Answer to Question 1

ANS: C
Sodium citrate is an alkalinizing drug that would worsen a state of metabolic alkalosis.

Answer to Question 2

ANS: B
Acetazolamide, a carbonic anhydrase inhibitor, raises urinary pH by increasing the urinary loss of HCO3- but paradoxically lowers blood pH by promoting the elimination of Na+, K+, bicarbonate, and H2O.
