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>
