Acid Base Flashcards
1
Q
Anion gap calculation
A
Anion gap = (Na + K) - (Cl + HCO3)
2
Q
What does cause acidosis without increased anion gap?
A
Respiratory or hyperchloremia (high Cl)
Examples: RTA (failure of bicarb buffer system), diarrhea (loss of intestinal bicarb)
3
Q
Five causes of increased anion gap
A
ketosis, lactic acidosis, acetaminophen toxicity, EG toxicity, renal failure
4
Q
Four causes of metabolic acidosis with NORMAL anion gap
A
diarrhea, vomiting, RTA, Addison’s
5
Q
What does cause acidosis with increased anion gap?
A
salicylates, ethylene glycol, lactic acidosis, CKD, DKA (caused by gain of acid)
