Question

1) The optimal position for auscultation of bronchial sounds is over the xiphoid process of the sternum--------(true/ false)

2) A patient is rushed to hospital with a gunshot wound to the chest. upon arrival, the doctors discover that the patient is suffering from a collapsed right lung. explain why the lung collapsed when the bullet penetrated the patient's thoracic cavity.

3) Trace the pathway a molecule of oxygen must take to the nasal cavity to an alveolus in the inferior lobe of the right lung. be sure to name all the conducting and respiratory portion structures the molecule will pass through along the way.

Explanation / Answer

1.The statement is False

Reason: The optimal position for auscultation of bronchial sounds is over the trachea as at this position ,the sound produced is louder and with a higher pitch.

2.When the bullet penetrated the patients's thoracic cavity, there becomes a hole in the chest wall and outside air can enter in through that hole and gather around the lungs.When there occurs large amount of air outside of the lungs, the lungs fails to expand and the air tries to push on the outside of the lungs and makes it collapse.

3.The pathway would be as below:

nasal cavity -superior, inferior, and middle meatuses and conchaes-----internal nares---nasopharynx---oropharynx----laryngopharynx----larynx---glottis--vocal cord ----trachea---right primary bronchi----right secondary bronchi---right tertiary bronchi----right bronchioles-------right terminal bronchioles----right respiratory bronchioles-----right alveolar ducts----right aloveoli.
