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.

Correct Answer is D
Explanation
Explanation: The correct answer is d. Immunodeficiency disorders can be caused by medications or medical treatments. Immunodeficiency disorders are conditions in which the immune system is weakened or dysfunctional, leading to an increased susceptibility to infections. They can be primary (genetic) or secondary (acquired). Secondary immunodeficiency disorders can be caused by various factors, including medications (e.g., immunosuppressive drugs used after organ transplants), medical treatments (e.g., chemotherapy for cancer), and certain diseases (e.g., HIV/AIDS).
Incorrect choices:
a. Immunodeficiency disorders are characterized by a weakened immune system, not an overactive one. Overactive immune responses are seen in autoimmune disorders.
b. Immunodeficiency disorders can be both primary (genetic) and secondary (acquired) in nature. While some immunodeficiencies are genetic, others can be acquired later in life due to various factors.
c. Immunodeficiency disorders result in a decreased ability to fight infections, not an increased one. Individuals with immunodeficiencies are more susceptible to infections and may experience recurrent or severe infections.
Correct Answer is C
Explanation
Explanation: The correct answer is c. Implement strict infection control measures. Clients with immunodeficiency disorders have a weakened immune system and are more susceptible to infections. Implementing strict infection control measures, such as hand hygiene, using personal protective equipment, and limiting exposure to potential sources of infection, can help prevent the spread of pathogens and protect the client from infections.
Incorrect choices:
a. Encouraging the client to participate in crowded social gatherings can put the client at risk of exposure to infectious agents, which is not appropriate for someone with immunodeficiency.
b. Live vaccines contain weakened pathogens and are contraindicated for clients with immunodeficiency disorders, as they can cause serious infections in this population.
d. While a diet high in fresh fruits and vegetables is generally beneficial for overall health, it does not specifically address the increased risk of infections in clients with immunodeficiency disorders. Strict infection control measures are more relevant to preventing infections in these clients.
