Therapeutic management of most children with Hirschsprung's disease is primarily

The correct answer is choice C. Asthma.

Choice A rationale:

A foreign body in the trachea can cause acute respiratory distress and a sudden cough, but it is unlikely to cause chronic nonproductive cough and diffuse wheezing during the expiratory phase of respiration. The symptoms in the scenario are more suggestive of a chronic condition.

Choice B rationale:

Bronchiolitis primarily affects infants and young children, causing symptoms such as fever, rhinorrhea, and wheezing. While wheezing can be present, the diffuse wheezing during the expiratory phase described in the scenario is more characteristic of asthma.

Choice C rationale:

Asthma is characterized by chronic inflammation of the airways, leading to episodes of bronchoconstriction and increased airway reactivity. The chronic, nonproductive cough and diffuse wheezing during the expiratory phase are classic signs of asthma. Expiratory phase wheezing occurs due to the narrowing of the smaller airways during expiration.

Choice D rationale:

Pneumonia is an infection of the lung tissue and can cause productive cough, fever, and crackles on auscultation. While wheezing might occur in pneumonia due to inflammation and narrowing of the airways, it's not the most likely cause of the symptoms described in the scenario.

The correct answers are choices A and E: Institute cluster care to encourage adequate rest and Place on noninvasive oxygen monitoring.

Choice A rationale:

Institute cluster care to encourage adequate rest. This is a correct choice. Cluster care involves grouping nursing interventions together to minimize disruptions to the child's rest. Adequate rest is crucial for the healing process in infants with respiratory syncytial virus (RSV) bronchiolitis.

Choice B rationale:

Administer cough syrup. This choice is incorrect for RSV bronchiolitis. Cough syrup is not recommended for infants with bronchiolitis. RSV primarily affects the lower respiratory tract and can cause airway inflammation, making cough syrup potentially ineffective and unnecessary.

Choice C rationale:

Administer antibiotics. This choice is incorrect for RSV bronchiolitis. RSV is a viral infection, and antibiotics are ineffective against viruses. Antibiotics should only be used when there is a bacterial infection or a clear indication.

Choice D rationale:

Encourage infant to drink 8 ounces of formula every 4 hours. This choice is not the best approach for managing RSV bronchiolitis. Infants with RSV may experience decreased appetite due to respiratory distress. Smaller, more frequent feedings are often recommended to prevent overfeeding and aspiration.

Choice E rationale:

Place on noninvasive oxygen monitoring. This is a correct choice. RSV bronchiolitis can cause respiratory distress and compromise oxygenation. Noninvasive oxygen monitoring helps assess the child's oxygen levels and aids in determining the need for supplemental oxygen therapy.
