What is the primary cause of immunodeficiency disorders?
Environmental factors
Genetic or inherited defects
Autoimmune reactions
Excessive production of white blood cells
The Correct Answer is B
Explanation: The correct answer is b. Genetic or inherited defects. Immunodeficiency disorders are primarily caused by genetic mutations or defects that result in a weakened or impaired immune system.
Incorrect choices:
a. While environmental factors can contribute to the development of secondary immunodeficiency disorders, they are not the primary cause of most immunodeficiency disorders.
c. Autoimmune reactions are not the primary cause of immunodeficiency disorders. Autoimmune disorders involve the immune system attacking the body's own tissues, not a deficiency in the immune system.
d. Excessive production of white blood cells is not the primary cause of immunodeficiency disorders. In fact, immunodeficiency disorders are characterized by a deficiency or impairment of white blood cells, which are essential components of the immune system.

It provides information about the client's white blood cell count, including different types of white blood cells, such as lymphocytes, which play a crucial role in the immune response.
Incorrect choices:
b. Blood glucose level is not specifically related to monitoring the immune status or treatment response in clients with immunodeficiency disorders.
c. Liver function tests (LFTs) are important for monitoring liver health but are not directly related to the immune status or treatment response in clients with immunodeficiency disorders.
d. An electrolyte panel is used to assess the balance of electrolytes in the body and is not specifically related to monitoring the immune status or treatment response in clients with immunodeficiency disorders.

It leads to impaired T cell function and is associated with developmental delays, chronic infections, and autoimmune problems.
Incorrect choices:
a. X-linked agammaglobulinemia is a primary immunodeficiency disorder that primarily affects B cell function, leading to a deficiency of immunoglobulins (antibodies).
c. Wiskott-Aldrich syndrome is an X-linked recessive disorder characterized by a triad of symptoms: eczema, thrombocytopenia (low platelet count), and immunodeficiency.
d. Severe combined immunodeficiency (SCID) is a group of rare disorders characterized by a severe deficiency of T cells, B cells, and natural killer (NK) cells.
