ISPN考试模拟试题(111)

Question:

After a nasogastric (NG) tube has been inserted, the nurse can mostaccurately determine that the tube is in the proper place if which of the following can be demonstrated? 

1. The client is no longer gagging or coughing. 

2. The pH of the aspirated fluid is measured. 

3. Thirty milliliters of normal saline can be injected without difficulty. 

4. A whooshing sound is auscultated when 10 mL of air is inserted.



 

Measuring the pH of the aspirated gastric fluid is the most accurate determination of the placement of the NG tube. A pH lower than 4 indicates that the tube is in the stomach. Whether or not the client is gagging or coughing is not an accurate way to determine if the tube is placed correctly. No fluids should be inserted into the tube until the placement has been determined. Inserting air into the tube and listening for the resulting whoosh can be used, but this is not as accurate as pH measurement.

CN: Reduction of risk potential; CL: Evaluate

Answer: 2
