The nurse is providing education to a client with a primary immunodeficiency disorder. Which statement by the client indicates a need for further teaching?

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.

Explanation: The correct answer is c. Immunodeficiency disorders involve a deficiency in the body's ability to fight infections. These disorders are characterized by a weakened or impaired immune system, leading to an increased susceptibility to infections.

Incorrect choices:

a. Immunodeficiency disorders are not characterized by an overactive immune system. Instead, they are characterized by an underactive or weakened immune system.

b. Immunodeficiency disorders do not result from excessive production of antibodies. Instead, they involve a deficiency in the production or function of immune cells or antibodies.

d. Immunodeficiency disorders primarily affect the immune system, not the nervous system.
