Neurologic Disorders





Scenario


M.E. is a 62-year-old woman who has a 5-year history of progressive forgetfulness. She is no longer able to care for herself, has become increasingly depressed and paranoid, and recently started a fire in the kitchen. After extensive neurologic evaluation, M.E. is diagnosed as having Alzheimer’s disease. Her husband and children have come to the Alzheimer’s unit at your extended care facility for information about this disease and to discuss the possibility of placement for M.E. You reassure the family that you have experience dealing with the questions and concerns of most people in their situation.




Case Study Progress


M.E.’s husband states, “How are you going to take care of her? She wanders around all night long. She can’t find her way to the bathroom in a house she’s lived in for forty-three years. She can’t be trusted to be alone anymore; she almost burnt the house down. We’re all exhausted; there are three of us, and we can’t keep up with her.” You acknowledge how exhausted they must be from trying to keep her safe. You tell the family that there is no known treatment, but Alzheimer’s units have been created to provide a structured, safe environment for each person.





Scenario


C.B. is a single, self-supporting 58-year-old man with Guillain-Barré syndrome (GBS). He came to see his family physician in early January with symptoms of fatigue, myalgia, fever, and chills, which were accompanied by a hacking cough. He was diagnosed with viral influenza. Three weeks later, he developed bilateral weakness, numbness, and tingling of his lower extremities, which rapidly progressed into his upper body. He was brought to the emergency department after his brother recognized the seriousness of his condition. Shortly after arrival, he became totally paralyzed and required endotracheal intubation and mechanical ventilation. He was then admitted to the neurology critical care unit, where he spent 1 month. He underwent a tracheotomy before being transferred to a medical floor, where he spent several weeks. He was treated for pneumonia while hospitalized on the medical floor. His pneumonia resolved before a transfer to a skilled care facility 2 days ago for further rehabilitation and continued ventilatory support for continued neuromuscular respiratory paralysis associated with the GBS.



1. What is the etiology of GBS?


2. What type of individual is likely to be diagnosed with GBS?


3. What are the clinical manifestations of GBS?


4. Why does life-threatening respiratory dysfunction occur?


5. How is GBS diagnosed, and what tests would you expect to be performed?


6. Is the history of C.B.’s case typical?


7. What is the medical management for GBS?


8. What are the overall goals of nursing care for C.B. at this time?


9. You are concerned about the possibility of disuse syndrome related to C.B.’s paralysis. Describe an outcome of nursing care for C.B., and describe the independent nursing interventions you would implement to meet that outcome.


10. How would C.B.’s nutritional needs be maintained?


11. What evaluative parameters could you use to determine whether C.B.’s nutritional needs were being met?


12. What interventions can you implement to decrease C.B.’s fear and anxiety?




Scenario


L.C. is a 78-year-old man with a 4-year history of Parkinson’s disease (PD). He is a retired engineer, is married, and lives with his wife in a small farming community. He has four adult children who live close by. Since his last visit to the clinic 6 months ago, L.C. reports that his tremors are “about the same” as they were; however, further questioning reveals that he feels his gait is perhaps a little more unsteady, and his fatigue is slightly more noticeable. L.C. is also concerned about increased drooling. Among the medications L.C. takes are carbidopa-levodopa 25/100 mg (Sinemet), one tablet an hour before breakfast and one tablet 2 hours after lunch; carbidopa-levodopa 50/200 mg (Sinemet CR), one tablet at bedtime; and amantadine (Symmetrel) 100 mg at breakfast and bedtime. On the previous visit, he was encouraged to try taking the carbidopa-levodopa (Sinemet) more times throughout the day, but he reports that he became very somnolent with that dosing regimen. He also reports that his dyskinetic movements appear to be worse just after taking his carbidopa-levodopa (Sinemet).



1. What is parkinsonism?


2. What is PD?


3. What are the clinical manifestations of PD? Place a star next to the symptoms L.C. has mentioned.


4. L.C.’s wife asks you, “How do the doctors know L.C. has Parkinson’s disease? They never did a lot of tests on him.” How is the diagnosis of PD made?


