Questions: The nurse is planning to teach a patient with newly diagnosed chronic kidney disease (CKD). Which information about anemia and CKD should the nurse include? Anemia is common because of decreased production of erythropoietin.

The answer is the second one: Anemia is common because of decreased production of erythropoietin.

Explanation for each option:

1. Thrombocytopenia occurs as a result of an increase of erythropoietin.
   This statement is incorrect. Thrombocytopenia refers to a low platelet count, which is not directly related to erythropoietin levels. Erythropoietin primarily stimulates the production of red blood cells, not platelets.

2. Anemia is common because of decreased production of erythropoietin.
   This statement is correct. In chronic kidney disease, the kidneys are damaged and produce less erythropoietin, a hormone that stimulates red blood cell production in the bone marrow. This leads to anemia, which is a common complication of CKD.

3. The decreased release of renin contributes to the development of anemia.
   This statement is incorrect. Renin is involved in blood pressure regulation and the renin-angiotensin-aldosterone system, not directly in red blood cell production. Anemia in CKD is primarily due to decreased erythropoietin production, not renin.

4. Decreased erythropoietin can increase the risk of sickle cell disease.
   This statement is incorrect. Sickle cell disease is a genetic disorder unrelated to erythropoietin levels. Decreased erythropoietin leads to anemia, but it does not cause or increase the risk of sickle cell disease.

In summary, the correct information to include in teaching a patient with CKD about anemia is that it is common due to decreased production of erythropoietin.
