A 48-Year-Old Woman with a History of Repeated Vomiting Was $23 \mathrm{in} .(57.5 \mathrm{~cm}$

A 48-year-old woman with a history of repeated vomiting was admitted to the hospital with a diagnosis of large bowel obstruction. To decompress the stomach a nasogastric tube was passed.
-When passing a nasogastric tube some important anatomic facts should be considered except which?

A) The well-lubricated tube is inserted through the wider nostril.
B) The tube is directed backward along the nasal floor and not upward because it may become caught on the nasal choanae.
C) The distance between the nostril and the cardiac orifice of the stomach is about $23 \mathrm{in} .(57.5 \mathrm{~cm}$ ) .
D) The distance between the cardiac orifice and the pylorus is 4.8 to $5.6 \mathrm{in}$ . (12 to $14 \mathrm{~cm}$ ) .
E) Esophageal narrowing may offer resistance to the tube behind the cricoid cartilage, 7.2 in. $(18 \mathrm{~cm})$ from the nostril.
F) The left bronchus and the arch of the aorta cross in front of the esophagus and may impede the descent of the tube, $11.2 \mathrm{in}$ . $(28 \mathrm{~cm})$ from the nostril.
G) Where the esophagus enters the stomach there is a slight resistance to the descent of the tube.