5. L.C.’s wife comments, “I don’t even know which one of his medicines he takes for his Parkinson’s.” What medications are used for PD?


6. L.C. asks, “If I don’t have enough dopamine, then why don’t they give me a dopamine pill?” Why can’t oral dopamine be given as replacement therapy?


7. Levodopa is always given in combination with carbidopa. Why?


8. Why did L.C.’s dyskinetic movements appear to be worse just after taking his carbidopa-levodopa, and what might be done about it?


9. L.C.’s wife asks, “They can do surgery for everything else. Why can’t they do surgery to fix Parkinson’s?” How would you describe the surgical treatments available for patients with PD?


10. Because L.C. is reporting an increase in drooling, you are concerned about the possibility of his having developed a decreased ability to swallow. What further assessment could you perform to determine whether L.C. is at risk for aspirating?


11. What are three nutrition interventions that should be implemented in caring for L.C?


12. Because L.C. is reporting that his gait is more unsteady, there is an increased risk for falls. Which suggestion could you offer to diminish this risk?



13. You are giving instructions to L.C. and his wife about maintaining mobility. You determine that they understand the directions if they state that L.C. will:



14. As L.C.’s case manager, identify six things that you would need to assess to determine whether L.C. could be cared for in his home.




Scenario


N.T., a 79-year-old woman, arrived at the emergency room with expressive aphasia, left facial droop, left-sided hemiparesis, and what is presumed to be symptoms of mild dysphagia. Her husband states that when she awoke that morning at 0600, she complained of a mild headache over the right temple, was fatigued, and felt slightly weak. Thinking that it was unusual for her to have those complaints, he went to check on her and found that she was having trouble saying words and had a slight left-sided facial droop. When he helped her up from the bedside, he noticed weakness in her left hand and convinced her to come to the emergency department. Her past medical history includes paroxysmal atrial fibrillation, hypertension (HTN), hyperlipidemia, and a remote history of deep vein thrombosis. A recent cardiac stress test was normal, and her blood pressure has been well controlled. N.T. is currently taking flecainide (Tambocor), hormone replacement therapy, amlodipine (Norvasc), aspirin, simvastatin (Zocor), and lisinopril (Zestril). After a noncontrast CT scan, she is diagnosed with a thrombolytic stroke. The physician writes the following orders:




1. Outline a plan of care for implementing these orders.


2. The instructions on the tPA vials read to reconstitute with 50 mL of sterile water to make a total of 50 mg/50 mL (1 mg/mL). The hospital protocol is to infuse 0.9 mg/kg over 60 minutes with 10% of the dose given as a bolus over 1 minute. N.T. weighs 143 pounds. What is the amount of the bolus dose, in both milligrams and milliliters, that you will administer in the first minute? What is the amount of the remaining dose that you will need to administer?


3. What are the three types of cerebrovascular accidents (CVAs)?


4. What role do diagnostic tests play in evaluating N.T. for a suspected CVA?


5. Explain how the type of stroke is an important factor in planning N.T.’s care.


6. Contraindications for beginning fibrinolytic therapy include: (Select all that apply.)



7. What is the purpose of monitoring the CPK isoenzyme levels?



Case Study Progress


N.T. is admitted to the neurology unit. A second CT scan (18 hours later) reveals a small CVA in the right hemisphere. She is placed on flecainide (Tambocor), amlodipine (Norvasc), clopidogrel (Plavix), aspirin, simvastatin (Zocor), and lisinopril (Zestril).



8. If N.T.’s deficits are temporary, how long might it take before they are completely reversed?


9. While assessing N.T., you note the following findings. Which one is unrelated to the CVA?



10. Your co-worker states, “I always heard that atrial fibrillation is a precursor to stroke.” Explain whether this statement is true or false.


11. Why was N.T. placed on clopidogrel (Plavix) post-CVA?


12. Because N.T. had a thrombolytic infusion, how many hours should you wait before beginning administration of any anticoagulant or antiplatelet medications?


