• Identify the appropriate syringe: – 1 ml

• Where are you going to administer this medication? – Outer aspect of abdomen (never arms)

Review – Subcutaneous Medication/Insulin

• 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

Video Review

• 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)

Intramuscular Injections (IM’s)

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

Needle Gauge

Average length:◦ Children: 5/8 – 1 inch◦ Adults: 1- 1 ½ inches

Needle length

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.

Assessment

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

Assessment

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

Prepare Medication

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

Ventrogluteal Site: #1

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

Ventrogluteal

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

Ventrogluteal con’t…

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

Vastus Lateralis site

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.

Vastus Lateralis Cont’d

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)

Deltoid site

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)

Deltoid site con’t…

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

Dorsogluteal site

Minimizes tissue irritation by sealing the drug within the muscle tissues anddecreasing pain.

Recommended technique for all IM’swhen possible

Z track Method

Z track Method

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

Implementation

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
