Final answer:
Treatment with either oral metronidazole or tinidazole is recommended for a female diagnosed with Trichomonas, and treating the sexual partner at the same time is crucial to prevent re-infection.
Step-by-step explanation:
The most appropriate management for a 32-year-old female who has been diagnosed with Trichomonas via nucleic acid amplification testing (NAAT) is treatment with either oral metronidazole or tinidazole. It is important to treat sexual partners simultaneously to avoid re-infection, and to abstain from intercourse for at least one week until both partners have completed their course of treatment and follow-up. NAAT is preferred over other diagnostic methods such as wet mounts due to its higher sensitivity for detecting Trichomonas vaginalis.
