Memorize the illustration of the vessels of the arm on page 182 (see also below), and then try the exercise on the next page.

ANTECUBITAL VEINS OF THE ARM USED FOR VENIPUNCTURE

  • 1ST CHOICE = MEDIAN CUBITAL VEIN. It is usually the largest, and best anchored. Least painful to puncture. Least likely to bruise.
      
  • 2nd CHOICE = CEPHALIC VEIN. It is usually harder to palpate but is fairly well anchored. Often is the only vein that can be palpated in obese patients.
      
  • 3rd CHOICE = BASILIC VEIN. It is often the easiest to palpate, but it is not anchored. Therefore it will roll and bruise more easily. Venipuncture tends to be more painful to patient. It has the highest possibility of accidental puncture of the median nerve or brachial artery. Puncture of the median nerve or brachial artery leads to possible patient complications and lawsuits.
