    • a) Anaphylactic Reaction (Anaphylaxis): life threatening allergic reaction that results in respiratory distress, bronchospasm, CV collapse
    • b) Antagonistic Effect: in a drug-drug reaction the combined of two or ore drugs acting simultaneously produces an effect less than that of each drug alone
    • c) Synergistic Effect: in a drug-drug reaction the combined of two or ore drugs acting simultaneously produces an effect greater than that of each drug alone
    • d) Intradermal Injection: are administered into the dermis, just below the epidermis. This route has the longest absorption time of all parenteral routes.
    • e) Subcutaneous Injection: administered into the adipose tissue layer just below the epidermis and dermis. This tissue has few blood vessels, thus sustained rate of absorption into the capillaries

    • h) Give meds separately and flush with water between each drug, some meds may interact with each other or become less effective if mixed with other drugs

    • iii) -Injection in the abdomen is absorbed most rapidly as opposed to ventral or dorsogluteal areas, which have the slowest absorption.
    • iv) -Avoid sites that are bruised, tender, hard, swollen, inflamed or scarred which can affect absorption or cause discomfort and injury
    • c) Intramuscular:
    • i) -Administers medication through the skin and subcutaneous tissues into certain muscle. Allows faster onset of action because muscles have larger and a greater number of blood vessels. It has some longer duration of effect.

    • a) Select a needle of the smallest gauge & correct length that is appropriate for the site and solution to be injected
    • b) Be sure the needle is free of medication that may irritate superficial tissues as the needle is inserted. Recommended Procedure—use two needles , one to remove the medication form the vial and a second to inject the medication. If medication is in a pre filled syringe with a non removable needle and has dripped back on the needle during preparation, gently tap the barrel to remove the excess solution
    • c) Use the Z-Track technique for IM injections to prevent leakage of medication into the needle track,
    • d) Inject into a relaxed muscle
    • e) Do Not inject to areas that feel hard or tender to the patient.
    • f) Do not administer more solution in one injection than is recommended of the site. Creates excess pressure
    • g) Inject the solution slowly so that it may be dispersed more easily into the surround tissue (10 seconds per 1 ml)
    • h) Apply gentle pressure after injection, unless contraindicated
    • i) Allow fearful patients talk about their fears and answer any questions
    • j) Rotate sites when the patient is to receive repeated injections. Same site injections may cause irritation, pain, discomfort
