What are the skin layers? Correct Answer - 1. Epidermis
(uppermost layer, protective cover for dermis)
2. Dermis (capillaries and nerves)
3. Superficial fascia (superficial veins located here)
___________________ technique must be used for IV insertion because

causing __________________. Correct Answer - 1. Aseptic
2. superficial fascia
3. cellulitis
What are the 3 layers of the blood vessels? Correct Answer - 1.
Tunica intima (innermost)
2. Tunica media
3. Tunica adventitia (outermost)
Venous Tone Correct Answer - The property of the venous
system reflecting venous pressure and venous resistance; stimulates
vasoconstriction or vasodilation
Vessel spasms occur with vaso_______________, narrowing to occlude
bloodflow. Correct Answer - constriction
True or False. Arteries can collapse. Correct Answer - FALSE.
Arteries CANNOT collapse, only veins collapse.
,What are some causes of vessel spasms? Correct Answer - 1.
Temperature changes
2. Chemical irritation
3. Mechanical irritation
Vessel spasms are relieved by the application of _______ to the vein,
which results in vaso____________ that improves the flow of blood.
Correct Answer - 1. heat
2.dilation
True or False. Arteries pulsate, veins do not. Correct Answer -
True
Veins
- Carry UNoxygenated blood TO the heart
- HAVE valves
- WILL collapse
- Are located close to the surface
- Do NOT pulsate Correct Answer - Arteries
- Carry Oxygenated blood from the heart to the body
- Do NOT have valves
- Will NOT collapse
- Are located deep in tissue, protected by muscle
- DO pulsate
Aberrant Artery Correct Answer - An artery that is
superficially located in an unusual place
What are some conditions that may make it difficult to cannulate a
vein? Correct Answer - - extra body fat
- extensive burns
- IVDA
, INS Standards: "Select the smallest-gauge peripheral catheter that
will accommodate the prescribed therapy and patient need while
maintaining peripheral vein preservation, using the forearm to
increase dwell time, decrease pain during dwell time, promote self-
care, and prevent accidental removal or occlusions." Correct
Answer - INS Standards: "Steel winged devices are for single
dose administrations and are not to be left in place."
What are the superficial veins of the upper extremities? Correct
Answer - 1. Digital veins
2. Metacarpal veins
3. Cephalic vein
4. Basilic veins
5. Median veins
Which vein location is to be used as a last resort? Correct Answer
- Digital veins
Where is a good place to start an IV at initiation of IV infusion
administration and why? Correct Answer - In the metacarpal
veins (unless contraindicated, as in geriatric adults) because it
enables the nurse to be able to initiate each successive venipuncture
above the previous site.
The Cephalic Vein Correct Answer - - In the RADIAL part of the
dorsal venous network formed by the metacarpal veins
- flows along THUMB side of arm and part of the RADIAL artery runs
under
- excellent route for infusing chemically irritating medications and
blood transfusion
- good for SHORT periods
