Which of the following is not a common symptom of immunodeficiency disorders?

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.

Explanation: The correct answer is d. Maintain strict hand hygiene and utilize protective equipment when providing care. Children with severe combined immunodeficiency (SCID) have a severely compromised immune system, making them highly susceptible to infections. Strict hand hygiene and the use of protective equipment, such as gloves and masks, are essential in preventing the transmission of infections to the child.

Incorrect choices:

a. Placing the child on contact precautions may not be sufficient to protect them from infections due to their high susceptibility. Additional precautions, such as strict hand hygiene and protective equipment, should be implemented.

b. Encouraging the child to play with other children may increase the risk of exposure to infections. Children with SCID should be protected from contact with potential sources of infection.

c. Live attenuated vaccines are contraindicated for children with SCID, as they can cause severe infections. Only inactivated vaccines are recommended to avoid the risk of vaccine-associated infections.
