NAPLEX (North American Pharmacist Licensure Examination) Practice Exam

Question: 1 / 1820

What pH level is consistent with bacterial vaginosis or trichomoniasis infection?

Less than 4.5

pH 4.5

Greater than 4.5

Bacterial vaginosis and trichomoniasis are two common vaginal infections. An elevated vaginal pH level is consistent with both infections. Normal vaginal pH is typically acidic, around 3.8 to 4.5. However, in the case of bacterial vaginosis or trichomoniasis, the pH is often greater than 4.5 due to the overgrowth of the infecting bacteria or parasites, leading to an alkaline environment. Therefore, a vaginal pH greater than 4.5 is indicative of bacterial vaginosis or trichomoniasis infection.
