Try these sample questions to review concepts for the OMSB Obstetrics and Gynecology (OEOG) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A 32-year-old nulligravida presents with severe secondary dysmenorrhea, deep dyspareunia, and chronic non-cyclical pelvic pain not relieved by NSAIDs and cyclical combined oral contraceptives. Transvaginal ultrasound demonstrates bilateral homogeneous, ground-glass ovarian cysts measuring 3.5 cm on the right and 3.0 cm on the left. She does not desire immediate conception. What is the most appropriate next step in medical management?
A.High-dose continuous estrogen monotherapy
B.Immediate exploratory laparotomy with bilateral oophorectomy
C.Dienogest (continuous progestin) or GnRH analog with add-back
D.Insertion of a copper intrauterine device for cycle control
Explanation: When combined oral contraceptives and NSAIDs fail in suspected or confirmed endometriosis with ovarian endometriomas, second-line medical therapy with continuous progestins (such as dienogest or oral norethindrone) or a GnRH agonist/antagonist with add-back therapy is recommended. These agents suppress ovarian follicular development and induce decidualization and atrophy of ectopic endometrial tissue. Surgery is reserved for medical failures, diagnostic uncertainty, large endometriomas (>4-5 cm), or obstruction.
2A 28-year-old woman presents to the emergency department with mild lower abdominal cramping, 6 weeks of amenorrhea, and light vaginal spotting. Her vital signs are: BP 120/75 mmHg, HR 74 bpm. Serum beta-hCG is 2,200 mIU/mL. Transvaginal ultrasound reveals an empty uterine cavity, an endometrial thickness of 12 mm, and an unruptured right adnexal mass measuring 2.4 cm with no fetal cardiac activity and no free fluid in the pouch of Douglas. Baseline liver enzymes, renal function, and complete blood count are normal. What is the most appropriate initial management?
A.Single-dose IM methotrexate with serial beta-hCG monitoring
B.Immediate exploratory laparotomy and right salpingo-oophorectomy
C.Uterine curettage followed by oral misoprostol
D.Expectant management with repeat ultrasound in 4 weeks
Explanation: Medical management with intramuscular methotrexate is the treatment of choice for hemodynamically stable ectopic pregnancy meeting standard criteria: unruptured adnexal mass <3.5 cm, serum beta-hCG <5,000 mIU/mL, absence of fetal cardiac activity, and normal baseline renal and liver function. Serum beta-hCG should be monitored on day 4 and day 7 post-injection, aiming for a >15% decline between days 4 and 7.
3Under the FIGO PALM-COEIN classification system for abnormal uterine bleeding (AUB) in non-gravid reproductive-age women, which of the following etiologies is categorized under the structural ('PALM') group?
A.Ovulatory dysfunction
B.Coagulopathy
C.Iatrogenic causes
D.Adenomyosis
Explanation: The FIGO classification divides abnormal uterine bleeding into structural causes ('PALM': Polyp, Adenomyosis, Leiomyoma, Malignancy and hyperplasia) and non-structural causes ('COEIN': Coagulopathy, Ovulatory dysfunction, Endometrial, Iatrogenic, Not otherwise classified). Adenomyosis is a structural disorder characterized by ectopic endometrial glands and stroma within the myometrium.
4A 44-year-old multiparous woman presents with progressively worsening menorrhagia and severe dysmenorrhea. Bimanual examination reveals a uniformly enlarged, tender, globular uterus of 12 weeks' gestational size. Transvaginal ultrasound demonstrates asymmetric anterior-posterior myometrial wall thickening, subendometrial myometrial cysts, and linear striations with loss of a distinct endomyometrial junction. What is the most likely diagnosis?
A.Endometrial polyp
B.Adenomyosis
C.Endometrial stromal sarcoma
D.Cervical stenosis
Explanation: Adenomyosis is characterized by benign invasion of endometrial basal glands and stroma deep into the myometrium, accompanied by reactive myometrial smooth muscle hyperplasia. Characteristic clinical features include an enlarged, globular, tender uterus ('boggy' uterus) in multiparous women in their 40s. Sonographic hallmarks include asymmetric myometrial thickening, intramyometrial cystic spaces, heterogeneous myometrial echo texture, and an indistinct junctional zone.
5A 35-year-old nulliparous woman presents with heavy menstrual bleeding resulting in microcytic anemia. Saline infusion sonohysterography (SIS) and pelvic MRI identify a single 3.5-cm intracavitary leiomyoma that is pedunculated and completely within the uterine cavity (FIGO Type 0 submucosal leiomyoma). She strongly desires to conceive within the next year. What is the surgical treatment of choice?
A.Open transabdominal myomectomy via laparotomy
B.Uterine artery embolization
C.Hysteroscopic myomectomy
D.Laparoscopic subtotal hysterectomy
Explanation: Hysteroscopic myomectomy is the minimally invasive gold standard for FIGO Type 0 (completely intracavitary/pedunculated) and Type 1 (<50% intramural extension) submucosal leiomyomas under 4-5 cm in women wishing to preserve fertility. It avoids transabdominal incisions, reduces recovery time, preserves the myometrial wall, and optimizes endometrial receptivity for future pregnancy.
