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 D
Explanation
Explanation: The correct answer is d. Immunoglobulin levels. Immunoglobulin levels, specifically IgG, IgM, and IgA, are commonly measured to assess immune function and identify deficiencies in immunoglobulin production. Abnormalities in immunoglobulin levels can indicate the presence of an immunodeficiency disorder.
Incorrect choices:
a. A complete blood count (CBC) provides information about various blood components, such as red blood cells, white blood cells, and platelets, but it does not specifically assess immune function.
b. A chest X-ray may be used to evaluate the condition of the lungs and detect infections, but it is not a specific test for immunodeficiency disorders.
c. Allergy skin testing is used to diagnose allergies and assess the body's response to allergens, but it is not a diagnostic test for immunodeficiency disorders.
Correct Answer is C
Explanation
Explanation: The correct answer is c. "I should avoid close contact with pets to reduce the risk of infections." While it is essential to practice good hygiene when handling pets, avoiding close contact with pets is not typically necessary for clients with immunodeficiency disorders unless they have a specific allergy or pet-related infection.
Incorrect choices:
a. Avoiding crowded places and large gatherings is important for clients with immunodeficiency disorders, as it helps reduce the risk of exposure to infections.
b. Cleaning and disinfecting frequently touched surfaces in the home regularly can help prevent the transmission of infections in clients with immunodeficiency disorders.
d. Wearing a mask when visiting the hospital or healthcare settings is a standard infection prevention measure for clients with immunodeficiency disorders to reduce the risk of acquiring infections from others.