13. N.T. is not on hormone replacement therapy post-CVA. Why would this medication be discontinued?


14. Is there any benefit from continuing simvastatin (Zocor) after her CVA?


15. As you walk into the nurses’ station, the charge nurse is talking to N.T.’s physician, who ordered a modified barium swallow study and referral for a speech-language pathologist (SLP), occupational therapist (OT), and registered dietitian (RD). Give the rationale for these orders.


16. N.T.’s BP should be well controlled. What BP level should be considered normal for her, based on the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure?




Scenario


T.H. is a 55-year-old man with an 8-month history of progressive muscle weakness. Initially, he tripped over things and seemed to drop everything. He lost interest in activities because he was always exhausted. He sought medical assistance when his speech became slurred and he started to drool. During his initial evaluation, the physician noted frequent, severe muscle cramps; muscle twitching; and inappropriate and uncontrollable periods of laughter. After a lengthy period of diagnostic tests, T.H. received the diagnosis of amyotrophic lateral sclerosis (ALS). He is upset and bewildered about this disease that he’s “never even heard of.” You are a home health nurse who is seeing T.H. for the first time.



1. How would you explain ALS to T.H.?


2. Who gets ALS?


3. How common is ALS?


4. T.H. has many questions. He asks you, “How long can I expect to live?” How should you respond?


5. T.H. asks, “Will I slowly lose my mind?”


6. T.H. then asks, “Are there any treatments for this?”


7. T.H. thinks a moment, then says “How is the doctor even sure this is what I have?”


8. Because ALS affects so many body systems, you will be coordinating efforts with a speech, occupational, respiratory, and physical therapist, as well as a dietitian and psychologist. Define the role that each of the following professionals will play in T.H.’s treatment.


9. You hold a family meeting to recruit adequate help for the caregiver, in this case, T.H.’s spouse. Why is this important?


10. T.H. asks you, “How will the end probably come for me?” What should you tell him?


11. T.H. wants to know whether he has to be put on a “breathing machine.” What factors will you take into consideration when deciding what to tell him?




Scenario


J.B. is a 58-year-old retired postal worker who has been on your floor for several days receiving plasmapheresis every other day for myasthenia gravis (MG). About a year ago, J.B. started experiencing difficulty chewing and swallowing, diplopia, and slurring of speech, at which time he was placed on pyridostigmine (Mestinon). Before this admission, he had been relatively stable. His medical history includes hypertension (HTN) controlled with metoprolol (Lopressor) and glaucoma treated with timolol (ophthalmic preparation). Recently, J.B. was diagnosed with a sinus infection and treated with ciprofloxacin (Cipro). On admission, J.B. was unable to bear any weight or take fluids through a straw. There have been periods of exacerbation and remission since admission.




1. You note that the nursing assistive personnel has just entered these vital signs into J.B.’s record. What is your priority action at this time?


2. What treatment do you anticipate for J.B.?


3. J.B.’s wife asks you, “What may have caused my husband to get worse, and why does he keep having these episodes?” What explanation should you give her?


4. You are visiting with J.B.’s wife, who tells you she doesn’t have a lot of information about MG and she would like to know more about it so that she will feel more comfortable talking to her husband. What should you tell her?


5. J.B.’s wife asks you to explain what to expect in terms of symptoms as her husband’s illness progresses. What should you tell her?


6. J.B.’s wife asks, “How do they know that my husband has MG?” What should you tell her about how MG is diagnosed?


7. J.B.’s wife asks, “What are some options for treatment of MG?” How will you explain the different treatments?


8. List four factors that could predispose J.B. to an exacerbation of his illness.


9. J.B.’s wife asks what the physicians and nurses watch for while her husband is in the hospital. How will you explain these activities?


10. J.B.’s wife wants to know when he will be able to go home. How will you respond?


11. J.B.’s wife asks you what information she will need before taking her husband home. What will you teach her?


12. J.B.’s wife asks you, “What is the difference between a cholinergic crisis and myasthenic crisis?” What explanation should you give her?


13. You teach J.B. and his wife that the most effective means of preventing myasthenic and cholinergic crises is by:
