|\ |\ |\ |\
d. 15.0 g/dL (150 g/L) - CORRECT ANSWERS ✔✔b. 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.

|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
indefinite deferral. |\

|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
infection and is still taking antibiotics - CORRECT ANSWERS ✔✔c.

|\ |\ |\ |\ |\ |\ |\ |\ |\
A donor is acceptable if she has not been pregnant in the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
previous 6 weeks. |\ |\
Below are the results of the history obtained from a prospective
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
female blood donor: |\ |\
Age: 16 |\
Temperature: 99.0"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 - CORRECT ANSWERS ✔✔b. The Hct must be >38%, A donor
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
may be l6 unless state law differs. Temperature must not exceed
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
99.5°C/37.5°C, blood pressure must be <180 mmHg systolic and |\ |\ |\ |\ |\ |\ |\ |\ |\
<100 mmHg diastolic, pulse 50-100 unless an athlete (which can
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
be lower). Toxoids and vaccines from synthetic or killed sources
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
have no deferral. |\ |\
For apheresis donors who donate platelets more frequently than
|\ |\ |\ |\ |\ |\ |\ |\ |\
