The nurse is caring for an infant suspected of having severe combined immunodeficiency (SCID). Which diagnostic test should the nurse anticipate being prescribed for the infant?

Explanation: The correct answer is a. Wear a mask when entering the client's room. Wearing a mask when entering the client's room is a standard precaution that can help prevent the transmission of infectious agents, especially for clients with immunodeficiency disorders who are at a higher risk of infections.

Incorrect choices:

b. Using a sterile dressing change technique for all wound care may not be necessary for all clients with immunodeficiency disorders. It is essential to assess the client's specific condition and wound characteristics to determine the appropriate dressing change technique.

c. Encouraging the client to wear a mask at all times may not be feasible or necessary, as masks are typically used to prevent the transmission of infections from the client to others, not the other way around.

d. Placing the client on strict isolation precautions may not be necessary for all clients with immunodeficiency disorders. The appropriate level of isolation precautions should be determined based on the client's specific condition and risk factors for infections.

Explanation: The correct answer is c. Severe combined immunodeficiency (SCID). SCID is a group of rare genetic disorders that affect both T cells and B cells, resulting in a severe impairment of the immune system. Individuals with SCID are highly susceptible to infections and may need to live in a protected environment to avoid exposure to pathogens, hence the term "bubble boy disease."

Incorrect choices:

a. DiGeorge syndrome is a primary immunodeficiency disorder characterized by abnormalities in the development of certain organs, including the thymus, leading to impaired T cell function, but it does not affect B cell function.

b. X-linked agammaglobulinemia is a primary immunodeficiency disorder characterized by a lack of mature B cells and an inability to produce antibodies, but it does not affect T cell function.

d. Acquired immunodeficiency syndrome (AIDS) is a secondary immunodeficiency disorder caused by the human immunodeficiency virus (HIV) infection, which specifically targets and destroys CD4+ T cells, but it does not affect B cell function.
