Final answer:
The emergency department educated Ms. Miller on STIs and PID complications, and she was able to tolerate oral fluids before being sent home for outpatient management.
Step-by-step explanation:
The correct answer to the question is E. The emergency department educated Ms. Miller on the risk of sexually transmitted infections and explained the complications of pelvic inflammatory disease (PID), which can include tubo-ovarian abscess and tubal infertility. Ms. Miller was able to tolerate oral fluids, indicating that her condition improved enough for her to be sent home for outpatient management, contrary to options A and B which suggest hospital admission and inability to tolerate oral intake respectively. As such, options A, B, C, and D are incorrect.
