Pn2 Final Flashcards
o Mentation
Assessment:
-Level of consciousness Can be alert but not necessarily orientated: Lethargic-drowsy, awakes easily Stuporous-drowsy, difficult to wake Comatose- Unconscious, cannot wake
an overall term for diseases and conditions characterized by a decline in memory, language, problem-solving and other thinking skills that affect a person’s ability to perform everyday activities.
Memory loss is an example.
Alzheimer’s is the most common cause of this
Dementia
?? is the most common type of dementia that typically affects people older than 65 years.
Cause:
Patho:
Course of dementia:
Risk factors:
Management:
Alzheimer’s disease (AD)
Cause: Genetic and environmental factors; possibly viral
Patio: Chronic, terminal disease that is characterized by formation of neuritic plaques, neurofibrillary tangles, and vascular degeneration in the brain
Course of dementia: Steady and gradual decline of cognitive, mobility, and ADL function from mild through severe stages; patients usually die from complications of immobility
Risk factors: Female Over 65 years of age Down syndrome Traumatic brain injury
Management: Safety measures to prevent injury, wandering, or falls Cholinesterase inhibitors Behavior management ADL and mobility assistance as needed based on stage
Strokes or other vascular disorders that decrease blood flow to the brain
Stepwise progression of dementia symptoms that get significantly worse after each vascular event, such as a stroke or series of mini-strokes; symptoms may improve as collateral circulation to vital neurons develops
Male Over 65 years of age History of diabetes mellitus (DM), high cholesterol, myocardial infarction, atherosclerosis, hypertension, smoking, obesity
Identification of risk factors and management of the risk for or actual vascular event (e.g., antidiabetes drugs for DM, antihypertensive drugs, low-fat diet, smoking cessation, weight loss) Safety measures to prevent injury or falls Behavior management
Vascular dementia
also known as tic douloureux.
The trigeminal nerve has three branches:
- the first branch controls sensation in a person’s eye, upper eyelid, and forehead;
- the second branch controls sensation in the lower eyelid, cheek, nostril, upper lip, and upper gum;
- the third branch controls sensations in the jaw, lower lip, lower gum, and some of the muscles used for chewing.
According to the National Institute of Neurological Disorders and Stroke:
**trigeminal neuralgia has these characteristics:
• Affects the trigeminal (fifth cranial) nerve
- Occurs more often in people older than 50 years and in women more often than men
- *Causes a specific type of **facial pain, which results in sudden, intense facial spasms
- • Is usually provoked by minimal stimulation of a trigger zone (such as dental procedures)
- • Is unilateral (one-sided) and confined to the area innervated by the trigeminal nerve, most often the second and third branches (Fig. 44-3)
***a chronic syndrome causing impaired comfort, most often severe pain.
It can be categorized into two types of pain: classic and atypical.
**When describing trigeminal pain, patients use terms such as excruciating, sharp, shooting, piercing, burning, and jabbing.
Atypical pain descriptions may include migraine-like headache.
Between bursts of pain, which last from seconds to minutes, there is usually no pain.
Nursing considerations
Often no sensory or motor deficits are found on examination.
*Pain can be initiated by light touch, a change in facial expression (e.g., smiling), or chewing.
The fear of precipitating agonizing attacks often causes patients to avoid talking; smiling; eating; or attending to hygienic needs such as shaving, washing the face, and brushing the teeth.
The pain can cause uncontrollable facial twitching.
The course of TN involves bouts of classic pain for several weeks or months followed by spontaneous remissions.
The length of these remissions may vary from days to years, but attack-free periods tend to become shorter as the patient grows older.
The patient suspected of It usually has a CT scan and MRI to determine whether there is a reversible cause of trigeminal compression or inflammation.
The diagnosis is made based on patient history and the results of these imaging tests.
Nursing care
**The priority for care of the patient with It is pain management.
Specific interventions are determined by the amount of pain he or she is experiencing. Drug therapy is the first choice, but surgery can provide satisfactory pain relief in patients who do not respond to drug management or who experience profound adverse drug reactions.
Action Alert Teach the patient who has had percutaneous stereotactic rhizotomy to *avoid rubbing the eye on the affected side because the protective mechanism of pain will no longer warn of injury.
- Instruct him or her to inspect the eye daily for redness or irritation and report to the health care provider any change or blurred vision.
- Stress the importance of regular dental examinations because the absence of pain may not warn the patient of potential problems.
o Trigeminal neuralgia
Decreased dopamine levels, resulting in an imbalance between excitatory and inhibitory neuronal movements
o Parkinson’s Disease
Cardinal s/s of Parkinson’s
Cardinal s/s:
Tremor, muscle ridgety, bradykinesia (slow movement), masked face, drooling, dysphasia, slow shuffling gait, postural instability.
