A 28-year-old pregnant woman at 32 weeks gestation presents to the emergency department with a 3-day history of fever, cough, and shortness of breath. She tests positive for COVID-19. What is the most important initial assessment the nurse should prioritize?

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 Explanation Key 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.

Side-by-Side Comparison!

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

Nursing Clinical Practice Guide Clinical 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:

1. 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.
2. Action Based on Findings: If SpO2 is
