Exam 1 Study Cards Flashcards
The GOAL of IV therapy is?
To correct or prevent fluid and electrolyte disturbances
Allow direct access to vascular system
Can be continuous or intermittent
Require frequent monitoring
Administration of medicines
Administration of blood/blood products
Knowledge to identify and correct problems & discontinue the infusion to maintain patient safety.
Roughly, what percentage of your body is water?
60%
Intracellular fluid makes up roughly 42%
Extracellular makes up 17%
Osmolality-
Is used to describe fluids inside the body
Osmolarity-
Refers to fluids in solutions
Isotonic solutions are used…
To expand blood volume
Isotonic solutions include Normal Saline or 0.9% NaCl as well as Lactated Ringers
Hypotonic solutions are used…
For dehydration
Hypotonic solutions include 0.45% NaCl as well as 0.33% NaCl
Hypertonic solutions are used…
To draw fluid into vascular compartments (not for clients with kidney or heart problems)
Hypertonic solutions include D5 NS, D5 1/2 NS, and D5LR
Intravenous Fluids are delivered directly into the bloodstream via a…
Vein
The fluid rate of a 24 gauge (yellow) needle is…
15-25 ml/min
The fluid rate of a 22 gauge (blue) needle is…
26-36 ml/min
The fluid rate of a 20 gauge (pink) needle is…
50-65 ml/min (maintenance rate)
The fluid rate of a 18 gauge (green) needle is…
85-105 ml/min
The IV bag should be hung how many inches above the patients heart?
36
For adults the typical needle gauge for an IV would be…
20-22 gauge
If an adult was expecting to have a blood transfusion, what gauge needle would be used?

The peripheral IV site located on the top of the hand is called…
Metacarpal
The peripheral IV site located the forearm is…
Basilic & cephalic
A central line or PICC line is inserted…
Into the subclavian or jugular vein
Central lines are typically used when…
The patient needs large amounts of fluids, rapid medication, infusion of highly concentrated solutions, or long term IV therapy
PICC stands for…
Peripherally inserted central catheter
Signs of infiltration due to and IV can include…
Swelling, discomfort, coolness at the infiltration site, sizeable decrease in flow rate
Signs of phlebitis at the IV site can include…
Pain at or near the site, heat, redness, and swelling at the site
What are the drop factors for a macrodrip?
10gtt/mL, 15gtt/mL, and 20gtt/mL
What is the drop factor for a microdrip?
60gtt/mL
Why even after calculation the flow rate for an IV would we check the IV hourly?
Counting drops is not precise. Rates may need to be adjusted to compensate.
If the patient has continuous IV therapy, how frequently should the tubing and site be changed?
The tubing for the IV should be changed every 72 hours
The site should be changed every 48-72 hours
