The nurse is caring for a client suspected of having an immunodeficiency disorder. Which diagnostic test should the nurse anticipate being ordered to confirm the diagnosis?

Explanation: The correct answer is c. Failure to thrive. SCID is a severe form of immunodeficiency that affects multiple components of the immune system, leading to recurrent and severe infections and failure to thrive in affected infants.

Incorrect choices:

a. Recurrent ear infections are more commonly seen in other types of immunodeficiency disorders, such as selective IgA deficiency.

b. Chronic fatigue and lethargy may be seen in various medical conditions but are not specific to SCID.

d. Persistent joint pain is not a characteristic symptom of SCID. It may be associated with other autoimmune or inflammatory conditions.

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.
