My first National Board of Medical Examiner's (NBME) subject exam is tomorrow for my OB/Gyn rotation.

Here's an example (from their website) of the kind of questions they ask.

1. A 27-year-old nulligravid woman has had severe
dysmenorrhea that has caused her to miss at least
2 days of work during each menstrual cycle for the past
year. She has occasional pain during sexual intercourse.
She weighs 50 kg (110 lb) and is 160 cm (63 in) tall.
Pelvic examination shows a normal-appearing vulva
and vagina. The cervix is pink with minimal
endocervical gland eversion. The uterus is normal in
size. The left ovary is 2 x 3 cm; the right ovary is 4 x 6
cm. Which of the following is the most likely cause of
her condition?
(A) Chronic appendicitis
(B) Endometriosis
(C) Pelvic congestion syndrome
(D) Polycystic ovarian disease
(E) Premenstrual syndrome

2. A 27-year-old nulligravid woman and her husband have
been unable to conceive for 12 months. She has never
used contraception. Menses occur at 28-day intervals,
and her last menstrual period was 2 weeks ago. She had
a single episode of pelvic inflammatory disease 4 years
ago and was treated with oral antibiotics. Vaginal
examination shows no abnormalities. Cervical cultures
are normal. Which of the following is the most
appropriate next step in diagnosis?
(A) Reevaluation in 6 months
(B) Ultrasonography of the abdomen
(C) Sperm penetration assay
(D) Hysterosalpingography
(E) Endometrial biopsy

3. A 30-year-old woman, gravida 2, para 1, comes for her
first prenatal visit at 26 weeks' gestation. Uterine size
is greater than expected for dates. Ultrasonography
shows fetal hydrops. Which of the following is the
most appropriate next step in diagnosis?
(A) Maternal HIV antibody test
(B) Maternal Rh status with antibody
screening
(C) Cervical and urine cultures for group
B streptococcus
(D) MRI of the fetus
(E) Amniocentesis for measurement of
α-fetoprotein level

Just thought you might be curious how they test us med students. Wish me luck tomorrow.
