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 d. Absence or significantly reduced T cell levels. Severe combined immunodeficiency (SCID) is characterized by a severe deficiency or absence of T cells, which are essential for cell-mediated immunity.

Incorrect choices:

a. Increased levels of circulating B cells are not characteristic of SCID. In SCID, both T and B cell immunity are affected, and the client may have reduced levels of both.

b. Elevated immunoglobulin M (IgM) levels may occur in certain types of immunodeficiency disorders, but it is not a specific finding for SCID.

c. Abnormal antibody response to vaccinations can be observed in various immunodeficiency disorders, but it does not specifically indicate SCID.

Explanation: The correct answer is c. Immunodeficiency disorders can lead to an increased susceptibility to infections. Immunodeficiency disorders are characterized by a weakened or impaired immune system, making individuals more susceptible to infections, both common and opportunistic.

Incorrect choices:

a. Immunodeficiency disorders result from a weakened immune system, not an overactive one. In overactive immune responses, autoimmune disorders may occur.

b. While some immunodeficiency disorders have a genetic basis, not all cases are caused by genetic factors. Some immunodeficiency disorders can be acquired later in life due to infections, medications, or other factors.

d. Immunodeficiency disorders are not typically treated with anti-inflammatory medications. Treatment may involve immunoglobulin replacement therapy, antiviral medications, or stem cell transplantation, depending on the specific disorder and its underlying cause.
