Question

Which disease process or disorder is caused by irregularly formed and abnormally shaped erythrocytes that lead to a poor supply of oxygen in the client’s body?

Answers

  1. Anemia
    • Rationale:

      Anemia is defined as a blood abnormality caused by an inadequate supply of certain circulating blood cells, usually erythrocytes (i.e., red blood cells).

  2. Hemophilia
    • Rationale:

      Hemophilia is a medical condition in which the ability of the client’s blood to clot is reduced leading to hemorrhage from even a mild injury.

  3. Sickle cell disease
    • Rationale:

      Sickle cell disease is an inherited group of disorders which cause the individual’s red blood cells to contort into a sickle shape impacting oxygenation throughout the circulatory system.

  4. Clotting factor disorder
    • Rationale:

      A clotting factor disorder causes issues with coagulation and can be caused by a lack of platelets or clotting factors.

Overview

Hematologic diseases are disorders of the blood and/or the blood-forming organs of the human body.

Explanation

Learning Outcomes

There are many disease processes that affect the hematologic system within the human body. These conditions include anemia, blood cell cancers, complications from chemotherapy or transfusions, conditions related to HIV, genetic disorders, and sickle cell disease. Sickle cell disease is caused by irregularly formed and abnormally shaped (e.g., sickle-shaped) erythrocytes that lead to a poor supply of oxygen in the client’s body.
