1Assess fetal heart rate and uterine contractions
2Evaluate maternal oxygen saturation and respiratory status✓ 정답
3Obtain complete blood count and inflammatory markers
4Check blood glucose levels and ketones
해설
In pregnant women with COVID-19, respiratory assessment is the priority because maternal oxygenation directly affects fetal well-being and rapid respiratory compromise can occur due to physiological changes of pregnancy. Other assessments are important but secondary to stabilizing the mother's respiratory status.
Core Nursing ExplanationKey Concept Analysis: This question tests the application of ABC (Airway, Breathing, Circulation) priority and Maternal Resuscitation Principles in a pregnant patient with a respiratory infection. The core principle is that in any emergency, stabilizing the mother is the first and most critical step to ensure fetal survival. A pregnant woman at 32 weeks with COVID-19 symptoms is at high risk for hypoxemia (low blood oxygen), which can rapidly lead to maternal decompensation and fetal distress.
Answer Rationale: Key Point! The correct answer is to Evaluate maternal oxygen saturation and respiratory status. This aligns with the primary survey (ABCs). Physiological changes of pregnancy, such as increased oxygen consumption and reduced lung reserve, make pregnant women more susceptible to rapid respiratory deterioration from illnesses like COVID-19. Assessing oxygen saturation (SpO2) and work of breathing provides immediate, critical data on the mother's ability to oxygenate herself and, by extension, the fetus. Remember: You must save the mother first to save the baby.
Distractor Analysis:
Watch out for confusion! Option ① (Assess fetal heart rate and uterine contractions) is a crucial secondary assessment. While fetal well-being is a major concern, it depends entirely on adequate maternal oxygenation and perfusion. Assessing the fetus before ensuring the mother is stable is incorrect prioritization.
Option ③ (Obtain complete blood count and inflammatory markers) is an important diagnostic step but is not the initial priority assessment. Lab work supports diagnosis and management but does not address an immediate life threat.
Option ④ (Check blood glucose levels and ketones) is more relevant for a patient with diabetes or hyperemesis gravidarum. While infection can affect glucose levels, it is not the most immediate threat in this scenario of fever, cough, and shortness of breath.
Related Concepts: This scenario integrates Obstetric Triage, Maternal Physiological Adaptations (increased cardiac output, decreased functional residual capacity), and the management of COVID-19 in pregnancy. Understanding that pregnancy is a state of relative immunocompromise and increased metabolic demand is key to anticipating rapid clinical changes.
Concept Summary
Concept
Key Takeaway
ABC Priority
Airway, Breathing, Circulation always come first, regardless of pregnancy status.
Maternal-Fetal Physiology
Fetal oxygenation is dependent on maternal oxygenation. Hypoxemia in the mother leads directly to fetal hypoxemia.
Pregnancy & Respiratory Compromise
Elevated diaphragm, increased O2 consumption, and decreased FRC make pregnant women prone to rapid desaturation.
Nursing Process in Triage
Assessment begins with identifying and managing immediate life threats (unstable vital signs) before focused or diagnostic assessments.

Assessment Priority in a Pregnant Patient
Rationale
When to Perform
Maternal Vital Signs & Respiratory Status
Ensures mother's stability, which is the prerequisite for fetal survival. Directly addresses the ABCs.
ALWAYS FIRST in an acute presentation with symptoms of distress.
Fetal Assessment (FHR, Contractions)
Evaluates fetal well-being, which is a direct reflection of the intrauterine environment (oxygen, perfusion).
SECONDARY, after maternal stability is addressed or concurrently if a second nurse is available.
Anatomy, Physiology & Pharmacology Points
Physiology: During pregnancy, Functional Residual Capacity (FRC) decreases by ~20% due to the upward displacement of the diaphragm by the enlarging uterus. This reduces the oxygen reserve, meaning a pregnant woman can desaturate much faster during a respiratory illness.
Physiology: Maternal oxygen consumption increases by 20-30%. The fetus is entirely dependent on the oxygen content in maternal blood delivered via the placenta.
Assessment: A normal maternal SpO2 is ≥95%. In pregnancy, an SpO2 of <94% is concerning and requires immediate intervention (e.g., supplemental oxygen).
Memory Tips
M.O.M. First:Mother's Oxygenation Matters First. Stabilize the mom to save the baby.
The ABC Rule: In any emergency, your brain should automatically go: Airway? Breathing? Circulation? This question is a classic test of "B" for Breathing.
