The nurse is caring for a client suspected of having a primary immunodeficiency disorder. Which laboratory test should the nurse anticipate being prescribed for the client?a. Enzyme-linked immunosorbent assay (ELIS
Chest X-ray
Serum immunoglobulin levels
Complete blood count (CBC)
The Correct Answer is C
Explanation: The correct answer is c. Serum immunoglobulin levels. A primary immunodeficiency disorder often results in abnormal levels of immunoglobulins (antibodies) in the blood. Measuring serum immunoglobulin levels can help identify potential deficiencies and guide the diagnosis of primary immunodeficiency disorders.
Incorrect choices:
a. Enzyme-linked immunosorbent assay (ELISA) is a test used to detect specific antibodies or antigens in the blood, but it is not specific to diagnosing primary immunodeficiency disorders.
b. A chest X-ray is not a specific test for diagnosing primary immunodeficiency disorders. It is typically used to assess the condition of the lungs and chest organs.
d. A complete blood count (CBC) is a general blood test that may reveal abnormalities in white blood cell count but does not specifically assess immunoglobulin levels.

Correct Answer is C
Explanation
The correct answer is c. Ataxia-telangiectasia. Ataxia-telangiectasia is a rare genetic disorder that affects the cerebellum, causing poor muscle coordination (ataxia) and small, dilated blood vessels (telangiectasias). It also leads to defective T-cell function, making affected individuals more susceptible to infections.
Incorrect choices:
a. X-linked agammaglobulinemia (XLA) is a primary immunodeficiency disorder that primarily affects B-cell function, leading to a lack of mature B cells and low levels of immunoglobulins, but does not involve defective T-cell function.
b. Selective immunoglobulin A (IgA) deficiency is characterized by a deficiency of IgA, but it does not typically lead to defective T-cell function.
d. DiGeorge syndrome is caused by a deletion on chromosome 22 and primarily affects the development of certain organs, including the thymus and parathyroid glands, resulting in T-cell deficiency. While it may lead to some B-cell abnormalities, defective T-cell function is the hallmark of this disorder.
Correct Answer is C
Explanation
Explanation: The correct answer is c. Immunodeficiency disorders can lead to an increased susceptibility to infections. Immunodeficiency disorders are characterized by a weakened or impaired immune system, making individuals more susceptible to infections, both common and opportunistic.
Incorrect choices:
a. Immunodeficiency disorders result from a weakened immune system, not an overactive one. In overactive immune responses, autoimmune disorders may occur.
b. While some immunodeficiency disorders have a genetic basis, not all cases are caused by genetic factors. Some immunodeficiency disorders can be acquired later in life due to infections, medications, or other factors.
d. Immunodeficiency disorders are not typically treated with anti-inflammatory medications. Treatment may involve immunoglobulin replacement therapy, antiviral medications, or stem cell transplantation, depending on the specific disorder and its underlying cause.
