Double every 48 hours
Compared with a normal IUP, the ectopic pregnancy will have a:
Low hCG
The first sonographically identifiable sign of pregnancy is the:
Decidual reaction
The first definitive sonographic sign of an IUP is the recognition of a/an:
Gestational sac
The normal gestational sac will grow:
1 mm per day
During a first-trimester ultrasound examination, you note a cystic structure within the fetal head. This most likely represents:
Rhombencephalon
The herniation of the embryologic bowel into the base of the umbilical cord at 9 weeks is referred to as:
Physiologic bowel herniation
The most common pelvic mass associated with pregnancy is the:

The most common location of an ectopic pregnancy is the:
Ampullary portion of the uterine tube
All of he following are contributing factors for an ectopic pregnancy except:
- PID
- reproductive therapy
- contraceptive devise
- advanced paternal age
Advanced paternal age
All of the following are clinical features of an ectopic pregnancy except:
- pain
- vag bleeding
- shulder pain
- adnexal ring
Adnexal ring
All of the following are sonographic findings consistent with ectopic pregnancy except:
- decidual thickening
- complex free fluid within pelvis
- Bilateral, multiloculated ovarian cysts
- complex adrenal mass separate from ipsilateral ovary
Bilateral, multiloculated ovarian cysts
All of the following are consistent with a hydatidiform mole except:

low hCG
The most malignant form of gestational trophoblastic disease is:
Choriocarcinoma
A sonographic examination was performed on a pregnancy patient who complained of vaginal bleeding. Sonographically, a crescent-shaped anechoic area is noted adjacent to the gestational sac. The gestational sac contained a 6-week single live intrauterine pregnancy. What is the most likely diagnosis?
Subchorionic hemorrhage
All of the following would be associated with a lower-than-normal human chorionic gonadotropin level except:

All of the following are clinical findings consistent with a molar pregnancy except?
- vaginal bleeding
- hypertension
- uterine enlargement
- small for dates
