Which type of immunodeficiency disorder is characterized by a lack of mature B cells and an inability to produce antibodies?

DiGeorge syndrome

X-linked agammaglobulinemia

Severe combined immunodeficiency (SCID)

Acquired immunodeficiency syndrome (AIDS)

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is B

Explanation

Explanation: The correct answer is b. "I will make sure to get all the live vaccines recommended for my age." Clients with immunodeficiency disorders should not receive live vaccines, as they can cause severe infections in this population. Only inactivated vaccines are recommended to avoid the risk of vaccine-associated infections.

Incorrect choices:

a. Avoiding contact with individuals who have colds or other infections is essential for clients with immunodeficiency disorders, as they are at a higher risk of acquiring infections.

c. Practicing good hand hygiene and washing hands frequently are essential infection prevention measures for clients with immunodeficiency disorders.

d. Informing the healthcare provider if any signs of infection develop is crucial for early detection and treatment of infections in clients with immunodeficiency disorders.

A. Increased levels of circulating B cells B. Elevated immunoglobulin M (IgM) levels C. Abnormal antibody response to vaccinations D. Absence or significantly reduced T cell levels

Correct Answer is D

Explanation

Explanation: The correct answer is d. Absence or significantly reduced T cell levels. Severe combined immunodeficiency (SCID) is characterized by a severe deficiency or absence of T cells, which are essential for cell-mediated immunity.

Incorrect choices:

a. Increased levels of circulating B cells are not characteristic of SCID. In SCID, both T and B cell immunity are affected, and the client may have reduced levels of both.

b. Elevated immunoglobulin M (IgM) levels may occur in certain types of immunodeficiency disorders, but it is not a specific finding for SCID.

c. Abnormal antibody response to vaccinations can be observed in various immunodeficiency disorders, but it does not specifically indicate SCID.
