Which of the following immunodeficiency disorders is characterized by a deficiency of immunoglobulin A (Ig

a. Severe combined immunodeficiency (SCID)

Common variable immunodeficiency (CVID)

DiGeorge syndrome

Wiskott-Aldrich syndrome

Answer and Explanation

The Correct Answer is B

Explanation: The correct answer is b. Common variable immunodeficiency (CVID). CVID is a primary immunodeficiency disorder characterized by a reduced level of immunoglobulins, particularly IgA, leading to an increased susceptibility to infections.

Incorrect choices:

a. Severe combined immunodeficiency (SCID) is a more severe immunodeficiency disorder that affects multiple components of the immune system, not specifically IgA levels.

c. DiGeorge syndrome is caused by a genetic abnormality and is characterized by a defect in the development of certain organs, including the thymus and parathyroid glands. It may result in immune system abnormalities but does not primarily involve IgA deficiency.

d. Wiskott-Aldrich syndrome is a rare X-linked genetic disorder that affects platelet function and immune system regulation but is not specifically associated with IgA deficiency.

Correct Answer is D

Explanation

Explanation: The correct answer is d. Selective IgA deficiency. This disorder is characterized by a lack of immunoglobulin A, which can lead to an increased susceptibility to infections, particularly in the respiratory and gastrointestinal tracts.

Incorrect choices:

a. Selective IgM deficiency is a rare immunodeficiency disorder characterized by a lack of immunoglobulin M (IgM), not IgA.

b. X-linked agammaglobulinemia is a primary immunodeficiency disorder caused by a mutation in the BTK gene, resulting in a deficiency of B cells and immunoglobulins.

c. Common variable immunodeficiency (CVID) is a heterogeneous group of disorders characterized by decreased levels of immunoglobulins, including IgA, IgG, and IgM.

A. "I should eat a balanced diet with plenty of fruits and vegetables." B. "I will avoid consuming raw or undercooked meat and eggs." C. "I need to limit my fluid intake to prevent fluid overload." D. "I will avoid unpasteurized dairy products to reduce the risk of infections."

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.
