(242 cards)
Continuous IV Infusion
Large volume IV infusion given at a set rate over time.
Intermittent IV / Piggyback
Medication given for a short period at scheduled intervals (e.g., every 8 hours).
IV Bolus / IV Push
Small amount of medication injected directly into an IV line over a few minutes.
Isotonic IV Solutions
Same osmolality as body fluids.
Used to treat hypovolemia.
Isotonic IV Solutions Example
0.9% NaCl (Normal Saline),
Lactated Ringer’s (LR)
Hypotonic IV Solutions
Osmolality is less than body fluids.
Used to hydrate cells.
0.45% NaCl (½ Normal Saline)
A hypotonic solution.
Used as a basic maintenance fluid.
0.33% NaCl (⅓ Normal Saline)
A hypotonic solution.
Used to treat hypernatremia.
Hypertonic IV Solutions
Pulls fluid out of cells into the bloodstream.
Examples of Hypertonic Solutions
D5NS: 5% dextrose in 0.9% NaCl
D5LR: 5% dextrose in Lactated Ringer’s solution
What are examples of short-term IV access devices?
Peripheral IV
Non-Tunneled Central Line
Used until no longer needed, if complications occur, or based on hospital guidelines.
How long does a peripheral IV typically remain in place
96 hours to 7 days
What is the usual duration for a non-tunneled central line?
a few days to 2 weeks
Which IV access device is used for medium-term therapy, and how long does it last?
4 weeks to 1 year
What IV devices are used for extended-term therapy, and how long can they last?
Mediports and Tunneled Central Catheters – Can last months to years.
What happens to the needle size as the gauge number increases?
The larger the gauge number, the smaller the needle.
What gauge needle is required for blood products and certain tests or surgeries?
18 gauge (green)
What are the IV catheter color codes for different gauge sizes?
24g – Yellow
22g – Blue
20g – Pink
18g – Green
16g – Gray
What gauge sizes are commonly used for most adult infusions?
18 – 22 gauge
What gauge sizes are used for geriatric and neonatal patients?
22 – 24 gauge
What gauge sizes are used for blood transfusions and procedures?
18 – 20 gauge
What is IV infiltration?
Infiltration occurs when IV fluid leaks into the subcutaneous tissue because the catheter has been displaced from the vein.
What are signs and symptoms of infiltration?
Pain/Swelling
Cool/cold skin
No blood return
IV flow is slow or stops
Tissue damage (if severe)
How can you prevent IV infiltration?
Regularly monitor the IV site
Assess the site frequently
Move the patient with care
