Q

Why is there a drop in HCO3 in metabolic acidosis

A

drop in bicarb is because its eating up/buffering/used in attempt to balance the acid

Q

Metabolic alkalosis is divided into

A

volume/nonvolume responsive.

non volume = malignancy

volume/chloride responsive= volume responsive mean fluid response will shut down physiologic response and restore pH. treatment = NaCl-, chloride will attach to Hco3
