Q

when do you test for TB after an exposure

A

postexposure baseline and 10 weeks after exposure

17
Q

How often should immunocompromised personnel be tested for Tb

A

at least every 6 months because immunocompromised persons may be unable to react sufficiently to the Mantoux test

18
Q

Interpretation of TST and QFT (quantiferon TB t)

baseline

A

> = 10 mm is positive; positive (only one step)

19
Q

MMR

A

live vaccine; do not give to pregnant or those who might become pregnant within 30 days

  • when should it be given postexposure
  • how long are they restricted from work
A

-all workers should have documentation of immunity
One dose subcutaneously, 2nd dose at one least one month later

A

two

23
Q

Meningococcal meningitis

which HCW should be prophylaxed after exposure

A

direct (mouth to mouth, assisting intubation, endotracheal suctioning)

Q

What is considered an exposure to HBV

A

source person is HbsAG positive or status unknown

28
Q

What should be done if exposed HCW is vaccinated for HBV, but vaccine response is unknown?

A

perform baseline test for anti-HBs

29
Q

What is protocol for HCW who is unvaccinated for HBV and has been exposed

A

begin vaccine series at time of exposure and administer hepatitis B immune globulin (HBIG) within 24 hours of exposure

30

what is average risk of transmission following percutaneous exposure

A

1.8%

31
Q

What is the postexposure prophylaxis for HCV

what should those exposed to HCV limit

A

no postexposure prophylaxis recommended

32
Q

HCW exposed to HCV should do the following

A

baseline testing for anti-HCV and ALT activity;
test for anti-HCV and ALT activity at 4 to 6 months after exposure
can test for HCV RNA 4 to 6 weeks after exposure

33
Q

HCW exposed to HIV
what to do immediately
what are intervals of followup testing

A

immediately test source and HCW to assess HIV-AB status

followup for 6 months (6 weeks, 3 months, 6 months)

34
Q

when should HIV PEP and counseling begin after exposure to HIV

within hours of exposure

35
Q

when should exposed HCW be reevaluated after exposed to HIV

A

after 72 hours

36
Q

is PEP for HIV exposure contraindicated in pregnant women

what to do immediately after exposure

A

serotest vaccinated worker to assess presence of antibody

38

A

day 10-21, furlough if inadequate titer

if symptoms develop, restrict from work and give vaccine
