A 28-year-old woman presents to the emergency department with a 6-week history of amenorrhea, lower abdominal pain, and vaginal spotting. Which assessment finding would be most indicative of a ruptured ectopic pregnancy?
1Positive pregnancy test with beta-hCG levels of 2,000 mIU/mL
2Unilateral pelvic pain radiating to the shoulder
3Blood pressure 90/60 mmHg with heart rate 110 bpm✓ 정답
4Absence of intrauterine gestational sac on transvaginal ultrasound
해설
Hypotension and tachycardia indicate hemodynamic instability from internal bleeding due to rupture, requiring immediate surgery. Other findings suggest ectopic pregnancy but not imminent life-threat.
Clinical Judgment
This question evaluates your ability to identify the most definitive assessment finding indicating a Rupture, an emergency complication of an Ectopic Pregnancy. The core lies in the 'Recognize Cues' and 'Prioritize Hypotheses' stages of the Clinical Judgment Measurement Model (CJMM), requiring you to select the single Critical Cue among multiple clues that most clearly indicates a life-threatening condition. The correct answer, Blood pressure 88/50 mmHg, Heart rate 120 bpm, is a clear sign of Hypovolemic Shock requiring a Notify HCP! response. This signifies that acute internal hemorrhage from a rupture is already in progress, which can lead to death without immediate surgical intervention. The other options contribute to the diagnosis or symptoms of an ectopic pregnancy but do not demonstrate such clear hemodynamic instability.
Memory TipRupture = Rapid Response needed! An ectopic pregnancy rupture involves Rapid blood loss and requires a Rapid response. Remember the vital signs as "Pressure down, Pulse up."
KR vs US
In Korea, early diagnosis may be more common due to the widespread availability of ultrasound, but the US NCLEX scenarios emphasize the classic, dramatic case of a ruptured ectopic pregnancy arriving at the emergency room. There is a distinct culture in the US where nurses prioritize assessing the patient's Hemodynamic Status and use changes in vital signs as the primary criterion for reporting to a physician.

Clinical Practice Guide
When caring for a patient with suspected or diagnosed ectopic pregnancy:
1. Signs to immediately report (Notify HCP!): hypotension, tachycardia, pallor, sweating, dizziness, shoulder pain (blood in the abdominal cavity irritates the diaphragm).
2. Emergency measures: Secure two large-bore (18G or larger) IV lines, prepare fluid administration, prepare for blood type and crossmatch, surgical consent and preparation.
3. Safety precautions: Never deeply palpate the abdomen or administer an enema. This can trigger rupture.
Caution
This is a common pitfall in SATA (Select All That Apply) questions. For the question "What are the signs of an ectopic pregnancy?", all options (positive pregnancy test, unilateral pain, ultrasound findings, vital sign changes) can be correct. However, in questions that ask about priority, such as "What is the most specific sign of a ruptured ectopic pregnancy?" or "Which finding requires immediate intervention?", only hemodynamic instability is the correct answer.
핵심 개념
Ectopic Pregnancy — Ectopic pregnancy. A condition where the fertilized egg implants outside the uterine lining, most commonly in the fallopian tube. It can progress to a life-threatening emergency.
Hypovolemic Shock — Hypovolemic shock. A condition where tissue perfusion becomes insufficient due to a sudden decrease in circulating blood volume, leading to damage to vital organs. A major cause of death in ruptured ectopic pregnancy.
Shoulder Pain (Kehr's Sign) — Scapular pain (Kehr's sign). Referred pain in the shoulder area caused by irritation of the diaphragm due to intra-abdominal bleeding. A sign that may appear when an ectopic pregnancy ruptures.
Beta-hCG (Human Chorionic Gonadotropin) — Human chorionic gonadotropin. It is secreted by the placenta during pregnancy and serves as the basis for pregnancy tests. In ectopic pregnancy, the rise in levels may be slower than in normal pregnancy.
Transvaginal Ultrasound — Transvaginal ultrasound. The gold standard test for diagnosing ectopic pregnancy. Used to check for the presence and location of an intrauterine gestational sac, and the presence of free fluid (bleeding) in the abdominal cavity.
