d. 7 days
Answer: d
According to the CDC, hepatitis B can
survive outside of the body for at least
7 days in dried blood on environmen-
tal surfaces or contaminated needles
and instruments. During that time, the
virus can still cause infection.
There are a couple of ways to pre-
vent this. First, all healthcare
providers should receive immuniza-
tions for all diseases that pose risks,
including hepatitis B. You also want
to make sure that the disinfectant
you're using explicitly states it's effec-
tive against hepatitis B, as well as
tuberculosis, staphylococcus,
pseudomonas, salmonella, hepatitis
C, HIV and poliovirus. Staff must
always wear personal protective
equipment while cleaning a room and
follow all manufacturers' guidelines
for the disinfectant.
3. Hospital and healthcare providers must
choose appropriate and approved disinfec-
tants as determined by the___________.
