An 18-year-old female college student presents to the emergency department with pelvic pain. Initial laboratory work shows an elevated WBC count, elevated ESR, negative human chorionic gonadotropin, and normal urinalysis. During a pelvic examination, the patient experiences severe pain with any manipulation of the cervix. Sonography of the pelvis was ordered for suspected PID.

PID is still likely, even with normal transabdominal sonogram

What is the most common cause of bladder outlet obstruction?
PUV
What are the two types of IUD?
Paraguard (copper T) and Mirena
A 25-year-old woman is referred for a pelvic sonogram because of left lower quadrant pain. A pregnancy test is negative. The sonogram reveals a 2.0 cm unilocular, simple cyst adjacent to the left ovary. Which of the following statements is true regarding this finding?

A 41-year-old woman is seen by her obstetrician with vaginal bleeding and hyperemesis. Clinical examination reveals a uterus consistent with a 12-week gestation, which is inconsistent with her predicted 10-week gestation by last menstrual period. An ultrasound is performed and reveals a fetus without heart motion and a crown-rump length consistent with an 8-week gestation. An enlarged placenta is identified containing numerous small cystic lesions. This is most suggestive of which of the following?
Partial hydatidiform mole
How can septate uterus be treated?
Patient can have septum removed by hysteroscopy if infertility occurs

A patient with an IUD in place has a positive pregnancy test. A sonogram reveals a 7-week, viable gestation within the uterus.
