Answer 1

1. Describe the incidence of lung cancer.

Answer:The occurrance of cancer to the people in the particular period of time around specific recorded numbers are termed as Incidence of lung cancer.Lung cancer is the second most common cancer in both men and women. About 234,030 new cases of lung cancer .About 154,050 deaths from lung cancer (83,550 in men and 70,500 in women).

2. Explain why wheezing, hemoptysis, and pleural effusion may occur may occur in patients with lung cancer.

Answer:Wheezing or hoarseness may signal blockage or inflammation in the lungs that may go along with cancer. Hemoptysis can occur as a result of tumor erosion of a blood vessel.Pleural effusion can be caused by cancer cells spreading to the pleura. It can also develop if cancer cells block or change the flow of lymph fluid in the pleural cavity.

3.Explain the result of aspirating food and explain why the problem may be difficult to identify.

Answer:If the reflexes fail to clear the material, it may become in and obstruct the trachea causing choking. If we don't choke, food goes down the trachea and then to your lungs which lead to a very serious pneumonia and the problem may be difficult to identify because

*Healthcare provider will ask about medical history and symptoms that will be done by a speech-language pathologist (SLP). The SLP will try to find out if problem with the lower or upper part of your swallowing muscles.

*May have a physical exam which include an examination of your teeth, lips, jaws, tongue, and cheeks where they willask  to move these areas in certain ways and make certain sounds.

• Modified barium swallow test (MBS). This can show if material is going into your lungs.
• Fiber-optic endoscopic evaluation of swallowing (FEES). This can also show if material is going into your lungs.
• Pharyngeal manometry. This checks the pressure inside your esophagus.

By completing all these tests it takes suffiecent time and conformations becomes less.

4. Explain how obstruction develops in an asthmatic patient following exposure to an inhaled allergen.

Answer: Asthma exacerbations include allergen exposure in sensitized individuals, viral infections, exercise, irritants, ingestion of nonsteroidal anti-inflammatory agents. Exacerbating factors can include one or all of these exposures.

5. Compare the effects of partial and total obstruction of the airway on ventilation and on oxygen levels in the blood.

Answer:The paercentage of oxygen levels presence in the blood varies from both partial and total obstruction because of the flow of air which is obligated due to some conditions depended on patient.Whereas,the partial obstruction have a percentage below 86% and total obstruction is below 75%.
