A 28-year-old woman at 10 weeks gestation presents to the emergency department with moderate vaginal bleeding and cramping. During assessment, the nurse notes that the cervical os is closed and fetal heart tones are present. What is the most appropriate nursing assessment priority for this client?

해설
In threatened abortion with a closed cervix and present fetal heart tones, the priority is monitoring vital signs and assessing for hypovolemic shock to ensure maternal hemodynamic stability. Other options are less urgent as they do not address the immediate risk of significant blood loss.

Core Nursing Explanation Key Concept Analysis: This question assesses the ability to prioritize nursing care for a patient experiencing vaginal bleeding in the first trimester. The key is to differentiate between types of early pregnancy loss based on cervical status and fetal viability. The scenario describes a Threatened abortion (miscarriage): vaginal bleeding with a closed cervical os and present fetal heart tones (FHT). This indicates the pregnancy is still viable, and the immediate goal is to maintain that viability and ensure maternal stability. The greatest risk is progression to significant blood loss.

Answer Rationale: Key Point! The priority is always ABCs (Airway, Breathing, Circulation) and hemodynamic stability. For any patient with bleeding, the nurse must first assess for signs of hypovolemic shock (e.g., tachycardia, hypotension, tachypnea, pallor, cool/clammy skin, decreased urine output). Monitoring vital signs provides critical data to detect shock early. This action is non-invasive, immediate, and forms the foundation for all subsequent decisions.

Distractor Analysis:
Watch out for confusion! Option ② (Prepare for surgery) is incorrect because a closed os and present FHT indicate a threatened, not an inevitable or incomplete, abortion. Immediate surgical intervention (like a Dilation and Curettage or D&C) is not indicated at this point. The plan is typically observation and possibly progesterone support.
Option ③ (Administer pain medication) addresses comfort, which is important, but patient safety (assessing for shock) always takes precedence over comfort in the nursing hierarchy of needs.
Option ④ (Obtain urine for hCG) is a diagnostic step, but it is not a priority in an acute care setting with active bleeding. Serum quantitative hCG levels might be ordered later to monitor trend, but a urine test does not guide immediate emergency management.

Related Concepts: Understanding the classification of spontaneous abortion is crucial:
  • Threatened: Bleeding, closed os, viable pregnancy.
  • Inevitable: Bleeding, open (dilated) os, may or may not have tissue passage.
  • Incomplete: Bleeding, open os, some products of conception (POC) expelled, some retained.
  • Complete: All POC expelled, bleeding subsides, os closes.
  • Missed: Fetal demise, no expulsion, os closed.
The nursing priority shifts if the cervix is open or FHT are absent, potentially making preparation for surgery or managing expectant miscarriage the priority.

Anatomy, Physiology & Pharmacology Points
  • Physiology: Bleeding in early pregnancy often originates from the decidua (uterine lining) at the site of placental implantation. A closed os helps prevent infection and may allow the pregnancy to continue.
  • Pharmacology: In some cases of threatened abortion, progesterone supplementation may be prescribed to support the uterine lining, but this is not an emergency intervention.
  • Lab Values: Monitor decreasing H&H (Hemoglobin & Hematocrit) as a sign of ongoing blood loss. Normal first-trimester hCG should roughly double every 48-72 hours; a low or falling level suggests non-viability.

Memory Tips
  • Think "Closed = Caution, Open = Operation": Closed cervical os (threatened) → caution and monitor. Open cervical os (inevitable/incomplete) → likely operation (D&C).
  • Priority Mnemonic: "Bleeding? Blood pressure first!" Always assess circulation (vital signs) before anything else.

