butterfly needle

Answer 3

a small, winged-tip needle used to initiate intravenous access

Question 4

cannula

Answer 4

a tube inserted into a vessel, duct, or cavity

Question 5

catheter hub

Answer 5

the “handle” of an intravenous catheter, the part that allows access to the catheter’s lumen for a variety of functions, such as the injection or infusion of fluids or drugs or the introduction of a guide wire

Question 6

colonization

Answer 6

implantation and growth of a micro-organism on or in a host

Question 7

central venous catheter

Answer 7

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

Question 8

drip chamber

Answer 8

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 9

drip factor or drop factor

Answer 9

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

Question 10

embolus

Answer 10

a blood clot or a bolus of air developed in or introduced into a blood vessel that moves from its place of origin and is capable of obstructing blood circulation

Question 11

flash chamber

Answer 11

the portion of an over-the-needle catheter that allows observation of a blood return when the catheter enters a vein

Question 12

fluid-volume deficit

Answer 12

loss of both water and electrolytes from the extracellular fluid; also called hypovolemia

Question 13

heparin lock

Answer 13

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

Question 14

hypertonic

Answer 14

referring to a solution that has a higher osmolarity than body fluids have

Question 15

hypotonic

Answer 15

referring to a solution that has a lower osmolarity than body fluids have

Question 16

infiltration

Answer 16

seepage or introduction of fluid, such as intravenous fluid, into the tissues surrounding a blood vessel; similar to extravasation

Question 17

infusion

Answer 17

slow, intentional introduction of fluid into a vein

Question 18

infusion pump

Answer 18

device that delivers intravenous fluids via positive pressure at a specific preset rate

Question 19

injection cap

Answer 19

a rubber cap attached to the end of an intervenous catheter or extension tubing to allow access to the blood vessel for injecting fluid

Question 20

injection port

Answer 20

a small, covered, branched portion of intravenous tubing configured as a place to inject medication or fluid into the infusing solution

Question 21

intravascular

Answer 21

within a blood vessel

Question 22

introducer needle

Answer 22

the needle inside an over-the-needle catheter used to pierce the wall of a vein to initiate intravenous access that is withdrawn and discarded after the catheter is properly positioned within the vein

Question 23

isotonic

Answer 23

referring to a solution that has the same osmolarity as body fluids

Question 24

over-the-needle catheter

Answer 24

a plastic catheter that fits over a needle and is used to pierce the wall of a vein to initiate intravenous access

Question 25

patent

Answer 25

open and unobstructed

Question 26

percutaneous

Answer 26

performed through the skin

Question 27

peripherally inserted central catheter (PICC)

Answer 27

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 28

phlebitis

Answer 28

inflammation of a vein

Question 29

roller clamp

Answer 29

device with intravenous 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 30

saline lock

Answer 30

an intravenous catheter inserted into a vein and left in place for the intermittent administration of medication through its port or as an open line for emergency situations and intermittently flushed with normal saline solution to maintain patency

Question 31

thrombosis

Answer 31

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

Question 32

time tape

Answer 32

self-adhesive, coated tape used for labeling an intravenous infusion, for example, with the time it was started

Question 33

transparent dressing

Answer 33

a protective covering often used over intravenous insertion sites to allow easy visualization of the site for signs of inflammation

Question 34

vascular access device (VAD)

Answer 34

an umbrella term that includes a variety of catheters, cannulas, and infusion ports that allow intermittent or continuous access to a blood vessel
