The 28-year-old female patient presents complaining of stumbling when walking, tremor, and decreased coordination. The nurse suspects the magnetic resonance imaging (MRI) scan will reveal lesions in which location?

The patient with persistent shoulder pain with associated numbness of the hand is scheduled for a magnetic resonance imaging (MRI) scan. The patient tells the nurse, "I'm terrified of enclosed spaces. I just don't know if I'll survive this test." After relaying the patient's concerns to the provider, which response does the nurse expect from the provider? 

The 23-year-old patient is brought to the emergency department after contacting emergency services to report profound weakness that started in his feet and worsened and spread cranially over the past few days. He reports severe diarrhea after a camping trip a week ago. Upon assessment, strength, sensation, and deep tendon reflexes are significantly reduced, with the lower extremities more severely affected than his upper extremities. Vital signs are normal and the patient seems to be breathing well. The nurse anticipates which finding on the lumbar puncture result?
