The nurse is caring for a client with human immunodeficiency virus (HIV) infection. Which intervention should the nurse include in the client's plan of care?

Explanation: The correct answer is b. Recurrent skin infections. Recurrent skin infections are common clinical manifestations of immunodeficiency disorders in the elderly. The weakened immune system makes the skin more susceptible to infections and delays wound healing.

Incorrect choices:

a. Impaired balance and coordination are more commonly associated with neurological disorders or conditions affecting the musculoskeletal system, not immunodeficiency disorders.

c. Vision changes and blindness may be seen in conditions affecting the eyes or the visual system but are not typical clinical manifestations of immunodeficiency disorders.

d. Hearing loss is more commonly associated with conditions affecting the ears or the auditory system and is not a typical clinical manifestation of immunodeficiency disorders.

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.

c. Common variable immunodeficiency (CVID) is a heterogeneous group of disorders characterized by decreased levels of immunoglobulins, including IgA, IgG, and IgM.
