What do you need to know before you begin?
• Reason for primary infusion & reason for IV
med
• Drug information (expected & unexpected)

• Client’s knowledge of medication
• IV compatibility!!!

IV therapy
◦ Monitoring an IV Site, checking Infusion Rate, and
Changing an IV Solution Container
◦ Replacing IV Solution Container and Administration
Tubing

IV Medications
◦ Administrating IV Medications by Piggyback
Infusion
Order: Lovenox 40 mg SC OD
•
•
Available: 300mg/3ml (100mg/ml)
Info: Lovenox is a sterile aqueous solution containing
enoxaparin sodium, a low molecular weight heparin.
Lovenox® is indicated for the prophylaxis of deep vein
thrombosis (DVT), which may lead to pulmonary embolism
(PE)
•
How much do you withdrawl?
•
Identify the appropriate syringe:
•
Where are you going to administer this medication?
– 0.4 ml
– 1 ml
– Outer aspect of abdomen (never arms)
•
Mixing Two Insulin's in One Syringe
•
Important information you need to know?
– If insulin’s are compatible
– Is it safe to give (know clients blood sugar)
– Insulin(s) information (onset, peak, duration)
– Draw up rapid acting insulin first (unmodified)
– Check dose with RN/instructor
– Know S&S of hyper/hypoglycemia
– Injections sites

Faster absorption
Less danger of causing tissue damage
Risk of injecting into blood vessels exists
Muscle is less sensitive to irritating and viscous
drugs
Large well developed muscles (adults) can
tolerate as much as 5 ml of medication (infants
0.5-1ml, toddler 1-2ml, preschool 2-3ml,
adolescents 3-5ml)





Vastus lateralis and ventraogluteal sites
used in infants
Deltoid used in well developed children and
adolescents
In estimating needle length in children,
grasp muscle between thumb and index,
needle length showed be half the distance
between fingers.
Insert needle as close to 90 degrees as
possible
Rotate sites to decrease risk of hypertrophy


Gauge often determined by length
Most water soluble medications use:
◦ 22-27 gauge needle

More viscous medications use:
◦ 18-25 gauge needle

Older or cachectic clients may need shorter
smaller gauge needle

Average length:
◦ Children: 5/8 – 1 inch
◦ Adults: 1- 1 ½ inches



Assess integrity of a muscle prior to injection
Help client assume a position that reduces
strain on the muscle.
Area must be free of infection or necrosis,
bruising or abrasions, underlying bones,
nerves & major blood vessels.





Review order (medication rights)
Obtain medication information
Review history and assess factors
contraindicating injection (muscle atrophy,
shock, impaired circulation)
◦ What would you do if contraindicated?
Call prescriber for alternative route!
Medical history, allergies, medication
history
Client’s knowledge/concerns



6 rights, 3 checks
Prepared correct dose from vial/ampule
Replace needle with needle for injection
◦ Children: 5/8 – 1 inch
◦ Adults: 1- 1 ½ inches (22-27 gauge)
: 1 ½ inch (18-25 gauge) viscous medications


Check arm band/compare with MAR
Explain procedure, locate site, BE CONFIDENT



A deep site, situated away from major nerves
and blood vessels, less chance of
contamination in incontinent clients or
infants because it is away from rectum.
Easily identified by prominent bony
landmark.
Safe for all clients

Land marking (p. 725):
◦ Place heel of hand over the greater trochanter of
the client's hip
 right hand over left hip
 left hand over right hip






Point thumb towards client's groin
Index finger over anterior superior iliac spine
Extend middle finger back along the iliac
crest toward the buttock
Create a triangle between index finger,
middle finger and the iliac crest (towards the
buttocks)
Inject in the middle of this triangle
Flexing of the knee and hip helps person to
relax

Vastus Lateralis - lacks major nerves and
blood vessels, rapid drug absorption,
developed muscle
◦ Site used for giving children IM medication
(preferred for immunizations)
◦ Client should lie with the knee slightly flexed or in a
sitting position

Land marking (p.725):

Located on the anterior lateral aspect of the
thigh
◦ Handbreadth above the knee to a handbreadth
below the greater trochanter of the femur.
◦ In width, from the midline of the thigh to the
midline of the thighs outer side.
◦ Inject into the middle third of the muscle.




Not well developed in most adults & children
(not recommended for use in infants or
children)
Radial & ulnar nerves & brachial artery lie
within the upper arm along the humerus
Used when other injection sites are
inaccessible
Used for small amount of drugs (2 ml or less)




Landmarking (p. 726):
Expose upper arm
Palpate lower edge of the acromion process
(base of triangle)
Inject in the middle of the triangle (3-5 cm
below the acromion process)



No longer a recommended site
Runs risk of striking underlying sciatic nerve,
greater trochanter, major blood vessel.
Often used by nurses in hospitals (4 quadrant
landmarking), practice is slowly changing


Minimizes tissue irritation by sealing the
drug within the muscle tissues and
decreasing pain.
Recommended technique for all IM’s
when possible

Privacy
Wash hands
Expose only required area
Select appropriate injection site & ensure client is
comfortable
Landmark site
With nondominant hand, pull skin 2.5-3.5 cm down or
lateral (Z track), hold this position until medication is
administered.
Cleanse site with antiseptic (center and rotate outward ~
5 cm)
Gauze in nondominant hand



Remove cap (pull straight off)
Hold syringe like a dart
Inject quickly at 90 degrees
Hold lower part of syringe to stabilize syringe
Pull back on plunger 5-10 sec, if no blood inject
medication slowly (1 ml/10 sec)
Wait 10 sec, slowly withdrawl needle, place gauze
over site
Assess site
Observe response to medication
Record on MAR, record response (i.e prn/STAT)
Document and report undesirable effects