More common in men
Parkinson’s stages 1-5 Initial Mild Moderate Severe Complete
Nursing care:education
Stages:
1- Initial: unilateral limb movement, minimal weakness, hand and arm trembling-increase with stress.
2- Mild: bilateral limb movement, masklike face, slow, shuffling gait
3- Moderate: postural instability, increased shuffling gait disturbances
4- Severe: Akinesia, rigidity
5- Complete: ADL dependence
Language may be slow, slurred, rapid monotone speech.
ANS changes
No dx test
Pt./caregiver education:
- Be patient and allow extra time
- proper nutrition
- PT and OT
- medications
- fall precautions
- deep brain stimulations
- promote self esteem
- assess depression, anxiety, insomnia
Nursing care: monitor swallowing/eating, thicken foods, sit upright when eating, suction equipment available, ROM/exercise.
Changes in the brain as a result of vascular degeneration- exact cause is unknown.
o Alzheimer’s dementia

Priority is
Pt./caregiver Education:
In early stage: do what for patient?
In advanced stage: ??
Med that improves ADL ability and function/memory:
Educate care giver on burn out/fatigue:
over 65, female, Downs/TBI, genetics, PTSD/veterans.
Studies suggest that war veterans who have a current or past history of post-traumatic stress disorder (PTSD) are at an increased risk of AD and other dementias
Priority is SAFETY:
Prevent elderly abuse, support groups, medications for memory, prevent injuries r/t wandering, clutter, difficulty with transfers.
Pt./caregiver Education: Honest and open discussions Keep things familiar Consistency Don’t change rooms or furniture Reduce noise, stimulation, distractions Proper sleep/rest Memory training/reminiscence
In early stage: reorientation to reality
In advanced stage: validation therapy
Promote dependence with ADL’s Toileting program/routine Assistive devices as needed Pt. ID badge/bracelet Chair, bed alarms, video monitoring, sitter Recognize that physical behaviors may be a way of communication something Redirection techniques Wills and advanced directives/proxy/POA Door locks No reasoning, confronting, or arguing with pt. Use a calm and positive voice Wrap IV lines, avoid urinary catheters (may pull out and be confused) Diversional activities Avoid physical or chemical restraints Give short directions/few choices No scatter rugs (may cause tripping) and remove clutter Post calendars and signs Orientation Use good lighting Mark step edges with tape
Med that improves ADL ability and function/memory: Donepezil
Educate care giver on burn out/fatigue: Manage stress Find case manager early on Maintain realistic expectations Support groups Advanced directives early on Spiritual support Schedule rest time away from patient/respite Home care options Refer Alzheimer’s Association: seminars, audiovisual aids, publications, telephone support, etc.

Inflammation in the brain and spinal cord
Bacteria enters the CNS directly or via the blood stream
Bacterial-strepococcus pneumonia & meningococcal meningitis- very deadly!!
Put in what precautions ? Change in LOC may indicate what?
Viral- not as deadly but serious- can go away on its own
Labs: CSF- gold standard dx (cerebral spinal fluid) -if clear it can be viral, if cloudy and decrease glucose-bacterial
Elevated WBC and protein with both types, droplet precautions if bacterial, otherwise standard precautions.
Vaccine-??
S/s:
Keep patient in quiet, dim room, elevate HOB 30 degrees, coughing and sneezing may cause ICP, seizure precautions.
MEDS:
Dx by: Lumbar puncture
Lay how? During? After? How long?
Cryptococcal meningitis: most life threatening fungal infection in AIDS patients
s/s: headache, LOC, N/V, stiff neck, blurry vision,
preventions: handwashing, infection control
Complications: fatal; may lead to brain damage or hydrocephalus
Meningitis
- put on seizure precautions with padded rails and bed lowered to the ground. Call light.
- neuro checks every 4 hours
- Change in LOC may indicate increased ICP or hydrocyohalus
- Vitals
- Standard precautions except when bacterial by droplets
- educate family
HIB vaccine prevents
MEDS: , anticonvulsant/antibiotics may be needed, hyperosmolar agents for increased ICP, steroids, prophylaxis
S/s: headache, nuchal ridgity, neck aches, photophobia (bright light sensitivity), n/v, kernig, straight at knee, and brewvinski sign- lay on back and flex knees-if pain it indicates meningitis.
Keep patient in quiet, dim room, elevate HOB 30 degrees, coughing and sneezing may cause ICP, seizure precautions.
