Q

how big of a syringe would you use if you were going to assess the patency of a PVAD and why

A

always use a 10 mL syringe or bigger since a smaller syringe creates more pressure and can rupture the catheter

Q

how often should you change IV tubing when a pt is receiving an intermittent or secondary infusion

A

change every 24 hours

25
Q

What information do you include when labeling IV tubing

A

Date
time (could be time you changed it or when it should be changed next)
initials

26
Q

how often should you change an IV bag that is continuous IV solution that does not contain medication

A

every 96 hours

26
Q

how often should you change an IV bag that has an intermittent IV solution not containing medication

A

every 24 hours

27
Q

how often should you change an IV bag that has IV solution containing medication

A

every 24 hours

28
Q

where must you document the infusion rate for a PT

A

on the in/out record

29
Q

if you need to temporarily disconnect an IV and cap the end can you use a cap from another piece of equipment

A

yes you can as long as it is not contaminated

30
Q

what is osmolality

A

is the concentration of solutes in a solution

31
Q

what is tonicity

A

the capability of a solution to modify the volume of cells by altering their water content

32
Q

what is normal body fluid osmolality with units

A

285-295 mOsM/L

33
Q

what tonicity is 0.9% NaCl to body fluids

A

it is isotonic to body fluids

34
Q

what tonicity is Lactated ringers to the body

A

acts isotonic to the body

35
Q

what tonicity is dextrose 5% in 0.9% NaCl solution to the body

A

acts isotonic in the body after the dextrose is metabolized

36
Q

what tonicity is dextrose 5% in lactated ringers to the body

A

acts isotonic in the body once the dextrose is metabolized

37
Q

do Isotonic solutions change the volume of cells

A

no they do not since it has the same osmolality as the fluid inside the cells so the fluid stays inside

38
Q

What are three indications for isotonic solutions

A

fluid and sodium loss
hypovolemic shock
mild hyponatremia

39
Q

what tonicity is 0.45% nacl to the body

A

acts hypotonic to the body

40
Q

what tonicity is dextrose 5% to the body

A

acts hypotonic to the body after glucose metabolizes

41
Q

where would the fluid shift if a hypotonic solution was infused intravenously

A

fluid would shift into the cells since they have a higher osmolality than the fluid being infused

42
Q

what conditions would be a contraindication for hypotonic solutions *think anything where you don’t want the cells to swell up

A

Increased ICP
liver disease
trauma or burns

43
Q

if a hypertonic fluid was infused into the body where would the fluid shift

A

fluid would shift out of the cells and into the intravascular space

44
Q

what tonicity is 3% NaCl to the body

A

acts hypertonic to the body

45
Q

what tonicity is total parenteral nutrition to the body

A

it acts hypertonic to the body

46
Q

What are some indications of hypertonic IV fluids
*think anything where you would want volume in the intravascular space and out of the intracellular

A

hypovolemia
hyponatremia
cerebral edema
critical hypoglycemia

47
Q

why are colloid solutions always hypertonic

A

because they contain proteins like albumin that are to big to pass through cell membranes

48
Q

if a pt was infused with a colloid solution where would the fluid shift

A

would shift into the intravascular space since it is HYPERtonic

49
Q

what is the formula for infusion rate gtt/min

A

(IV rate mL/min) x (drop factor gtt/mL)

50
Q

daily input should be equal to daily output plus how many mL? and why

A

plus 500 ml to account for insensible loss of fluid

51
Q

what kind of food would you document on an in and out chart as fluid intake

A

foods that at room temp become liquid

52
Q

would you chart catheter or tube irrigants on an in and out sheet

A

Yes

53
Q

What color is a 24G IV catheter

A

yellow

54
Q

What color is a 22G IV catheter

A

blue

55
Q

What color is a 20G
IV catheter

A

Pink

56
Q

What color is a 18G IV catheter

A

Green

57
Q

What color is a 16G IV catheter

A

purple

58
Q

What color is a 14G catheter

A

Red
