A child has a nasogastric (NG) tube after surgery for Hirschsprung disease. What is the purpose of the NG tube?
a. Prevent spread of infection.
b. Monitor electrolyte balance.
c. Prevent abdominal distention.
d. Maintain accurate record of output.
ANS: C
The NG tube is placed to suction out gastrointestinal secretions and prevent abdominal distention. The NG tube would not affect infection. Electrolyte content of the NG drainage can be monitored. Without the NG tube, there would be no drainage. After the NG tube is placed, it is important to maintain an accurate record of intake and output. This is not the reason for placement of the tube.
