LD
Arturiano [62]

Answer:

The best explanation for the increased lymphocyte levels in Kaya is that she was not tissue typed prior to her surgery, and her body is mounting an immune response.

Explanation:

When performing an organ transplant, it must be verified whether the organ to be transplanted is compatible -by tissue typing- with the recipient, since it is recognized as a foreign body by the body and can be rejected.

One of the immunological responses to organ rejection is called cell rejection, involving T-helper and cytotoxic lymphocytes.

<u>It is very likely that in Kaya's case the tests have not been performed correctly, and she is experiencing rejection of the organ she received</u>. The progressive increase in lymphocytes may be an indication of this.

The other options are not possible because:

  • <em>Administering </em><u><em>antibiotics</em></u><em> should not raise lymphocyte levels. </em>
  • <em>There is no evidence of </em><u><em>antigen </em></u><em>attack. </em>
  • <u><em>Immunosuppressant drugs</em></u><em> do not increase lymphocyte count.</em>
