NR 507 Final Exam Study Guide – Normocytic
Anemias & Hemoglobinopathies
Normocytic Anemias - ANS -- 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? - ANS -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? - ANS -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? - ANS -50 year old client who had a blood transfusion reaction
Rationale:
A client who experienced a transfusion reaction after a blood transfusion is at significant risk for
developing hemolytic anemia. Transfusion reactions can involve the destruction of donor red
blood cells, leading to hemolysis and associated symptoms such as fever, chills, and jaundice.
Iron-deficiency anemia is characterized by a lack of iron to produce hemoglobin. It does not
inherently predispose individuals to hemolytic anemia.
Thalassemia is a genetic disorder affecting the production of hemoglobin but does not directly
lead to hemolysis of red blood cells, a key feature of hemolytic anemia.
Excessive blood loss from surgery can lead to hypovolemic anemia but does not inherently
cause hemolysis.
Pathophysiology of Normocytic Anemias - ANS -- Normocytic anemias are characterized by the
presence of normal-sized red blood cells. The red blood cells of normocytic anemias have a
mean corpuscular volume (MCV) of 80-99 dL. When a client presents with normocytic anemia, a
reticulocyte count should be performed to assess the number of immature red blood cells in the
