here is the 5th sentence on page 123 in my Pathophysiology book, which just so happened to be the closest book to me at the time I read Emily's post.

"When acid loss is caused by vomiting, renal compensation is not very effective because loss of chloride (an anion) in hydrogen chloride (HCL) acid stimulates renal retention of bicarbonate. Hyperaldoseteronism also can lead to alkalosis as a result of sodium bicarbonate retention and loss of hydrogen and potassium."

I know I officially need to get a life! Anyway, I think Betsy's was the best. I am laughing at that one.
