A Child Ingests a Parent's Aspirin Tablets, and the Prescriber

A child ingests a parent's aspirin tablets, and the prescriber orders sodium bicarbonate to block the toxic effects of the aspirin. The nurse caring for this patient knows that sodium bicarbonate is effective against the aspirin because it:

A) accelerates its passage through the intestine.
B) alters urinary pH to enhance renal excretion.
C) induces CYP isozymes to increase drug metabolism.
D) raises the pH of the interstitial fluid to facilitate passage out of the cells.
