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

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.

Explanation: The correct answer is c. Frequent and severe infections are common clinical manifestations of immunodeficiency disorders. The weakened immune system is unable to effectively defend against infections, leading to recurrent and severe infections.

Incorrect choices:

a. Severe allergic reactions are more characteristic of allergies or hypersensitivity disorders, not immunodeficiency disorders.

b. Chronic inflammation can be seen in various conditions, but it is not a specific clinical manifestation of immunodeficiency disorders.

d. Autoimmune diseases result from an overactive immune response attacking the body's own tissues, which is the opposite of immunodeficiency disorders where the immune system is weakened and unable to adequately protect against infections.
