A nurse is assessing a client following the insertion of an NG tube for gastric decompression. Which finding is the best indication that the procedure has achieved the desired effect?
Reduced bowel activity
A flattened or less distended abdomen
Throat discomfort
Absence of nausea
The goal of gastric decompression using an NG tube is to remove excess air and fluid from the stomach, relieving pressure and discomfort. A flattened or less distended abdomen is a clear, observable indication that this goal has been achieved. While the 'absence of nausea' could result from gastric decompression, nausea can be affected by other factors and is not as specific to the success of the procedure. 'Throat discomfort' is an expected side effect of the NG tube but does not determine that the procedure was effective. 'Reduced bowel activity' could indicate complications such as an ileus rather than an effective response to gastric decompression.
