A client on hemodialysis is prescribed erythropoietin-stimulating agents (ESAs) to manage anemia. Which of the following laboratory values should the nurse monitor closely during ESA therapy?

A) This statement is incorrect. Serum calcium levels are not directly related to ESA therapy for anemia management. ESA therapy focuses on increasing red blood cell production.

B) This statement is incorrect. Blood urea nitrogen (BUN) levels are indicators of kidney function and may be monitored for other reasons in a client on hemodialysis. However, they are not directly related to ESA therapy for anemia management.

C) This statement is accurate. During ESA therapy, the nurse should closely monitor the client's hemoglobin and hematocrit levels. ESAs stimulate the production of red blood cells and can increase hemoglobin and hematocrit levels. Regular monitoring is essential to prevent anemia or excessive increases in these values.

D) This statement is incorrect. Serum potassium levels may be monitored for a client on hemodialysis due to the potential for electrolyte imbalances, but they are not the primary concern during ESA therapy for anemia management.

A. Incorrect. Offering hard candies or mints may provide temporary relief from the metallic taste, but it does not address the underlying cause.

B. Correct. A persistent metallic taste in the mouth can be caused by various factors, such as dietary changes, medication side effects, or biochemical imbalances. Assessing the client's recent dietary and medication changes can help identify the potential cause.

C. Incorrect. Providing an oral rinse may offer temporary relief, but it does not address the underlying cause of the metallic taste.

D. Incorrect. Administering an antiemetic medication is not indicated for a metallic taste in the mouth, as it is not associated with nausea or vomiting.
