Correct Answer is B

Explanation

Choice A rationale
Drinking more fluid can help dilute the urine but will not prevent it from becoming brown due to the medication.
Choice B rationale
Brown-colored urine is a known harmless side effect of nitrofurantoin. It is due to the medication itself and does not indicate any harm or need for a change in treatment.
Choice C rationale
Changing the medication is not necessary unless there are other signs that the infection is not resolving. Brown-colored urine alone is not an indication of treatment failure.
Choice D rationale
An increase in RBC destruction can cause brown urine, but this is not the case with nitrofurantoin. The brown color is due to the medication and not due to RBC destruction.

A. Lethargy. B. Reddish-orange urine. C. Burning during urination. D. Visual disturbances.

Correct Answer is B

Explanation

Choice A rationale
Lethargy is not a common side effect of phenazopyridine. This medication is primarily used to relieve urinary tract pain and discomfort.
Choice B rationale
Reddish-orange urine is a common and expected side effect of phenazopyridine. This discoloration is harmless but can stain clothing.
Choice C rationale
Burning during urination is a symptom that phenazopyridine is used to relieve, not a side effect of the medication.
Choice D rationale
Visual disturbances are not commonly associated with phenazopyridine use.
