Bronchiolitis and Respiratory Syncytial Virus (RSV)
A 9-month-old infant with respiratory syncytial virus (RSV) bronchiolitis is admitted to the pediatric unit. The infant has increased work of breathing, nasal flaring, and subcostal retractions. Which nursing intervention should be the highest priority?
1Administer bronchodilators as prescribed to improve airway patency
2Provide chest physiotherapy to mobilize secretions
3Encourage frequent oral fluid intake to prevent dehydration
4Position the infant in semi-Fowler's position to optimize breathing✓ 정답
해설
Positioning in semi-Fowler's is the highest priority to optimize breathing and reduce work of breathing in an infant with RSV bronchiolitis showing respiratory distress. Other interventions are less immediate or potentially harmful in acute distress.
Core Nursing ExplanationKey Concept Analysis: This question tests the priority nursing intervention for an infant with Respiratory Syncytial Virus (RSV) bronchiolitis in acute respiratory distress. The pathophysiology involves viral infection causing inflammation, edema, and mucus plugging in the small airways (bronchioles), leading to air trapping, increased airway resistance, and increased work of breathing. The infant's signs—increased work of breathing, nasal flaring, and subcostal retractions—are classic indicators of Key Point!moderate to severe respiratory distress. The priority is always the ABCs (Airway, Breathing, Circulation). In this case, the immediate threat is to Breathing.
Answer Rationale: Key Point! Positioning the infant in a semi-Fowler's position (head of bed elevated 30-45 degrees) is the highest priority because it is a non-invasive, immediate, and safe intervention that uses gravity to optimize lung expansion and decrease the work of breathing. It helps the diaphragm descend more easily, reduces pressure from abdominal contents on the lungs, and can improve oxygenation. This intervention can be performed instantly by the nurse without waiting for an order and directly addresses the primary problem of respiratory distress.
Distractor Analysis:
Watch out for confusion! Option ①: While bronchodilators (like albuterol) are sometimes prescribed for RSV, their efficacy is controversial and not consistently recommended because the primary pathology is inflammation and mucus plugging, not bronchospasm. Administering medication is important but is not the highest immediate priority when the infant is in visible distress. The nurse must first position the patient to optimize breathing.
Option ②: Key Point!Chest physiotherapy (CPT) or postural drainage is generally contraindicated in the acute phase of RSV bronchiolitis. It can increase airway irritation, cause fatigue, and worsen respiratory distress in an already compromised infant. It is not a priority and may be harmful.
Option ③: Encouraging oral fluids is important to prevent dehydration from tachypnea and poor feeding. However, in an infant with significant respiratory distress, attempting to feed or give fluids orally can increase the risk of aspiration and further compromise the airway. Fluid management is crucial but secondary to securing adequate oxygenation and ventilation. IV fluids may be needed instead.
Related Concepts: The nursing process dictates assessing and intervening for the most life-threatening problem first. For pediatric respiratory conditions, signs of distress (retractions, grunting, nasal flaring) are critical assessment findings. Supportive care (positioning, humidified oxygen, suctioning) is often the cornerstone of RSV management.
Concept Summary
Clears nasal secretions to improve airflow. Can be done after positioning.
High (Supportive)
IV Fluids
Prevents/treats dehydration from poor PO intake and tachypnea.
Medium (Essential but not first for distress)
Bronchodilator Trial
May be tried but evidence is weak; not a first-line or priority intervention.
Low/Contingent
Anatomy, Physiology & Pharmacology Points
Physiology: Retractions occur when the infant uses accessory muscles and pulls in soft tissue between/below ribs due to high negative intrapleural pressure needed to overcome airway obstruction.
Pharmacology: Ribavirin is an antiviral for severe RSV but rarely used. Palivizumab is a monoclonal antibody for prophylaxis in high-risk infants, not treatment.
Memory Tips
ABCs Rule: Always think Airway, Breathing, Circulation. The infant is struggling to breathe (B), so fix that first.
RSV = Rest, Suction, Ventilate (support). Positioning facilitates all of these.
No CPT for RSV! Remember: "Chest Percussion = Caution in Pediatric RSV" (it's usually contraindicated in acute phase).
