1. 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.
2. 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.
3. 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
4. Which of the following can increase intracranial pressure? Select all that
apply.: Excessive amounts of spinal fluid
Brain tumor
Subdural hematoma
Meningitis
5. 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
6. Select the correct symptom of high brain pressure to match its cause or
the explanation of why it occurs.: *chart*
,7. 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
8. 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.
9. Read the case study below and then select the following signs and
symptoms consistent with increased intracranial pressure. : *chart*
10. 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
11. 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
12. 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
13. 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.
