Assessment

Primary Diagnosis: Acute Bronchial Asthma Exacerbation (J45.9)

Secondary Concerns:

Possible underlying COPD given age and environmental exposures
Hypertension (elevated blood pressure reading)
Environmental respiratory irritant exposure

Differential Diagnoses

Acute Bronchial Asthma Exacerbation: Classic presentation of worsening respiratory symptoms in recently diagnosed asthmatic patient with nocturnal dyspnea, productive cough, and chest tightness. The temporal relationship between recent asthma diagnosis and current exacerbation, combined with environmental risk factors, supports this diagnosis.

COPD Exacerbation: Given patient’s age (63), environmental exposure to factory pollutants, and presentation with progressive dyspnea and productive cough, COPD should be considered as either primary diagnosis or comorbid condition.

Pneumonia: Can present with dyspnea, productive cough, and chest discomfort. However, absence of fever and acute onset pattern makes this less likely.

Heart Failure: Elevated blood pressure and heart rate could suggest cardiovascular involvement, but primary respiratory symptoms point toward pulmonary etiology.

Pulmonary Embolism: Acute dyspnea and chest pain could suggest PE, but gradual onset over one week and response pattern make this less likely.

Most Likely Diagnosis: Acute Bronchial Asthma evidenced by progressive respiratory symptoms following recent asthma diagnosis, nocturnal dyspnea pattern, productive cough, and chest tightness in patient with environmental risk factors.
