Exophthalmos may occur in children with what diagnosis?

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 answer is choice C.

Choice C rationale:

Placing the avulsed tooth in cold milk is the most suitable medium for transporting it to the dentist. Cold milk helps preserve the viability of the tooth's cells and tissues, which is crucial for successful reimplantation. The temperature and composition of cold milk provide a suitable environment to prevent cell damage.

Choice A rationale:

Placing the tooth in a dry, clean jar is not recommended. A dry environment can cause the tooth's cells to dry out and become nonviable, making reimplantation less successful.

Choice B rationale:

Warm salt water is not the optimal choice for transporting an avulsed tooth. Warm water can cause damage to the tooth's cells, and salt water may not provide the necessary conditions to maintain the tooth's viability.

Choice D rationale:

Placing the tooth in cold water might seem logical, but it is not as effective as cold milk. Cold water lacks the protective properties and nutrients that milk provides, potentially leading to a higher risk of cell damage in the avulsed tooth.
