A patient inquires if this newer type of gastric analysis is going to require passage of a nasogastric tube. What is the nurse's most accurate reply?
a. "Yes, but just for the instillation of the dye."
b. "No. You take a dye orally, which will be excreted in the urine in approximately 2 hours."
c. "Yes. You will take the dye orally, and then several gastric withdrawals through the tube will show the dye."
d. "Yes. Only one withdrawal will be made through the tube, which will be treated with dye and read in approximately 2 hours."
B
Dye is given orally, and if hydrochloric acid is present, the dye will be excreted in the urine in approximately 2 hours. The older method of taking serial gastric samples every 15 minutes through a nasogastric tube may still be used.
