QUESTIONS AND ANSWERS
The minimum hemoglobin concentration in a fingerstick from a male blood donor is:
a. 12.0 g/dL (120 g/L)
b. 12.5 g/dL (125 g/L)
c. 13.5 g/dL (13.5 g/L)
d. 15.0 g/dL (150 g/L). ANSWER b. 12.5 g/dL (125 g/L)
All donors, regardless of sex, require a minimum hemoglobin of 12.5 g/dL (125 g/L).
The value must not be performed on an earlobe stick.
Which one of the following constitutes permanent rejection status of a donor?
a. a tattoo 5 months previously
b. recent close contact with a patient with viral hepatitis
c. 2 units of blood transfused 4 months previously
d. confirmed positive test for HBsAg 10 years previously. ANSWER d. confirmed
positive test for HBsAg 10 years previously
A positive rest for HbsAg at any time is an indefinite deferral.
,A cause for permanent deferral of blood donation is:
a. diabetes
b. residence in an endemic malaria region
c. history of jaundice of uncertain cause
d. history of therapeutic rabies vaccine.. ANSWER c. history of jaundice of uncertain
cause
Jaundice is a sign of liver impairment, which might be due to HBV or HCV. Infection
with HBV and HCV is a cause for indefinite deferral.
Below are the results of the history obtained from a prospective female blood donor:
age: 16
temp: 99.0 degree F (37.2 ˚C)
Hct: 36%
history: tetanus toxoid immunization 1 week previously
How many of the above results excludes this donor from giving blood for a routine
transfusion?
a. none
, b. 1
c. 2
d. 3. ANSWER b. 1
The Hct must be >38%. A donor may be 16 unless state law differs. Temperature
must not exceed 99.5 degrees F/37.5˚C, blood pressure must be <180mm Hg systolic
and <100mm Hg diastolic, pulse 50-100 unless an athlete (which can be lower).
Toxoids and vaccines from synthetic or killed sources have no deferral.
Prior to blood donation, the intended venipuncture site must be cleaned with a scrub
solution containing:
a. hypochlorite
b. isopropyl alcohol
c. 10% acetone
d. PVP iodine complex. ANSWER d. PVP iodine complex
The scrub must use iodine, eg, PVP iodine complex. Donors who are sensitive to
iodine can have the area cleaned with a preparation of 2% chlorhexidine and 70%
isopropyl alcohol.
All donor blood testing must include:
a. complete Rh phenotyping
