IV therapy

Question 1

isotonic

Answer 1

a solution that has same osmolarity as body fluids

Question 2

hypotonic

Answer 2

solution that has a lower osmolarity than body fluids

Question 3

hypertonic

Answer 3

solution that has a higher osmolarity than body fluids

Question 4

infusion

Answer 4

slow, intentional introduction of fluid into a vein

Question 5

electronic infusion device (EID)

Answer 5

medical device that delivers fluids into a PTs body in a controlled manner

Question 6

drip/drop factor

Answer 6

• min flow rate

- the calibration or number of drops per ml of solution delivered for a particular drip chamber

Question 7

drip chamber

Answer 7

the portion of an intravenous administration set that lies just below the tubing insertion spike and allows visualization of the individual drops of solution being infused; the portion squeezed and released to begin the flow of solution immediately after insertion of the spike into the solution bag or bottle when preparing an intravenous infusion set

Question 8

roller clamp

Answer 8

a device with IV tubing threaded through it that acts as a valve when turned (rolled) to increase, decrease, or stop the flow of fluid through the tubing

Question 9

fluid vol deficit

Answer 9

loss if both water and electrolytes from teh ECF, also called hypovolemia

Question 10

infiltration

Answer 10

seepage or introduction of fluid, ex. IV fluid, into the tissues surrounding a blood vessel; similar to extravasation

Question 11

phlebitis

Answer 11

inflammation of the vein

Question 12

thrombosis

Answer 12

the formation or presence of a stationary blood clot within a blood vessel

Question 13

heparin lock

Answer 13

an IV catheter inserted into a vein and left in place for the intermittent admin of med through its port or as an open line for emergency situations and intermittently flushed with a heparin solution to maintain patency

Question 14

IVPB

Answer 14

medication and a small volume of IV fluid is infused through an existing IV line

Question 15

backprime

Answer 15

• ## backprime the primary fluid up into the secondary tubing to displace the air in that tubing

Question 16

intermittent infusion

Answer 16

infusion of a volume of fluid/medication over a set period of time at prescribed intervals and then stopped until the next dose is required. An intermittent IV medication may be called a piggyback medication, a secondary medication, or a mini bag medication

Question 17

continuous infusion

Answer 17

Sometimes an IV medication or fluid is given continuously, or all the time. But sometimes we may want to administer an IV fluid and/or medication to a patient only at specific times; this is called an intermittent IV infusion.

Question 18

Microdrip tubing

Answer 18

Microdrip tubing universally delivers 60 gtt/mL. It is used for infusing small or very precise amounts of fluids

Question 19

macrodip tubing

Answer 19

his is the standard type of tubing used for general I.V. administration. This type of tubing delivers a certain number of gtt/mL, as specified by the manufacturer. Macrodrip tubing delivers 10, 15 or 20 gtts equal to 1 mL. Macrodrips are large drops; therefore, large amounts of fluid are administered in macrodrops.

Question 20

extravasation

Answer 20

drug leaks outside the vein onto or into the skin, causing a reaction. In chemotherapy, drugs are classified into two broad categories based on the effect they have on tissues when they extravasate - irritants and vesicants.Mar 4, 2016

Question 21

gravity infusion

Answer 21

gravity flow, height of the container influences flow rate

Question 22

hourly rate

Answer 22

IV infusion rate

Question 23

IV bolus

Answer 23

• introducing a concentrated dose of med directly into a systemic circulation
• dose can be restricted, but dangerous, not time for errors
• may cause direct irritation to lining of blood vessels

Question 24

peripherally inserted central catheter (PICC)

Answer 24

a catheter used for long-term intravenous access and inserted in the basilic or cephalic vein just above or below the antecubital space with the tip of the catheter resting in the superior vena cava

Question 25

central venous catheter

Answer 25

a blood-vessel access device usually inserted into the subclavian or jugular vein with the distal tip resting in the superior vena cava just above the right atrium; used for long-term intravenous therapy or parenteral nutrition
