It also helps in clearing up mucus, microbes, and fluids and irritant that could be affecting the breathing system. However, a cough can turn out to be a manifestation of an ailment if it persistence. There are usually two types of cough ailments, which are acute cough and chronic cough if it has lasted for more than four weeks. For a doctor examining a patient suffering from cough, the following questions needs to be asked and physical examinations carried out:

• For how long have you been coughing?
• Do you cough persistently or episodic
• Is the cough seasonal or perennial?
• Is your cough dry or productive

The physical examination involves taking the body temperature of a patient in order to determine if there is fever. Additionally, head and neck examination needs to be carried out to determine the state of nasal turbinate such as pale, inflamed or boggy (Goroll, 2010). The diagnostic tests to be carried out are determined by the interview carried out by the doctor. For instance, most patients are recommended to receive a chest X-ray to determine the problem (Taylor, 2013). If the chest X-ray fails to help identify the problem, the physician can recommend for other diagnostic test.

For instance, if the patients depict symptoms for pneumonia, chest radiography can be taken. Such symptoms include hypoxia, decreased breath sounds and crackles. The list of cough differentials includes; rhinitis caused by physical or chemical irritants, bacterial sinusitis, occupational rhinitis and allergic fungal sinusitis.
