Which of the following diagnostic tests is commonly used to assess immune function in individuals suspected of having an immunodeficiency disorder?

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.

Explanation: The correct answer is c. Immunodeficiency disorders involve a deficiency in the body's ability to fight infections. These disorders are characterized by a weakened or impaired immune system, leading to an increased susceptibility to infections.

Incorrect choices:

a. Immunodeficiency disorders are not characterized by an overactive immune system. Instead, they are characterized by an underactive or weakened immune system.

b. Immunodeficiency disorders do not result from excessive production of antibodies. Instead, they involve a deficiency in the production or function of immune cells or antibodies.

d. Immunodeficiency disorders primarily affect the immune system, not the nervous system.
