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 a. Severe combined immunodeficiency (SCID). SCID is a severe and rare primary immunodeficiency disorder characterized by the absence or severe impairment of both T and B cells, leading to a profound deficiency in cellular and humoral immunity.

Incorrect choices:

b. X-linked agammaglobulinemia (XLA) primarily affects B-cell function, resulting in a lack of mature B cells and low levels of immunoglobulins, but does not typically involve T-cell deficiency.

c. Wiskott-Aldrich syndrome affects platelet function and immune system regulation, but it is not characterized by a deficiency of both T and B cells.

d. Common variable immunodeficiency (CVID) is characterized by reduced levels of immunoglobulins, particularly IgG and IgA, but it does not typically lead to a complete deficiency of both T and B cells.

Explanation: The correct answer is a. The procedure will assess the function of the client's immune system. A bone marrow aspiration is a diagnostic procedure that involves extracting a sample of bone marrow to evaluate the production and function of blood cells, including immune cells.

Incorrect choices:

b. A bone marrow aspiration does not involve removing lymph nodes. It is a procedure specifically focused on obtaining a bone marrow sample.

c. General anesthesia is not typically used for a bone marrow aspiration. Instead, local anesthesia is administered to numb the area around the bone marrow site.

d. A bone marrow aspiration is not a blood test to measure circulating antibodies. It is used to evaluate the bone marrow's cellular components, not circulating antibodies.
