than bacterial meningitis and are not associated with a previous infection such as sinusitis. Fungal meningitis presents as dementia. Nonpurulent meningitis is the same as aseptic and is milder and not associated with conditions such as sinusitis.REF: p. 40927.Most causes of encephalitis are which of the following?REF: p. 40928.A 15-month-old child from Pennsylvania was brought to the ER with symptomology that includes fever, seizure activity, cranial palsies, and paralysis. Which form of encephalitis is best supported by the available assessment data?REF: p. 410, Table 16-829.A patient is newly diagnosed with multiple sclerosis (MS). What physiological change is causing the patient's symptoms?a. Depletion of dopamine in the central nervous system (CNS)ANS: BThe pathophysiology of MS includes demyelination of nerve fibers. Depletion of dopamine is related to Parkinson disease. Thedevelopment of neurofibrils is related to Alzheimer disease. Myasthenia gravis is due
b. Demyelination of nerve fibers in the CNSc. The development of neurofibril webs in the CNSd. Reduced amounts of acetylcholine at the neuromuscularjunctionto decreased amounts of acetylcholine at the junction.REF: p. 41130.When a patient asks, "What is the cause of multiple sclerosis?" the nurse bases the answer on the interaction between:REF: p. 41131.Patient teaching is considered successful regarding myasthenia gravis when the patient identifies its cause as being:a. viral infection of skeletal muscle.b. atrophy of motor neurons in the spinal cord.c. demyelination of skeletal motor neurons.d. autoimmune injury at the neuromuscular junction.ANS: DMyasthenia gravis is a disorder resulting from autoimmune injury at the neuromuscular junction, not from a viral infection. It is not due to motor neuron atrophy, but a lack of acetylcholine. Multiple sclerosis (MS) is due todemyelination of skeletal motor neurons.
