marrow response to erythropoietin, and altered iron metabolism
describe the pathophysiologic characteristics of which type of

Aplastic
Sideroblastic

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.

nurse expect to hear decreased or absent breath sounds?

Right lung
Trachea
