b. both
c. Contaminants
d. Bacteremia
d. contaminants
T or F.
Gram-positive bacteria that are associated with true infection include
true
T or F.
Sputum cultures can be difficult to interpret because the lower respiratory
tract is colonized with bacteria, in contrast to the upper respira- tory tract,
which is typically sterile.
False
Common bacteria in uncomplicated UTIs include, except:
a. Providencia
b. Proteus
c. E. coli
d. Klebsiella
a. Providencia
T or F.
Obtaining skin cultures in infections without drainage often leads to
identification of single specific organisms that is the cause of infection.

Which of the following statements is considered incorrect regarding the
efficacy of convalescent plasma in respect to titer?
a. 2 high-titer CCP units is the minimum requirement for COVID-19 patients
b. Recovered COVID-19 patients who received a vaccine have a high CCP titers
c. Low titer and unknown CCP units may be accepted due to shortage of supply
d. NOTA
a. 2 high-titer CCP units is the minimum requirement for COVID-19 patients
Only one (1) high-titer CCP unit is the minimum requirement for COVID-19 patients since this is considered sufficient enough.
Jane Doe received the Pfizer vaccine three days ago and surprisingly did
not experience any side effects. She is scheduled for a blood donation in
an American Red Cross facility today. Will she be able to donate blood?
a. Yes, because American Red Cross has no deferral period for Pfizer
vaccine.
b. Yes, because donors are accepted any time as long as asymptomatic.
c. No, because vector-based vaccines have a deferral period for 2 weeks according to American Red Cross
d. No, because vector-based vaccines have a deferral period for 4 weeks according to American Red Cross
a. Yes, because American Red Cross has no deferral period for Pfizer
vaccine.
The deferral period for the vaccines containing inactivated viruses,
subunits of vaccines, or vaccines that do not contain live agents
and are non-replicating such as Pfizer, Moderna, Sinovac, and
Sinopharm are:
For the US FDA, ARC, and DOH NVBSP there is no deferral
time. In addition for the DOH NVBSP, the donors vaccinated
with this type of vaccine can be accepted any time as long as
they are asymptomatic.
If a person was vaccinated with Moderna and experienced moderate
symptoms due to its side effects, how long is he/she deferred from
donating according to DOH-NVBSP?
a. 4 weeks after side effects resolve
b. 2 weeks after side effects resolve
c. 14 days after side effects resolve
d. No deferral time
a. 4 weeks after side effects resolve
As indicated in the PSMID Guidelines, how long is the deferral period of a
person who received the AstraZeneca vaccine before donation, according
to DOH-NVBSP?
a. 1 month
b. 2 weeks
c. 28 days
d. no deferral time
a. 1 month
Examples of vaccines that are vector-based and contains live,
attenuated viruses are: AstraZeneca and J&J.
For the US FDA and ARC, the deferral time is 14 days or 2 weeks
after receiving the vaccine, but for DOH NVBSP, the deferral time
is 4 weeks or 1 month after vaccination.
Choose the corresponding eligibility requirements for a person to be able
to donate convalescent plasma:
a. a vaccinated patient who received any type of COVID-19 vaccine
b. a recovered COVID-19 patient who got vaccinated and had symptoms and a positive test result
c. within 6 months after complete resolution of COVID-19 symptoms
d. a recovered COVID-19 patient who received vaccine after diagnosis
e. a currently infected COVID-19 patient with high titer
b, c, d
Which of the following statements is considered incorrect regarding
convalescent plasma donation?
a. a vaccinated person is eligible to donate CCP
b. a recovered COVID-19 patient who got vaccinated is eligible to donate CCP
c. a person who received CCP is deferred for 3 months from donating
d. NOTA
a. a vaccinated person is eligible to donate CCP
