Which medications can be used to treat candidiasis?

The correct answer for treating candidiasis is the combination of Amphotericin B and Nystatin. Both of these medications are antifungals specifically effective against fungal infections, including those caused by Candida species. Amphotericin B is often used for more severe systemic infections and has broad-spectrum activity against various fungi. Nystatin is effective for topical and mucosal candidiasis, such as oral thrush and skin infections.

The other options consist of antibiotics or medications that do not possess the antifungal properties necessary for treating an infection caused by Candida. Oxacillin and Tobramycin are antibiotics that target bacterial infections, with no efficacy against fungal infections. Carbenicillin is another antibiotic, and combining it with Oxacillin does not provide any antifungal coverage. Thus, while Amphotericin B and Nystatin target the fungal infection directly, the other options do not address the treatment of candidiasis effectively.
