Which of the following diagnostic tests is commonly used to assess immune function in individuals suspected of having an immunodeficiency disorder?

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 a. "Practice proper hand hygiene and infection prevention measures." Proper hand hygiene, including regular handwashing with soap and water, is essential for clients with immunodeficiency disorders to reduce the risk of acquiring infections. It is one of the most effective ways to prevent the transmission of pathogens.

Incorrect choices:

b. Engaging in intense physical activities is not recommended for clients with immunodeficiency disorders, as it can put additional stress on the immune system. Moderate, regular exercise is beneficial for overall health, but extreme physical activities may be harmful to the immune system.

c. There is no need for clients with immunodeficiency disorders to limit their fluid intake unless they have a medical condition that requires fluid restriction. Adequate fluid intake is essential for overall health and immune function.

d. Consuming a diet rich in raw and undercooked meat is not recommended for clients with immunodeficiency disorders, as it can increase the risk of foodborne infections. It is important for these clients to follow food safety guidelines and avoid consuming raw or undercooked meat.
