RSV / Bronchiolitis

NCLEX Review Guide: Pediatric Infectious Diseases - RSV/Bronchiolitis

Respiratory Syncytial Virus (RSV) & Bronchiolitis

RSV Pathophysiology & Risk Factors

  • RSV is the most common cause of bronchiolitis in infants under 2 years, causing inflammation and obstruction of the small airways (bronchioles).
  • Peak incidence occurs between 2-6 months of age, with highest risk in premature infants, immunocompromised children, and those with congenital heart disease.
  • The virus causes bronchiolar edema, mucus production, and cellular debris that obstructs airflow, leading to air trapping and atelectasis.

Memory Aid: RSV Risk Factors

"PREEMIE"
P - Premature birth
R - Respiratory conditions
E - Exposure to smoke
E - Early age (under 6 months)
M - Male gender
I - Immunocompromised
E - Environmental crowding

Clinical Manifestations

  • Initial symptoms mimic a common cold with rhinorrhea, low-grade fever, and cough that progresses over 2-3 days.
  • Classic signs include expiratory wheeze, prolonged expiratory phase, and fine crackles on auscultation.
  • Severe cases present with retractions, nasal flaring, cyanosis, and feeding difficulties due to increased work of breathing.
  • Apnea episodes may occur, especially in infants under 6 months or those born prematurely.

Clinical Scenario

A 4-month-old infant presents with 3 days of runny nose and cough. Today, parents report difficulty feeding, increased irritability, and "noisy breathing." On assessment: RR 65, mild retractions, expiratory wheeze, and oxygen saturation 92% on room air. This presentation is classic for RSV bronchiolitis requiring immediate intervention.

Nursing Assessment & Monitoring

  1. Assess respiratory status every 2-4 hours: rate, effort, oxygen saturation, and breath sounds.
  2. Monitor for signs of respiratory distress: retractions, nasal flaring, head bobbing, and cyanosis.
  3. Evaluate feeding tolerance and hydration status as infants may refuse feeds due to respiratory distress.
  4. Document apnea episodes and bradycardia, particularly in high-risk infants requiring continuous monitoring.

Key Assessment Points

  • Oxygen saturation <92% indicates need for supplemental oxygen
  • Inability to feed or decreased urine output suggests dehydration
  • Lethargy or irritability may indicate hypoxemia or CO2 retention

Treatment & Nursing Interventions

  • Supportive care is the mainstay of treatment including oxygen therapy, hydration, and nutrition support.
  • Administer humidified oxygen to maintain oxygen saturation >92% and reduce airway irritation.
  • Provide frequent small feedings or IV fluids if oral intake is compromised due to respiratory distress.
  • Avoid routine use of bronchodilators, corticosteroids, or antibiotics as they are not effective for viral bronchiolitis.

RSV Treatment: Do's vs Don'ts

APPROPRIATEAVOID
Humidified oxygenRoutine bronchodilators
Supportive careCorticosteroids
Adequate hydrationAntibiotics (unless bacterial co-infection)
Suctioning PRNCough suppressants

Prevention & Discharge Planning

  • Palivizumab (Synagis) prophylaxis is recommended for high-risk infants during RSV season (October-March).
  • Educate families on strict hand hygiene, avoiding crowds, and keeping infants away from sick contacts.
  • Teach parents to recognize signs of respiratory distress and when to seek immediate medical attention.
  • Emphasize that symptoms typically worsen for 3-5 days before gradually improving over 1-2 weeks.

Discharge Teaching: "BREATHE"

B - Breathing changes (watch for worsening)
R - Rest and adequate sleep
E - Eating difficulties (small, frequent feeds)
A - Avoid smoke and crowds
T - Temperature monitoring
H - Hand hygiene crucial
E - Emergency signs: blue lips, severe retractions

Commonly Confused Points

RSV vs Other Respiratory Conditions

ConditionAge GroupKey FeaturesTreatment
RSV BronchiolitisUnder 2 yearsExpiratory wheeze, fine cracklesSupportive care only
AsthmaUsually >2 yearsReversible airway obstructionBronchodilators effective
PneumoniaAny ageFever, localized cracklesAntibiotics if bacterial
Croup6 months-6 yearsBarking cough, stridorCorticosteroids helpful

Common Pitfalls

  • Don't assume all wheezing in infants is asthma - RSV is more likely under age 2
  • Avoid giving bronchodilators routinely - they're not effective for RSV
  • Don't overlook feeding difficulties as a sign of respiratory distress

Study Tips & Quick Checks

NCLEX Success Strategy

Remember: RSV = SUPPORT
S - Supportive care primary treatment
U - Under 2 years most affected
P - Prevent with hand hygiene
P - Palivizumab for high-risk infants
O - Oxygen therapy as needed
R - Respiratory monitoring essential
T - Teaching family about progression
