About vaginal discharge: 1. Normal vaginal pH in the reproductive years is about 3.8-4.5. 2. In vulvovaginal candidiasis the pH is usually above 4.5. 3. Clue cells are epithelial cells coated with coccobacilli. 4. A positive whiff test occurs in bacterial vaginosis and often in trichomoniasis. Which statements are correct?
- A1, 3 and 4 only
- B2 and 4 only
- C1, 2, 3 and 4
- D1, 2 and 3 only

Answer: A · 1, 3 and 4 only
Lactobacilli keep the normal vaginal pH acidic, at about 3.8-4.5. Candidiasis usually leaves the pH normal (under 4.5), while bacterial vaginosis and trichomoniasis raise it above 4.5; both may release amines and give a fishy odour with KOH. Clue cells are the hallmark of BV.
- B: Statement 2 is wrong, and statements 1 and 3 are correct.
- C: Statement 2 is wrong, so not all four are correct.
- D: Statement 2 is wrong; the pH stays normal in candidiasis.
Remember this
Candidiasis keeps a normal acidic pH; BV and trichomoniasis raise it above 4.5.
