A female patient tells the nurse that she thinks she has a vaginal infection because she has noted inflammation of her vulva and the presence of a frothy, yellow-green discharge. The nurse recognizes that the clinical manifestations described are typical of what vaginal infection?
Correct Answer: A
Rationale: The clinical manifestations of inflammation of the vulva and the presence of frothy, yellow-green discharge are indicative of a vaginal infection caused by Trichomonas vaginalis. Trichomoniasis is a sexually transmitted infection caused by a protozoan parasite. It commonly presents with symptoms such as frothy, yellow-green vaginal discharge, vaginal itching, inflammation of the vulva, and sometimes a foul odor. Testing for Trichomonas vaginalis can be done through microscopic examination of the vaginal discharge or through nucleic acid amplification tests. Treatment usually involves the use of antibiotics such as metronidazole or tinidazole. It is important to promptly diagnose and treat trichomoniasis to prevent complications and further transmission.
