A phlebotomist can draw blood from ankle veins with a physician's order because this practice generally requires professional oversight due to the potential complications and risks associated with puncturing deeper veins near the ankle. Typically, the arm veins are preferred for venipuncture due to their accessibility, larger size, and reduced risk of complications. However, there are instances when accessing ankle veins might be necessary, particularly in patients where arm veins are difficult to assess or have been exhausted due to frequent venipunctures.

In such cases, a physician's order ensures that the decision to utilize less conventional sites, like ankle veins, is clinically justified and that the phlebotomist has the correct direction to proceed with the procedure. This protocol establishes an additional level of safety and validation in the care provided to the patient.

Other factors like patient preference, emergency situations, or the condition of arm veins might influence the decision to draw blood, but medical protocols typically prioritize physician guidance to mitigate risks associated with such procedures.
