Five Drug Rights
Right patient
Right drug
Right amount
Right route
Right time

What is the difference between an ampoule and a vial
vials can be used over and over again and have a rubber stopper
ampoules are single use and made of glass, filter needle must be used and the ampoule is broken for use
Why are angiocath needles preferred?
the needle retracts after usage to prevent accidental sticks

false
in what area are tissue drains placed?
in areas that tolerate the accumulation of fluid poorly
Purposes of NG tubes
diagnostic examinations

treat intestinal obstruction
control bleeding
The two most common NG tubes are:
Levin
Sump
Levin tubes are _____ lumen
single
Sump tubes are ______ lumen
double
The second lumen of the sump tube remains (inside/outside) of the patient, and is called a “______”
outside
“pigtail”
the pigtail of the sump tube does what?
controls pressure of the tube to prevent tissue damage

feedings
the nutriflex tube has what attached to its end
a mercury weighted tip
the moss tube has how many lumens (and what are their purposes?)
3

the S-B tube is ____ lumen and the patient must be continuously monitored if one is in place while a radiographer is taking images
triple lumen
3 purposes of NE tubes
decompression
diagnosis
treatment
Most common NE tubes
Cantor
Harris
Miller-Abbott
Of the three most common NE tubes, which is not single lumen?
Miller-Abbott (double lumen)
What is most important to remind the patient to do while inserting an NG/NE tube?
continuously swallow (often while drinking fluids)
What position is preferred for insertion of an NG/NE tube?
Fowler’s
What methods can be utilized to determine if an NG tube is in the correct placement?
initial radiograph
withdraw gastric fluid
use a litmus paper to test pH (3 indicates correct placement)
Patients with gastric tubes may not eat under any circumstance, unless ordered by a physician (T/F)
True
NE feeding tubes are what kind of lumen?
narrow
NE feeding tubes are inserted for the purposes of:
feeding a patient that cannot tolerate eating or taking medications through oral route, and are expected to need to be fed through this method for some time.
NE feedings/medications are given through three methods:
gravity drip

controlled pump
What tool must be close by when inserting/withdrawing an NG/NE tube?

Verify how long suction can be discontinued (time)
Verify what pressure is needed for suction
What can be inserted into a double lumen NG tube during transport
