Which of the following clinical manifestations is often observed in individuals with severe combined immunodeficiency (SCID)?

Explanation: The correct answer is d. Flow cytometry for lymphocyte subsets. Flow cytometry is a diagnostic test used to analyze the quantity and types of lymphocytes in the blood, which helps identify abnormalities in the immune system and diagnose immunodeficiency disorders.

Incorrect choices:

a. A complete blood count (CBC) provides general information about the client's overall blood cell counts, but it does not specifically diagnose immunodeficiency disorders.

b. Urinalysis is used to assess kidney function and identify urinary tract infections but is not a specific test for diagnosing immunodeficiency disorders.

c. Skin testing for allergies is performed to identify allergic reactions to specific allergens and is not used to diagnose immunodeficiency disorders.

Explanation: The correct answer is c. Allergic reactions and skin rashes are not typically associated with immunodeficiency disorders. Immunodeficiency disorders primarily result in an increased susceptibility to infections and recurrent, severe infections.

Incorrect choices:

a. Frequent, severe infections are a common symptom of immunodeficiency disorders due to the weakened immune response, making individuals more susceptible to infections.

b. Fatigue and weakness can occur in individuals with immunodeficiency disorders due to the impact of chronic infections on the body's energy reserves.

d. Delayed wound healing may occur in individuals with immunodeficiency disorders due to the impaired immune response and decreased ability to fight infections at the site of a wound.
