Q

things to note during a seizure

A

-beginning and ending time
-what pt was doing just before

16
Q

stroke treatment

A

-maintain open airway
-fluid and antihypertensives
-temp control
-alteplase or systemic tissue plasminogen activator and other meds
-surgical procedures

17
Q

complications of stroke

A

-extension of hemorrhage or rebleed
-seizures
-hydrocephalus
-watch pt’s closely to detect deterioration of the pt’s condition for further bleeding and rise in ICP

18
Q

what phase:
-maintain adequate airway
-establish baseline vital signs, LOC, neuromuscular function, and neurologic status
-preserve joint and muscle function
-prevent complications that may interfere with rehab

19
Q

which side is the damage:
-slow and cautious in behavior
-speech problems, aphasia
-difficulty in following verbal commands
-apraxia
-difficulty in performing simple tasks
-right-sided hemiplegia

A

left-sided brain damage

20
Q

which side is the damage:
-quick and impulsive in behavior
-short attn span
-neglects left side
-easily distracted
-left-sided hemiplegia

A

right-sided brain damage

21
Q

brain tumor can begin in four places

A

-brain itself
-meninges
-cranial nerves
-pituitary gland

22
Q

nursing management of brain tumors

A

-routine neurologic assessment, including ADL’s
-pain assessment and control

23
Q

complications of brain tumors

A

-hydrocephalus (if blood has leaked into the ventricular system, it interferes with the resorption of CSF causing hydrocephalus)
-intercerebral hemorrhage

24
Q

bacterial meningitis etiology and patho

A

-inflammation of the membranes covering the brain and spinal cord caused by an infectious agent

25
s/s of bacterial meningitis
-sudden onset of fever and severe and persistent ha greatly aggravated by moving the head -nuchal rigidity -Brudzinski sign -Kernig sign
26
viral meningitis most common viruses
enteroviruses, arboviruses, HIV, herpes simples
27
most common types of viral encephalitis caused by
herpes simples virus 1, west nile virus, enteroviruses
28
trigeminal neuralgia
-rare facial pain syndrome related to pressure on the nerve root -rarely affects both sides -extends from midline of the face across the cheek and jaw to the ear
29
trigeminal neuralgia triggers
-exposure to drafts -light touch or vibration -washing the face
30
numbness and partial or total paralysis of facial muscles edema and ischemia of facial nerve, herpes simplex virus, stress, exposure to cold, and pregnancy
bells palsy
31
Bells Palsy treatment
-patch over affected eye and artificial tears -corticosteroids and acyclovir
