61 year?old man presents to OPD with complaints of persistent, non-productive cough for 1 month. He has no other symptom. He is smoking around 20 biddis per day for last 25 years. Physical examination is normal. What is the line of management in such patients?

**Core Concept**
The patient's presentation of a persistent, non-productive cough in a long-term smoker suggests chronic bronchitis, a type of chronic obstructive pulmonary disease (COPD). The patient's history of smoking, particularly the high number of biddis consumed daily for 25 years, significantly increases his risk of developing COPD.

**Why the Correct Answer is Right**
The management of chronic bronchitis/COPD involves addressing the underlying airway inflammation, improving lung function, and reducing symptoms. The primary goal is to reduce the patient's smoking habit, as this is the most effective way to prevent further lung damage and slow disease progression. The patient should also be educated about the importance of pulmonary rehabilitation, including regular exercise and bronchodilator therapy to manage symptoms. In this case, the correct answer likely refers to **counseling to quit smoking**.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not address the patient's underlying condition. While antibiotics may be used to treat acute exacerbations of COPD, they are not a primary treatment for chronic bronchitis.

**Option B:** This option is incorrect as it does not address the patient's smoking habit, which is the primary contributor to COPD. While bronchodilators may be used to manage symptoms, they do not address the underlying cause of the disease.

**Option C:** This option is incorrect as it does not address the patient's need for smoking cessation. While pulmonary rehabilitation is an important component of COPD management, it is not the primary line of management in this case.

**Option D:** This option is incorrect as it does not address the patient's underlying condition. While corticosteroids may be used to treat acute exacerbations of COPD, they are not a primary treatment for chronic bronchitis.

**Clinical Pearl / High-Yield Fact**
Smoking cessation is the most effective way to prevent further lung damage and slow disease progression in patients with COPD. Patients should be encouraged to quit smoking and offered support and resources to help them achieve this goal.

**Correct Answer: C. Pulmonary rehabilitation and bronchodilators.

✓ Correct Answer: C. Do a chest X ray and refer him to smoking cessation clinic
