Final answer:
A patient with grey malodorous vaginal discharge and pH over 5.0, showing anaerobic coccobacilli on wet prep, is likely diagnosed with bacterial vaginosis; treatment usually includes antibiotics.
Step-by-step explanation:
The patient presenting with thin, grey malodorous vaginal discharge and a pH > 5.0, with saline wet prep showing vaginal squamous epithelial cells coated with anaerobic gram-variable coccobacilli is likely suffering from bacterial vaginosis (BV). This diagnosis is supported by the abnormal vaginal pH level, characteristic discharge, and presence of clue cells on the wet prep. The absence of lactobacilli and presence of gram-variable coccobacilli further point towards BV. Treatment typically involves antibiotic medication, with metronidazole or clindamycin being commonly prescribed.
