C. Report the exposure to her supervisor to get PEP if it is necessary.
While cutting herself while running diagnostic tests on the blood samples, Courtney cuts herself with the scalpel. Courtney should report the exposure to her supervisor to prevent herself from messing up any further samples and to make sure that she is okay to continue work. The scalpel could have been affected by an unknown disease so she should take precautions.
I would clarify to her that it is her decision, and hers alone. If she is truly worried she might fall as a victim to the disease and has the money to afford the testing that she should most definitely go through with the testing
