If Jane has never had her blood drawn, the phlebotomist should allow her to?

Allowing Jane to sit in an armchair with support is the most appropriate option when drawing blood from someone who has never had this procedure before. This position provides comfort and stability, which can help alleviate anxiety for a patient who may be feeling nervous about their first experience with phlebotomy. A supported sitting position minimizes the risk of fainting or feeling lightheaded, improving both the patient's experience and the success of the blood draw.

Sitting in an armchair allows for easy access to the arm for venipuncture and ensures that Jane can lean back and have her feet flat on the ground, which is essential for maintaining blood flow and reducing discomfort during the procedure. Additionally, waiting for the draw in a comfortable, supportive environment can help ease her apprehension, making it more likely for the process to go smoothly.
