, Explanation: Cancer confined to the organ of origin is stage 1; cancer that is locally
invasive is stage 2; cancer that has spread to regional structures, such as
the lymph nodes, is stage 3; and cancer that has spread to distant sites,
such as a liver cancer spreading to the lung or a prostate cancer spreading
to bone, is stage 4.
Question 4. Erythrocyte life span of less than 120 days, ineffective bone
marrow response to erythropoietin, and altered iron metabolism
describe the pathophysiologic characteristics of which type of
anemia?
Aplastic
Sideroblastic
Anemia of chronic disease
Iron deficiency
Explanation: Anemia of chronic disease results from a combination of (1) decreased
erythrocyte life span, (2) suppressed production of erythropoietin, (3)
ineffective bone marrow erythroid progenitor response to erythropoietin,
, and (4) altered iron metabolism and iron sequestration in macrophages. This
result is not true of the other options.
Question 5. When an individual aspirates food particles, where would the
nurse expect to hear decreased or absent breath sounds?
Left lung
Right lung
Trachea
Carina
Explanation: The right mainstem bronchus extends from the trachea more vertically than
the left main bronchus; therefore aspirated fluids or foreign particles tend to
enter the right lung rather than the left or any of the other locations listed.
Question 6. What is the first stage in the infectious process?