High-Frequency NCLEX Topics This is a classic prioritization and maternal emergency question. The NCLEX loves to test your ability to distinguish between different types of pregnancy loss and apply the ABC priority framework. Remember: stable cervix + viable fetus = conservative management; unstable patient or open cervix = prepare for more urgent intervention.
Watch Out for Question Variations!
  • Symptom Change: "The client's bleeding increases and she passes clots. The nurse now notes the cervical os is 2 cm dilated." → Priority shifts to preparing for D&C.
  • Vital Sign Change: "The client's heart rate is 120 bpm and blood pressure is 88/50 mmHg." → This indicates hypovolemic shock; priority becomes initiating IV fluids, oxygen, and notifying the provider immediately.
  • Different Diagnosis: If the question adds "severe unilateral pelvic pain" and a positive pregnancy test, think ectopic pregnancy—a true surgical emergency.

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the triage nurse in the ED. Maria, 28, is brought in by her partner. She is anxious, holding her lower abdomen, and states she has been bleeding moderately for 3 hours with cramping similar to a bad period. She is 10 weeks pregnant by her last menstrual period (LMP).

Nursing Intervention Strategy:
  1. Immediate Assessment (Priority): Escort to a private room. While obtaining a brief history, simultaneously assess:
    • Vital Signs: Blood pressure, heart rate, respiratory rate, oxygen saturation. Compare to baseline if known.
    • Signs of Shock: Skin color (pallor), temperature (cool/clammy), capillary refill (>3 seconds), level of consciousness (restlessness can be early sign).
    • Bleeding Quantification: Ask about pad count saturated per hour. Avoid vaginal exam unless specifically trained and ordered; the cervical assessment in the question is typically done by a provider.
  2. Stabilization:
    • Establish IV access with a large-bore catheter (e.g., 18-gauge) for possible fluid resuscitation or blood transfusion.
    • Administer oxygen via nasal cannula if indicated by low SpO2 or signs of shock.
    • Position the patient in a left lateral recumbent position if no signs of shock, or flat with legs elevated if hypovolemia is suspected, to improve placental and systemic perfusion.
  3. Ongoing Monitoring & Support:
    • Continuous fetal heart rate monitoring if available and gestation is appropriate.
    • Provide emotional support and clear explanations. The fear of losing the pregnancy is profound.
    • Prepare for possible diagnostics: transvaginal ultrasound (to confirm viability and location of pregnancy) and blood work (CBC, quantitative hCG, blood type and Rh).
Patient Safety and Precautions:
  • Rh Factor: A critical nursing responsibility is to verify the patient's blood type and Rh status. If the patient is Rh-negative, she will likely need Rho(D) immune globulin (RhoGAM) within 72 hours of the bleeding event to prevent Rh isoimmunization in future pregnancies.
  • Infection Prevention: Use strict aseptic technique if any perineal care is provided. Instruct the patient on perineal hygiene.
  • Do NOT: Insert anything into the vagina (tampons, douches). Discourage sexual intercourse (pelvic rest) until cleared by the provider.

Nursing Procedure & Medication Flow For Threatened Abortion Management:
  1. Assessment Phase: VS, shock signs, pad count, pain level (use a scale 0-10).
  2. Monitoring Phase: Document VS trends. Weigh saturated pads (1 gram = 1 mL blood) if bleeding is heavy for objective measurement.
  3. Medication Phase (if ordered):
    • Progesterone: May be given vaginally or intramuscularly. Explain its role in supporting the pregnancy.
    • Analgesics: Acetaminophen is typically first-line. Avoid NSAIDs (e.g., ibuprofen) as they can affect platelet function and potentially increase bleeding risk.
    • RhoGAM: Verify order, confirm Rh-negative status, administer IM in the deltoid or vastus lateralis muscle. Document lot number and expiration date.

A Word from Your Senior Nurse "In obstetrics, bleeding is always an alarm bell. Your calm, systematic assessment is the first step in a potential emergency. Remember, you're caring for two patients. While we hope for the best, we must prepare for the worst. Your priority is to keep the mother hemodynamically stable—that is the foundation upon which any chance for the pregnancy rests. In clinicals and on the NCLEX, let the principle 'Airway, Breathing, Circulation' guide you through the noise of any scenario. And never forget the profound emotional care needed in these moments; a gentle hand and a listening ear are powerful nursing interventions too."
