ATI NASOGASTRIC INTUBATION
CERTIFICATION TEST FULL QUESTIONS
AND VERIFIED SOLUTIONS
●● air vent
Answer: a device or aperture that allows the entry or exit of air; on a
nasogastric tube, a branch of the main tube that is always open to the air,
providing continuous atmospheric air irrigation
●● antireflux valve
Answer: a device that can also be inserted into a lumen of some types of
nasogastric tubes to prevent the seepage of gastric contents out of the
vented lumen
●● decompression
Answer: removal of stomach contents to relieve the stomach and
intestines of pressure caused by the accumulation of gastrointestinal air
and fluid
●● gastric aspirate
Answer: a substance or material obtained by withdrawal or removal, via
a syringe and through a nasogastric, orogastric, or gastrostomy tube,
from the patient's stomach
,●● ileus
Answer: mechanical or functional obstruction of the intestines
●● lavage
Answer: therapeutic irrigation or washing out of a body cavity or part
●● lipid pneumonia
Answer: lung inflammation that develops when fat particles enter the
bronchial tree
●● methemoglobinemia
Answer: the presence of excessive methemoglobin (a non-oxygen-
carrying pigment) in the blood
●● suction pressure
Answer: the amount of negative force, measured in millimeters of
mercury, used to propel air or fluid out of a body cavity or part
●● INSERTING A NG TUBE
Answer: ...
●● -Inspect each naris for patency, noting any polyps, irritated mucosa,
or other problems that may complicate insertion. Have the patient
, breathe through one naris at a time; select the more patent naris for tube
insertion. Test the patient's gag reflex to ensure adequate swallowing if
you plan to use water during the procedure. This helps identify patients
who may be at risk for aspiration during insertion. Use water cautiously
or avoid it for patients who do not have an adequate gag reflex.
Answer: Patients may experience transient nausea as the tube's tip passes
down the back of the throat. Be sure to have the suction equipment
available in case the patient vomits. Ensure that an emesis basin and
facial tissues are within the patient's reach. Place the patient in a high-
Fowler's position and drape a towel or disposable pad across her chest to
protect her clothing and linen.
●● Determine the length of the tube to be inserted by measuring the
nasogastric tube from the tip of the patient's ear lobe to the tip of the
nose, then to the xiphoid process. When using a dual-purpose tube (one
that is used both for gastric decompression and for enteral feeding), add
10 to 12 inches to allow the distal end to reach the duodenum or
jejunum.
Answer: Mark the tubing with adhesive tape or note the striped markings
already on the tube. Lubricate the tip of the tube with water-soluble
lubricant. Encourage the patient to breathe deeply through her mouth.
Gently insert the tube into the nostril and advance it toward the posterior
pharynx. Have her tilt her head forward and encourage her to drink
water slowly. Advance the tube without using force as the patient
swallows until the desired tube length is inserted. If, at any time, the
patient experiences respiratory distress, is unable to speak, or has
significant nasal hemorrhaging or if the tube meets resistance, stop
advancing the tube and withdraw it.
