Final answer:
An incident report should be completed regardless of whether you know whose blood you were exposed to or not.
Step-by-step explanation:
The statement given, 'An incident report should only be completed if you do not know whose blood you were exposed to,' is false.
An incident report should be completed regardless of whether you know whose blood you were exposed to or not. It is an essential document used to record details of any incidents or accidents involving exposure to blood or other potentially infectious materials. Completing an incident report helps to ensure that appropriate follow-up actions can be taken to protect everyone involved and prevent future incidents.
