Lymph node dissection impairs lymph drainage indefinitely, so the affected side is avoided because of infection and lymphedema risk, and there is no automatic time limit that makes it safe. With the only other arm carrying an IV, the correct step is to obtain provider direction rather than choose unilaterally. Drawing above an IV dilutes the sample, and a fingerstick on the affected side carries the same restriction as a venipuncture.
