Syringe Flashcards
What angle should you use an insulin pen?
90 degrees.
What is the difference between a Luer-Lok and and a non-Luer-Lok syringe?
A Luer-Lok syringe has a tip that requires needles to be twisted onto it to avoid accidental removal of the needle. A non-Luer-Lok syringe has a smooth graduated tip and needles are slipped into it and can be used for irrigation of tubes or wounds without the needle.
What’s one thing you must do to achieve the right dosage in prefilled unit dose systems?
Excess medication must be ejected.
The gauge varies from #18 - #30. What do the gauge numbers mean?
The larger the gauge number, the smaller the diameter of the shaft and vice versa.
Why do we use smaller gauges?
Why do we use larger gauges?
Smaller gauges produce less tissue trauma.
Larger gauges are necessary for viscous medications, such as penicillin.
What’s the difference between a passive safety device and an active safety device?
Passive safety devices automatically retracts the needle into the barrel after injection.
Active safety devices requires the nurse to manually activate the safety feature and sheathe the needle.
What should you consider about the needle when drawing medicine from an ampule?
You should always use a filter needle to prevent glass particles from entering the syringe. You could also use a filter straw.
What should you do to administer powdered medications?
You need to reconstitute the drug, which means adding a liquid (diluent) to the powdered medication.
What do you need to do to make drawing medicine out of a vial easier? Why do we do this?
You need to put air into the vial equal to the amount of medicine you’re going to draw out. This is to make sure there will be no negative pressure inside the vial when drawing the medicine.
What do you need to make sure you do when injecting air into a vial and why do you do this?
Make sure to keep the bevel above the medicine to avoid creating air bubbles in the medicine.
When giving subcutaneous injection sites, why do they need to be rotated?
To minimize tissue damage, aid absorption, and avoid discomfort.
Order these routes from least quickly to absorb medication to most quickly: IV, Oral, Sub Q, IM
Oral, Sub Q, IM, IV
The ventrogluteal site is the preferred site for IM Injections because…
Contains no large nerves or blood vessels
Provides the greatest thickness of gluteal muscle
Contains less fat than the buttock area
Why is the deltoid site not often used for IM Injections?
Why is it still used for IM Injections though?
Because it’s a small muscle.
It quickly absorbs medicine.
What is the appropriate size needle that should be used for an average adult through subcutaneous injection? How long should these needles be?
#24-#26 gauge 3/8 - 5/8 inch
