  1. What are 9 arterial flow to the arm?
    • Aorta
    • brachiocephalic trunk
    • subclavian
    • axillary
    • brachial (1 in. below antecubital fossa)
    • Radial
    • ulnar
    • superficial
    • Palmar
  2. Where is the brachial artery and what does this mean?
    • Just beneath the median basilic vein in antecubital fossa. (medial to midline).
    • Medial antecubital fossa =last choice.
  3. Which veins do we want to aim for?
    a. Deep veins
    b. Superficial veins
    b. Superficial veins
  4. List veins from dorsal/palmar digital veins to axillary veins.
    • Dorsal/palmar digital v.
    • intercapitular v.
    • dorsal venous network (back of hand)
    • 1. cephalic v.(radial side)
    • 2. basilic v.(ulnar side)
    • axillary v.
  5. Which veins can be visible from the antecubital fossa (l-->m)
    • cephalic v.
    • median cephalic v.
    • median v.
    • median basilic v.
    • basilic v.
  6. 2 advantages of placeing IV in dorsom of hand.
    • 1. rare to find arteries here
    • 2. superficial with easy access
  7. 4 disadvantages to placing IV in dorsum of hand.
    • 1. veins smaller in size
    • 2. veins tend to be mobile
    • 3. phlebitis more common
    • 4. more painful
  8. 5 recommended sites for venipuncture.
    • 1.Dorsum of hand
    • 2. Lateral antecubital fossa
    • 3. Ventral forearm
    • 4. Dorsal wrist
    • 5. Medial antecubital fossa
  9. How do you select a venipuncture site?
    • 1. Select one that is straight/visible/unused.
    • 2. Use larger veins for irritating drugs (valium).
    • 3. If long period of time NOT in joint area
    • 4. Infant/children/obese are challenging
  10. 3 Advantages of antecubital fossa?
    • 1. Veins larger than other parts of arm
    • 2. Veins not as mobile
    • 3. Lateral aspect is anatomically safe
  11. 3 disadvantages of antecubital fossa.
    • 1. v. may not be as superficial
    • 2. Medial aspect has avoidable anatomy
    • 3. must immobilize if left in place
  12. what 5 avoidable anat in medial side?
    • 1. Central biceps tendon
    • 2. bipipital aponerosis
    • 3. median cutaneous nerve
    • 4.median nerve
    • 5. brachial artery
  13. Adv and disadv of forearm.
    • A.
    • larger than wrist and hand
    • less mobile
    • no nerves close to venipuncture site
    • D.
    • veins may not be as superficial
  14. about forearm
    • 1. basilic and cephalic vein accessible
    • 2. median vein runs midline of ventral arm
  15. about wrist
    • 1. Ventral NOT GOOD PLACE - small/mobile
    • 2. Radial wrist--> "intern's vein"
    • 3. dorsal/ulnar wrist-->superficial but mobile
    • immobilize if long time
