A nurse is caring for a 2-hour-old newborn in the nursery. The infant appears pink with some acrocyanosis, has a strong cry, and shows good muscle tone. Which action should the nurse prioritize first to ensure the newborn's safety and prevent complications?

A full-term newborn has just been delivered vaginally. The infant appears pink with some acrocyanosis, has a strong cry, and shows good muscle tone. The umbilical cord is still attached and pulsating.

Clearing the airway and establishing breathing is the priority per ABCs of emergency care, as respiratory adaptation is critical after birth. Other actions are important but secondary.

Core Nursing Explanation Key Concept Analysis: This question assesses the application of the ABC (Airway, Breathing, Circulation) priority framework in the immediate newborn period. While the infant appears stable with a strong cry and good tone, the Key Point! is that the initial nursing priority for any newborn is to ensure a patent airway and effective breathing to complete the transition from fetal to neonatal circulation. This is the first step in the standard sequence of newborn care immediately after delivery.

Answer Rationale: The correct answer is Clear the airway and establish effective breathing. Even with a strong cry, secretions in the oropharynx and nasopharynx can obstruct the airway. The nurse's first action is to position the infant, suction the mouth then nose if needed with a bulb syringe, and ensure the infant is breathing effectively. This supports the critical physiological shift where the lungs expand, pulmonary vascular resistance drops, and the foramen ovale and ductus arteriosus begin to close. All other care is secondary until effective respiration is confirmed.

Distractor Analysis:
Watch out for confusion! Option 1, "Perform immediate umbilical cord clamping and cutting," is incorrect. Current evidence-based practice, especially for vigorous term newborns, often supports delayed cord clamping (DCC) for 30-60 seconds to allow for placental transfusion, which increases iron stores and blood volume. Immediate clamping is not the priority and may deprive the infant of these benefits.
Option 2, "Administer vitamin K injection within the first hour," is a standard procedure to prevent Vitamin K Deficiency Bleeding (VKDB), but it is not the immediate life-sustaining priority. It is typically done after initial stabilization and often within the first few hours.
Option 3, "Begin breastfeeding initiation within 30 minutes," is an excellent practice for promoting bonding, stimulating milk production, and providing colostrum. However, it follows the establishment of a stable airway, breathing, and circulation. The infant must be physiologically stable first.

Related Concepts: This integrates neonatal transition, Apgar scoring (the described infant would likely score well), and the sequence of nursing interventions in the delivery room. Understanding that "pink with acrocyanosis" (blue hands and feet) is normal in the first 24-48 hours is also key.

Concept Summary
ConceptDescriptionNursing Implication
ABC PriorityAirway, Breathing, Circulation - the foundational sequence for all patient care, especially in emergencies or initial assessments.Always assess and intervene for airway patency and effective breathing first.
Neonatal TransitionThe physiological adaptation from intrauterine to extrauterine life, primarily involving the cardiopulmonary system.Nursing care focuses on facilitating lung expansion, thermoregulation, and circulatory changes.
Delayed Cord Clamping (DCC)Waiting 30-60 seconds before clamping the umbilical cord in vigorous newborns.Promotes placental transfusion, increasing iron stores and reducing anemia risk. It is now standard care.
AcrocyanosisBluish discoloration of the hands and feet due to peripheral vasoconstriction and immature peripheral circulation.A normal finding in newborns for the first 24-48 hours. Differentiate from central cyanosis (blue lips/torso), which is abnormal.

Umbilical CordWhite, gelatinous, 2 arteries & 1 vein, stops pulsating after clampingSingle umbilical artery (associated with anomalies), active bleeding, redness/drainage (infection)

Anatomy, Physiology & Pharmacology PointsPhysiology: The first breath causes a dramatic drop in pulmonary vascular resistance and increase in systemic vascular resistance. This pressure change functionally closes the foramen ovale (atrial septum) and begins the process of closing the ductus arteriosus (fetal shunt between pulmonary artery and aorta). A clear airway is essential for this first breath. • Pharmacology: Vitamin K (phytonadione) injection is given because newborns have a sterile gut at birth and cannot synthesize vitamin K, which is essential for the liver to produce clotting factors (II, VII, IX, X).

