A 55-year-old client is unconscious, and his physician has decided to begin tube feeding him using a smallbore silicone feeding tube (Keofeed, Duo- Tube). After the tube is inserted, the nurse identifies the most reliable way to confirm appropriate placement is to:
A. Aspirate gastric contents
B. Auscultate air insufflated through the tube
C. Obtain a chest x-ray
D. Place the tip of the tube under water and observe for air bubbles
Correct Answer: C
Explanation/Reference:
Explanation:
(A) Aspiration of gastric contents is usually a reliable way to verify tube placement. However, if the client has dark respiratory secretions from bleeding, tube feedings could be mistaken for respiratory secretions; in other words, aspirating an empty stomach is less reliable in this instance. In addition, it is common for small-bore feeding tubes to collapse when suction pressure is applied. (B) Insufflation of air into large-bore nasogastric tubes can usually be clearly heard. In small-bore tubes, it is more difficult to hear air, and it is difficult to distinguish between air in the stomach and air in the esophagus. (C) A chest x-ray is the most reliable means to determine placement of small-bore nasogastric tubes. (D) Observing for air bubbles when the tip is held under water is an unreliable means to determine correct tube placement for all types of nasogastric tubes. Air may come from both the respiratory tract and the stomach, and the client who is breathing shallowly may not force air out of the tube into the water.
