Nurses should learn how to deal with food poisoning because as many as one out of 10 Americans are afflicted annually. They can identify the foodborne bacteria that infect their patients by determining the foods they ate recently, assessing their symptoms and the length of time that the symptoms developed after eating. Many cases of food poisoning go away on their own and antibiotics are needed only for traveler's diarrhea. Nurses should urge their patients to drink more fluids, then eat bland staples like cereal and gelatin. They should also encourage them to have bed rest.
