X-linked agammaglobulinemia

DiGeorge syndrome

Wiskott-Aldrich syndrome

Severe combined immunodeficiency (SCID)

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.

Correct Answer is D

Explanation

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.

A. Encourage the client to engage in vigorous physical activities to strengthen the immune system. B. Limit the client's exposure to visitors and restrict contact with other clients in the healthcare setting. C. Administer live vaccines to boost the client's immune response. D. Encourage the client to eat a diet high in fresh fruits and vegetables to improve immune function.

Correct Answer is B

Explanation

Explanation: The correct answer is b. Limit the client's exposure to visitors and restrict contact with other clients in the healthcare setting. Clients with immunodeficiency disorders are at a higher risk of infections due to their weakened immune system. Restricting exposure to potential sources of infection, such as visitors and other sick clients, can help minimize the risk of acquiring infections.

Incorrect choices:

a. Engaging in vigorous physical activities may not be appropriate for clients with immunodeficiency disorders, as it can lead to an increased risk of infections and may not strengthen the immune system in these individuals.

c. Live vaccines are contraindicated for clients with immunodeficiency disorders, as they can cause severe infections in this population. Only inactivated vaccines are recommended to avoid the risk of vaccine-associated infections.

d. While a healthy diet is essential for overall well-being, there is no specific evidence to suggest that a diet high in fresh fruits and vegetables will improve immune function in clients with immunodeficiency disorders. Dietary considerations for these clients may include avoiding certain high-risk foods, but it should be discussed with the healthcare provider based on the specific immunodeficiency disorder.
