Answer to Question 1

C
Feedback:
Etanercept is given by injecting it into the subcutaneous tissues. The injection sites should be rotated to avoid tissue damage. Because it is not taken orally, there is no requirement related to amount of water to be taken or waiting an hour after taking an antacid. Etanercept is not injected into the muscle but rather into the subcutaneous tissue.

Answer to Question 2

B
Feedback:
The histocompatibility antigens are proteins that are seen on the top of the cell membrane. T cells use these antigens as the identifying proteins that identify a cell as a self-cell. If these antigens are not present on a cell membrane, the T cells will destroy that cell, determining that it is foreign. The histocompatibility antigens are not involved in reproduction. They do not produce antibodies nor do they stimulate white blood cell production.
