A patient with gout has been instructed on the prescribed medication allopurinol (Zyloprim). Which patient statement indicates understanding of the action of this medication?
It increases formation of purines.
It blocks formation of uric acid.
It increases metabolism of purines.
It excretes proteins.
The Correct Answer is B
A. It increases formation of purines: This is incorrect. Allopurinol works by inhibiting the enzyme xanthine oxidase, which is involved in the conversion of purines to uric acid. Therefore, it reduces, rather than increases, uric acid formation.
B. It blocks formation of uric acid: This is correct. Allopurinol decreases uric acid production by inhibiting the enzyme xanthine oxidase, which converts xanthine to uric acid, thus helping to prevent gout attacks and manage chronic gout.
C. It increases metabolism of purines: Allopurinol does not increase the metabolism of purines. Instead, it reduces the conversion of purines to uric acid, which is the substance that accumulates and causes gout.
D. It excretes proteins: Allopurinol does not facilitate the excretion of proteins. Its primary action is to reduce the production of uric acid.

C. Pain: Pain is a hallmark symptom of arterial occlusion, often described as severe and sudden, due to tissue ischemia.
D. Pallor: Affected limbs or areas may appear pale (pallor) because of reduced blood flow.
E. Palpitations: Palpitations are not a direct symptom of arterial occlusion. They are more related to cardiac conditions.
