The severely malnourished patient who abruptly exhibits confusion, oozing, and shallow breathing is likely experiencing refeeding syndrome due to the total parenteral nutrition (TPN). This patient is at risk for seizures, so the nurse’s first action is to protect the patient by instituting seizure precautions. Then, the nurse can contact the provider to obtain an order to draw an electrolyte panel. The patient might require oxygen, but the question does not indicate the patient is hypoxic. Oozing blood from the insertion site needs to be addressed, but oozing indicates a slow bleed; the patient is more at risk for injury due to seizure activity.
