Answer: (B)

The recommended dosing of Bactrim, which is a combination of trimethoprim and sulfamethoxazole, for the treatment of uncomplicated urinary tract infections (UTIs) is commonly 160 mg of trimethoprim and 800 mg of sulfamethoxazole taken orally every 12 hours. This dosage ensures effective antimicrobial activity while minimizing the potential for side effects and resistance associated with higher doses. This dosing regimen helps maintain adequate serum levels of the medication to effectively target the bacteria typically responsible for UTIs, making it an appropriate choice in clinical practice.
