(^226) Medical-Surgical Nursing Demystified
- Diffusion/perfusion MRI or MRA (magnetic resonance angiography) shows
vessel structure. - Single photon emission computed tomography (SPECT) shows the perfu-
sion of blood flow to a specific area of the brain. 
TREATMENT
- Surgical repair of the aneurysm.
 - Monitor level of consciousness and neurologic status.
 - Administer corticosteroid drugs to reduce inflammation:
- dexamethasone
 
 - Administer anticonvulsant drugs to reduce seizure risk due to irritation of
brain:- phenytoin, phenobarbital
 
 - Administer stool-softener drugs to decrease need to strain (straining increases
intracranial pressure):- docusate sodium
 
 - Bed rest until otherwise ordered by physician, nurse practitioner, or physi-
cian assistant. - Elevate head of bed 30 degrees.
 
NURSING DIAGNOSES
- Ineffective tissue perfusion
 - Decreased intracranial adaptive capacity
 
NURSING INTERVENTION
- Monitor the patient’s neurological function for changes—typically use
Glasgow Coma Scale or similar tool to grade response to stimuli (highest
score 15).- Eye-opening response spontaneous^4
to sound 3
to pain 2
none 1 
 - Eye-opening response spontaneous^4
