Final answer:
The nurse should anticipate using parenteral nutrition to meet the nutritional needs of a patient with 70% total body surface area chemical burns.
Step-by-step explanation:
In order to meet the nutritional needs of a patient with 70% total body surface area chemical burns, the nurse should anticipate using parenteral nutrition. Parenteral nutrition involves delivering nutrients directly into the bloodstream, bypassing the digestive system. This is necessary when the digestive system is not functioning properly or when the patient is unable to tolerate oral or tube feedings. By providing essential nutrients intravenously, parenteral nutrition ensures that the patient receives necessary nutrients for healing and recovery.
