How do doctors know where to inject?
Typically, people who need to self-administer injections use the vastus lateralis muscle in the thigh. To locate the correct spot, imagine dividing the thigh vertically into three equal parts. Give the injection into the outer top part of the middle section.
How can you tell the difference between an IM injection and an IV?
IV, or intravenous, injections are administered into the bloodstream either by a syringe or by a low pressure method known as a drip. The intramuscular shots are administered into the muscle, not the vein. Your muscles have a greater number of blood vessels that are also larger than the subcutaneous tissue.
What is the Z-track method of IM injection?
The Z-track method is a type of IM injection technique used to prevent tracking (leakage) of the medication into the subcutaneous tissue (underneath the skin). During the procedure, skin and tissue are pulled and held firmly while a long needle is inserted into the muscle.
What factors determine the route of administration for a drug?
The reason for choice of routes of drug administration are governing by various factors:
- Physical and chemical properties of the drug.
- Site of desired action: the action may be localised and approachable or generalised and not approachable.
- Rate of extent of absorption of the drug from different routes.
Do all nurses know how do you give injections?
While all nurses (Registered Nurses [RNs], Registered Practical Nurses [RPNs], and Nurse Practitioners [NPs]) can administer Botox, RNs and RPNs can only perform this if they have the proper authorization, such as an order or a directive, from an NP or a physician.
How do you know if the needle is in the vein?
Once you think you’re in a vein, pull the plunger back to see if blood comes into the syringe. If so, and the blood is dark red and slow moving, you know that you’ve hit a vein. You can now untie your tourniquet and proceed to inject your drugs.
What is the difference between IM and SubQ?
Subcutaneous injections (or SubQ or SC, if you like) For most folx, this is a more comfortable and less painful method than Intramuscular. Needles are relatively thin and short (typically a 25G needle, and ⅝ inches in length) since they go right underneath the skin.
Under what circumstances would you use Z-track injection?
THE Z-TRACK METHOD of I.M. injection prevents leakage of irritating and discoloring medications (such as iron dextran) into the subcutaneous tissue. It also may be used in elderly patients who have decreased muscle mass. Lateral displacement of the skin during the injection helps seal the drug in the muscle.
When would you use the Z-track method?
YOU SHOULD USE the Z-track method for all I.M. injections in adults. By leaving a zigzag path that seals the needle track, this technique prevents drug leakage into the subcutaneous tissue, helps seal the drug in the muscle, and minimizes skin irritation.
What drugs require therapeutic monitoring?

Where would an intravenous line be placed in the neck?
An intravenous line would be placed in the neck to get access to the big veins in the body (here, the superior vena cava). A picture here would be helpful:
What is Drug Administration in nursing?
Drug administration is the act in which a single dose of an identified drug is given to a patient. Drugs shall be administered in compliance with all local, state and federal laws. The nursing director is responsible for the accurate handling and precise administration of drugs to the patient.
What drugs can be given by intramuscular injection?
Some of the drugs more commonly given by this method include: chemotherapy drugs such as doxorubicin, vincristine, cisplatin, and paclitaxel antibiotics such as vancomycin, meropenem, and gentamicin antifungal drugs such as micafungin and amphotericin pain relief medications such as hydromorphone
What is the difference between IV push and IV infusion?
An IV “push” or “bolus” is a rapid injection of medication. A syringe is inserted into your catheter to quickly send a one-time dose of drug into your bloodstream. An IV infusion is a controlled administration of medication into your bloodstream over time.
