The nurse is caring for a client suspected of having an immunodeficiency disorder. Which diagnostic test should the nurse anticipate being ordered to confirm the diagnosis?

Explanation: The correct answer is c. Common variable immunodeficiency (CVID) is characterized by a deficiency or absence of B cells, leading to a reduced ability to produce antibodies and an increased susceptibility to infections.

Incorrect choices:

a. DiGeorge syndrome is a disorder caused by a genetic defect resulting in the underdevelopment of the thymus and parathyroid glands, leading to T cell deficiency.

b. Severe combined immunodeficiency (SCID) is a severe form of immunodeficiency that affects both B and T cells, leading to a complete absence or dysfunction of the immune system.

d. Wiskott-Aldrich syndrome is a rare X-linked genetic disorder characterized by a triad of symptoms, including eczema, low platelet count, and immunodeficiency. It primarily affects T cells and platelets, not B cells.

Explanation: The correct answer is d. Ensuring the client receives prophylactic antibiotics as prescribed. Prophylactic antibiotics are commonly prescribed for clients with immunodeficiency disorders to prevent bacterial infections. It is essential to adhere to the prescribed antibiotic regimen to minimize the risk of infections in these clients.

Incorrect choices:

a. Administering live vaccines is contraindicated in clients with immunodeficiency disorders, as live vaccines can cause severe infections in this population. Only inactivated vaccines are recommended for these clients.

b. Regular physical exercise is beneficial for overall health, but it is not a specific intervention for managing immunodeficiency disorders.

c. Strict isolation precautions may be necessary for clients with severe immunodeficiency or during periods of increased infection risk, but it is not the priority intervention for all clients with immunodeficiency disorders.
