A client taking nitrofurantoin for a urinary tract infection is concerned about brown-colored urine. What should the nurse advise?

When advising a client taking nitrofurantoin for a urinary tract infection, it's important to recognize that one of the common side effects of this medication is the discoloration of urine, which can appear brown. This occurs due to the way the body metabolizes nitrofurantoin, and it is considered a harmless effect of the medication. Therefore, reassuring the client that this side effect is expected and not harmful helps alleviate their concerns while ensuring they continue their treatment as prescribed.

Encouraging the client to continue taking the medication as directed ensures that the urinary tract infection is adequately treated, preventing potential complications. This information is crucial for the client to understand that the change in urine color is a normal response and does not indicate a need to stop the medication or seek immediate medical attention unless other concerning symptoms arise.

Many other choices may imply unnecessary actions, creating confusion or anxiety for the client, which is why providing clear and comforting information about the side effect is beneficial.
