A patient is received a barium swallow test to rule out esophageal strictures and gastric ulcer. The nurse is educating the patient on what is expected post barium swallow. What statement indicates that the patient did not understand all of the teaching by the nurse?

A. "I know the barium swallow test examined my esophagus, stomach, duodenum and jejunum." The barium swallow (upper GI series) visualizes the esophagus, stomach, and duodenum, and sometimes the proximal jejunum. B. "I may need to take laxatives to prevent constipation from the barium." Barium can harden and cause constipation, so a mild laxative may be recommended. C. "My stools will be normal in color." This is the wrong statement. After a barium study, stools are typically chalky white or light-colored for 24–72 hours until all the barium is cleared. D. "I need to increase my fluid intake." Increased fluids help to flush out the barium and prevent constipation.