High-Frequency NCLEX Topics
This is a classic prioritization (delegation/assignment) question. The NCLEX-RN loves to test if you can distinguish between what is important and what is the priority. Remember: Life-threatening conditions (compromised ABCs) always take precedence over other important but non-urgent assessments or interventions.
Watch Out for Question Variations!
Shift in Symptoms: If the scenario added "severe abdominal pain and vaginal bleeding," the priority might shift to assessing for placental abruption or other obstetric emergencies alongside ABCs.
Shift in Timing: "After stabilizing the mother's respiratory status, what is the next priority assessment?" The answer would then be fetal heart rate and uterine activity.
Shift in Condition: "A pregnant woman with known diabetes presents with fever and cough..." Then checking blood glucose (option 4) becomes much more relevant, but ABCs still come first.
Nursing Clinical Practice GuideClinical Scenario: You are the triage nurse in the Labor & Delivery unit. Ms. Lopez, 32 weeks pregnant, is brought in by her partner. She is leaning forward, using accessory muscles to breathe, and can only speak in short phrases. She reports a fever of 101.5°F (38.6°C) and a worsening cough.
Nursing Intervention Strategy:
Immediate Assessment (Priority): While guiding her to a bed, apply a pulse oximeter. Simultaneously, visually assess her work of breathing (retractions, nasal flaring), count her respiratory rate, and listen for lung sounds. Your goal is to get an SpO2 reading within 60 seconds of arrival.
Action Based on Findings: If SpO2 is <94%, initiate supplemental oxygen via nasal cannula immediately and call for the provider/Rapid Response if severe distress. Obtain full vital signs (BP, HR, Temp).
Secondary Assessment: Once oxygenation is addressed, apply the external fetal monitor (tocodynamometer and ultrasound transducer) to assess fetal heart rate (FHR) and for any uterine contractions.
Diagnostic & Supportive Care: Facilitate lab draws (CBC, CRP), administer antipyretics as ordered, ensure IV access, and provide positioning for comfort (semi-Fowler's or tripod position to ease breathing).
Patient Safety and Precautions:
Infection Control: Place the patient in a negative pressure room if available. Use appropriate PPE (N95 respirator, gown, gloves, eye protection) as per droplet/airborne precautions for COVID-19.
Monitoring: Continuous pulse oximetry and frequent vital sign checks (every 15-30 minutes initially) are mandatory. A sudden drop in SpO2 or a rising respiratory rate can indicate rapid deterioration.
Fetal Monitoring: Be aware that maternal fever (maternal hyperthermia) can cause fetal tachycardia. Differentiate this from tachycardia due to fetal hypoxemia.
Nursing Procedure & Medication FlowProcedure: Applying Supplemental Oxygen to a Pregnant Patient
Explain the procedure to the patient: "Ms. Lopez, I'm going to give you some extra oxygen through this tube in your nose to help you and your baby breathe easier."
Start with a low flow (e.g., 2-4 L/min via nasal cannula) and titrate upward to achieve SpO2 ≥95%.
Monitor skin under the cannula and nares for pressure injury.
Document: Oxygen delivery device, flow rate (L/min), and patient's SpO2 before and after application.
Medication Consideration: Antipyretics like Acetaminophen (Tylenol) are safe in pregnancy for fever reduction. Avoid NSAIDs (e.g., Ibuprofen) in the third trimester due to the risk of premature closure of the fetal ductus arteriosus.
A Word from Your Senior Nurse
"In the chaos of triage, it's easy to get pulled in multiple directions—the worried family, the beeping monitors, the lab calling with results. Your anchor must always be the ABCs. Look at your patient first, not the computer. A pregnant woman working hard to breathe is a red flag that demands your immediate action. By securing her airway and oxygenation, you are doing the single most important thing for both your patients: the mother and the baby inside her. This fundamental principle will guide you through countless emergencies, on the NCLEX and at the bedside."
ABC Priority — The fundamental sequence for assessing and treating life-threatening conditions: Airway, Breathing, Circulation.
Maternal Hypoxemia — Low oxygen levels in the mother's blood, which directly compromises fetal oxygenation and can lead to fetal distress.
Functional Residual Capacity — The volume of air remaining in the lungs after a normal exhalation. Decreases in pregnancy, reducing oxygen reserve.
Fetal Tachycardia — A fetal heart rate baseline greater than 160 bpm. Can be caused by maternal fever, infection, or fetal hypoxemia.
Pulse Oximetry — A non-invasive method to monitor the oxygen saturation of a patient's blood. Critical for assessing respiratory status.
