a. Selective IgM deficiency
X-linked agammaglobulinemia
Common variable immunodeficiency (CVID)
Selective IgA deficiency
The Correct Answer is D
Explanation: The correct answer is d. Selective IgA deficiency. This disorder is characterized by a lack of immunoglobulin A, which can lead to an increased susceptibility to infections, particularly in the respiratory and gastrointestinal tracts.
Incorrect choices:
a. Selective IgM deficiency is a rare immunodeficiency disorder characterized by a lack of immunoglobulin M (IgM), not IgA.
b. X-linked agammaglobulinemia is a primary immunodeficiency disorder caused by a mutation in the BTK gene, resulting in a deficiency of B cells and immunoglobulins.

Correct Answer is A
Explanation
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.
Correct Answer is C
Explanation
Explanation: The correct answer is c. Frequent and severe infections. One of the hallmark features of immunodeficiency disorders is an increased susceptibility to infections. Individuals with immunodeficiencies may experience frequent and severe infections, including bacterial, viral, and fungal infections.
Incorrect choices:
a. Excessive inflammation at the site of infection is not a common clinical manifestation of immunodeficiency disorders. Immunodeficiencies are characterized by a weakened immune response, which may result in a reduced inflammatory response to infections.
b. Hyperactive immune response to allergens is seen in allergies and autoimmune disorders, not immunodeficiency disorders.
d. Immunodeficiency disorders are characterized by a lack or dysfunction of specific immune components, such as B cells or T cells, leading to a decreased production of antibodies, not increased.
