Increased ICP – Treatment Definition Acute Treatment Elevating head of bed to improve venous drainage. Oxygenation and ventilation to keep PaO2 >100, PaCO2 30-35, use lowest possible AW pressures to not impede venous drainage, and keep MAP at pre-intubation level. Mannitol decreases blood viscosity, CBF unchanged while CBV and ICP decrease.

Which of the following is the earliest indicator of increased ICP?
The answer is C. Mental status changes are the earliest indicator a patient is experiencing increased ICP. All the other signs and symptoms listed happen later.
How do you document a patient with increased ICP during assessment?
During the assessment of a patient with increased ICP, you note that the patient's arms are extended straight out and toes pointed downward. You will document this as: A. Decorticate posturing B. Decerebrate posturing C. Flaccid posturing The answer is B. 19. While positioning a patient in bed with increased ICP, it important to avoid?
Which patient is at risk for developing increased ICP?
12. A patient who experienced a cerebral hemorrhage is at risk for developing increased ICP. Which sign and symptom below is the EARLIEST indicator the patient is having this complication?
How to reduce ICP in patients with ICP?
Therefore, many patients with severe ICP may need to be mechanical ventilated so PaCO2 levels can be lowered (30-35), which will lead to vasoconstriction and decrease ICP (with constriction there is less blood volume and flow going to the brain and this helps decrease pressure)....remember Monro-Kellie hypothesis. 5.

Stroke (CVA) NCLEX Questions - Registered Nurse RN
Stroke (CVA) NCLEX practice questions for nursing students. A stroke is where there is decreased blood flow to brain cell tissue. This can be due to either a blockage or ruptured blood vessel. In the previous NCLEX review, I explained about other neurological disorders, so be sure to check those reviews out. As the nurse, it is important to know the pathophysiology of stroke, the types of ...
What are the three structures that alter intracranial pressure?
The answers are A, C, and D. Inside the skull are three structures that can alter intracranial pressure. They are the brain, cerebrospinal fluid (CSF), and blood. 2. The Monro-Kellie hypothesis explains the compensatory relationship among the structures in the skull that play a role with intracranial pressure.
What should a nurse do if a patient is unconscious?
If a patient is unconscious the nurse should take the patient's temperature either via the rectal, tympanic, or temporal method. Oral and axillary are not reliable. 12. A patient who experienced a cerebral hemorrhage is at risk for developing increased ICP.
Does mannitol remove water from the brain?
A. Mannitol will remove water from the brain and place it in the blood to be removed from the body. B. Mannitol will cause water and electrolyte reabsorption in the renal tubules. C. When a patient receives Mannitol the nurse must monitor the patient for both fluid volume overload and depletion.
Can a nurse administer antipyretics?
The nurse can administer antipyretics per MD order, remove extra blankets, decrease room temperature, give a cool bath or use a cooling system. Remember it is important to prevent shivering (this also increases metabolic needs and ICP). 8. A patient has a ventriculostomy.
Does mannitol cause pulmonary edema?
he answer is B. Mannitol can cause fluid volume overload that leads to heart failure and pulmonary edema. Crackles in the lung fields represent pulmonary edema and requires immediate intervention. Option A is a normal ICP reading and shows the mannitol is being effective.
What are the three structures that alter intracranial pressure?
The answers are A, C, and D. Inside the skull are three structures that can alter intracranial pressure. They are the brain, cerebrospinal fluid (CSF), and blood. 2.

What should a nurse do if a patient is unconscious?
If a patient is unconscious the nurse should take the patient’s temperature either via the rectal, tympanic, or temporal method. Oral and axillary are not reliable. 12. A patient who experienced a cerebral hemorrhage is at risk for developing increased ICP.
What is option A on nclex?
Option A is a normal ICP reading and shows the mannitol is being effective. BP is within normal limits, and dry mouth/thirst will occur with this medication because remember we are trying to dehydrate the brain to keep edema and intracranial pressure decreased. More NCLEX Quizzes.
Does mannitol remove water from the brain?
A. Mannitol will remove water from the brain and place it in the blood to be removed from the body. B. Mannitol will cause water and electrolyte reabsorption in the renal tubules. C. When a patient receives Mannitol the nurse must monitor the patient for both fluid volume overload and depletion.
What does increased ICP mean?
Increased ICP can also mean that your brain tissue itself is swelling, either from injury or from an illness such as epilepsy. Increased ICP can be the result of a brain injury, and it can also cause a brain injury. Increased ICP is a life-threatening condition. A person showing symptoms of increased ICP must get emergency medical help right away.
How to tell if ICP is increased?
nausea. vomiting. increased blood pressure. decreased mental abilities. confusion about time, and then location and people as the pressure worsens. double vision. pupils that don’t respond to changes in light.
What causes increased ICP?
Other possible causes of increased ICP include: infections. tumors. stroke. aneurysm. epilepsy. seizures. hydrocephalus, which is an accumulation of spinal fluid in the brain cavities. hypertensive brain injury, which is when uncontrolled high blood pressure leads to bleeding in the brain .
How to check cerebrospinal fluid pressure?
They may also measure the pressure of your cerebrospinal fluid using a lumbar puncture, or spinal tap. Images of the brain from a CT or MRI scan may be necessary to confirm the diagnosis.
Why is ICP increased in infants?
Increased ICP in infants can be the result of injury, such as falling off a bed, or it can be a sign of child abuse known as shaken baby syndrome, a condition in which a small child has been roughly handled to the point of brain injury.
What is increased intracranial pressure?
Increased intracranial pressure (ICP) is a rise in pressure around your brain. It may be due to an increase in the amount of fluid surrounding your brain. For example, there may be an increased amount of the cerebrospinal fluid that naturally cushions your brain or an increase in blood in the brain due to an injury or a ruptured tumor.
Can intracranial pressure cause brain damage?
Delayed treatment or failure to reduce intrac ranial pressure can cause temporary brain damage, permanent brain damage, long-term coma, or even death. The sooner you seek treatment to reduce pressure on your brain, the better the outcome. Last medically reviewed on July 12, 2017.
