24
What is the gastrointestinal tract?
the organs that food and liquids travel through when they are swallowed, digested, absorbed, and leaves the body as feces
- examples: mouth, pharynx, esophagus, stomach, small intestine, large intestine, rectum and anus
25
What is the radiographer role in medication administration?
- check allergic history of patients

- verify patient ID
- assist the physician
- monitor the patient after medication has been given
- if state regulations permits radiographers administer and chart the medication or contrast medium
- get proper history
- document everything
26
When medications are given in the imgaing department what does the physician do?
the physician selects the drug, determines the route of administration, and prescribes the exact dosage
27
The type of orders made:
- written
- verbal
- standing order
28

SIX RIGHTS OF MEDICATION
ADMINISTRATION
-THE RIGHT DOSE
-OF THE RIGHT MEDICATION
-TO THE RIGHT PATIENT
-AT THE RIGHT TIME
-BY THE RIGHT ROUTE
-WITH THE RIGHT DOCUMENTATION
31
When preparing to administer medication the first step is to what?
verify patient identification

- check the patient's armband against the order
32
No medication should ever be given without what?
a physician's order

-ORAL
-RECTAL
-NASOGASTRIC (NG) TUBE
-MEDICATION INHALATION
-TOPICAL ROUTE
-SUBLINGUAL AND BUCCAL ROUTES
-PARENTERAL INJECTIONS

36
This type of route indicates administration of medication directly into the gastrointestinal tract
enteral route
37
the different types of enteral route
-oral
-rectal
-nasogastric (NG)
38
When a patient is severely nauseated or unable to swallow, medications can be administered by what?
by rectum
39
portions may be expelled prematurely, making dosage unreliable. An effective alternative for these patients is to administer medications and liquid nutrition through
an NG tube
40
Common and most familiar administering of medication
*dissolve in the stomach and into the small intestine absorption takes place
-digestive process can reduce therapeutic effect
Oral
41
ALTERNATIVE FOR THOSE UNABLE TO SWALLOW OR WITH
AN UNRETENTIVE STOMACH
- DOSAGE MAY BE UNRELIABLE BECAUSE OF EARLY
EXPULSION.
Rectal
41
ALSO AN ALTERNATIVE TO ORAL ADMINISTRATION
* MORE RELIABLE AND MORE EASILY CONTROLLED
Nasogastric NG tube
42
Oral medication with an enteric coating must be what
swallowed whole, not chewed, crushed, or broken
43
Provide therapy directly to lungs/respiratory system
* used in nuclear medicine for administration of radioactive gases for lung ventilation studies
- sniffing salts
- for people with asthma
Medication inhalation
44
are applied for a local effect, such as when calamine lotion is used to relieve the itch caused by poison ivy.
-MAY BE USED TO PROVIDE LOCAL THERAPY, SUCH AS
CREAMS FOR RASHES
-TRANSDERMAL PATCHES PROVIDE THERAPY BY
ADHERING MEDICATION TO THE SKIN, WHICH IS
EVENTUALLY ABSORBED INTO THE BLOODSTREAM.
ex. nicotine patches and birth control
Topical route
45
Sublingual and buccal routes are not considered what even they are placed in the mouth
they are not considered oral or enteral routes
46
-ABSORPTION THROUGH MUCOSAL TISSUES INTO THE
BLOODSTREAM
-THIS BYPASSES GI TRACT.
Topical Route Variation
47
What is use to treat angina pectoris crushing chest pain

Parenteral injections
50
medications are injected directly into the body and bypass the gastrointestinal tract
parenteral route
51
Parenteral routes administration:
-intradermal
-subcutaneous (SC)

