Could you be more specific of the case of acidosis? I understand that our bodies are meant to be alkaline and you can be in acidosis by your pH being more acidic than it is normally. Our bodies pH is between 7.35 and 7.45. The closer is gets to 7.00, then the more acidic it is. Even if it is still a base. Your "teacher" is making no sense. After all, the safe displatia of pH is only within a one tenth range. That said, it doesn't take much to throw your body off and really screw you up IE: acidosis. Is there anything wrong with the patients flow of Phosphate and protiens? Also check respiratory changes as hyperventilation is the bodies natural way of trying to change it's pH to be more basic. In that you'll have OH- (I don't know how to make that a superscript, but it's negative) + CO2 (subscript that) ---> HCO3- (subscript the 3, superscript the negative). It can also produce some changes necessary to alter the level of PaCO2. I mean, of course this all is case by case. If it's renal, urinary, alcohol induced or anything along those lines. Either way, your teacher is a jackass. Ignore it though, no sense in stirring shit when you're liable to be pushed in the pot.
