Which type of immunodeficiency disorder is inherited in an X-linked recessive pattern and primarily affects males, leading to the absence of mature B cells and immunoglobulins?
Selective IgA deficiency
DiGeorge syndrome
X-linked agammaglobulinemia
Severe combined immunodeficiency (SCID)
The Correct Answer is C
Explanation: The correct answer is c. X-linked agammaglobulinemia. This disorder primarily affects males and is caused by mutations in the BTK gene, resulting in a lack of mature B cells and immunoglobulins.
Incorrect choices:
a. Selective IgA deficiency is a primary immunodeficiency disorder characterized by a deficiency of immunoglobulin A (IgA), and it can affect both males and females.
b. DiGeorge syndrome is caused by a chromosome 22 deletion and is not inherited in an X-linked recessive pattern.
d. Severe combined immunodeficiency (SCID) is a group of disorders that can be inherited in various patterns, including autosomal recessive, autosomal dominant, or X-linked recessive. SCID affects both males and females and results in a severe deficiency of T cells, B cells, and natural killer (NK) cells.

Correct Answer is C
Explanation
Explanation: The correct answer is c. "I need to limit my fluid intake to prevent fluid overload." There is no specific recommendation to limit fluid intake for clients with immunodeficiency disorders unless they have a medical condition that requires fluid restriction. Adequate fluid intake is essential for overall health, including immune function.
Incorrect choices:
a. Eating a balanced diet with plenty of fruits and vegetables is important for overall well-being, including supporting the immune system in clients with immunodeficiency disorders.
b. Avoiding raw or undercooked meat and eggs is recommended to prevent foodborne infections in all individuals, including those with immunodeficiency disorders.
d. Avoiding unpasteurized dairy products is important to reduce the risk of infections caused by foodborne pathogens in all individuals, including those with immunodeficiency disorders.
Correct Answer is C
Explanation
Explanation: The correct answer is c. Frequent and severe infections. One of the hallmark features of immunodeficiency disorders is an increased susceptibility to infections. Individuals with immunodeficiencies may experience frequent and severe infections, including bacterial, viral, and fungal infections.
Incorrect choices:
a. Excessive inflammation at the site of infection is not a common clinical manifestation of immunodeficiency disorders. Immunodeficiencies are characterized by a weakened immune response, which may result in a reduced inflammatory response to infections.
b. Hyperactive immune response to allergens is seen in allergies and autoimmune disorders, not immunodeficiency disorders.
d. Immunodeficiency disorders are characterized by a lack or dysfunction of specific immune components, such as B cells or T cells, leading to a decreased production of antibodies, not increased.
