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

B.

Chest X-ray

C.

Serum immunoglobulin levels

D.

Complete blood count (CBC)

Answer and Explanation

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 D

Explanation

Explanation: The correct answer is d. Maintain strict hand hygiene and utilize protective equipment when providing care. Children with severe combined immunodeficiency (SCID) have a severely compromised immune system, making them highly susceptible to infections. Strict hand hygiene and the use of protective equipment, such as gloves and masks, are essential in preventing the transmission of infections to the child.

Incorrect choices:

a. Placing the child on contact precautions may not be sufficient to protect them from infections due to their high susceptibility. Additional precautions, such as strict hand hygiene and protective equipment, should be implemented.

b. Encouraging the child to play with other children may increase the risk of exposure to infections. Children with SCID should be protected from contact with potential sources of infection.

c. Live attenuated vaccines are contraindicated for children with SCID, as they can cause severe infections. Only inactivated vaccines are recommended to avoid the risk of vaccine-associated infections.

Correct Answer is B

Explanation

Explanation: The correct answer is b. DiGeorge syndrome. This disorder is caused by a deletion in chromosome 22, resulting in the underdevelopment of the thymus and parathyroid glands. It leads to impaired T cell function and is associated with developmental delays, chronic infections, and autoimmune problems.

Incorrect choices:

a. X-linked agammaglobulinemia is a primary immunodeficiency disorder that primarily affects B cell function, leading to a deficiency of immunoglobulins (antibodies).

c. Wiskott-Aldrich syndrome is an X-linked recessive disorder characterized by a triad of symptoms: eczema, thrombocytopenia (low platelet count), and immunodeficiency.

d. Severe combined immunodeficiency (SCID) is a group of rare disorders characterized by a severe deficiency of T cells, B cells, and natural killer (NK) cells.
