UNIT 3 Chapter 40 NEUROLOGICAL: Concepts of Care MS Flashcards
What is Multiple Sclerosis?
MS is characterized by demyelination (loss of myelin sheaths)
- Chronic, progressive degenerative
disease - Autoimmune
- Inflammatory
Affects the myelin sheath anywhere
along the brain, optic nerve, and
spinal cord (sensory and motor)
Pathophysiology of MS
Chronic neurologic disease that affects the brain and spinal cord due to immune- mediated demyelination and nerve injury; characterized by remissions and exacerbations
Myelin is responsible for the electrochemical transmission of impulses between the brain and spinal cord and the rest of the body; demyelination can result in slowed or stopped impulse transmission. The white fiber tracts that connect the neurons in the brain and spinal cord are also usually involved in MS.
Does MS affect more women than men?
A. No
B. Yes
B. Yes
MS affects women two to three times more often than men, suggesting a possible hormonal role in disease development. Some studies show that the disease occurs up to four times more often in women than men. However, the exact reason for this difference is not known (National Multiple Sclerosis Society, 2020).
Risk factor of Multiple Sclerosis
Modifiable
* Well water
* Low Estrogen
* Industrial and Chemical metals
* Exposure to pesticides and
herbicides
Nonmodifiable
* Familial link
* Over 40, especially over 60
* Affects men more than women
A nurse is assessing a client with a suspected diagnosis of multiple sclerosis. Which assessment findings will the nurse expect? Select all the apply.
A. Resting tremors
B. Memory loss
C. Muscle spasticity
D. Fatigue
E. Diplopia
F. Dysarthria
B. Memory loss
C. Muscle spasticity
D. Fatigue
E. Diplopia
F. Dysarthria
What is Dysarthria
difficulty speaking due to weakness in facial muscles.
- where you have difficulty speaking because the muscles you use for speech are weak
What is Diplopia?
Blurred or double vision
Signs and Symptoms of MS , name 5
Fatigue
Muscle spasticity
Blurred or double vision (diplopia)
Scotomas
Nystagmus
Paresthesias
Areflexic (flaccid) or spastic bladder
Decreased sexual function
Intention tremors
Gait changes
What would you suspect to find in a a patient with Multiple Sclerosis?
A. hyperflexibility
B. muscle contractures
C. priapism
D. diarrhea
B. muscle contractures
Spasticity is abnormal muscle tightness due to prolonged muscle contraction. I
Signs and Symptoms of Multiple Sclerosis, name 10
- Muscle weakness and spasticity
- Fatigue (usually with continuous sensitivity to temperature) * Intention tremors (tremor when performing an activity)
- Flexor muscle spasms
- Dysmetria (inability to direct or limit movement)
- Numbness or tingling sensations (paresthesia)
- Hypoalgesia (decreased sensitivity to pain)
- Ataxia (decreased motor coordination)
- Dysarthria (difficulty speaking due to slurred speech)
- Dysphagia (difficulty swallowing)
- Diplopia (double vision)
- Nystagmus (an involuntary condition in which the eyes make repetitive uncontrolled movements)
- Scotomas (changes in peripheral vision)
- Decreased visual and hearing acuity
- Tinnitus (ringing in the ears), vertigo (dizziness)
- Bowel and bladder dysfunction (flaccid or spastic)
- Alterations in sexual function, such as impotence
- Cognitive changes, such as memory loss, impaired judgment, and decreased ability to solve problems or perform calculations
- Depression
What diagnostic test is mainly used to diagnose Multiple Sclerosis?
No single specific laboratory test is definitively diagnostic for MS. However, the collective results of a variety of tests are usually conclusive. Abnormal cerebrospinal fluid (CSF) findings include elevated proteins (oligoclonal bands) and an increase in the white blood cell (WBC) count.
When a patient is getting an MRI for suspected Multiple sclerosis, what would indicate that the patient has MS?
MRI of the brain and spinal cord demonstrates the presence of plaques in at least two areas, which is considered diagnostic for MS.
Which populations is mainly affected by MS?
A, white women
B. Asian men
C. Black Women
D. Black men
A, white women
Commonly occurring disease that affects people (women twice as often as men) between the ages of 20 and 50 yr; most often affects whites of Northern European ancestry
Are patients with an autoimmune disease at risk for infections?
A. No
B. Yes
B. Yes
Nursing interventions/ Nursing teachings for patients with Multiple Sclerosis
As with any chronic disease, the client who has been diagnosed with MS is at an increased risk for infection. Teach the patient to avoid large crowds and children, who develop many infections from their classmates in school. Remind them to wash their hands frequently and use hand sanitizer when soap and water are not readily available.
