MULTIPLE CHOICE
1. Nasogastric (NG) tubes are inserted with the patient in the position.
b. high Fowler
Nasogastric (NG) tubes are plastic or rubber tubes inserted through the nasopharynx into the
stomach. The patient is placed in a high Fowler position with pillows supporting the head
and shoulders.
2. NG tubes are inserted through the patient’s blank with the end of the tube placed in the
blank .
b. nasopharynx; stomach
NG tubes are inserted through the patient’s nasopharynx with the end of the tube placed in
the stomach
.
NG tubes are plastic or rubber tubes inserted through the nasopharynx into the stomach. The
primary use of an NG tube is for administration of medications and gastric decompression
or removal of flatus and fluids from the stomach after intestinal obstruction or major trauma.
3. To facilitate removal of a nasogastric tube, the patient is .
b. encouraged to take a deep breath.
Identify the patient and explain the procedure. Verify that consent for the procedure has been
obtained. Wash your hands and then turn off and disconnect the suction equipment if it is in
place. Put on clean gloves and instruct the patient to take in a deep breath as the tube is
gently withdrawn.
4. The most common type of nasogastric tube used for stomach decompression is the .
d. single-lumen Levin tube.
The most common NG tube used for gastric decompression is the Levin tube, which is a
single-lumen tube with several holes near its tip.
5. To confirm the placement of an NG tube in its proper position, a physician may use, answer
is .
d. both a and b.
, a. a syringe to remove gastric contents as proof.
b. fluoroscopy or radiography for visualization.
Verification of tube placement can be obtained through a variety of methods, including
fluoroscopy. Additionally, the physician may use a stethoscope to listen for gastric sounds
and, with a syringe, aspirate back gastric contents into an emesis basin.
6. When transporting a patient with a NG tube to medical imaging,
d. do all of the above.
1 . confirm the suction pressure before disconnecting the tube.
2 . make sure the NG tube is secured to the patient’s nose.
3 . confirm the allowable time for suction interruption.
If a patient is to be transferred, then the radiologic technologist must first confirm that the
physician has given an order allowing the transfer and interruption of suctioning. The length
of time that suction can be interrupted safely also must be known as well as the level of
suction pressure required.
7. As you arrive into a patient’s room for transport to radiology, you notice that the patient has
an NG tube in place with a syringe upright and pinned to the gown. You should know that
this patient
a. has a double-lumen NG tube in place.
To prevent leakage from a double-lumen type NG tube, the barrel of a piston-like syringe
may be inserted into the suction-drainage lumen, and it is then pinned to the patient’s gown
with the barrel upward. A double-lumen tube must never be clamped closed because to do so
might cause the lumina to adhere to each other and destroy the double-lumen effect.
8. When working with a nonambulatory male patient who needs to void,
e. do all of the above.
1 . ask the patient how much assistance he feels he needs and allow him to use a
urinal.
2 . after the patient has voided, record the volume of urine in the patient’s chart if
documentation is required.
3 . dispose of the urine in the toilet and rinse the urinal with cold water.
4 . remove your disposable gloves, wash your hands, and place the soiled urinal in a
receptacle for resterilization.
