A 25-year-old woman presents to the emergency department with severe left lower abdominal pain, vaginal spotting, and dizziness. Her last menstrual period was 7 weeks ago. Vital signs show BP 85/55 mmHg, HR 120 bpm, and temperature 98.6°F. Transvaginal ultrasound reveals an empty uterus and a 3.5 cm mass in the left fallopian tube with free fluid in the pelvis. What is the priority nursing intervention?

The patient appears pale and anxious, reporting that the pain started suddenly 2 hours ago and has been worsening. She denies any previous history of pelvic inflammatory disease or sexually transmitted infections but mentions she had fertility treatments 6 months ago.
해설
Priority is establishing large-bore IV access and preparing for emergency surgery due to signs of ruptured ectopic pregnancy with hemorrhage (hypotension, tachycardia, free fluid). Pain management and history are less urgent.

Core Nursing Explanation This question presents a classic case of a ruptured ectopic pregnancy, a life-threatening obstetric emergency. The core nursing concept is prioritization based on the ABCs (Airway, Breathing, Circulation) and recognizing signs of hypovolemic shock due to internal hemorrhage. Key Concept Analysis An ectopic pregnancy is the implantation of a fertilized ovum outside the uterine cavity, most commonly in the fallopian tube. As the embryo grows, it can cause the tube to rupture, leading to severe intra-abdominal bleeding. The patient's symptoms—sudden severe unilateral abdominal pain, vaginal spotting, dizziness, hypotension (BP 85/55 mmHg), and tachycardia (HR 120 bpm)—are hallmark signs of rupture and shock. The ultrasound finding of an empty uterus, an adnexal mass, and free fluid (blood) in the pelvis confirms the diagnosis. Answer Rationale Key Point! In any patient with suspected internal hemorrhage and signs of shock, the priority nursing interventions focus on restoring and supporting circulation. 1. Establish large-bore IV access (e.g., two 18-gauge or larger IV catheters) is critical for rapid fluid resuscitation with crystalloids (e.g., Normal Saline or Lactated Ringer's) to combat hypovolemia. 2. Prepare for emergency surgery (typically a salpingectomy or salpingostomy) is the definitive treatment to stop the bleeding. Preparation includes obtaining informed consent, completing pre-operative checklists, and notifying the operating room team. These actions directly address the life-threatening problem of hemorrhage and shock, aligning with the nursing process where safety and physiological stability are always the highest priorities. Distractor Analysis Watch out for confusion! While all options are relevant to patient care, they are not the priority in this emergency context. • Option 1 (Analgesics): Pain management is a comfort measure and a valid nursing action, but administering analgesics (especially opioids) to a hypotensive patient can worsen hypotension and mask changes in clinical status. Stabilizing the patient's hemodynamics comes first. • Option 2 (Obtain history/Perform exam): A thorough assessment is foundational to nursing. However, in an emergency with clear signs of shock, taking time for a detailed history and pelvic exam delays life-saving interventions. A focused assessment (vital signs, level of consciousness) is sufficient initially. • Option 3 (Prepare for blood transfusion): The patient will likely need a blood transfusion due to significant blood loss. However, the immediate steps are to secure IV access to administer fluids and blood products and to prepare for surgery to control the source of bleeding. "Preparing for transfusion" often follows establishing IV access and obtaining blood samples for type and crossmatch. Related Concepts This scenario integrates knowledge of women's health (ectopic pregnancy risk factors like PID, infertility treatments), pathophysiology (hemorrhagic shock), and emergency nursing principles (triage, the ABC approach). Understanding that a ruptured ectopic pregnancy is a surgical emergency is paramount.
Concept SummaryEctopic Pregnancy: Implantation outside the uterus; most common site is the fallopian tube (tubal pregnancy). • Classic Triad: Abdominal pain, vaginal bleeding, and a positive pregnancy test in a woman of childbearing age. • Signs of Rupture & Shock: Sudden, severe pain; shoulder pain (referred from diaphragmatic irritation); hypotension; tachycardia; pallor; dizziness. • Priority Nursing Actions: ABCs, large-bore IV access, oxygen administration, rapid preparation for surgery.
Side-by-Side Comparison!
ConditionKey FeaturesPriority Nursing Intervention
Ruptured Ectopic PregnancySudden severe unilateral pain, signs of shock (hypotension, tachycardia), positive pregnancy test, free fluid on ultrasound.Establish IV access, prepare for emergency surgery.
Spontaneous Abortion (Miscarriage)Cramping abdominal pain, vaginal bleeding (may be heavy), passing of tissue, closed cervical os (in threatened abortion).Monitor bleeding, provide emotional support, prepare for possible dilation & curettage (D&C).
Ovarian Cyst RuptureSudden unilateral pain, may have minimal vital sign changes unless significant hemorrhage occurs. No positive pregnancy test.Pain management, monitor vital signs and for signs of internal bleeding.

