The nurse is reviewing the diagnostic evaluation for a client with suspected immunodeficiency disorder. Which finding would be consistent with a potential diagnosis of severe combined immunodeficiency (SCID)?
Increased levels of circulating B cells
Elevated immunoglobulin M (IgM) levels
Abnormal antibody response to vaccinations
Absence or significantly reduced T cell levels
The Correct Answer is D
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.

Correct Answer is A
Explanation
Explanation: The correct answer is a. "Practice proper hand hygiene and infection prevention measures." Proper hand hygiene, including regular handwashing with soap and water, is essential for clients with immunodeficiency disorders to reduce the risk of acquiring infections. It is one of the most effective ways to prevent the transmission of pathogens.
Incorrect choices:
b. Engaging in intense physical activities is not recommended for clients with immunodeficiency disorders, as it can put additional stress on the immune system. Moderate, regular exercise is beneficial for overall health, but extreme physical activities may be harmful to the immune system.
c. There is no need for clients with immunodeficiency disorders to limit their fluid intake unless they have a medical condition that requires fluid restriction. Adequate fluid intake is essential for overall health and immune function.
d. Consuming a diet rich in raw and undercooked meat is not recommended for clients with immunodeficiency disorders, as it can increase the risk of foodborne infections. It is important for these clients to follow food safety guidelines and avoid consuming raw or undercooked meat.
Correct Answer is B
Explanation
Explanation: The correct answer is b. Genetic or inherited defects. Immunodeficiency disorders are primarily caused by genetic mutations or defects that result in a weakened or impaired immune system.
Incorrect choices:
a. While environmental factors can contribute to the development of secondary immunodeficiency disorders, they are not the primary cause of most immunodeficiency disorders.
c. Autoimmune reactions are not the primary cause of immunodeficiency disorders. Autoimmune disorders involve the immune system attacking the body's own tissues, not a deficiency in the immune system.
d. Excessive production of white blood cells is not the primary cause of immunodeficiency disorders. In fact, immunodeficiency disorders are characterized by a deficiency or impairment of white blood cells, which are essential components of the immune system.
