Question 4

Admin sets

Answer 4

-basic set
-add-a-line set (2 Y sites)
-volume control set
-ADD-vantage system
-MACROdrip
-MICROdrip

Question 5

volume control set

Answer 5

-more precise for concentration
-similar to IV bag just better control

Question 6

Media fill

Answer 6

-ampule to vial to IV bag to patient

Question 7

ADD-Vantage bag

Answer 7

-vial and bag have rubber seal
-connect them and they will mix and stay sterile
-minimal risk of contamination and saves time
-too expensive tho

Question 8

MACROdrip

Answer 8

-default
-large quantities
-faster

Question 9

MICROdrip

Answer 9

-small amts
-60gtt/mL
-used in pediatrics
-patients who needs small or closely regulated amts of IV solution
-better control

Question 10

Drop conversion factor (Drop number)

Answer 10

-tells how many drops per mL
-not accurate but good estimate

Question 11

Poiseuille’s Law

Answer 11

rate=driving force/resistance

Question 12

components of resistance to flow (dec rate)

Answer 12

-tubing (macrobore vs microbore)
-in-line filter
-viscosity of IV fluid
-length of tubing
-venous backpressure

Question 13

Volume fill

Answer 13

if liquid more viscous

Question 14

actual drop number depends on

Answer 14

-viscosity
-surface tension
-density

Question 15

butterfly needle

Answer 15

-harness around needle to prevent injury from movement
-peripheral access

Question 16

over-the needle catheter

Answer 16

-metal pierces vein
