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. Primary immunodeficiency disorders are typically present at birth or during early childhood and are caused by genetic defects that affect the function of the immune system. They are not acquired later in life due to environmental factors.

Incorrect choices:

a. Primary immunodeficiency disorders are not acquired later in life; they are usually genetic and present from birth.

d. Primary immunodeficiency disorders are often not easily treatable with antibiotics and antiviral medications because they result from genetic defects in the immune system.

Explanation: The correct answer is c. Flow cytometry. Flow cytometry is a specialized test used to analyze the different cell types in a blood sample. In the case of SCID, flow cytometry can help identify the absence or severe deficiency of T cells and B cells, which are essential components of the immune system.
