A client with a history of kidney stones is prescribed allopurinol. The nurse should recognize that this medication is primarily used to:
Increase urine output
Dissolve existing kidney stones
Reduce the formation of uric acid stones
Increase the excretion of calcium
The Correct Answer is C
A. Allopurinol does not directly increase urine output. It is not a diuretic and is not used for that purpose.
B. Allopurinol does not dissolve existing kidney stones. It is primarily used to prevent the formation of uric acid stones, not to treat existing stones.
C. This is the correct answer. Allopurinol is a medication used to reduce the production of uric acid in the body. By lowering uric acid levels, it can help prevent the formation of uric acid stones.
D. Allopurinol does not increase the excretion of calcium. It is used specifically to address uric acid levels and prevent uric acid stone formation.
