A nurse in the emergency department is caring for a client who reports abrupt, sharp, right-sided lower quadrant abdominal pain and bright red vaginal bleeding. The client states, 'I missed one menstrual cycle and cannot be pregnant because I have an intrauterine device.' The nurse should suspect which of the following?
Correct Answer: B
Rationale: The correct answer is B: Ectopic pregnancy. Given the client's symptoms of right-sided lower quadrant abdominal pain, vaginal bleeding, missed menstrual cycle, and presence of an intrauterine device, these are classic signs of an ectopic pregnancy. Ectopic pregnancy occurs when a fertilized egg implants outside the uterus, commonly in the fallopian tube, leading to abdominal pain and vaginal bleeding. The other choices are incorrect because:
A: Missed abortion would typically present with cramping, bleeding, and passage of tissue.
C: Severe preeclampsia is characterized by high blood pressure and proteinuria, not the symptoms described.
D: Hydatidiform mole would typically present with vaginal bleeding and uterine enlargement, but not the sharp abdominal pain described.
