Which of the following respiratory conditions in children over 2 years old has similar lung sounds to an infant who has bronchiolitis?

The correct choice is asthma, as it can produce respiratory sounds similar to those heard in infants with bronchiolitis, particularly wheezing. In both cases, the underlying airway obstruction leads to turbulent airflow, which produces the characteristic wheezing sound.

In children with asthma, inflammation and constriction of the airways can occur, resulting in symptoms that may overlap with those of bronchiolitis, including wheezing and difficulty breathing. This similarity in lung sounds is crucial for recognition and management, as both conditions may necessitate bronchodilator therapy.

Pulmonary edema, while it can sometimes produce crackles or rales, does not typically present with wheezing as a primary sound. Pertussis, also known as whooping cough, may include a whooping sound during coughing fits but does not share the wheezing characteristic associated with bronchiolitis and asthma. Pneumonia can lead to various lung sounds, including crackles or diminished sounds but does not necessarily produce the wheezing associated with bronchial constriction and obstruction seen in both asthma and bronchiolitis.
