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 a. Wear a mask when entering the client's room. Wearing a mask when entering the client's room is a standard precaution that can help prevent the transmission of infectious agents, especially for clients with immunodeficiency disorders who are at a higher risk of infections.

Incorrect choices:

b. Using a sterile dressing change technique for all wound care may not be necessary for all clients with immunodeficiency disorders. It is essential to assess the client's specific condition and wound characteristics to determine the appropriate dressing change technique.

c. Encouraging the client to wear a mask at all times may not be feasible or necessary, as masks are typically used to prevent the transmission of infections from the client to others, not the other way around.

d. Placing the client on strict isolation precautions may not be necessary for all clients with immunodeficiency disorders. The appropriate level of isolation precautions should be determined based on the client's specific condition and risk factors for infections.
