What is the primary cause of immunodeficiency disorders?

Environmental factors

Genetic or inherited defects

Autoimmune reactions

Excessive production of white blood cells

Answer and Explanation

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.

Correct Answer is B

Explanation

Explanation: The correct answer is b. X-linked agammaglobulinemia. X-linked agammaglobulinemia is a primary immunodeficiency disorder caused by a genetic mutation that leads to the absence of mature B cells, resulting in an inability to produce antibodies (immunoglobulins). As a result, individuals with this disorder are highly susceptible to infections, especially bacterial infections.

Incorrect choices:

a. DiGeorge syndrome is a primary immunodeficiency disorder characterized by abnormalities in the development of certain organs, including the thymus, leading to impaired T cell function.

c. Severe combined immunodeficiency (SCID) is a group of rare genetic disorders that affect both T cells and B cells, resulting in a severe impairment of the immune system.

d. Acquired immunodeficiency syndrome (AIDS) is a secondary immunodeficiency disorder caused by the human immunodeficiency virus (HIV) infection, which specifically targets and destroys CD4+ T cells, weakening the immune system's ability to fight infections.

A. Administering live vaccines as scheduled. B. Encouraging the client to perform strenuous physical activities. C. Limiting the client's intake of fluids. D. Educating the client on proper hand hygiene.

Correct Answer is D

Explanation

Explanation: The correct answer is d. Educating the client on proper hand hygiene. Educating the client on proper hand hygiene is essential to reduce the risk of infections in individuals with immunodeficiency disorders. Frequent handwashing is a simple yet effective way to prevent the transmission of infectious agents.

Incorrect choices:

a. Administering live vaccines is contraindicated for clients with immunodeficiency disorders, as live vaccines contain weakened pathogens that can cause serious infections in this population.

b. Encouraging the client to perform strenuous physical activities is not appropriate for someone with immunodeficiency, as strenuous activities can put additional strain on the immune system and increase the risk of infections.

c. Limiting the client's intake of fluids is not a necessary intervention for immunodeficiency disorders. Adequate fluid intake is generally important for overall health, but it is not directly related to managing immunodeficiency disorders.
