A nurse is caring for a client with anemia who is experiencing fatigue and weakness. The nurse should recommend which activity to conserve energy and manage the symptoms?

A) This choice is incorrect because hemolytic anemia is characterized by an increased destruction of red blood cells, which would typically result in a high reticulocyte count.

B) This choice is incorrect because iron-deficiency anemia is characterized by a low level of iron, which leads to decreased hemoglobin production but does not necessarily affect reticulocyte count.

C) This choice is correct. Aplastic anemia is characterized by the failure of the bone marrow to produce an adequate number of red blood cells, leading to a low reticulocyte count.

D) This choice is incorrect because pernicious anemia is caused by a deficiency in vitamin B12, which affects red blood cell maturation but does not directly influence reticulocyte count.

A) This choice is correct. Serum ferritin levels are used to assess the body's iron stores. Ferritin is a protein that stores iron in the body, and low levels of serum ferritin indicate iron deficiency.

B) This choice is incorrect because the erythrocyte sedimentation rate (ESR) is a nonspecific indicator of inflammation and is not directly related to iron stores.

C) This choice is incorrect because total iron-binding capacity (TIBC) measures the amount of iron that can be bound to transferrin, a protein that transports iron in the blood, but it does not directly assess iron stores.

D) This choice is incorrect because the white blood cell count (WBC) is not directly related to iron stores or the evaluation of anemia.
