After opening the vial make sure that the top of it will be cleansed by an alcohol swab. Before aspirating the medication from the vial, certain amount of air should be filled in the syringe as the same amount of medication to be taken from the vial. Then inject that certain amount of air from the syringe into the vial then aspirate the medication as ordered by the doctor. This will allow easy aspiration of medication from any closed container. When a medication will be drawn or aspirated from an ampule, it is not necessary to inject air into it since it is not a closed container. The air outside the ampule will facilitate easy aspiration. Nurses’ safety is also secured that’s why a scoop method in recapping a needle is formulated. Proper disposal of needles into appropriate sharp box should be adhered to prevent needle prick injury. It is advisable to use gauze while breaking the ampule.

As mentioned earlier, make sure that you identify the patient correctly before giving the medication. Intramuscular injection can be given through the deltoid muscles (upper arm) and to the gluteal muscles (buttocks) for the adults and to the vastus lateralis (lateral side of the thigh) for the infant and young children. Cleanse the injection site with alcohol swab in circular manner from inner to outer about 1-2 inches in diameter. Then pinch the muscle and inject the needle in a quick dart manner at 90 degrees angle. Then aspirate or withdraw the plunger to check for the presence of blood in the syringe from the injection site, if there is any withdraw the needle from the muscle. Blood in the syringe upon aspiration indicates that you hit a vein thus injection should not be given. If the syringe is free from blood upon aspiration, slowly inject the medication and quickly remove the needle from the injection site or muscle. Gently massage the injection site to promote faster absorption of medication and apply slight pressure to prevent bleeding. Then apply band aid to injection site to cover the pricked skin thus infection will be prevented. Lastly do the after care of the equipment used, wash your hands and document the procedure noting the exact date, time, name, route, and amount of medication given.
