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.

Correct Answer is D
Explanation
Explanation: The correct answer is d. Educating the client on proper hand hygiene. Educating the client on proper hand hygiene is essential to reduce the risk of infections in individuals with immunodeficiency disorders. Frequent handwashing is a simple yet effective way to prevent the transmission of infectious agents.
Incorrect choices:
a. Administering live vaccines is contraindicated for clients with immunodeficiency disorders, as live vaccines contain weakened pathogens that can cause serious infections in this population.
b. Encouraging the client to perform strenuous physical activities is not appropriate for someone with immunodeficiency, as strenuous activities can put additional strain on the immune system and increase the risk of infections.
c. Limiting the client's intake of fluids is not a necessary intervention for immunodeficiency disorders. Adequate fluid intake is generally important for overall health, but it is not directly related to managing immunodeficiency disorders.
Correct Answer is C
Explanation
Explanation: The correct answer is c. Allergic reactions and skin rashes are not typically associated with immunodeficiency disorders. Immunodeficiency disorders primarily result in an increased susceptibility to infections and recurrent, severe infections.
Incorrect choices:
a. Frequent, severe infections are a common symptom of immunodeficiency disorders due to the weakened immune response, making individuals more susceptible to infections.
b. Fatigue and weakness can occur in individuals with immunodeficiency disorders due to the impact of chronic infections on the body's energy reserves.
d. Delayed wound healing may occur in individuals with immunodeficiency disorders due to the impaired immune response and decreased ability to fight infections at the site of a wound.
