A nurse is caring for a client who has chronic renal disease and is receiving therapy with epoetin alfa.
Which of the following laboratory results should the nurse review for an indication of a therapeutic effect of the medication?
The hematocrit (Hct).
The erythrocyte sedimentation rate (ESR).
The platelet count.
The leukocyte count.
The Correct Answer is A
Choice A rationale
The hematocrit (Hct). This statement is correct. Epoetin alfa is used to treat anemia by stimulating the production of red blood cells. An increase in hematocrit levels indicates a therapeutic effect of the medication, as it reflects an increase in the proportion of red blood cells in the blood.
Choice B rationale
The erythrocyte sedimentation rate (ESR). This statement is incorrect. The ESR is a non- specific marker of inflammation and is not used to monitor the therapeutic effect of epoetin alfa. It does not provide information about red blood cell production or anemia.
Choice C rationale
The platelet count. This statement is incorrect. The platelet count measures the number of platelets in the blood, which are involved in clotting. It is not affected by epoetin alfa therapy and does not indicate the therapeutic effect of the medication.
Choice D rationale
The leukocyte count. This statement is incorrect. The leukocyte count measures the number of white blood cells in the blood, which are involved in the immune response. It is not affected by epoetin alfa therapy and does not indicate the therapeutic effect of the medication.

Explanation
Choice A rationale
Constant bubbling in the suction-control chamber is expected and indicates that the suction is functioning properly.
Choice B rationale
Bloody drainage in the collection chamber is expected in the immediate postoperative period and does not require intervention.
Choice C rationale
Fluid-level fluctuations in the water-seal chamber are normal and indicate that the system is functioning properly.
Choice D rationale
Continuous bubbling in the water-seal chamber indicates an air leak and requires intervention to prevent complications.
Correct Answer is B
Explanation
Choice A rationale
8 oz black tea is not recommended for clients with iron deficiency anemia as it contains tannins, which can inhibit iron absorption.
Choice B rationale
1 cup canned black beans is a good source of non-heme iron, which can help improve iron levels and alleviate fatigue associated with iron deficiency anemia.
Choice C rationale
8 oz whole milk is not a good source of iron and can interfere with the absorption of iron from other foods.
Choice D rationale
15 oz raisins contain some iron but are not as rich in iron as black beans. Additionally, the high sugar content in raisins may not be ideal for all clients.
