A nurse notices that a client's nasogastric tube is draining poorly. Which of the following is a possible cause of a poorly draining nasogastric tube?
A) A vent has been left unplugged by the nurse.
B) The drainage container is empty.
C) The tube is displaced above the cardiac sphincter.
D) The suction level (mm Hg) is higher than it should be.
C
Feedback:
Displacement above the cardiac sphincter is a possible cause of a poorly draining nasogastric tube. An unplugged vent will not cause poor drainage because often nurses remove the cap and restore the port to atmospheric pressure. A drainage container that is filled beyond capacity causes poor draining. Excessive suction does not cause poor drainage.
