Physiological stress increases gluconeogenesis, requiring continued pharmacological therapy despite an inability to eat; fluids prevent dehydration, and monitoring serum glucose levels permits early intervention if necessary. Skipping the oral hypoglycemic can precipitate hyperglycemia; serum glucose levels must be monitored. Food intake should be attempted to prevent acidosis; oral hypoglycemics should be taken, and serum glucose levels should be monitored. Telling the client to eat as much as possible, increase fluid intake, and call the office again the next day are incomplete instructions; oral hypoglycemics should be taken, and serum glucose levels should be monitored. Eating as much as possible can precipitate hyperglycemia.
