- assess in 48 - 72 hours if a skin test
What are the sites for insulin?
Rotate site within one region (intrasite rotation)
- abdoment
- back of arm
- thigh
- butt
What are the sites for subcutaneous injections?

- Ventrogluteal
- Vastus lateralis
- Deltoid
What is the angle of administration for intradermal injections?
5 - 15 degrees
What is the angle of administration for insulin?
90 degrees = 2” pinch

What is the angle of administration for subcutaneous injections?
90 degrees = 2” pinch
45 degrees = 1” pinch

SC: 25 - 28
IM: 19 - 25
What happens to the diameter of the needle as the gauge size gets bigger?
Diameter gets smaller and smaller
- it’s opposite guys!
What is different about an insulin needle compared to other needles?
It’s measured in units, instead of mL
What is the volume of fluid that is injected for intradermal, insulin, SC, and IM?
Intradermal: 0.01 - 0.1 mL
Insulin: 1 - 100 UNITS
SC: < 1 mL
IM: < 3 mL (depending on the site)
Which injection do you have to aspirate on?
Intramuscular!
- as per hospital policy …
Why is the ventrogluteal site preferable?
Preferred site for medications that are larger in volume, more viscous and irritating
Where is the bevel?
Opening of the needle (at the tip)
Where is the plunger?
The thing that you push …
Where is the barrel?
Where the drug sits
Where is the needle?
If you don’t know …
Where is the shaft?
The long part of the needle (between bevel and hub)
Where is the hub?
The plastic connecting end of the needle
What parts of the needle and syringe must remain sterile when preparing a medication (6)?
- Plunger
- Luer tip of barrel
- Inside of barrel
- Needle hub
- Shaft
- Bevel
What do you put air into, an ampule or vial?
Vial
When mixing two drugs in a syringe what must you first know?
Compatability!
- CAN they be mixed?
When mixing two insulins in a syringe, which one is drawn up first?
- Regular (Humulin R) - CLEAR
2. Intermediate (NPH) - CLOUDY
What is the BEST action to take after giving an injection in order to dispose of your equipment?
Do not recap and discard the equipment in the sharps container in the patient’s room
(- put on safety lock if applicable)
What is the BEST action to take after preparing a medication?
Scoop cap
WHY do you not recap after giving an injection?
Recapping after giving an injection would NOT protect you from a needle stick injury and potential infection
- may expose you to the most frequent route of exposure to blood borne disease for heath care providers
What is the most common but preventable method of contracting blood borne illness among health care workers?
Needle stick injuries
How can we as nurses prevent infection when administering injections?
- aseptic technique
- prevent contamination of solution
- prevent needle contamination
- prepare skin
- wash hands before preparing medication
- wear gloves while administering
For needles, the higher the number, the _____ the size of the needle.
Smaller
You’ve just administered an injection, and your patient starting asking you questions. What do you do?
Go to the sharps container. ASAP!
- answer questions after
What do you do IF you have a needle stick injury?
GENTLY encourage bleeding - then wash with soap and water
- Follow BCIT policy
- Follow hospital policy
What type of syringe does Heparin go into?
TB syringe
Will a needle be contaminated if a drop of fluid runs down the needle and touches the syringe?
YES = because the needle is sterile but the syringe is not sterile
Why do you aspirate before giving an IM (as per hospital policy)?
To make sure that you’re not in a blood vessel
What do you need to do if you draw up from an ampule?
Use a draw needle WITH a filter!
- prevents glass from getting into the solution
