The nurse is caring for a patient experiencing an acute exacerbation of multiple sclerosis (MS). Which pathophysiological change should the nurse recognize as causing the manifestations of MS? a. 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

ANS: B 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.

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.

ANS: B 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.

ANS: C 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. A. B. Dimming the lights and checking pupils will not protect the eye.

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.

ANS: C 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 ACh. A. B. This medication does not provide potassium or relax the muscles. D.

Self-care deficit: hygiene c. Pain related to inflammation of cranial nerve V d. Imbalanced nutrition: less than body requirements

ANS: C Pain takes priority. D. If pain is controlled, then the patient will be able to eat, and nutrition will not be a problem. A. Ineffective coping can be addressed after physiological problems. B. Hygiene is important but is not as high a priority as pain and nutrition.

Try to prevent constipation by adequate fluid intake, eating fiber-rich foods, and using suppositories occasionally if necessary.

ANS: C, D, F Patients taking antispasmodics such as baclofen should avoid operating machinery and driving until effects are known. Measures should be provided to prevent constipation (except dantrolene). The patient should be monitored for respiratory depression. A. B. Calcium supplements are helpful with steroids, as is avoiding crowds due to infection risk. E. There is no restriction to grapefruit with this medication.

The nurse is assisting with the administration of a Tensilon test. What response to the test causes the nurse to suspect that the patient has myasthenia gravis? a. Dyspnea develops b. Muscle cramps develop c. Muscles become very weak. d. Ptosis is temporarily improved.

ANS: D A test for myasthenia gravis involves an intravenous injection of edrophonium (Tensilon, an anticholinesterase drug).
