Ans: B
Feedback:
Treatment of secondary polycythemia focuses relief of the underlying hypoxia. Secondary polycythemia increases in the production of erythropoietin, hence an increased production of erythrocytes. A vitamin B12 deficiency does not underlie secondary hypoxia, and dialysis is not a relevant treatment option. Erythropoietin injections would exacerbate the client's polycythemia.
