A 17-year-old female presents to your ED with abdominal pain. Her vital signs are as follows: BP 90/60, HR 120, RR 16, and SpO2 99%. LMP is unknown. A urine pregnancy test is pending. She is awake and alert but looks uncomfortable so you decide to perform a bedside ultrasound:

A. Obtain CBC, BMP, and give a bolus of cystalloid

B. Obtain a serum quantitative hCG level 

C. Await the urine pregnancy test result



















D. This patient has a ruptured ectopic pregnancy until proven otherwise. She is hemodynamically unstable with a positive FAST exam concerning for hemorrhagic shock. Therefore, OBGYN needs to be consulted stat for emergent operative intervention. Lab testing will be a part of her care but should not delay immediate surgical intervention in any way.


This is what a tubal ectopic pregnancy may look like on a transvaginal ultrasound with the characteristic “ring of fire” sign of hypervascularity.
