A phlebotomist is preparing to collect a blood specimen from a patient who has active Mycobacterium tuberculosis Which of the following precautions should the phlebotomist follow

Chewing gum may serve as a distraction, but it does not address the physiological aspects of needle phobia or the potential for fainting. This action may also complicate the procedure by making it difficult for the patient to remain still, which is essential for a successful blood draw.

While flexing the elbow can help with vein visibility, it does not specifically help alleviate anxiety or discomfort associated with needle phobia. The focus should be on ensuring the patient's comfort and relaxation rather than just positioning the arm.

Warming the site can help with vein dilation and make the blood draw easier, but it does not directly address the psychological component of needle phobia. This action may be beneficial in some contexts but is not the most effective strategy for a patient experiencing significant anxiety.
