Ch.29 Gastric Intubation Flashcards
A(n) ____________ is an artificial opening into the stomach.
Gastrostomy
Gastric ____________ tubes are used exclusively to remove fluid and gas from the stomach.
Sump
Belching often indicates that the tip of the tube is still in the ____________.
Esophagus
A(n) ____________ decompression tube is inserted in the same manner as a nasogastric tube.
Nasointestinal
Intestinal tubes like the Maxter tube and the Andersen tube are weighted with ____________.
Tungsten
A(n) ____________ tube is used in an emergency to remove toxic substances that have been ingested.
Orogastric
Some nasogastric tubes have more than one ____________ within the tube.
Lumen
A gastrostomy tube is placed surgically or with the use of a(n) ____________.
Endoscope
A(n) ____________ feeding usually involves 250 to 400 mL formula per administration.
Bolus
____________ generally means the placement of a tube into a body structure.
Intubation
Identify the image.
The figure shows the method of obtaining the NEX measurement.
How is this procedure performed?
Before inserting a tube, a nurse should obtain the client’s NEX measurement (the length from the nose-to-the-earlobe-to-the-xiphoid process) and mark the tube appropriately. The first mark on the tube is made at the measured distance from the nose to the earlobe. It indicates the distance to the nasal pharynx, a location that places the tip at the back of the throat but above where the gag reflex is stimulated. A second mark is made at the point where the tube reaches the xiphoid process, indicating the depth required to reach the stomach.
Identify and label the image.
The figure shows the nasogastric intubation pathway.
What are the disadvantages of this Nasogastric intubation?
Because nasogastric tubes remain in place for several days, clients complain of discomfort in the nose and throat. If the tube’s diameter is too large or pressure from the tube is prolonged, tissue irritation or breakdown may occur. Furthermore, gastric tubes tend to dilate the esophageal sphincter, a circular muscle between the esophagus and the stomach. The stretched opening may contribute to gastric reflux, especially when the tube is used to administer liquid formula. If gastric reflux occurs, the liquid could enter the airway and interfere with respiratory function.

Why is intubation performed on clients?
Intubation basically means the placement of a tube into a body structure. Intubation is performed on a client to remove gas or fluids, or to administer liquid nourishment.
What are the problems faced with narrow-diameter feeding tubes?
Narrow tubes tend to curl during insertion because they are very flexible. Therefore, some are supplied with a stylet that helps to straighten and support it during insertion. Almost all have a weighted tip that helps the tube to descend past the stomach. Checking the placement of the distal end is more difficult; these tubes also become obstructed more easily.
What are the nurse’s functions regarding nasogastric tubes?
Usually, nurses insert nasogastric tubes. Additional nursing responsibilities include keeping the tube patent or unobstructed, implementing the prescribed use, and removing the tube when it has accomplished its therapeutic purpose.
When are tube feedings performed?
Tube feedings are used when clients have an intact stomach or intestinal function but are unconscious, have undergone extensive mouth surgery, have difficulty swallowing, or have esophageal or gastric disorders.
