| Question | Answer |
|---|---|
| Three sites for injections | deltoid, vastus lateralis, and ventrogluteal muscles |
| Before giving injection, examine site to determine | adeuqate muscle tissue |
| Areas to avoid | lesions, trauma, inflammation, bony prominences |
| IM angle to insert needle | 90 degrees |
| IM - after puncture, do this | aspirate plunger to check for blood return |
| This confirms needle placement in muscle | lack of blood on aspiration |
| Angle to withdraw needle | angle of insertion |
| Do not _________________ site after IM injection | massage |
| If blood is withdrawn upon IM aspiration | withdraw needle and start over |
| Before injection, always check to see if patient is on | blood thinners |
| Landmarks for deltoid muscle injection | acromion process and axillary line |
| Where to insert needle in deltoid | 2-3 finger lengths below acromion process, above axillary line |
| Landmarks for vastus lateralis injection | head of greater trochanter and knee |
| Where to insert needle in vastus lateralis | middle third of muscle at least one hand width below greater trochanter and above knee |
| Landmarks for ventrogluteal injection | head of greater trochanter and anterior superior iliac spine |
| Reason to not use dorsogluteal site for injection | paralysis from sciatic nerve damage |
| What determines injection volume and needle size | age and size of patient and type of medication |
| If prescribed medication is greater than recommended dosage for particular site | Then break into smaller injections and give at different areas |
| Adult deltiod dose | 1ml |
| Contraindications for deltoid injection | infant or toddler age |
| Adult vastus lateralis dose | 3ml |
| Infant vastus lateralis dose | 1ml |
| Small infant vastus lateralis dose | 0.5ml |
| Preferred injection site for infants | vastus lateralis |
| Adult/ ventrogluteal dose | 3ml |
| Infant ventrogluteal dose | 1ml |
| Small infant ventrogluteal dose | 0.5ml |
| Toddler ventrogluteal dose | 2ml |
| Age 3 and older ventrogluteal dose | 2-3ml |
| Adolescent ventrogluteal dose | 3ml |
| Intradermal injections are used for | skin testing and administering local anesthetics |
| Sites for intradermal injections | inner forearm and upper back |
| What to avoid when giving intradermal injection | lesions and hair |
| Type of syringle for intradermal injection | tuberculin or small (1ml) |
| Angle of insertion for intradermal injection | 5-15 degrees, almost parallel to skin |
| When giving intradermal injection, make sure skin is | pulled taut |
| Bevel should be facing ____ for all injections | up |
| Intradermal injections should be given ___ | slowly |
| Watch for skin to ____________ when giving intrdermal injection | blanche and wheal |
| ___ indicates intradermal injection was given incorrectly | bleeding or absence of wheal |
| SubQ injections are used for | slow absorbing medication |
| IM injections are used for | rapid absorbing medication |
| Favored site for subQ injections | large areas that are easy for patient to reach for self-administration |
| Most commong sites for subQ injections | upper outer arm, abdomen (2in from unbilicus), anterior thigh, scapula, upper ventrodorsal gluteal |
| To prevent tissue damage from repeat injections | rotate injection sites |
| Amount to administer subQ | 1ml |
| To determine subQ needle length | equivalent to 1/2 width of skinfold from pinching tissue up from underlying muscle |
| Angle to insert subQ injection for average sized person | 45-90 degrees |
| angle to insert subQ injection for obese person | 90 degrees |
| Best subQ site for thin person | upper abdomen |
| You do not have to __________ before giving subQ injection | aspirate |
| Once subQ needle is inserted | release pinched skin and use hand to stabilize syringle |
| vastus lateralis needle size, oil-based or viscous solutions | 18-25 gauge, 1-1.5" |
| vastus lateralis needle size, aqueous solution | 22-27 gauge, 1-1.5" |
| vastus lateralis needle length for infant | 1" |
| deltoid needle size | 5/8-1" |
| ventrogluteal needle size, oil-based or viscous solutions | 18-25 gauge, 1-1.5" |
| ventrogluteal needle size, aqueous solutions | 22-27 gauge, 1-1.5" |
| infant, toddler, 3+ children ventrogluteal needle size | 21-25 gauge, 1/2-1" |
| intradermal needle size | 25-27 gauge, 3/8-5/8" |
| SubQ needle size | 25-30 gauge, 3/8-5/8" |
