NREMT Paramedic Cognitive ExamMedicalEasy
A 32-year-old female presents with acute onset of severe, crampy lower abdominal pain, vaginal spotting, and lightheadedness. She states her last menstrual period was 8 weeks ago and she has a history of pelvic inflammatory disease (PID). Her vital signs are BP 90/60 mmHg, HR 120 bpm, RR 22 bpm, SpO2 98% on room air. Abdominal examination reveals diffuse tenderness, more prominent in the lower quadrants, with guarding. Based on her presentation, what is the most immediate life-threatening concern?
- ARuptured ectopic pregnancy
- BPelvic inflammatory disease (PID) exacerbation
- CAppendicitis
- DOvarian cyst torsion
Show answer & explanationAnswer & explanation
Correct answer: A. Ruptured ectopic pregnancy
The patient's presentation with severe lower abdominal pain, vaginal spotting, amenorrhea (8 weeks since LMP), lightheadedness, and signs of hypovolemic shock (hypotension, tachycardia) strongly suggests a ruptured ectopic pregnancy. This condition can lead to rapid and life-threatening hemorrhage.
Why the other options are wrong
- B. PID exacerbation causes abdominal pain, fever, and vaginal discharge, but is less likely to cause acute hypovolemic shock and severe, acute pain with lightheadedness without other signs of infection.
- C. Appendicitis typically presents with periumbilical pain migrating to the right lower quadrant and does not usually cause vaginal spotting or signs of hypovolemic shock.
- D. Ovarian cyst torsion causes acute, severe abdominal pain and may cause nausea/vomiting, but typically does not cause vaginal spotting or the rapid onset of hypovolemic shock seen here.
Ruptured Ectopic Pregnancy
A life-threatening gynecological emergency where a fertilized egg implants outside the uterus, most commonly in the fallopian tube, and ruptures, leading to severe internal hemorrhage.
- Severe, acute unilateral lower abdominal pain
- Vaginal spotting/bleeding
- Signs of hypovolemic shock (tachycardia, hypotension, syncope/lightheadedness)
- History of amenorrhea (missed period)
