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).

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.
Is there a cure for Multiple Sclerosis?
A. Yes
B. No
B. No
The patient with MS is treated with a variety of drugs that are used to treat and control the disease progression.
Drug therapy for Multiple Sclerosis
The patient with MS is treated with a variety of drugs that are used to treat and control the disease progression.
Many of these drugs are immunomodulators or anti-inflammatory medications that can alter immunity and place patients at risk for secondary infection.
Teach patients receiving drug therapy for MS to avoid crowds and anyone with an infection.
If signs and symptoms of an infection occur, remind them to contact their primary health care provider for prompt management and medical observation.
Examples of drugs used for treatment of relapsing types of MS include (Burcham & Rosenthal, 2019):
- Interferon-beta preparations (interferon beta-1a and beta-1b drugs), immunomodulators that modify the course of the disease and also have antiviral effects
- Glatiramer acetate, a synthetic protein that is similar to myelin-based protein
- Mitoxantrone, an IV antineoplastic anti-inflammatory agent used to resolve relapses but with risks for leukemia and cardiotoxicity
- Natalizumab, the first IV monoclonal antibody approved for MS that binds to white blood cells (WBCs) to prevent further damage to the myelin
- Fingolimod, teriflunomide, and dimethyl fumarate, newer oral immunomodulating drugs
What should you monitor for if you patient with Multiple sclerosis is prescribed an immunodialtor?
INFECTION
Patient Teaching Drug Administration Multiple Sclerosis
The interferons and glatiramer acetate are subcutaneous injections that patients can self-administer.
Teach patients how to give and rotate the site of interferon-beta and glatiramer acetate injections because local injection site (skin) reactions are common. The first dose of these drugs is given under medical supervision to monitor for allergic response, including anaphylactic shock. Teach patients receiving them to avoid crowds and people with infections because these drugs can cause bone marrow suppression. Remind them to report any sign or symptom associated with infection immediately to their primary health care provider.
Instruct patients about flulike reactions that are very common for patients receiving any of the interferons. These symptoms can be minimized by starting at a low drug dose and giving acetaminophen or ibuprofen. Adverse effects of glatiramer are not common (Burcham & Rosenthal, 2019).
Patient Teaching Multiple Sclerosis
- Teach regarding treatments
- Medications
- Minimize risk factors
- Stress, avoid infections
- Eye patch
- Safety precautions
- Prevent skin breakdowns
- Risk factors for future problems
- Respiratory failure, deteriorate over years
MS DRUG - Natalizumab
Natalizumab, a humanized monoclonal antibody, can cause many adverse events. It is usually given as an IV infusion in a specialty clinic under careful supervision. The patient is monitored carefully for allergic or anaphylactic reaction when each dose is given because the drug tends to build up in the body.
Patients receiving this drug are at risk for progressive multifocal leukoencephalopathy (PML). This opportunistic viral infection of the brain leads to death or severe disability.
Monitor for neurologic changes, especially changes in mental state, such as disorientation or acute confusion. PML is confirmed by MRI and by examining the cerebrospinal fluid for the causative pathogen (Burcham & Rosenthal, 2019). Natalizumab also causes damage to hepatic cells. Carefully monitor liver enzymes and teach patients to have frequent laboratory tests to assess for changes.
What are patients at risk for when taking Natalixumab?
A. hypotension
B. decreased liver enzymes
C. progressive multifocal leukoencephalopathy
D. hyperglycemia
Patients receiving this drug are at risk for progressive multifocal leukoencephalopathy (PML). This opportunistic viral infection of the brain leads to death or severe disability.
-Monitor for neurologic changes, especially changes in mental state, such as disorientation or acute confusion
LIVER TOXIC
Natalizumab also causes damage to hepatic cells. Carefully monitor liver enzymes and teach patients to have frequent laboratory tests to assess for changes.
MS DRUG- Mitoxantrone
Mitoxantrone, a chemotherapy drug, has been shown to be effective in reducing neurologic disability. It also decreases the frequency of clinical relapses in patients with secondary progressive, progressive-relapsing, or worsening relapsing-remi ing MS.
MS DRUG- Fingolimod
Fingolimod was the first oral immunomodulator approved for the management of MS. The capsules may be taken with or without food. Teach patients to monitor their pulse every day because the drug can cause bradycardia, especially within the first 6 hours after taking it. Two other immunomodulating drugs have been approved for MS: teriflunomide and dimethyl fumarate. Like fingolimod, these drugs inhibit immune cells and have antioxidant properties that protect brain and spinal cord cells. Teach the patient that the two most common side effects of all the oral drugs are facial flushing and GI disturbances (Burcham & Rosenthal, 2019). Remind the patient to keep follow-up appointments for laboratory monitoring of the WBC count because the oral drugs can cause a decrease in WBCs, which can predispose the patient to infection.
You are observing a new graduate nurse about to administer Findolimod to a patient whose vital signs has been unstable. The recent heart rate was 56. What is the your next.
A. encourage that she follows the health care providers ask.
B. hold the medication and contact the health care provider.
C. administer the medication yourself and observe.
D.
B. hold the medication and contact the health care provider.
The capsules may be taken with or without food. Teach patients to monitor their pulse every day because the drug can cause bradycardia, especially within the first 6 hours after taking it.
- The nurse is assessing a 48-year-old client diagnosed with multiple sclerosis. Which clinical manifestation warrants immediate intervention?
- The client has scanning speech and diplopia.
- The client has dysarthria and scotomas.
- The client has muscle weakness and spasticity.
- The client has a congested cough and
dysphagia.
- The client has a congested cough and
dysphagia.
Dysphagia is a common problem of clients diagnosed with multiple sclerosis, and this places the client at risk for aspiration pneu- monia. Some clients diagnosed with mul- tiple sclerosis eventually become immobile and are at risk for pneumonia.
The nurse enters the room of a client diagnosed with acute exacerbation of multiple sclerosis and finds the client crying. Which statement is the most therapeutic response for the nurse
to make?
1. “Why are you crying? The medication will
help the disease.”
2. “You seem upset. I will sit down and we can
talk for awhile.”
3. “Multiple sclerosis is a disease that has good
times and bad times.”
4. “I will have the chaplain come and stay with
you for a while.”
- “You seem upset. I will sit down and we can
talk for awhile.”
The nurse and a licensed practical nurse
(LPN) are caring for a group of clients. Which nursing task should not be assigned to the LPN?
1. Administer a skeletal muscle relaxant to a
client diagnosed with low back pain.
2. Discuss bowel regimen medications with the
HCP for the client on strict bedrest.
3. Draw morning blood work on the client
diagnosed with bacterial meningitis.
4. Teach self-catheterization to the client
diagnosed with multiple sclerosis.
- Teach self-catheterization to the client
diagnosed with multiple sclerosis.
