The nurse practitioner is evaluating a 28-year old female with a complaint of unilateral abdominal pain with associated dizziness, near syncope, and a small amount of bright red vaginal bleeding. The client reports her last menstrual period was over 8 weeks ago. On physical examination, the client has abdominal tenderness, cervical motion tenderness, and there is tissue present in the vaginal vault. The client appears ill and has orthostatic hypotension. The NP suspects ectopic pregnancy. Which lab finding would be highly indicative and warrant additional diagnostics?
