A
22-year-old
man
is

to
the
critical

after
a

collision.
The

nurse
reports

hematoma.
B.

C.
epidural
hematoma. Linear
fractures
of
the
temporal
bone
frequently
disrupt

epidural
hematoma.
Patients

with
a
short
period
of
unconsciousness
followed
by
a
lucid
interval
and
then

An
epidural
hematoma
is
usually
caused
by
arterial
bleeding.
