,1. A nurse is assessing a client who is at risk for developing anemia. The nurse
reviews the client’s medical history, nutritional status, age, and recent health
events to identify factors that may reduce red blood cell production or increase red
blood cell loss. Which factors should the nurse recognize as risk factors for anemia?
Correct answer: Acute or chronic blood loss, increased hemolysis, inadequate
dietary intake or malabsorption, bone marrow suppression, and advanced age.
Rationale: Acute or chronic blood loss decreases the number of circulating red
blood cells and can eventually deplete iron stores needed for erythropoiesis.
Increased hemolysis causes red blood cells to be destroyed faster than the bone
marrow can replace them. Inadequate dietary intake or malabsorption can prevent
sufficient iron, vitamin B12, or folate from being available for normal red blood cell
production. Bone marrow suppression reduces the production of new blood cells,
while aging is associated with increased susceptibility to several conditions that can
contribute to anemia.
2. A client asks the nurse why hemoglobin is essential for normal body function.
The nurse explains that hemoglobin is a protein contained within red blood cells
and is responsible for transporting respiratory gases throughout the body. What is
the primary function of hemoglobin?
Correct answer: Hemoglobin carries oxygen from the lungs to the body’s tissues
and returns carbon dioxide from the tissues to the lungs. It also helps maintain the
shape of red blood cells.
Rationale: Hemoglobin binds oxygen in the lungs and transports it through the
bloodstream to tissues where oxygen is needed for cellular metabolism. It also
participates in transporting carbon dioxide from tissues back toward the lungs for
elimination. In addition to its role in gas transport, hemoglobin contributes to the
normal structure and shape of red blood cells. Adequate hemoglobin is therefore
essential for effective oxygen delivery and normal red blood cell function.
,3. A nurse is evaluating a client who reports fatigue, weakness, and reduced
exercise tolerance. Laboratory testing indicates that the client has anemia, and the
nurse reviews possible mechanisms responsible for the condition. What are the
three major causes of anemia?
Correct answer: Impaired red blood cell production, excessive blood loss, and
increased red blood cell destruction.
Rationale: Anemia can develop when the bone marrow does not produce enough
red blood cells to meet the body’s needs. Excessive blood loss can rapidly or
gradually reduce the circulating red blood cell mass. Increased red blood cell
destruction, also called hemolysis, causes cells to be removed from circulation
prematurely. These three mechanisms represent the major pathways through which
anemia develops.
4. A client is being evaluated for anemia, and laboratory findings suggest that red
blood cells are being destroyed more rapidly than they are being replaced. The
nurse recognizes that the client’s condition involves premature removal of
circulating erythrocytes. What type of anemia is characterized by premature
destruction of red blood cells?
Correct answer: Hemolytic anemia.
Rationale: Hemolytic anemia occurs when red blood cells are destroyed
prematurely, shortening their normal life span. The bone marrow may increase red
blood cell production to compensate for the accelerated destruction, but
compensation may become inadequate when hemolysis is significant. The resulting
reduction in circulating red blood cells can produce symptoms such as fatigue,
weakness, and pallor. Hemolysis may occur because of immune, infectious,
transfusion-related, medication-related, or other causes.
5. A hospitalized client develops signs of anemia after experiencing a condition
known to cause accelerated destruction of red blood cells. The nurse reviews the
, client’s history for conditions that can trigger hemolysis. What are common causes
of hemolytic anemia?
Correct answer: Infection and transfusion reactions.
Rationale: Certain infections can damage or destroy red blood cells and contribute
to hemolytic anemia. An incompatible blood transfusion can cause an immune-
mediated reaction in which the recipient’s antibodies attack transfused red blood
cells. Both conditions can result in rapid red blood cell destruction and clinical
manifestations of hemolysis. Prompt recognition is important because significant
hemolysis can compromise oxygen-carrying capacity and cause serious
complications.
6. A newborn develops anemia after birth, and the healthcare team suspects that
maternal and fetal blood types were incompatible. In another client, laboratory
findings suggest that the immune system is destroying the client’s own red blood
cells. The nurse reviews several mechanisms that can produce hemolysis. What are
the recognized causes of hemolytic anemia?
Correct answer: Infection, transfusion reaction, hemolytic disease of the
newborn caused by Rh incompatibility, autoimmune reaction, and drug-induced
hemolysis.
Rationale: Hemolytic anemia can occur when infectious processes directly or
indirectly damage red blood cells. An incompatible transfusion can trigger an
immune response that destroys transfused erythrocytes. Rh incompatibility can
cause maternal antibodies to attack fetal or newborn red blood cells, producing
hemolytic disease of the newborn. Autoimmune reactions and certain medications
can also cause antibodies or other mechanisms to promote premature red blood cell
destruction.
7. A client undergoes a gastrectomy and later develops laboratory findings
consistent with vitamin B12 deficiency and anemia. The nurse explains that the
