Final answer:
The medication that can be used to help pass a kidney stone is Tamsulosin. Acetaminophen and Ibuprofen can be used to manage the pain associated with kidney stones. Oxybutynin is not typically used for passing kidney stones.
Step-by-step explanation:
The medication that can be used to help pass a kidney stone is Tamsulosin (option a). Tamsulosin is an alpha-blocker that helps relax muscles in the urinary tract, including the muscles in the ureter, which can facilitate the passage of the stone.
Acetaminophen (option b) and Ibuprofen (option c) are pain medications that can be used to manage the pain associated with kidney stones, but they do not directly aid in passing the stone. Oxybutynin (option d) is a medication used to treat overactive bladder and is not typically used for passing kidney stones.