Anatomy, Physiology & Pharmacology PointsAnatomy: The fallopian tube is not designed to expand like the uterus. Embryonic growth leads to stretching, ischemia, and eventual rupture. • Physiology: Internal bleeding into the peritoneal cavity causes hypovolemia → decreased cardiac output → compensatory tachycardia and vasoconstriction → if untreated, progresses to irreversible shock. • Pharmacology: Initial fluid resuscitation uses isotonic crystalloids (Normal Saline, Lactated Ringer's). Blood products (packed red blood cells) are given based on hemoglobin/hematocrit and clinical response. Rh(D) immune globulin (RhoGAM) must be administered to Rh-negative patients after surgery.
Memory TipsAcronym: SHOCK for ruptured ectopic pregnancy priorities: Secure large-bore IVs, Have O2 ready, Obtain consent for OR, Call lab for type & cross, Keep patient NPO. • Association: Think "Tube + Blood = Trouble." A tubal (ectopic) pregnancy with bleeding is a surgical trouble that needs immediate IV access.
High-Frequency NCLEX Topics The NCLEX-RN heavily tests prioritization and emergency response. Ectopic pregnancy is a classic scenario that tests your ability to: 1. Recognize signs of hypovolemic shock. 2. Apply the ABC (Airway, Breathing, Circulation) framework. 3. Distinguish between urgent and non-urgent nursing actions. 4. Understand the definitive treatment for a ruptured ectopic pregnancy.
Watch Out for Question Variations! • Instead of asking for the priority intervention, the question might ask: "The nurse anticipates an order for which laboratory test?" (Answer: Blood type and crossmatch). • Or: "Which assessment finding requires immediate intervention?" (Answer: BP 85/55 and HR 120). • It could also shift to post-op care: "Following a salpingectomy for a ruptured ectopic pregnancy, the nurse should monitor for which complication?" (Answer: Signs of continued hemorrhage or infection).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario You are the triage nurse in the ED when Ms. Jones, a 25-year-old, is brought in by her partner. She is clutching her lower abdomen, pale, diaphoretic, and saying she feels like she's going to faint. Her partner states she has been bleeding lightly and had sudden terrible pain. Nursing Intervention Strategy 1. Immediate Assessment (30 seconds): Check responsiveness, observe work of breathing, and palpate for a radial pulse (rapid, thready). This quick ABC check confirms instability. 2. Action (Simultaneous if possible): • Shout for help/activate the emergency response protocol. • Apply oxygen via non-rebreather mask at 10-15 L/min. • Establish TWO large-bore IV lines (16- or 18-gauge) in large veins (e.g., antecubital). Begin a rapid infusion of Normal Saline or Lactated Ringer's. • Monitor vital signs continuously (automatic blood pressure cuff, pulse oximeter, cardiac monitor). • Notify the physician/advanced practice provider STAT and relay your findings: "Possible ruptured ectopic, BP 85s, HR 120s, two large-bore IVs established, fluids running wide open." 3. Preparation for OR: • Ensure the consent form is signed. • Remove all jewelry, dentures. • Administer pre-operative antibiotics as ordered. • Draw labs per protocol (CBC, type and crossmatch, coagulation studies). • Keep the patient NPO (nothing by mouth). • Prepare for rapid transport to the operating room. Patient Safety and PrecautionsKey Point! Do not leave the unstable patient alone. Delegate tasks like gathering equipment or calling the lab to other team members. • Avoid placing the patient in Trendelenburg position if there is respiratory distress, as it can increase diaphragmatic pressure. • Handle the patient gently; movement can exacerbate pain and bleeding. • Communication: Provide clear, calm explanations to the patient and family. "We believe there is internal bleeding. We need to take you to surgery right away to stop it."
Nursing Procedure & Medication Flow IV Access & Fluid ResuscitationProcedure: Use aseptic technique. For rapid infusion, use pressure bags on IV fluid bags. The goal is to restore intravascular volume. • Calculation: A 1-liter bag of Normal Saline through a 16-gauge IV with a pressure bag can infuse in less than 10 minutes. • Medication: Blood products are the next step after crystalloids. Verify the blood product per hospital policy (two-nurse check). Infuse initially as fast as tolerated to restore volume, then adjust rate based on vital signs.
A Word from Your Senior Nurse "Nursing is not just about carrying out physician orders — it's about being the frontline guardian for your patients! In a case like this, your rapid, organized response is what bridges the gap between collapse and survival. You are the one who sees the pallor, feels the rapid pulse, and initiates the life-saving actions before the official orders even arrive. When studying for your boards, don't just memorize 'ectopic pregnancy = surgery.' Connect it to the feeling of a thready pulse and the sound of a pressure bag inflating. That clinical thinking — recognizing a pattern of shock and acting — is what the NCLEX tests and what makes an exceptional nurse. Always ask yourself: 'What is the immediate threat to life, and what can I do right now to fix it?'"
