A client is receiving epoetin alfa therapy as part of the management of anemia. The nurse should monitor the client for which potential side effect of this medication?
A.
Hypertension
B.
Hyperkalemia
C.
Hypoglycemia
D.
Hypocalcemia
The Correct Answer and Explanation is:
The correct answer is A. Hypertension.
Explanation
Epoetin alfa is a synthetic form of erythropoietin, a hormone that stimulates the production of red blood cells (RBCs) in the bone marrow. It is commonly used in the management of anemia, particularly in patients with chronic kidney disease, those undergoing chemotherapy, or patients with certain other conditions that lead to decreased erythropoiesis.
One of the significant side effects of epoetin alfa therapy is hypertension. This occurs because the increase in red blood cell mass can lead to an increase in blood viscosity, which in turn can raise blood pressure. The risk of developing hypertension is particularly pronounced in patients with preexisting hypertension or those who have other risk factors for cardiovascular disease. Therefore, it is essential for healthcare providers to closely monitor blood pressure in patients receiving epoetin alfa therapy.
In clinical practice, it is recommended that blood pressure be assessed regularly, and if hypertension develops, it may require the initiation of antihypertensive medication. The dosage of epoetin alfa may also need to be adjusted based on the patient’s hemoglobin levels and response to therapy, ensuring that hemoglobin levels do not rise too quickly or exceed the target range (typically around 11-12 g/dL).
Other side effects of epoetin alfa, while relevant, are less commonly linked to this therapy. For instance, hyperkalemia (B), hypoglycemia (C), and hypocalcemia (D) are not typical side effects associated with epoetin alfa. Hyperkalemia can occur in patients with renal impairment but is not a direct effect of the medication. Hypoglycemia is related to insulin and glucose management, while hypocalcemia typically pertains to parathyroid hormone regulation and is unrelated to erythropoiesis.
In summary, due to the mechanism of action of epoetin alfa and its effect on blood viscosity, hypertension is a primary concern that requires monitoring and management during therapy.
