Final answer:
The presence of a white curdlike vaginal discharge and an itchy perineum are indicative of a fungal vaginal infection caused by Candida albicans, commonly referred to as a yeast infection.
Step-by-step explanation:
Diagnosis of Fungal Vaginal Infection
During the pelvic examination of a 22-year-old woman, a white curdlike vaginal discharge was noted, suggesting a possible yeast infection. To support a diagnosis of a fungal vaginal infection, other assessments such as symptoms, microscopic examination, and pH level of the discharge are considered. Among the options given, B. An itchy perineum supports the diagnosis of a fungal infection caused by Candida albicans, commonly known as a yeast infection.
Fungal vaginal infections, or yeast infections, are characterized by a thick, white discharge similar to cottage cheese and symptoms like itching (pruritus) and discomfort. Other possible symptoms, like a foul odor or the presence of a forgotten tampon, are more commonly associated with bacterial infections or tampon-related issues, not fungal infections.
Yeast infections are treated with antifungal medications and are fairly common. Conditions like antibiotic use, diabetes, pregnancy, or a compromised immune system can disrupt the normal vaginal microbiota balance, leading to an overgrowth of Candida and the subsequent development of symptoms like itchy perineum.
