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 B

Explanation

Explanation: The correct answer is b. Genetic or inherited defects. Immunodeficiency disorders are primarily caused by genetic mutations or defects that result in a weakened or impaired immune system.

Incorrect choices:

a. While environmental factors can contribute to the development of secondary immunodeficiency disorders, they are not the primary cause of most immunodeficiency disorders.

c. Autoimmune reactions are not the primary cause of immunodeficiency disorders. Autoimmune disorders involve the immune system attacking the body's own tissues, not a deficiency in the immune system.

d. Excessive production of white blood cells is not the primary cause of immunodeficiency disorders. In fact, immunodeficiency disorders are characterized by a deficiency or impairment of white blood cells, which are essential components of the immune system.

A. Encouraging the client to participate in strenuous physical activities. B. Providing a diet high in raw fruits and vegetables to boost the immune system. C. Ensuring the client receives antiretroviral therapy (ART) as prescribed. D. Allowing the client to interact freely with other clients in the healthcare facility.

Correct Answer is C

Explanation

Explanation: The correct answer is c. Ensuring the client receives antiretroviral therapy (ART) as prescribed. ART is the mainstay of treatment for HIV infection and is essential for suppressing viral replication, improving immune function, and preventing disease progression.

Incorrect choices:

a. Encouraging strenuous physical activities is not recommended for clients with HIV infection, as it may place additional stress on the immune system and exacerbate symptoms.

b. While a balanced diet is essential for overall health, there is no specific evidence that a diet high in raw fruits and vegetables alone can boost the immune system sufficiently to manage HIV infection.

d. Clients with HIV infection should follow infection control precautions to prevent the transmission of the virus to others. Interacting freely with other clients may put them and others at risk of infection transmission.
