decreased K+ excretion, typically if GFR
Seen in CKD
When GFR decreases below 10cc/min, ___ increases as aldosterone affect is blunted
K+
aldosterone antagonist that…
Promotes diuresis
K+ retention
Used to treat HTN and CHF
Spironolactone
Acidosis causes efflux of K+ from intracellular to extra cellular fluids
ACE inhibitors, Beta-blockers, Cyclosporine in transplant all can lead to as well
May lead to cardiac arrhythmias and even death
Impacts of Hyperkalemia
Sodium bicarbonate Loop diuretic Insulin Dextrose Fluids (dilutes the K+) Albuterol Sodium polystyrene-Ion exchange resin (PO or PR)-Kaexalate® Dialysis
Hyperkalemia tx
Hyperuricemia (increase gout)
Seen in renal failure
Which acid-base disorder is commonly seen in kidney disease?
Metabolic acidosis
calcium leeches out of bones, increasing risk fracture
seen in renal failure
