A patient was just admitted to a long-term care facility from the local hospital. The patient is
being treated for psoriasis. The psoriasis does not appeaar to be responding to treatment, and
48 hours later, the IP receives a report that a CNA has developed an itchy rash. The patient's MD
visits and determines that the patient has crusted scabies and no psoriasis. Another name for
crusted scabies is?
1. American Scabies
2. Norwegian Scabies
3. Canadian Scabies
4. English Scabies - ANSWERS-2. Norwegian Scabies
Guidelines for transporting specimens include:
a. transport within 2 hours of collecting a specimen
b. transport in leakproof specimen containers and sealable leakproof bags
c. transport specimen in the syringe used to collect it
d. refrigerate all specimens prior to transport
1. a, d
2. b, c
3. a, b
4. c, d - ANSWERS-3. a, b
Which is true about a tuberculin skin test (TST)?
,1. Positive TST indicates active TB infection
2. Negative TST rules out active TB infection
3. Positive TST indicates past exposure to TB
4. Negative TST indicates past exposure to TB - ANSWERS-3. Positive TST indicates past exposure
to TB
The TST is a screening tool to detect people with latent TB infection (LTBI). It cannot be used to
rule in or rule out active TB
The optimal time to collect a sputum specimen for acid-fast bacilli (AFB) testing to rule out TB
would be:
1. First thing in the morning
2. After a respiratory tx
3. Prior to the patient going to bed
4. Prior to a respiratory tx - ANSWERS-1. First thing in the morning
A hospital has hired a new manager of the Microbiology section of the lab. During the initial
discussion with the manager about the infection prevention and control program, the IP
stresses the importance of collaboration between the departments reducing HAIs. Of the
choices below, which activity will best meet this goal?
1. the microbiology staff's compliance with the annual flu vaccination program and TST
2. the microbiology staff's participation in the periodic infection prevention educational sessions
for hospital staff
3. microbiology's prompt notification to the IP of any organism's unusual resistance pattern
4. the microbiology manager's attendance at local, state, and/or national infection prevention
and control conferences - ANSWERS-3. Microbiology's prompt notification to the IP of any
organism's unusual resistance pattern
, The primary immune response after exposure to a communicable disease pathogen or vaccine
is production of:
1. IgG
2. IgM
3. IgA
4. IgC - ANSWERS-2. IgM
IgM is the first antibody to be produced after exposure. IgG antibodies develop a few weeks
later and are a good indication of long-term immunity
When are IgM antibodies to Hepatitis A detectable in the blood?
1. within 24 hours of exposure
2. within 3 weeks of exposure
3. 30 days after exposure
4. 8-12 weeks after exposure - ANSWERS-2. Within 3 weeks of exposure
Titer declines over 4-6 weeks and and antibodies are usually not detectable after 6-12 months.
IgG remains positive lifelong, indicating immunity.
The incubation period for pertussis in immunocompetent persons is usually:
1. 7-10 days
2. 3-5 days
3. 1-2 days
4. 2-4 days - ANSWERS-1. 7-10 days
with a range of 6-21 days
