Final answer:
Deep cephalic veins are not typically avoided for venipuncture like hematomas, sclerosed veins, or areas with tattoos; hence, they are the correct answer to the question.
Step-by-step explanation:
Areas that should be avoided for venipuncture typically include places where complications could occur, such as hematomas, areas with potential sclerosed veins, and sites that have been altered such as where tattoos are located, due to the potential for difficulties in puncture and risks, including infection. However, when considering deep veins like the deep cephalic veins, although they may not be the primary or first choice for venipuncture due to depth or patient discomfort, they are not generally contraindicated or deemed an area to always avoid like the others listed. Therefore, the correct answer here is 'b. deep cephalic veins'.
