Lab 3: IV Insertion Flashcards
1
Q
what techniques can be used to improve the visibility of the vein & increase the likelihood of a successful puncture
A
- tourniquet
- use of gravity
- pt open and clench their fist a few times
- light tapping/rubbing of the vessel
- heat application
2
Q
how does a tourniquet cause vein enhancement
A
- traps blood in the extremity = vein dilates
3
Q
what is a helpful tip regarding using a tourniquet (3)
A
- if having difficulty, use a double tourniquet
- or manual BP inflated to just below the pts diastolic pressure & maintained at that pressure until insertion complete
- or move tourniquet closer to insertion site
4
Q
how far above should the tourniquet be to the insertion site of a PIV
A
- at least 6”
5
Q
how can you use gravity to cause vein enhancement
A
- lower the extremity below the lvl of the heart to promote venous pooling
6
Q
how does light tapping/rubbing of the vein promote vein enhancement
A
- gentle rubbing w an antiseptic swab will cause blood to fill & dilate the vein
7
Q
what options are available to use heat to promote vein enhancement
A
- dry and moist heat
8
Q
what care must be taken when using heat to promote vein enhancement
A
- avoid excessive temperature that can burn the extremity
9
Q
describe how to use heat to promote vein enhancement
A
- apply for approx 2-5 min (longer if necessary but no longer than 15 mn)
- reassess often (esp with older adults)
10
Q
what is the preferred method for dry heat
A
- warm blanket
11
Q
what is the preferred method for moist heat
A
- wash cloth dampened w warm water, placed on limb, and covered w a towel
12
Q
what are factors that can affect vein enhancement
A
- bp (high or low)
- cold
- shock
- sclerotic veins
- dehydration
- anxiety/apprehension
- tourniquet application too tight or lose
13
Q
what impact does cold and shock have on vein enhancement
A
- causes vasoconstriction
14
Q
what impact do sclerotic veins have on vein enhancement
A
= loss of elasticity
15
Q
what impact does dehydration have on vein enhancement
A
= flattened veins
16
Q
what impact does anxiety/aprehension have on veins
A
= vasoconstriction
17

A
- only when clinically indicated
18
Q
what are clinical indications for change of peripheral IV (10)
A
- pain
- redness
- multiple downstream occlusion alarms w no visible cause
- whenever there is suspicion of contamination
- swelling
- inability to flush and/or infuse w ease
- induration
- sclerosing of vessel
- discharge

19
Q
what should you avoid when picking PIV site selection (8)
A
- areas of flexion and extension
- areas of skin breakdown, disease, bruising, and inflammation
- scleoritc veins
- highly visual veins (tend to roll)
- veins damaged by previous use (phlebitis, infiltration)
- knotted or tortuous veins
- arm with an AV firstula
- veins in an extremity that is edematous, compromised, or injured
20
Q
what is the first choice for PIV site selection
A
- dorsal and ventral forearm
21
Q
why is the forearm the first choice for PIV site selection
A
- veins are longer & straighter
- ulna and radial bones provide natural splinting = permit pt freedome of arm movement and ability to participate in ADLs
22
Q
how far above the wrist should forearm PIVs be and why?
A
- 2-3 finger breadths
- to avoid nerve injury
23
Q
what should you assess first prior to IV placement

24
Q
what is the second choice for PIV site selection
A
- dorsal portion of hand
25
what should you avoid in a PIV of the dorsal portion of hand
- the thumb
26
what is the 3rd choice for PIV site selection
- antecubital area
27
what is imp for placement of a PIV in the antecubital area
- try for 2 fingers width below or above
28
why are antecubital veins last choice for PIV site election
- located at multiple points of flexion and extension = increased risk of phlebitis
29
infusion into the dorsal portion of hand and antecubital area are difficult bc..? what is imp to note w these sites?
- makes hourly assessments difficult (bc often covered by clothing)
- imp to remove asap, to prevent further damage to the vessel
