How would you treat a patient with possible chronic respiratory disease who present with 1 day hx congestion,clear sputum, afebrile, no sob, or rales?

More evaluation: Patient may be suffering from allergic rhinitis. Send to an allergist or send for blood testing for IgE to environ triggers like dust mite, cockroach, tree pollen etc. Also start intranasal steroid spray (if no contraindications- nose bleeds or increased intraoccular pressure) because that will help with both allergic and non allergic rhinitis and also use decongestant - sudafed (if no htn).

Agree with Dr Gupta: ...with comments: need to determine any cause of chronic respiratory disease (asthma? copd?). Asthma can certainly be exacerbated by environmental allergies, which can also trigger allergic rhinitis (nasal itching/congestion, sneezing, drainage). Both cause cough. As an initial test, blood tests for allergies poorly predict allergy sensitivity compared to skin testing and symptom history.
