Final answer:
For a patient diagnosed with a yeast infection manifested as oversalivation and creamy lesions on the tongue, miconazole is an appropriate topical antifungal treatment. Other treatments may include nystatin, clotrimazole, fluconazole, or amphotericin B based on infection severity.
Step-by-step explanation:
When a patient comes to the clinic with symptoms of oversalvation and creamy, white lesions on the tongue, and a yeast infection is confirmed with KOH prep, the treatment plan should include antifungal medications. Given the choices listed, miconazole would be an appropriate treatment option. Miconazole is an azole antifungal that can be used topically and is effective against Candida infections, like oral thrush. Other effective treatments, depending on the severity of the infection, include nystatin, clotrimazole, fluconazole, itraconazole for resistant strains, or amphotericin B in severe cases.
