1.
Why do you tap the stem of the ampule as the first step when pulling a
medication from a medication ampule? Why are you breaking the ampule AWAY from your body?
Tapping the stem of the ampule as the first step is to remove the air bubbles that may present in medication within the ampule. Bubbles can affect the accuracy amount of dosage. It is also helps to make sure
the medication can be easily transfer down to the bottom of ampule. Breaking the ampule away from the body is for safety because glass chips often fly off in various directions when breaking the ampule.
2.
What is the rationale for cleaning the top of the vial with an antimicrobial swab/solution (alcohol swab) prior to accessing the vial? Why or when would you add air to the medication vial?
Cleaning the top of the vial with alcohol swab is to avoid bacterial contamination. Add air to the medication vial is to facilitate the withdraw of the liquid medication. Helps prevent a vacuum from forming and making it easier to extract the needed amount of medication.
3.
What makes medications administered in the subcutaneous space have a slow, sustained absorption rate? Do you massage after a subcutaneous medication has been administered?
Subcutaneous tissue has few blood vessels compare to muscles or veins therefore reduce vascularity leads to a slower rate of absorption of medication. No, it is not recommended to massage after a subcutaneous medication has been administer because it may not significantly affect the absorption rate and can lead to tissue irritation or bruising. 4.
What sites are appropriate for an intradermal medication? What do you
want to be sure to avoid when selecting a site? Is the bevel up or down with an intradermal injection?
Sites are appropriate for an intradermal medication are inner surface of the forearm and upper back below the scapula. Be sure to avoid area that have lesions, rashes, moles, and scars. Also, avoid veins and blood vessels or bony areas. The bevel should be facing up to ensures that the medication is deposited to the dermal layer of the skin.
5.
What is the appropriate needle length and gauge for an intramuscular injection? What is the preferred IM site for an adult?
Needle length appropriate for an intramuscular injection for adult is range from 1 to 1.5 inches. The gauge of the needle refers to its thickness. Lower gauge numbers indicate a thicker needle. A ventrogluteal site is most used and recommended site for IM injections in adults and children of walking age.
6.
What are the three intramuscular sites? What positions make it easy to
determine anatomical landmarks for accurate site location? Please list anatomical landmarks for each of the three sites.
Three intramuscular sites: o
Ventrogluteal site: patient positioning should lie on their side or sit with the hip slightly flexed. The landmarks are patient hip bone, anterior superior iliac spine, Iliac crest.
o
Deltoid site: patient should sit or stand with the arm relaxed and hanging freely. The landmarks are acromion process and deltoid muscle.
o
Vastus Lateralis Site: Patient should lie on their back with the knee slightly bent. The landmarks are hipbone, lateral femoral condyle, midpoint between greater trochanter and lateral femoral condyle.
