Which assessment data indicates the desired outcome of epoetin alfa therapy?

• A. Hemoglobin level increases.
• B. Hematocrit increases.
• C. Conjunctival sacs redden.
• D. Conjunctival sac returns to reddish-pink color.

Answer: (D)

Epoetin alfa works by boosting red blood cell production to improve oxygen delivery to tissues. The most practical bedside sign that the therapy is working is the color of the conjunctival sacs: when pallor from anemia improves, these membranes return to a reddish-pink color, indicating better perfusion and higher hemoglobin levels. While laboratory values like hemoglobin and hematocrit will rise with continued treatment, the visible change in conjunctival color provides a direct, immediate assessment of improved oxygen-carrying capacity. Reddened conjunctiva due to irritation would not reflect a positive response to therapy, so the reddish-pink conjunctival color best signals the desired outcome.
