Which laboratory result should a nurse review to determine the therapeutic effect of epoetin alfa?

The white blood cell count
The platelet count
The hematocrit (Hct)
The blood urea nitrogen (BUN)

The correct answer is: The hematocrit (Hct)

The nurse should review the hematocrit (Hct) to determine the therapeutic effect of epoetin alfa. Epoetin alfa is a medication used to stimulate red blood cell production in patients with anemia. By monitoring the hematocrit level, which reflects the percentage of red blood cells in the blood, the nurse can assess whether the medication is effectively increasing red blood cell count and improving the patient's anemia. Monitoring white blood cell count, platelet count, or blood urea nitrogen (BUN) levels would not directly reflect the therapeutic effect of epoetin alfa in treating anemia.
