Question 1

Postexposure prophylaxis for bloodborne pathogen exposure may include:

A)Use of antiretroviral drugs
B)Use of HIV vaccines
C)Use of hepatitis A vaccine
D)Waiting for treatment until symptoms appear

Answer 1

A
The health-care provider working with an employee after bloodborne pathogen exposure will decide whether the use of antiretroviral drugs is warranted based on the amount of exposure and the medical history of the employee and the patient.

Question 2

There are many viruses capable of causing disease that are not bloodborne.

Question 3

Which is not a type of hazard encountered in a typical medical laboratory environment?
