A 25-year-old primigravida at 36 weeks gestation presents for a routine prenatal visit. Which assessment finding would be most concerning and require immediate further evaluation?
1Blood pressure of 128/82 mmHg with trace proteinuria
2Fundal height measuring 30 cm at 32 weeks gestation
3Fetal heart rate of 155 beats per minute with good variability
4Sudden onset of severe epigastric pain with visual disturbances✓ 정답
해설
Sudden severe epigastric pain with visual disturbances suggests severe preeclampsia or HELLP syndrome, an obstetric emergency. Other findings are within normal limits or less urgent.
Core Nursing ExplanationKey Concept Analysis: This question assesses the ability to recognize signs of a life-threatening obstetric emergency in a pregnant patient. The core theme is identifying preeclampsia with severe features and its progression to HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets). At 36 weeks gestation, the priority is to detect complications that threaten both maternal and fetal well-being.
Answer Rationale: Key Point! Option ④ describes classic symptoms of severe preeclampsia. Severe epigastric or right upper quadrant pain is a sign of liver capsule distention due to edema and ischemia, indicating possible HELLP syndrome. Visual disturbances (blurred vision, scotomata) indicate cerebral edema or vasospasm. This combination represents an imminent risk of eclampsia (seizures), placental abruption, hepatic rupture, or disseminated intravascular coagulation (DIC). This finding requires immediate evaluation, including lab work (CBC, liver enzymes, creatinine) and likely urgent delivery.
Distractor Analysis:
Watch out for confusion! Option ①: A blood pressure of 128/82 mmHg is within the normal range for pregnancy. Trace proteinuria can be common and non-specific. This does not meet the diagnostic threshold for preeclampsia (BP ≥140/90 mmHg on two occasions and proteinuria ≥1+).
Option ②: Fundal height (FH) of 30 cm at 32 weeks is actually appropriate. The general rule is FH in cm roughly equals gestational age in weeks (±2 cm). 30 cm at 32 weeks is within the normal variation. This finding would not be the most concerning.
Option ③: A fetal heart rate (FHR) of 155 bpm with good variability is a reassuring sign of fetal well-being. The normal FHR range is 110-160 bpm. Good variability indicates a healthy autonomic nervous system.
Related Concepts: This question integrates knowledge of normal prenatal assessment findings versus critical danger signs. It tests the nurse's role in triage and prioritization during prenatal visits. Understanding the pathophysiology of preeclampsia (vasospasm, endothelial damage) is key to recognizing its multi-system manifestations.
Concept Summary
Concept
Description
Clinical Significance
Preeclampsia
Hypertension (≥140/90) & proteinuria after 20 weeks gestation.
Leading cause of maternal & fetal morbidity/mortality.
Mild dizziness upon standing (orthostatic hypotension).
Proteinuria
Persistent 1+ or greater on dipstick, or ≥300 mg/24h.
Trace proteinuria, especially in a single sample.
Anatomy, Physiology & Pharmacology PointsPathophysiology: Preeclampsia involves abnormal placental development leading to widespread maternal vasospasm. This causes hypertension, reduced organ perfusion (kidneys, liver, brain, placenta), endothelial damage, and capillary leak. Liver Involvement: Vasospasm in hepatic arteries leads to periportal necrosis and hemorrhage, stretching Glisson's capsule → severe epigastric/RUQ pain. Drug of Choice: Magnesium sulfate is used for seizure prophylaxis in preeclampsia/eclampsia. It acts as a CNS depressant. Nurses must monitor for toxicity: loss of deep tendon reflexes (first sign), respiratory depression, cardiac arrest.
Memory TipsHELLP Triad: Remember the acronym: Hemolysis, Elevated Liver enzymes, Low Platelets. Danger Signs of Preeclampsia: Use the mnemonic HEADACHE:
Headache (severe, unrelieved),
Epigastric pain,
Altered vision,
Dyspnea/edema (sudden, severe),
Abnormal labs (platelets, liver enzymes),
Convulsions (eclampsia),
Hypertension,
Excessive proteinuria.
High-Frequency NCLEX Topics
Preeclampsia is a High Yield topic. The NCLEX-RN frequently tests:
1. Recognizing signs of severe preeclampsia/HELLP (as in this question).
2. Priority nursing interventions (e.g., administer MgSO4, maintain a dark/quiet environment).
3. Monitoring for complications of MgSO4 therapy.
4. Understanding that delivery of the placenta is the only cure for preeclampsia.
Watch Out for Question Variations!
