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?
Complete blood count (CBC)
Urinalysis
Skin testing for allergies
Flow cytometry for lymphocyte subsets
The Correct Answer is D
Explanation: The correct answer is d. Flow cytometry for lymphocyte subsets. Flow cytometry is a diagnostic test used to analyze the quantity and types of lymphocytes in the blood, which helps identify abnormalities in the immune system and diagnose immunodeficiency disorders.
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. Chronic diarrhea. Primary immunodeficiency disorders can affect the gastrointestinal system, leading to chronic diarrhea due to frequent infections and inflammation.
Incorrect choices:
a. Unexplained weight loss is not a specific symptom of primary immunodeficiency disorders. It may be seen in various other medical conditions, such as cancer or metabolic disorders.
b. Recurrent skin rashes are not a characteristic symptom of primary immunodeficiency disorders. Skin rashes may be caused by allergic reactions or dermatological conditions.
d. Difficulty falling asleep is not typically associated with primary immunodeficiency disorders. It may be related to sleep disorders or anxiety.
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.
