(passing from one medi-

constant, but when pass-

has an index of refraction
different from a vacuum,
light's speed slows.

which other blood type?
A. B- Those with an AB- blood
B. A- type should not receive
C. O- blood from those with AB+
D. AB+ blood. Although both AB+
and AB- blood have A
and B antigens, the per-
son with AB- blood lacks
a special protein, or "Rhe-
sus" Factor (Rh), circulat-
ing in their blood. If they
are given blood that has
the Rh factor present, their
body will make antibod-
ies to this foreign sub-
stance and complications
will occur. This is especial-
ly true in pregnancy situa-
tions where the mother is
Rh- and the baby she is
carrying is Rh+.
5. Which blood type is considered the universal donor? A. O-
A. O-

gen:
O- is the best donor be-
cause it does not have A, B
or Rh antigens.
AB+ is the universal re-
ceiver because it does not
have A, B or Rh antibodies.
6. What is the only artery in the body to carry oxy- D. pulmonary artery
gen-poor blood?
A. renal artery Most arteries in the body
B. interosseous artery carry oxygen-rich blood
C. vena cava away from the heart, but
D. pulmonary artery the pulmonary artery car-
ries oxygen-poor blood
from the right ventricle of
the heart to the lungs. The
vena cava would not be
correct because it is not an
artery, it is a vein and the
question asks for an artery.
7. Chocolate cysts of the ovaries are attributed to ____. D. endometriosis
A. menorrhagia
B. ectopic pregnancy Endometriosis is a con-
