Normocytic Anemias - ANSWERS-- Normocytic anemias are a group of blood
disorders characterized by a normal mean corpuscular volume (MCV)
- The most common types of normocytic anemias include anemia of chronic
disease and hemolytic anemia
A nurse practitioner (NP) evaluates a 45-year-old client who presents with fatigue
and weakness. The NP diagnoses the client with anemia of chronic disease. What
is the primary pathophysiological mechanism causing this normocytic anemia? -
ANSWERS-Defective erythropoiesis
Rationale:
The primary pathophysiological mechanism underlying normocytic anemias such
as anemia of chronic disease is defective erythropoiesis. Chronic inflammation
affects the bone marrow, leading to impaired production of red blood cells despite
adequate iron availability.
, Impaired iron absorption is more relevant to microcytic anemias, where the size of
red blood cells is reduced due to insufficient iron for hemoglobin synthesis.
Excessive blood loss typically results in hypovolemic anemia and can lead to
microcytic or normocytic anemia, depending on the rate of blood loss. However,
normocytic anemias are not primarily characterized by excessive blood loss.
Delayed maturation of erythrocyte precursors is a characteristic feature of
macrocytic anemias, not normocytic anemias
A nurse practitioner (NP) evaluates a 28-year-old client who presents with fatigue,
jaundice, and dark-colored urine. The NP diagnoses the client with hemolytic
anemia. What is the most likely pathophysiological mechanism causing this
normocytic anemia? - ANSWERS-Increased blood cell destruction
Rationale:
Hemolytic anemia is characterized by the premature destruction of red blood
cells, leading to the release of hemoglobin. The symptoms of fatigue, jaundice,
and dark-colored urine are classic manifestations of hemolysis.
Impaired iron absorption is more relevant to microcytic anemias, where the size of
red blood cells is reduced due to insufficient iron for hemoglobin synthesis.
Defective erythropoiesis involves abnormalities in the production of red blood
cells. While it can contribute to certain types of anemias, hemolytic anemia is
primarily characterized by the accelerated destruction of mature red blood cells.
Excessive blood loss, while a cause of anemia, typically leads to hypovolemic
anemia rather than hemolytic anemia.
Which client should the nurse practitioner (NP) recognize as most at risk for
developing hemolytic anemia? - ANSWERS-50 year old client who had a blood
transfusion reaction