* Instead of "most concerning finding," the question could ask: "The nurse's priority action is to:" (Answer: Notify the healthcare provider immediately, prepare for hospitalization/labs).
* It could present lab results: "Platelets 80,000/mm3, AST 250 U/L" and ask you to identify the syndrome (HELLP).
* It could shift to postpartum: "A patient 2 days postpartum develops severe headache and blurred vision." (Think: Watch out for confusion! Preeclampsia can occur up to 6 weeks postpartum!).
Nursing Clinical Practice GuideClinical Scenario: You are a nurse in a busy prenatal clinic. Maria, a 25-year-old first-time mother at 36 weeks, mentions during her check-in that she has had a "terrible burning pain" in her upper stomach for the past few hours and things look "a little fuzzy." She appears anxious.
Nursing Intervention Strategy:
1Immediate AssessmentQuickly take her to a private room. Assess vital signs, especially BP in both arms. Ask specific questions: "Can you describe the pain? Is it constant? Any headache, nausea, or seeing spots?" Perform a focused abdominal assessment, noting any tenderness.
2Safety & NotificationThis is a red flag. Do not wait. Immediately notify the physician or midwife while staying with the patient. Your report should be concise: "36-week primigravida with new onset severe epigastric pain and visual disturbances. BP is X/X."
3Preparation & MonitoringAnticipate orders for stat labs (CBC, liver function tests, creatinine, uric acid), a urinalysis for protein, and continuous fetal monitoring. Have oxygen and emergency equipment accessible. Keep the patient in a left lateral position to optimize placental blood flow.
4Patient Support & EducationKeep the patient calm. Explain what is happening without causing panic: "We need to check you and the baby carefully right now because these symptoms can be a sign that your body is under extra stress from the pregnancy."
Patient Safety and Precautions:
* Do not dismiss epigastric pain as "heartburn" without a thorough evaluation.
* Contraindication: Avoid administering antihypertensives like labetalol or nifedipine without a specific order, as rapid lowering of BP can compromise placental perfusion.
* Key Monitoring: Continuous monitoring of maternal BP, reflexes, respiratory status, and fetal heart rate is essential once severe preeclampsia is suspected.
Nursing Procedure & Medication Flow
If the diagnosis is confirmed and Magnesium Sulfate (MgSO4) is ordered:
1AdministrationTypically given IV via controlled infusion pump. A loading dose (e.g., 4-6 g over 20-30 min) is followed by a maintenance dose (e.g., 1-2 g/hr).
2Monitoring for Efficacy & Toxicity* Check deep tendon reflexes (patellar) hourly. Absent reflexes are the first sign of toxicity.
* Monitor respiratory rate hourly; must be >12 breaths/min.
* Monitor urine output hourly via Foley catheter; must be >30 mL/hr (Mg is excreted renally).
* Have calcium gluconate (the antidote for Mg toxicity) at the bedside.
3EnvironmentMaintain a quiet, dimly lit room to minimize sensory stimulation and risk of seizure.
A Word from Your Senior Nurse
"Trust your gut when a pregnant patient tells you something 'just doesn't feel right.' That severe epigastric pain is not typical pregnancy discomfort—it's the liver sending a major distress signal. In clinic or on the floor, you are the first line of defense. Catching preeclampsia early can literally save two lives. When you study, don't just memorize 'epigastric pain = preeclampsia.' Understand the 'why'—the vasospasm, the liver swelling—so when you hear it in report or from a patient, the connection fires instantly in your brain. That's the kind of critical thinking the NCLEX tests for and that makes an outstanding nurse."
Preeclampsia — A pregnancy-specific syndrome of hypertension (≥140/90 mmHg) and proteinuria (≥300 mg/24h) occurring after 20 weeks of gestation.
HELLP Syndrome — A severe variant of preeclampsia characterized by Hemolysis, Elevated Liver enzymes, and Low Platelet count.
Fundal Height — Measurement from the symphysis pubis to the top of the uterine fundus; used to estimate gestational age and fetal growth (should correlate with weeks of gestation ±2 cm).
Magnesium Sulfate — The drug of choice for seizure prophylaxis in patients with preeclampsia/eclampsia; nurses must monitor for signs of toxicity (loss of reflexes, respiratory depression).
Fetal Heart Rate Variability — Fluctuations in the baseline FHR; good variability is a reassuring sign of fetal central nervous system integrity and well-being.
