Which of the following describes the functions of cerebral spinal fluid? Select all that apply. -
correct answer 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? - correct
answer 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). -
correct answer Skin
Skull
Dura mater
Arachnoid mater
Subarachnoid space
Pia mater
Brain
Which of the following can increase intracranial pressure? Select all that apply. - correct answer
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. - correct answer Rises
Slows
Decrease
Widens
,Decreased
Select the correct symptom of high brain pressure to match its cause or the explanation of why
it occurs. - correct answer *chart*
If increased intracranial pressure is suspected, which tests would you expect to be ordered to
identify these elevated pressures? - correct answer 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? - correct answer 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. - correct answer *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. - correct answer 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. - correct answer Increase
Increases
Spinal fluid
Increased
Reduced
Which of the following could reduce the risk of death for Kaylee? Select that all apply. - correct
answer 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. - correct answer Using a cane or
walker when ambulating
Wearing a helmet while riding his tricycle
Making sure his house has reduced clutter
Drag and drop the correct test of intracranial pressure to match its description. - correct answer
*chart*
Which could result in increased intracranial pressure? Select all that apply. - correct answer
Blood thinner medications
Skateboard Injury
Falls
Sports injury
Car accident
A case manager is seeing a patient currently in the intensive care unit. The patient has
sustained a closed head injury from a bicycle accident. In establishing the severity of the injury
to assist in discharge planning, the case manager understands that the head injury can cause
_________ to elevated intracranial pressure. In addition, as the pressure gets more severe, she
expects the patient to have a ______ blood pressure, ________ heart rate, and an increased
pulse pressure. She also expects to find ____________ edema secondary to pressure against
the optic disc. Fixed and dilated pupils might also be expected due to pressure on Cranial Nerve
______. - correct answer Vomiting
High
Low
Papilledema

Which pathophysiologic conditions can lead to seizures? Select that all apply. - correct answer
High fever