-intra-arterial
-intravenous (IV)
-intrathecal
52
are parenteral injections administered between the layers of the skin.
Intradermal Injections
53
injections deliver medications into the fatty tissue layer beneath the skin.
Subcutaneous Injections
54
IM; into the muscle) injections are sometimes given in larger amounts than SC injections
Intramuscular injection
55
involves percutaneous access to the artery by a needle, frequently followed by catheter placement to permit injection at a specific anatomic site.
Intraarterial Administration

require the use of engineering controls to decrease the risk to health care workers from contaminated needlesticks
needleless systems
sharps with a built-in safety feature
58
the smaller the gauge size
the bigger the hole
59
never recap a what
dirty needle
60
READ THE MEDICATION LABEL THREE TIMES BEFORE
ADMINISTRATION: Parenteral administration
1. when selecting the container
2. while preparing the dose
3. just before injection
* this is essential to be absolutely certain you have the correct drug and the proper strength, and that the expiration date has not been exceeded
61
Parenteral Injection Procedure
* Greet the patient. Check patient identification and explain the procedure.
* Select the appropriate injection site.
* Perform hand hygiene and don clean gloves.
* Cleanse the selected area with an alcohol wipe.
* Hold the skin taut with your nondominant hand.
* Insert the needle at the correct angle, and pull back slightly on the plunger.
* If no blood is present, inject the medication.
* Withdraw the needle quickly, and wipe the injection site.
* Place the syringe with attached needle in a sharps container.
* See to the patient’s comfort.
* Remove your gloves and perform hand hygiene.
* Chart the medication.
* Discard the container and any remaining medication
62

77
bolus injection is also known as
IV push
78
what happens if the bag is placed too low
IF THE BAG IS PLACED LOWER THAN THE VEIN, BLOOD WILL FLOW BACK
INTO THE CATHETER OR TUBING AND MAY CLOT, CAUSING THE FLUID TO
STOP FLOWING.
78
How high should an IV bag be above the vein
18 to 20 inches
78
If the injection site is cool, swollen, and boggy the iv solution is what
may have infiltrated
78
what happens if the bag is too high
AN IV SOLUTION THAT IS TOO HIGH MAY CAUSE FLUID TO INFILTRATE
INTO THE SURROUNDING TISSUES BECAUSE OF THE INCREASED
HYDROSTATIC PRESSURE.
79
PAINFUL AND OFTEN DANGEROUS CONDITION
TREATMENT IS TO APPLY COLD PACKS TO THE SITE.
INCIDENT REPORT MUST BE FILED.
Extravasation
79
what do you do if there is infiltration /extravasation
apply cold packs

agents that cause blistering if infiltrated into subcutaneous tissue
vesicants
80
steps for DISCONTINUING AN IV
PERFORM HAND HYGIENE AND DON GLOVES.
* EXPLAIN PROCEDURE TO PATIENT.
* CLOSE THE DRIP CONTROL.
* GENTLY REMOVE ADHESIVE TAPE AROUND
CATHETER TO EXPOSE VEIN.
* REMOVE CATHETER WITH A SINGLE LONG,
SMOOTH PULL.
* CHECK TIP TO ENSURE IT IS INTACT.
* APPLY PRESSURE TO SITE WITH DRY COTTON
BALL OR GAUZE FOR 1 MINUTE.
* APPLY STERILE ADHESIVE BANDAGE OR TAPE
COTTON BALL TO SITE.

83
radiographers who chart medications must use the exact procedure established by the institution
Charting medications
83
Monitoring IV fluids
* CALL IN ADVANCE TO INFORM THE NURSE OF LENGTHY
PROCEDURES.
* PLUG IN THE PUMP RATHER THAN RELYING ON BATTERY
POWER.
* WATCH IV FLUID LEVELS, AND ALLOW TIME FOR
REPLACEMENT BEFORE THE IV FLUID IS EXHAUSTED.
* IF AN IV SET RUNS OUT, OR IF THE ALARM SOUNDS, CALL
THE NURSING SERVICE IMMEDIATELY RATHER THAN
WAITING UNTIL THE PATIENT IS RETURNED TO THE
NURSING UNIT.
