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)
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 D
Explanation
Explanation: The correct answer is d. Teach the client about the importance of hand hygiene and infection control measures. For clients with immunodeficiency disorders, preventing infections is of utmost importance. Hand hygiene and infection control measures, such as proper handwashing techniques and avoiding contact with sick individuals, can help reduce the risk of acquiring infections.
Incorrect choices:
a. While consuming a diet rich in probiotics may be beneficial for gut health, there is no specific evidence to suggest that it will prevent infections in clients with immunodeficiency disorders.
b. Engaging in regular exercise may have various health benefits, but it may not necessarily boost the immune system in clients with immunodeficiency disorders. In fact, excessive exercise can even increase the risk of infections in these individuals.
c. Live vaccines are contraindicated for clients with immunodeficiency disorders, as they can cause severe infections. Only inactivated vaccines are recommended to avoid the risk of vaccine-associated infections.
Correct Answer is B
Explanation
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.
