The nurse is reviewing the diagnostic evaluation for a client with suspected immunodeficiency disorder. Which finding would be consistent with a potential diagnosis of severe combined immunodeficiency (SCID)?

Explanation: The correct answer is c. Primary immunodeficiency disorders are typically present at birth or during early childhood and are caused by genetic defects that affect the function of the immune system. They are not acquired later in life due to environmental factors.

Incorrect choices:

a. Primary immunodeficiency disorders are not acquired later in life; they are usually genetic and present from birth.

b. Primary immunodeficiency disorders are characterized by a weakened or deficient immune response, not an overactive immune response.

d. Primary immunodeficiency disorders are often not easily treatable with antibiotics and antiviral medications because they result from genetic defects in the immune system.

Explanation: The correct answer is d. Abdominal pain and diarrhea. Abdominal pain and diarrhea are common clinical manifestations of immunodeficiency disorders. The weakened immune system makes the child more susceptible to gastrointestinal infections, leading to these symptoms.

Incorrect choices:

a. Rash and hives are more common clinical manifestations of allergic reactions or immune hypersensitivity disorders, not immunodeficiency disorders.

b. Rapid weight loss may be seen in conditions like malnutrition or metabolic disorders but is not a typical clinical manifestation of immunodeficiency disorders.

c. Excessive thirst and frequent urination are clinical manifestations of diabetes or other endocrine disorders, not immunodeficiency disorders.
