Graded A+
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.

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.
