RADTC101: Ch. 22 - Principles of Drug Administration

Ampule

Small sealed glass container that holds a single dose of parenteral solution in a sterile condition.

Angiocath

Catheter inserted directly into the vein for drug administration.

Bolus

Concentrated mass of pharmaceutical preparation.

Buccal

Pertaining to the inside of the mouth.

Drip Infusion

Infusion of liquid directly into the vein.

Enteral

Within the gastrointestinal tract.

Extravasation

Discharge or escape of fluid from a vessel into the surrounding tissue that can cause localized vasoconstriction, resulting in sloughing of tissue and tissue necrosis if not reversed with an antidote.

Intradermal

Within or between the layers of skin.

Intramuscular

Within the muscular tissue.

Intravenous

Within a vein.

Intravenous Injection

Medication that is delivered by intravenous push (rapid delivery) or intravenous infusion (slow drip of medication over a period of time) directly into a vein.

Parenteral or Parenterally

Drug administration by a route other than the GI tract, typically by injection through the skin.

Rectal

Inserted into the rectum.

Subcutaneous

Beneath the skin.

Sublingual

Beneath the tongue.

Topical

Applied to a certain area of the skin and affecting only the area to which it is applied.

Transdermal

Entering through the skin.

Venipuncture

Puncture of a vein.

Vial

Small glass bottle containing multiple doses of a drug.

Which are the appropriate methods to determine the right patient before drug administration?

b. Check patient's identification card, and ask the patient to verify name and/or date of birth.

The abbreviation for IU can be mistaken for which meaning?

b. intravenous.

Volume is measured in:

d. milliliters, cubic centimeters, and liters.

Drugs placed under the tongue are said to be administered:

b. sublingually.
(for some reason, the answers key says d. parenterally, but I think that's an error)

Drugs administered with a needle into the muscle tissue that lies beneath the subcutaneous tissue layer are called:

d. intramuscular.

This type of drug administration allows for rapid effect:

b. intravenous.

Parenteral drug administration includes all of the following routes except:

b. sublingual.

Which of the following statements express the correct relation between lumen diameter and gauge number?

c. As the diameter decreases, the gauge number increases.
(once again, I think there's an error, because the answer key says b. As the diameter decreases, the gauge number decreases)
If it helps, remember that in lab, when we draw contrast, we were suppos

Long bevel needles are generally used for:

c. subcutaneous and intramuscular injection.

Which vein is best suitable for venipuncture?

c. cephalic vein.

List the five rights of drug administration.

1. Right Drug
2. Right Amount
3. Right Patient
4. Right Time
5. Right Route
(Remember using DAPTR)

Right Drug

- Read the entire label on the drug.
- Check the name carefully.
-Check the label on the container
3 times
.
- Remember that the names of the different drugs sometimes sound similar.
- When preparing drugs for someone else,
always show the container to th

Right Amount

- To ensure that the right amount of the drug is used, it must be measured carefully and accurately.
- If drug remains,
do not put back into original container
-- dispose of according to institutional policy.
- Check the department protocol to ensure the

Right Patient

- Use the institution's protocol for patient identifiers before administering the drug.
- Ask the patient to
repeat
his or her name.
Read the patient's
identification number and MRN and/or check the patient's birth date
as it is printed on the patient's a

Right Time

- The physician or
practitioner responsible for ordering the drug usually determines the right time
for the administration of the drug.
Generally the radiographer does not determine the time, but should administer the drug at the specified time.
- Once th

Right Route

- The right route must be used.
- The
physician usually specifies the route
by which the drug should be administered.
- The radiographer must
be familiar with the terminology
associated with the most common routes.

Identify the common metric system of measurement.

- Metric system is universally used for drug administration.
- Based on units of 10.
- Units of measurement used to measure mass, volume, and length.
Meter
Liter
Gram

List the methods of drug administration.

Three classes of administration routes:
- Enteral
Oral
Rectal
Vaginal
- Parenteral
Intramuscular
Intravenous
Subcutaneous
Intradermal
- Topical

Identify the appropriate areas for drug administration.

For subcutaneous injections, needle should be at 45 degree angle.
For intramuscular injections, needle should be at 90 degree angle.
For venipuncture, most common sites include the median antecubital vein, superficial vein that lies over the cubital fossa

Prepare intravenous drugs for injection.

Intravenous drugs should always be injected at a 45 degree angle.
Intravenous drugs can be injected in one of three methods:
1.
Single administration
in which the drug is injected
slowly
.
2. Intravenous bolus or
intravenous push
(
rapid
injection).
3.

Perform venipuncture using appropriate universal precautions.

- Follow all universal precautions before attempting any parenteral drug administration.
- Wash hands.
- Check two patient identifiers.
- Explain procedure to patient an check for possible allergies.
- Assemble all needed supplies.
- Wear disposable glove

Describe documentation procedures related to drug administration.

Remember to always chart all relevant information after you've administered a drug.

Identify common standard abbreviations (the ones that were difficult for me to remember, I put in bold... honestly, I doubt we have to remember many of these)
