Gonorrhoea-which is not a presenting feature:a) Dischargeb) Acute febrile episodesc) Hematuriad) Reddened lips of vulva and vagina

**Core Concept**
Gonorrhoea is a sexually transmitted infection caused by the bacterium Neisseria gonorrhoeae. It primarily affects the mucous membranes of the reproductive tract, but can also involve other parts of the body such as the eyes and throat.

**Why the Correct Answer is Right**
The presenting features of gonorrhoea are typically related to the infection of the mucous membranes. Discharge, both purulent and mucopurulent, is a common symptom, especially in the cervix, urethra, and rectum. Acute febrile episodes can occur due to the body's inflammatory response to the infection. Hematuria, or blood in the urine, can occur if the infection ascends to the upper genitourinary tract. However, reddened lips of the vulva and vagina are not typically a presenting feature of gonorrhoea.

**Why Each Wrong Option is Incorrect**
* **Option A:** Discharge is a common presenting feature of gonorrhoea, especially in women with cervical or vaginal infections.
* **Option B:** Acute febrile episodes can occur in gonorrhoea due to the body's inflammatory response to the infection.
* **Option C:** Hematuria can occur in gonorrhoea if the infection ascends to the upper genitourinary tract.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that gonorrhoea can cause a range of symptoms, but discharge, especially from the cervix, urethra, or rectum, is a classic presenting feature.

**Correct Answer: D. Reddened lips of vulva and vagina**
