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?
Tuberculin skin test (TST)
Western blot test
Flow cytometry
Liver function tests
The Correct Answer is C
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.
Incorrect choices:
a. A tuberculin skin test (TST) is used to detect exposure to tuberculosis (TB) and is not specific to diagnosing SCID.
b. A Western blot test is a type of immunoassay used to detect specific antibodies or antigens in the blood but is not specific to diagnosing SCID.
d. Liver function tests are used to assess the health of the liver and are not specific to diagnosing SCID.

Explanation

Incorrect choices:
a. A complete blood count (CBC) provides general information about the client's overall blood cell counts, but it does not specifically diagnose immunodeficiency disorders.
b. Urinalysis is used to assess kidney function and identify urinary tract infections but is not a specific test for diagnosing immunodeficiency disorders.
c. Skin testing for allergies is performed to identify allergic reactions to specific allergens and is not used to diagnose immunodeficiency disorders.
Correct Answer is C
Explanation
Explanation: The correct answer is c. Administer intramuscular immunoglobulins (IG) as ordered. For clients with immunodeficiency disorders, intramuscular immunoglobulins can be prescribed to provide passive immunity and help prevent infections. Immunoglobulins contain antibodies that the client's immune system may be lacking, offering protection against various pathogens.
Incorrect choices:
a. Encouraging the client to receive live vaccines is not appropriate for clients with immunodeficiency disorders. Live vaccines contain live, attenuated viruses or bacteria, which can cause severe infections in individuals with compromised immune systems.
b. Prescribing broad-spectrum antibiotics prophylactically may be used in some cases, but it is not the first-line treatment for immunodeficiency disorders. It is essential to identify the specific pathogens causing infections before initiating antibiotic therapy to avoid antimicrobial resistance.
d. Initiating high-dose corticosteroid therapy is not appropriate for the management of immunodeficiency disorders. Corticosteroids can suppress the immune system further and increase the risk of infections in these clients.
