Answer to Question 1
1,3,5
Rationale: While x-ray is not done prior to each feeding, it is the most effective means of assuring placement. It is usually done only after initial placement of the tube unless further confirmation is needed. Checking the pH of the aspirate might be helpful to determine if the tube is in the stomach, as pH should be 3-5, however, if the tube migrates into the bowel, pH will be alkaline, so this is not as effective as x-ray but is the best means of checking placement on a routine basis. Begin feedings slowly, and assess the client to minimize aspirate into the lungs, if there is a problem. Air insertion is highly inaccurate because a tube located high in the esophagus will still cause air to enter the stomach and could be very dangerous, leading to aspiration. Presence of the gag reflex is unrelated to checking placement.
