Mama Teen Bean was pushing her chair in when it hit Papa Teen Bean's toe, he screamed really loud, and Mama laughed, she went to grab his medication, allopurinol (Zyloprim) out of the medicine cabinet. Why would she grab this medication for Papa Teen Bean?

A. It increases metabolism of purines: Rationale: Allopurinol does not increase metabolism of purines. It inhibits the enzyme responsible for converting purines to uric acid. B. It increases formation of purines: Rationale: Increasing purine formation would worsen gout by increasing uric acid. C. It excretes protein: Rationale: Allopurinol’s mechanism of action is unrelated to protein metabolism or excretion. D. It blocks formation of uric acid in patients with Gout: Rationale: Allopurinol inhibits xanthine oxidase, the enzyme that converts purines into uric acid, thereby reducing uric acid levels in gout.
