Which of the following describes the functions of cerebral spinal fluid? Select
all that apply.
It protects the brain from injury.
It maintains homeostasis by regulating metabolites around the brain.
It exchanges gases with the blood to maintain oxygenation of the brain.
It collects waste products secreted by brain cells.
Which of the following is accurate about the cerebral spinal fluid circulatory
system?
It is a closed system in which there is no escape for cerebral spinal fluid under
high pressure.
Place the following layers of the skull and brain in the correct order (from
outside to inside).
Skin
Skull
Dura mater
Arachnoid mater
Subarachnoid space
,Pia mater
Brain
Which of the following can increase intracranial pressure? Select all that apply.
Excessive amounts of spinal fluid
Brain tumor
Subdural hematoma
Meningitis
When intracranial pressure becomes life-threatening, blood
pressure__________ , the heart rate __________, respirations ___________,
and pulse pressure ____________. If the pressure is not _____________, death
will occur.
Rises
Slows
Decrease
Widens
Decreased
Select the correct symptom of high brain pressure to match its cause or the
explanation of why it occurs.
chart
If increased intracranial pressure is suspected, which tests would you expect to
be ordered to identify these elevated pressures?
Computed tomography (CT) scan of the head
How is the brain able to relieve high amounts of pressure that may occur with
an injury to the head?
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.
chart
, Kaylee, (preferred pronouns: she, her), a teenager, was riding her bike when
she fell and hit her head. She was not wearing a helmet. She had abrasions on
both knees. Two hours later, she was experiencing nausea with vomiting, a
severe headache, and was mildly confused. Her pupils are dilated and slowly
react to light. The healthcare provider mentioned that Kaylee had papilledema.
Her vital signs included a blood pressure of 180/40, pulse of 45, and
respirations of 10. The temperature is 98.6 °F. She has asthma and eczema. She
was taken to the hospital for further evaluation.
Which of the following could be the cause of increased intracranial pressure?
Select all that apply.
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.
Increase
Increases
Spinal fluid
Increased
Reduced
Which of the following could reduce the risk of death for Kaylee? Select that all
apply.
Keeping the head of the bed elevated
Wearing a helmet
Surgery to remove excessive blood in the brain
Victor (preferred pronouns: he, him) is an older adult living alone. He is active,
riding his bicycle every day. He has some balance problems and sometimes
uses a cane for balance.
Which of the following things can Victor do to reduce his risk of head injury
(possibly resulting in increased intracranial pressure)? Select all that apply.
