Explanation - Untreated chlamydial infections can ascend to cause PID, leading to tubal damage and infertility.
Correct answer is: Infertility

Q.8 Which laboratory test is most sensitive for detecting Chlamydia trachomatis infection?

Gram stain
Culture on blood agar
Wet mount
Explanation - NAAT is highly sensitive and specific for detecting Chlamydia trachomatis in cervical or urine samples.
Correct answer is: Nucleic acid amplification test (NAAT)

Q.9 Bacterial vaginosis is associated with an increased risk of which pregnancy complication?

Preterm labor
Gestational diabetes
Preeclampsia
Hyperemesis gravidarum
Explanation - Bacterial vaginosis can disrupt vaginal flora and has been linked to preterm labor and low birth weight.
Correct answer is: Preterm labor

Q.10 Which of the following infections is typically associated with a thick, white, cottage cheese-like vaginal discharge?

Candidiasis
Trichomoniasis
Bacterial vaginosis
Gonorrhea
Explanation - Vulvovaginal candidiasis often produces a thick, white, curd-like discharge along with pruritus.
Correct answer is: Candidiasis

Q.11 A patient presents with fever, lower abdominal pain, and purulent cervical discharge. Which empiric therapy is most appropriate for PID?

Ceftriaxone plus doxycycline
Fluconazole
Metronidazole only
Amoxicillin
Explanation - Empiric treatment for PID typically covers gonorrhea and chlamydia using ceftriaxone plus doxycycline, sometimes with metronidazole if anaerobic coverage is needed.
Correct answer is: Ceftriaxone plus doxycycline

Q.12 Which sexually transmitted infection is most strongly associated with cervical cancer?

Human papillomavirus (HPV)
Chlamydia trachomatis
Trichomonas vaginalis
Neisseria gonorrhoeae
Explanation - Persistent infection with high-risk HPV strains (e.g., 16 and 18) is the primary cause of cervical cancer.
Correct answer is: Human papillomavirus (HPV)

Q.13 Which condition is characterized by an elevated vaginal pH >4.5?

Bacterial vaginosis
Candidiasis
Trichomoniasis
Herpes simplex infection
Explanation - Bacterial vaginosis causes a shift in vaginal flora, raising the vaginal pH above 4.5.
Correct answer is: Bacterial vaginosis

Q.14 Which infection may present with vesicular lesions on the vulva and inguinal lymphadenopathy?

Herpes simplex virus
Candidiasis
Bacterial vaginosis
Trichomoniasis
Explanation - Genital herpes, caused by HSV-1 or HSV-2, typically presents with painful vesicular lesions and regional lymphadenopathy.
Correct answer is: Herpes simplex virus

Q.15 The 'whiff test' is used to help diagnose which gynecologic infection?

Bacterial vaginosis
Candidiasis
Trichomoniasis
Gonorrhea
Explanation - The whiff test involves adding KOH to vaginal discharge; a fishy odor suggests bacterial vaginosis.
Correct answer is: Bacterial vaginosis

Q.16 Which sexually transmitted infection is most likely to be asymptomatic in women but can cause urethritis and infertility?

Chlamydia trachomatis
Trichomonas vaginalis
Neisseria gonorrhoeae
HSV
Explanation - Chlamydia is often silent in women but can ascend to cause PID and tubal factor infertility.
Correct answer is: Chlamydia trachomatis

Q.17 Which of the following infections is a protozoal infection of the female genital tract?
