Rectus Femoris/Vastus Lateralis

Published

In my book and in the suggested videos, it mentions these two sites as two distinctive sites. However, they are found using the same landmarks and thus far, all examples I saw referenced the injection being administered to the Vastus Lateralis area (using the 'window method' of finding the greater Trocanter in the hip area and the lateral femoral condyle in the knee area and forming a 'window' with your hands, then giving the shot center/upper third portion of the muscle)...Furthermore, my text mentions the rectus femoris is one third of the way up from the condyle heading towards the trocanter, while the vastus lateralis is the middle third of that stretch.

So my question is if tonight during my compency test in lab, if they ask me to inject into the Rectus Femoris, is that injection going into the most muscular area that is in that first third section I mentioned above?

Thanks

Other random (not in particular order) notes just for myself:

-The 5 'rights' (right patient, right medication, right dose, right time/frequency, right route

-inject air into the vial before drawing medicine out (equal amount to the ordered dose of medicine)

-right injection sites for intradermal, Subcute and IM injections (IM=Deltoid, Ventrogluteral, Dorsogluteral, Vastus Lateralis, Rectus Femoris) (Subcute=subacute tissue in abdomin, side of thigh area, area near the Dorsogluteral IM location, area just distal and lateral of the Deltoid injection site, back on the shoulder blades/scapula)

-aspirate for blood for at least 5 seconds after the 'stick' but before injecting drug, then inject slowing(about 10 sec per ml)

-preferred injection site for (SC) heparin is in the abdomin, but away from the umbilical area

-plunger and needle of syringe is sterile - DO NOT TOUCH

-use needle guard for safety when transporting the needle (without snapping it permantly), then snap needle guard into permently safe position once drug is administered.

-assess skin at and around injection site

Feel free to let me know if I'm missing anything:)
