Medical Administration 2 Flashcards
What is the tip of the needle called?
The Bevel
Name off the parts of a syringe
Plunger, barrel, needle adapter, needle hub
Do you always have to clean the top of the vial with a alcohol prep pad?
Yes
What should be used to break an ampule and how should it be broken?
A 4x4 gauze, ampule should be broken away from you
What kind of needle should be used when getting medication out of an ampule?
A filter needle
How much medication does an ampule contain?
1-10 mL
What kind of vials must be labelled with the date it was opened?
Multi-Dose Vials
What kind of syringes provide greater patient safety and reduce errors + waste?
Prefilled Syringes
Always use what technique during the preparation and administration of injections?
Aseptic Technique
Is it okay at times to administer meds from the same syringe to more than one patient?
No
Intramuscular (IM) = how many degrees?
90
Subcutaneous (SC) = how many degrees?
45
Intravenous (IV) = how many degrees?
25
Intradermal (ID) = how many degrees?
10 - 15
Injection of medication into the correct location can prevent-
Risk of injury to the tissues, nerves, blood vessels, and nodes
Parenteral =
Given via injection
What muscle is easily accessible, but not well developed in many adults?
The deltoid muscle
How many mls can the deltoid muscle take?
2 mLs or less
Injecting the deltoid muscle has potential for injury due to-
Axillary, brachial, radial, and ulnar nerves
The deltoid is used for-
Small volumes of medication + Routine immunization in adults
In order to find the deltoid muscle, you must first-
Find the acromion process (at the top bony joint of the shoulder), the injection site should be about 2 inches below it
What muscle is thick and well developed in adults?
The Vastus Lateralis Muscle
What muscle extends from a handbreadth above the knee to a handbreadth below the greater trochanter of the femur?
The Vastus Lateralis Muscle
What part of the Vastus Lateralis Muscle used for IM injections?
The middle third part
What muscle provides the greatest thickness of the gluteal muscle?
The Ventrogluteal Muscle
The Ventrogluteal Muscle is free of-
Penetrating nerves + blood vessels
The Ventrogluteal Muscle has a-
Narrower layer of fat
What is the preferred and safest site for all adults, children, and infants for larger volumes of meds + meds that are more viscous and irritating?
The Ventrogluteal Muscle
To locate the Ventrogluteal site, the heel of the hand is placed over-
The Greater Trochanter of the PT’s hip
When finding the Ventrogluteal Muscle, what 3 things are supposed to form a V-shaped triangle shape?
The index finger, the middle finger, and the iliac crest
What keeps meds from leaking out of the injection site?
The Z-Track Method
Creates a zigzag like path through tissues =
The Z-Track Method
Should the Z-Track Method be held until all medication has been administered?
Yup
For SC injections, what should be done to lower the risk of hypertrophy?
The injection sites should be rotated
What are the best sites for SC injections?
The upper arms, anterior aspects of the thighs, and abdomen
Should a SC injection be at a 90 degree angle or 45 degree angle?
Depends on amount of fatty tissue of injection site
Bevel up or down?
Up
Recap a used needle?
Never
A TB skin test = what kind of injection?
Intradermal Injection
The recommended site for TB testing for all ages =
The Forearm
ID = total amount of injectable fluid?
0.1 mL
SC = total amount of injectable fluid?
Up to 1 mL
Up to 0.5 mL (infants + small children)
IM = total amount of injectable fluid?
2-5 mL (Adults)
0.5-1 mL (Children/ infants)
Allergy testing may be performed-
Between the scapulae
When administering an Intradermal injection, older adults have decreased skin elasticity, so the skin should be-
Held taut to ensure the med is administered correctly
ID = Needle Gauge + Length?
25-27 G
3/8” to 5/8”
ID Locations?
Upper third of the forearm
Outer aspects upper arms
Between scapula
SC = Needle Gauge + Length?
25-31 G
1/2” to 5/8”
SC Locations?
Outer Upper Arms, Anterior Thighs, Upper Outer Gluteal Area, Upper Back, Abdomen
What area should be used for PTs with less SC tissue?
The Upper Abdomen
IM = Needle Gauge + Length?
18-25 G
1/2” to 1 1/2”
(Based on age/size of PT + Site used)
IM Locations?
Ventrogluteal, Vastus Lateralis, Deltoid
Preferred site for infants because it’s the most developed muscle =
Vastus Lateralis
What site is recommended adults for IM injections?
The Ventrogluteal Site
What site is recommended for vaccinations in adults?
The Deltoid Muscle
Should you ever pull back the plunger of a syringe (for 5–10 seconds) after inserting the needle, prior to injecting the medicine (Aspirate)?
Nope
