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?  

The patient is brought to the emergency department (ED) after being found on the floor in the garage by his wife. His right cheek balloons with each expiration and his right leg drags when he walks. While being assisted to the magnetic resonance imaging suite, the patient’s facial drooping resolves and he no longer walks with a limp. Which action does the nurse take first?

The nurse witnesses a healthy 19-year-old collapse while playing football. The individual is arousable but confused and irritable. The skin is warm, dry, and flushed.

Won’t he go into shock?”  The nurse bases the response on the need for rapid cooling to prevent which conditions? Select all that apply.