High-Frequency NCLEX Topics
NCLEX loves testing priority-setting in pediatric respiratory illnesses. RSV is a classic case. Expect questions on: 1) Recognizing signs of respiratory distress, 2) Choosing the first or most important nursing action, and 3) Knowing contraindicated interventions (like CPT).
Watch Out for Question Variations!
Instead of asking for the priority intervention, it might ask: "The nurse notes subcostal retractions in an infant with RSV. Which action should the nurse take first?" (Answer is still positioning/assessing airway).
It could present a scenario where the infant's oxygen saturation is 88%. The priority then shifts to administering supplemental oxygen per protocol while positioning.
A question might ask about parent education for RSV home care: Focus on suctioning, hydration signs, and when to return to the hospital (e.g., worsening retractions).
Nursing Clinical Practice GuideClinical Scenario: You are the nurse on a pediatric unit. You receive a 9-month-old, "Liam," from the ER with a diagnosis of RSV bronchiolitis. He is tachypneic with a respiratory rate of 58, has audible wheezing, and you clearly see nasal flaring and subcostal retractions with each breath. He is fussy but lethargic between cries.
Nursing Intervention Strategy:
Immediate Action (First 1-2 minutes): Elevate the head of the crib to a semi-Fowler's position (30-45 degrees). Perform a quick focused respiratory assessment: count respirations for a full minute, listen to lung sounds, observe color, and check pulse oximetry. This is your priority.
Oxygen & Monitoring: If SpO2 is below 92%, apply humidified oxygen as ordered via nasal cannula or hood. Continuously monitor vital signs and work of breathing.
Secretions Management: Use a bulb syringe or nasal aspirator to gently suction the nares before feeds and as needed to clear obstruction. Avoid deep or frequent suctioning which can cause mucosal trauma and edema.
Hydration & Nutrition: Assess for dehydration (dry mucous membranes, poor tear production, decreased urine output). Due to respiratory distress, the infant is likely NPO (nothing by mouth) or on IV fluids (e.g., D5 1/4 NS) to prevent aspiration and provide maintenance fluids. Offer small, frequent feeds by bottle or breast ONLY if respiratory status is stable and the infant can coordinate sucking, swallowing, and breathing.
Medication Administration: Administer medications as ordered, which may include nebulized hypertonic saline (to loosen secretions) or a bronchodilator trial. Antipyretics (e.g., acetaminophen) for fever. Document response.
Patient Safety and Precautions:
Key Point!ISOLATION PRECAUTIONS: RSV is highly contagious. Place the infant on Contact Precautions (gown & gloves) and consider droplet precautions in some protocols. Meticulous hand hygiene is critical.
Avoid Overstimulation: Cluster care to allow for rest. A crying, agitated infant has increased oxygen demand and can worsen respiratory distress.
Monitor for Deterioration: Signs of impending respiratory failure include lethargy, cyanosis, apnea, and inability to maintain SpO2 despite oxygen. Be prepared for possible transfer to PICU (Pediatric Intensive Care Unit).
Nursing Procedure & Medication FlowPositioning Procedure: 1. Ensure crib side rails are up. 2. Use a folded blanket or a commercial wedge under the head of the mattress to achieve a 30-45 degree incline. 3. Position the infant on their back or side, ensuring the neck is in a neutral, sniffing position to keep the airway open. 4. Never use pillows or loose bedding due to SIDS (Sudden Infant Death Syndrome) risk.
Medication Caution: If giving a nebulized bronchodilator (e.g., albuterol), monitor for tachycardia, tremors, and worsening restlessness as side effects. Assess lung sounds before and after treatment to evaluate effectiveness.
A Word from Your Senior Nurse
"In the whirlwind of a busy pediatric floor, seeing an infant work that hard to breathe is scary—for the parents and for you. Your first instinct might be to run for a medication or call the doctor, but never underestimate the power of a simple, correct position. Getting that head elevated is like giving a drowning person a life raft—it provides immediate, crucial support. In pediatrics, your assessment skills are everything. Those retractions are your patient telling you they're in trouble. Listen with your eyes, act with your hands (to position and comfort), and think with your ABCs. This mindset will guide you safely through countless NCLEX questions and, more importantly, through those critical first moments at the bedside."
