Answer to Question 1

B
Draw up 30 mL of normal saline or tap water in a syringe. This amount of solution will flush the length of the tube. Irrigation of a tube requires a smaller volume of solution in children: 1 to 2 mL for small tubes to 5 to 15 mL or more for large ones.

Answer to Question 2

C
Gastric fluid from a patient who has fasted for at least 4 hours usually has a pH of 5 or less.
Fluid from an enteric tube of a fasting patient usually has a pH greater than 6 . The pH of pleural fluid from the tracheobronchial tree is generally greater than 6 . Patients with continuous tube feeding may have a pH of 5 or greater.
