Meningitis
When intracranial pressure becomes life-threatening, blood
pressure__________ , the heart rate __________, respirations
___________, and pulse pressure ____________. If the pressure is
not _____________, death will occur. Ans: Rises
Slows
Decrease
Widens
Decreased
Select the correct symptom of high brain pressure to match its
cause or the explanation of why it occurs. Ans: chart
If increased intracranial pressure is suspected, which tests
would you expect to be ordered to identify these elevated
pressures? Ans: Computed tomography (CT) scan of the head
, 3
How is the brain able to relieve high amounts of pressure that
may occur with an injury to the head? Ans: The brain is
limited and unable to reduce higher pressures without outside
intervention.
Read the case study below and then select the following signs
and symptoms consistent with increased intracranial pressure.
Ans: chart

intracranial pressure? Select all that apply. Ans: Bleeding into
the subarachnoid space
Bleeding into the subdural space
After the bicycle accident, bleeding in the brain started to
__________ the surrounding pressure. At the same time, cerebral
edema from the injury _________ the amount of _________ in the
brain, causing ___________ pressure. The brain pressure must
be ______________ for Kaylee to recover. Ans: Increase
