Which of the following clinical findings is NOT characteristic of asthma?

Cough that is congested and worse during the day does not align with the typical patterns seen in asthma. Asthma is characterized primarily by symptoms that tend to manifest or worsen during the night and early morning. Patients often experience nighttime coughing, which can disrupt sleep, and this is a hallmark feature of the condition.

In contrast, coughs associated with asthma are usually dry, non-productive, and can be triggered or exacerbated by physical activity or exposure to allergens and irritants. The recurrent shortness of breath, nighttime cough, and wheezing are all classic symptoms that indicate the presence of asthma or an asthma exacerbation, particularly in the context of respiratory infections.

The other options reflect typical symptoms of asthma. Nighttime coughing is especially indicative, as is the recurrent shortness of breath and wheezing, which often occurs during respiratory infections. Recognizing these distinctions is crucial for effective management and diagnosis.
