We would tell Mr. Garvey that the normal cells in his lungs have been replaced by more mature cells within the epithelial lining because of damage caused by smoking. This process is called metaplasia (McCance & Huether, 2010). Stratified squamous epithelial cells are considered the thickest so they have formed to protect the bottom layer of his lung tissue. These type of cells are more conducive to constant friction and irritation that is caused by smoking. These mature cells lack the protection that the normal lung cells have which can produce mucus and have cilia that help move the mucus with its harmful substances out of the lungs and to the throat via a cough (McCance & Huether, 2010). We would strongly encourage Mr. Garvey to quit smoking now. We would explain that these changes are reversible if he stops smoking now. The cessation of smoking will remove the irritant and allow for the normal cells to return. One way to convince Mr. Garvey to stop smoking would be to tell him that lung cancer begins with “the transformation of one epithelial cell” (ACC Atlas of Pathophysiology, 2010). If he continues to smoke, instead of the cells returning back to their normal state, they may become irreversibly damaged and possibly become cancerous. We would also show him pictures of normal columnar ciliated epithelial cells and stratified squamous epithelial cells while we discuss this.

In 1970 only about 2.7 percent of registered nurses were men and as of 2011 that increased to 9 % (U.S.... [tags: Nursing, Nurse, Nursing school]
