The nurse is assisting with a bone marrow aspiration for a client with suspected immunodeficiency disorder. Which information should the nurse provide to the client regarding this procedure?

Explanation: The correct answer is c. Common variable immunodeficiency (CVID) is characterized by a deficiency or absence of B cells, leading to a reduced ability to produce antibodies and an increased susceptibility to infections.

Incorrect choices:

a. DiGeorge syndrome is a disorder caused by a genetic defect resulting in the underdevelopment of the thymus and parathyroid glands, leading to T cell deficiency.

b. Severe combined immunodeficiency (SCID) is a severe form of immunodeficiency that affects both B and T cells, leading to a complete absence or dysfunction of the immune system.

d. Wiskott-Aldrich syndrome is a rare X-linked genetic disorder characterized by a triad of symptoms, including eczema, low platelet count, and immunodeficiency. It primarily affects T cells and platelets, not 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.
