What is the therapeutic effect of head-of-the-bed elevation and neutral head and neck
q q q q q q q q q q q q q
alignment on increased intracranial pressure (ICP)?
q q q q q
o Lowering ICP by allowing for elevations in CO2 to dilate cerebral arteries
q q q q q q q q q q q

q q q q q q q q q
obstruction Correct q
o Lowering ICP by maintaining an open airway
q q q q q q
o Lowering ICP by reducing the risk of snoring
q q q q q q q
Head-of-the-bed elevation and a neutral head position that avoids hyperextension or
q q q q q q q q q q q
hyperflexion facilitate jugular venous drainage, helping to minimize increases in ICP.
q q q q q q q q q q q
Elevated CO2 contributes to cerebral vessel vasodilation, which can increase cerebral
q q q q q q q q q q q
blood volume and further elevate ICP. Maintaining an open airway alone does not
q q q q q q q q q q q q q
minimize increases in ICP. Reducing the risk of snoring by maintaining an open airway
q q q q q q q q q q q q q q
alone does not minimize increases in ICP.

o Shunting of cerebrospinal fluid (CSF) is blocked. q q q q q q
Autoregulation is the ability of the cerebral vessels to adjust their diameter in response to
q q q q q q q q q q q q q q q
arterial pressure changes within the brain. If mean arterial blood pressure rises, cerebral
q q q q q q q q q q q q q
vessels will constrict to prevent excessive distention of the cerebral arteries. When
q q q q q q q q q q q q
autoregulation is lost, cerebral vessels are no longer able to regulate diameter and as a
q q q q q q q q q q q q q q q
result hypertension increases cerebral perfusion pressure. Cerebral vessels may become
q q q q q q q q q q
engorged as a result of the loss of autoregulation. Cerebral blood flow is affected with the
q q q q q q q q q q q q q q q q
loss of autoregulation. Loss of autoregulation does not block CSF flow.

The nurse is monitoring a patient’s intracranial pressure (ICP). While the nurse is
q q q q q q q q q q q q q
providing hygiene measures, she observes that the ICP reading is sustained at 18 mm Hg.
q q q q q q q q q q q q q q q
What is the priority nursing action?
q q q q q
o Cease stimulating the patient. Correct q q q q
o Continue with hygiene measures. q q q
o Lower the head of the bed to 10 degrees. q q q q q q q q
o Open the ICP monitor to continuous drainage.
q q q q q q
Sustained increases in ICP should be avoided. Nursing care activities should be spaced to
q q q q q q q q q q q q q q
prevent an increase in ICP. Actions that cause a sustained elevation in ICP should be
q q q q q q q q q q q q q q q
avoided until ICP returns to baseline resting values. Elevating the head of the bed to 30
q q q q q q q q q q q q q q q q
degrees or more can help reduce ICP. Continuous drainage of CSF fluid will result in
q q q q q q q q q q q q q q q
herniation.

, Herniation syndromes can be life-threatening situations. Which syndrome causes the
q q q q q q q q q q
supratentorial contents to shift downward and compress vital centers of the brainstem?
q q q q q q q q q q q
o Central herniation Correct q q
o Cingulate herniation q
o Tonsillar herniation q
o Uncal herniation q
A downward shift of the cerebral hemispheres, basal ganglia, and diencephalon through
q q q q q q q q q q q q
the tentorial notch causes central herniation, which compresses the vital centers of the
q q q q q q q q q q q q q
brainstem. This results in a shift of one cerebral hemisphere under the falx cerebri to the
q q q q q q q q q q q q q q q q
other cerebral hemisphere. Cerebellar tonsils are displaced through the foramen magnum,
q q q q q q q q q q q
causing fatal damage to the respiratory and cardiac centers. Uncal herniation compresses
q q q q q q q q q q q q
the midbrain, causing dysfunction of the ipsilateral third nerve, resulting in unilateral
q q q q q q q q q q q q
pupil dilation. q
