Attempting to calm the infant by placing him in his mother's lap and offering him a bottle is unsafe: infants in respiratory distress cannot coordinate sucking, swallowing, and breathing. A bottle increases risk of aspiration and worsens hypoxia.

Alerting the physician to the situation and asking for an order for a stat chest radiograph delays immediate, lifesaving interventions. A chest X-ray may confirm diagnosis but is not priority in acute distress.

Bring the emergency equipment to the room and beginning bag-valve-mask ventilation is appropriate for respiratory arrest, not initial distress when the infant is still breathing spontaneously. The infant first needs airway clearance and oxygen.

Hepatitis B immune globulin is given to newborns of mothers positive for HBsAg, not specifically to preterm infants for RSV prevention.

Pulmozyme (dornase alfa) is a mucolytic used in cystic fibrosis to thin pulmonary secretions, not for RSV prophylaxis.

Varicella-zoster immune globulin is given to high-risk, non-immune children after exposure to chickenpox, not routinely for preterm infants.

RSV is most common in late fall, winter, and early spring and is not more prevalent in the summer. This is because lower temperatures help RSV survive longer on surfaces and in the air. Reduced humidity also allows respiratory droplets to linger and travel farther, increasing transmission. Furthermore, indoor crowding during colder months in schools, daycare, and family gatherings boosts close contact and viral spread.

RSV primarily affects infants and young children under 2 years, especially preterm infants or those with chronic illness.

RSV is highly contagious and spreads easily via droplets, secretions, and contact with contaminated surfaces.

Gloves only is insufficient for RSV prevention. RSV spreads via large droplets and surfaces, requiring gown and mask in addition to gloves.

RSV is very contagious and is a major cause of hospitalization in infants during winter months.

Proper hand washing between clients is essential but not enough on its own. RSV requires contact and droplet precautions in addition to hand hygiene.

Blood test is not diagnostic for RSV. Blood may show leukocytosis or other nonspecific findings but cannot confirm RSV.

Sputum culture is not reliable since young infants rarely produce sputum. Furthermore, sputum cultures are used for bacterial infections, not RSV.

Throat culture detects bacterial pathogens like streptococcus not RSV which requires nasopharyngeal washings for diagnosis.

A 2-month-old child managed at home: While young age increases risk, a healthy infant at home is less vulnerable than one with BPD.

A 3-month-old child requiring low-flow oxygen: Oxygen dependence suggests chronic illness, but the greatest risk here is specifically linked to bronchopulmonary dysplasia or congenital heart disease.

A 2-year-old child: RSV risk decreases as children get older hence severe RSV is far less common after age 2.

Aminophylline is a bronchodilator used for asthma or apnea of prematurity, not for RSV prevention.

Bronchodilators may be used in treatment for wheezing but do not prevent RSV.

Corticosteroids are not effective for preventing or treating RSV. It may actually suppress immune response.

Blood levels every 4 hours are invasive and not necessary unless severe dehydration or electrolyte imbalance is suspected.

Urinalysis every 8 hours can detect concentration changes, but it is not a routine or practical method for monitoring hydration.

Weighing each diaper is part of I&O measurement, but on their own they don’t provide a full hydration picture.

Imbalanced nutrition: More than body requirements is not inaccurate. Infants with bronchiolitis typically have decreased intake, not excess.

Deficient diversional activity is not a priority in acute illness hence safety and survival come first.

While isolation precautions are used for RSV, this is not the priority diagnosis compared to respiratory compromise.

Placing the child in a prone position for comfort is incorrect. Infants should be placed supine for sleep to reduce SIDS risk.

Using warm mist to replace insensible fluid loss is not recommended since mist therapy does not prevent dehydration and may increase infection risk. Fluids should be given orally or IV if necessary.

Engaging the child in many activities to prevent developmental delay is not appropriate during acute illness. The child needs rest and supportive care.
