Ask the patient to press the call light if pain is present c. Schedule pain medication every 4 hours around the clock d. Offer pain medication every shift with routine medications

Myelin buildup in the central nervous system b. Demyelination and destruction of nerve fibers c. Gamma aminobutyric acid (GABA) deficiency d. Reduced acetylcholine receptors with impaired nerve impulse transmission

B. Demyelination and destruction of nerve fibers In multiple sclerosis, the myelin sheath begins to break down or degenerates as a result of the activation of the bodys immune system. The nerve becomes inflamed and edematous. Nerve impulses to the muscles slow down. As the disease progresses, sclerosis or scar tissue damages the nerve.

6. The nurse is assisting with discharging a patient with myasthenia gravis after hospitalization for severe respiratory distress. Which patient statement indicates that the nurses discharge teaching has been effective? a. If I develop muscle cramping, I can take quinine as needed. b. I have to take my Prostigmin exactly as prescribed without skipping a dose. c. I know I should take my Prostigmin as needed, whenever I feel short of breath. d. I will take my anticholinergic medication to prevent developing respiratory distress again.

B. I have to take my Prostigmin exactly as prescribed without skipping a dose With insufficient anticholinesterase medication, muscles can become weak. If respiratory muscles are affected, the patient can develop respiratory distress. C. Medication must be taken consistently to prevent weakness, not prn. A. D. Quinine and anticholinergic agents can exacerbate muscle weakness.

9. A patient diagnosed with Guillain-Barr syndrome (GBS) asks how the disease developed since the patient rarely has an illness. What nursing response is the most accurate? a. No one knows what causes it. b. It may be an autoimmune reaction to a virus. c. It most often occurs as a result of a bacterial infection. d. It is usually hereditary.

18. A patient is scheduled for a thymectomy. For which peripheral nervous system disorder should the nurse plan care for this patient? a. Multiple sclerosis (MS) b. Myasthenia gravis (MG) c. Guillain-Barr syndrome (GBS) d. Amyotrophic lateral sclerosis (ALS)

B. Myasthenia gravis (MG) No cure has been found for MG. Treatment is aimed at control of symptoms. Removal of the thymus gland (thymectomy) can decrease production of anticholinesterase (ACh) receptor antibodies and decrease symptoms in most patients.

B. Pyridostigmine (Mestinon) Steroids such as ACTH, prednisone, and other corticotropic medications are given to decrease inflammation and edema of the neuron, which may relieve some symptoms. C. Benadryl is an antihistamine. B. Pyridostigmine (Mestinon) is used in myasthenia gravis. A. Thyrotropin stimulates release of thyroid hormone.

8. A patient with amyotrophic lateral sclerosis has difficulty swallowing and copious pulmonary secretions. What equipment should the nurse ensure is at the bedside at all times? a. Tissues b. Suction c. Oxygen d. Tongue blade

B. Suction Suction is necessary in case the patient aspirates because of difficulty swallowing

14. A patient with Bells palsy has lost 10 pounds since being diagnosed. Why should the nurse plan interventions to address the risk for nutrition problems? a. Appetite is diminished. b. Taste and chewing are affected. c. Nutrients are not absorbed efficiently. d. The patient may have difficulty preparing foods.

B. Taste and chewing are affected Difficulty eating may cause the patient to eat less and lose weight

7. A mother of three young children who has a 3-year history of myasthenia gravis has had to stop helping in the childrens classrooms in the morning because of fatigue. What should the nurse say to help the patient best cope with the problem? a. You need to realize that you may not be able to do the things you used to do. b. Time your medication so that its action is peaking during the time you need the most energy. c. Getting plenty of sleep the night before you are scheduled to help will give you the stamina you need. d. If you wait to take your medication after you finish helping in the classroom, you may find that your energy level is better.

B. Time your medication so that its action is peaking during the time you need the most energy The patient should be instructed to schedule activities at times when medication is at peak action so that muscle strength is increased. A. C. These statements may also be true but medication is needed to get through an activity. D. Taking the medication after the activity will help with strength after, not during, the activity.

12. The nurse is helping a patient with trigeminal neuralgia with bathing. Which action should the nurse take when washing the patients face? a. Use hot water and antibacterial soap. b. Use lukewarm water and cotton balls. c. Use cold water to reduce inflammation. d. Use a washcloth to stimulate circulation.

Avoid crowds while on this medication. b. Take a calcium supplement while on this medication. c. Report any shortness of breath or other respiratory problems. d. Do not drive or operate machinery until the effects of the drug on you are known. e. Do not eat grapefruit, drink grapefruit juice, or consume other products containing grapefruit. f. Try to prevent constipation by adequate fluid intake, eating fiber-rich foods, and using suppositories occasionally if necessary.

C, D, F C. Report any shortness or breath or other respiratory problems D. Do not drive or operate machinery until the effects of the drug on you are known. F. Try to prevent constipation by adequate fluid intake, eating fiber-rich foods, and using suppositories occasionally if necessary

10. The nurse is providing care to a patient with Guillain-Barr syndrome. Which laboratory result should the nurse evaluate first? a. Electrolytes b. Blood urea nitrogen (BUN) c. Arterial blood gases (ABGs) d. Hemoglobin (Hgb) and hematocrit (Hct)

C. Arterial blood gases (ABGs) ABGs monitor respiratory status, which is essential in case the patients respiratory muscles become affected

5. A patient who is prescribed neostigmine (Prostigmin) for newly diagnosed myasthenia gravis (MG) asks how the medication works. What should the nurse respond to the patient? a. It is a muscle relaxant that prevents the cramping in your muscles. b. It provides potassium to your muscles so that they will contract better. c. It makes more neurotransmitter available so that your muscles can contract. d. It reduces the inflammation in your nerves so that they transmit signals better.

C. It makes more neurotransmitter available so that your muscles can contract Medications used to treat MG include the anticholinesterase (ACh) drugs neostigmine (Prostigmin) and pyridostigmine (Mestinon). These drugs improve symptoms of MG by destroying the acetylcholinesterase that breaks down

Provide a fan in the room to keep the room well ventilated.

15. The nurse is providing eye care to a patient with Bells palsy. Which nursing action is most appropriate to help protect the affected eye? a. Keep the room lights dim at all times. b. Check for pupil response twice a day. c. Request an order for ointment and a patch. d. Apply a warm moist compress to the eye three times a day.

C. Request an order for ointment and a patch Eyedrops and a patch can help keep the eye closed and protect the patients eye. D. A warm compress will not protect the eye, especially if it is only used three times a day.

13. A patient with Bells palsy is experiencing symptoms. Which symptom should the nurse address first? a. Changes in taste b. Speech difficulty c. Drooping of one side of the face d. Inability to close the affected eye

D. Inability to close the affected eye While all the problems will be disturbing to the patient, inability to close the eye could cause eye damage.