6A 24-year-old woman presents to an outpatient clinic with lower abdominal pain, fever (38.4°C), and mucopurulent endocervical discharge. Bimanual pelvic examination elicits marked cervical motion tenderness and bilateral adnexal tenderness, without signs of peritonitis or tubo-ovarian abscess. Pregnancy test is negative. Which outpatient antibiotic regimen is recommended by the CDC STI Treatment Guidelines (2021)?
A.Ceftriaxone 500 mg IM once, plus doxycycline and metronidazole for 14 days
B.Oral Ciprofloxacin 500 mg single dose plus oral Azithromycin 1 g single dose
C.Oral Amoxicillin-clavulanate 1 g twice daily for 7 days as monotherapy
D.Intramuscular Gentamicin single dose plus oral Clindamycin 300 mg for 5 days
Explanation: Outpatient treatment for mild-to-moderate pelvic inflammatory disease (PID) requires broad-spectrum coverage against Neisseria gonorrhoeae, Chlamydia trachomatis, and anaerobes: Ceftriaxone 500 mg IM in a single dose (1 g if weight >=150 kg) combined with oral Doxycycline 100 mg twice daily for 14 days, plus oral Metronidazole 500 mg twice daily for 14 days to treat anaerobes, Trichomonas vaginalis, and associated bacterial vaginosis.
7A 23-year-old asymptomatic woman undergoes pelvic ultrasonography for irregular spotting. The scan incidentally reveals a 3.8-cm unilocular, thin-walled, purely anechoic cyst in the right ovary with acoustic enhancement, no internal echoes, no septations, and no Doppler vascular flow within the cyst wall. What is the most appropriate management plan?
A.Immediate laparoscopic cystectomy to rule out neoplasia
B.Reassurance; no surgery or routine follow-up imaging needed
C.Serum CA-125 measurement followed by urgent pelvic MRI
D.Transvaginal fine-needle aspiration of the cyst fluid
Explanation: In asymptomatic premenopausal women, a simple (unilocular, thin-walled, anechoic, avascular) ovarian cyst is almost always a benign functional cyst, such as a follicular cyst, that resolves on its own. Under O-RADS US v2022 (ACR), a simple cyst of more than 3 cm and up to 5 cm in a premenopausal woman is O-RADS 2 (almost certainly benign) and needs no follow-up imaging; follow-up ultrasound (at 12 months) is suggested only for simple cysts larger than 5 cm and smaller than 10 cm. Surgery, tumor markers and needle aspiration are not indicated. Earlier practice often repeated the scan after 8-12 weeks, which remains reasonable if symptoms develop.
8A 38-year-old woman presents with intermenstrual bleeding and prolonged menses. Saline infusion sonohysterography (SIS) demonstrates a well-circumscribed, echogenic intracavitary mass arising from the fundus with a distinct vascular pedicle visualized on color Doppler interrogation. The surrounding endometrium is thin and regular. What is the most likely diagnosis?
A.Intramural leiomyoma
B.Endometrioma
C.Serous cystadenoma
D.Endometrial polyp
Explanation: Endometrial polyps are hyperplastic overgrowths of endometrial glands and stroma around a central vascular core that project into the uterine cavity. On saline infusion sonohysterography (SIS), polyps typically appear as echogenic, polypoid intracavitary masses with a single feeding vascular pedicle on color Doppler, contrasting with submucosal fibroids that display circular rim vascularity and attenuation.
9A 26-year-old woman at 10 weeks of gestation presents with sudden-onset, severe right lower quadrant pain, nausea, and vomiting. Transvaginal Doppler ultrasonography demonstrates an enlarged 7-cm right ovary with peripherally displaced follicles and absent arterial and venous vascular flow. Emergency laparoscopy reveals a bluish-black, edematous, twisted right adnexa (adnexal torsion). What is the primary surgical recommendation?
A.Adnexal detorsion and ovarian preservation regardless of its dark ischemic appearance
B.Immediate right salpingo-oophorectomy without untwisting to prevent pulmonary embolism
C.Bilateral salpingo-oophorectomy to prevent contralateral recurrence
D.Simple puncture and needle decompression without detorsion
Explanation: Modern surgical consensus mandates adnexal detorsion and ovarian preservation in reproductive-age women, even if the ovary appears dusky, blue-black, or ischemic. Extensive evidence demonstrates that >90% of twisted ovaries regain endocrine and follicular function, and the historical fear of thromboembolism from detorsion is unfounded. Oophorectomy is indicated only if the tissue is frank necrotic gangrene with complete structural disintegration.
10A 29-year-old woman presents with severe vulvar throbbing pain, difficulty walking, and painful sitting for two days. Examination demonstrates a warm, intensely tender, fluctuant 4-cm cystic mass at the 4 o'clock position of the posterior vestibule with surrounding labial edema. What is the definitive initial clinical management?
A.Needle aspiration of purulent fluid under local anesthesia
B.Total surgical excision of the gland in the outpatient clinic
C.Incision and drainage with insertion of a Word catheter for 4 to 6 weeks
D.Oral cephalexin and warm sitz baths without procedural intervention
Explanation: A Bartholin gland abscess presents as a fluctuant, tender mass in the posterolateral introitus (4 or 8 o'clock position). The gold standard treatment is incision and drainage followed by placement of a Word catheter (or marsupialization). The catheter bulb is inflated with 2-3 mL of sterile saline and retained for 4-6 weeks to allow epithelialization of a new tract, preventing recurrence.