Memory TipsABCs come first, always! Before bonding, before meds, before feeding. "Airway is Always Before Anything Else." • For newborn priorities, think: Breathe, Warm, Feed. (Airway/Breathing, Thermoregulation/Drying, then Nutrition). • Acrocyanosis = "Acrocyanosis is Acceptable" in the newborn.

High-Frequency NCLEX Topics The ABC framework is the #1 most frequently tested concept on the NCLEX-RN. It is applied across all patient populations and settings. Newborn immediate care is a classic scenario to test this priority-setting skill. You will also be tested on distinguishing normal newborn characteristics (like acrocyanosis) from abnormal signs.

Watch Out for Question Variations! • The question could shift from "prioritize first" to "which finding requires immediate intervention?" – The answer would then be an abnormal finding like central cyanosis or apnea. • It could ask for the rationale for delayed cord clamping, testing your knowledge of evidence-based practice updates. • It could combine with medication administration, asking which medication is given first after stabilization – often erythromycin ophthalmic ointment (for ophthalmia neonatorum prevention) or vitamin K, but still after ABCs.

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse receiving a newborn in the nursery. The infant, "Baby Girl Smith," was born vaginally 10 minutes ago. She is wrapped in a dry blanket, has acrocyanosis, and is making small whimpering sounds. The mother is eager to hold her.

Nursing Intervention Strategy: 1. Assessment (A): While the report says she's stable, you immediately perform your own assessment. You observe chest rise, listen for clear breath sounds, and check heart rate via palpation of the umbilical stump or auscultation. You note the strong cry and good tone from the report. 2. Intervention (I): Your first hands-on action is to ensure the airway is clear. You position the infant on her back with the neck slightly extended (sniffing position). You use a bulb syringe to suction the mouth first (to avoid stimulating the nasopharynx and causing aspiration if the infant gasps), then the nose. You dry and stimulate if needed to encourage vigorous crying. 3. Continuing Care (C): Once breathing is effective, you prioritize thermoregulation by placing the infant skin-to-skin with the mother (if stable) or under a radiant warmer. You then proceed with identification bands, footprints, vitamin K and erythromycin administration, and weight/length measurements. You facilitate breastfeeding within the first hour during skin-to-skin contact.

Patient Safety and Precautions: • Suctioning: Always suction the mouth before the nose. Avoid deep or vigorous suctioning, which can cause bradycardia or tissue damage. • Thermoregulation: Newborns lose heat rapidly. Dry thoroughly immediately after birth and use pre-warmed blankets. Hypothermia increases metabolic demand and oxygen consumption, complicating transition. • Delayed Cord Clamping: Keep the infant at or below the level of the placenta until the cord is clamped if DCC is being performed, to facilitate blood flow.

Nursing Procedure & Medication Flow Immediate Newborn Care Sequence: 1. Airway: Suction mouth, then nose. 2. Breathing: Dry, stimulate, position. Assess for effective respirations. 3. Circulation: Assess heart rate (normal 110-160 bpm). Dry and warm to prevent cold stress. 4. Thermoregulation: Dry thoroughly, place skin-to-skin or under warmer. 5. Identification: Apply matching bands to mother and infant. 6. Prophylaxis: Administer Vitamin K IM (vastus lateralis muscle) and Erythromycin ophthalmic ointment. 7. Assessment: Perform full physical assessment, weight, measurements. 8. Nutrition: Assist with first breastfeeding or bottle feeding.

A Word from Your Senior Nurse "In the delivery room and nursery, your calm, systematic approach sets the stage for a healthy transition. Never let routine tasks overshadow the fundamental ABCs. That strong cry is music to our ears, but we still check the airway because a small mucus plug can change everything in seconds. Remember, you are the baby's first advocate outside the womb. Your priority-setting skills, grounded in solid pathophysiology (like understanding why breathing must come first), are what make you a safe and competent nurse from day one. This mindset is exactly what the NCLEX is testing!"
