Insert the needle quickly and carefully at a 45 degree angle. Holding the patient's arm with your free hand, insert the needle quickly without a big build up or dramatic countdown. Doing it quickly before the patient has the time to tense up will ensure that it happens easily and quickly.
Pull the plunger out slightly to determine whether there is blood in the syringe. If there is blood, then carefully remove the needle and find a different spot to administer the injection. If no blood is found, continue.[5]
