Answer to Question 1

C
Feedback:
Systemic absorption of eye drops can be decreased by closing the eye and applying pressure over the tear duct for 3 to 5 minutes after instillation. Pressure should not be applied to the tear duct for less than 3 minutes or greater than 5 minutes. It is unnecessary to remain still or supine after instillation.

Answer to Question 2

D
Feedback:
Interferons interfere with the ability of viruses in infected cells to replicate and spread to uninfected cells. Interferons will not stimulate B-lymphocyte activity, stem cell multiplication, or growth of lymphoid cells.
