glass containers containing medication
into the muscle.
beneath the skin layers.
into the dermis.
Parenteral (not via the gastrointestinal tract)
route requires the use of a syringe and needle, or IV catheter, to introduce medications into the body tissues or fluids.
Accuracy and care must be used
in preparing and administering any parenteral medication because errors can harm the patient.
formation of fibrous tissue or scarring.
syringe with graduated measurements to 1 mL is used to measure small dosages.
A fine 25-, 27-, or 29- gauge needle is
used at a 5- to 15- degree angle of insertion.
a bump; visible elevation of the epidermis.
Subcuatenous Route is
used for injecting medication into the tissue below the dermal layer of the skin.
A 27- gauge, 3/8- to 1/2-inch or a 25- gauge, 5/8-inch
needle is used, inserted at a 45- or 90-degree angle depending on needle length and size of individual.
IM route meds
are injected in the muscular layer. Sites are deltoid, ventrogluteal, vastus lateralis, and rectus femoris of the thigh.
Aspirate for blood,
is when you pull back on the syringe plunger to create suction.
Most 3-mL syringes have two scales:
- 1. one scale measures tenths of a milliliter (0.1mL)
- 2. minim scale
a hollow shaft fitted at the end of the syringe.
slanted part of the needle tip ending in a sharp point.
the inner part of the cannula, opening or interior diameter.
The larger the numer of gauge,
the smaller the needle.
Filter needles should used for
preparing medication from an ampule because small particles of glass may fall into the medication when the ampule neck is removed.
sticky or gummy.
solid material in the vial.
specified fluid to dissolve the solute.
a circular cut out piece that can be pushed into the bottle.
The solute must be
thoroughly mixed with the diluent before use.
Before combining two or more drugs in a syringe to save the pt the discomfort of multiple injections,

An allergy to an injectable medication
that goes into the tissue or bloodstream can have very serious consequences.
It is imperative to know what the medication
is suppose to do (therapeutic action) and what adverse/side effects may occur in order to properly assess for their presence.
All multidose vials of medication
should be dated when opened. If you see open with no date, discard.
Always follow 5 Rights when administering:
- 1. Right drug
- 2. Right route
- 3. Right dose
- 4. Right time
- 5. Right patient

the amount of solution to be injected is very small.
the quality of being hard.
SubQ Administering Heparin
- 1. sites of abdomen below costal margins to iliac crests
- 2. sites should be rotated with abd area alternating sides
- 3. DO NOT ASPIRATE increase bruising and needle movement tissue damage
- 4. do not massage after- cause bruising, bleeding, ecchymosis (purplish)
Improper site selection can result in
damage nerves, abscesses, necrosis, and sloughing of skin, as well as pain.
One mL of medication can be
safely injected into the mid-deltoid site. upper shoulder.
The vastus lateralis is the site
of choice for infants younger than 12 months for IM injections.
For children older than 13 months of age
the vastus lateralis, ventrogluteal can be used; also deltoid is appropriate unless the muscle mass is poorly developed.
It is preferable to find another way to give medication
to children because IM injections are painful and traumatic for the child.
When giving a deltoid injection to a child,
the injection should be given in the thickest part of the muscle; needle should point at a slight angle toward the shoulder.
Anaphylactic shock is
circulatory failure from an allergic reation.
a reaction characterized by reddened, slightly elevated patches known as wheals.
