Final answer:
Documentation of a chaperone's presence is required in the GU exam when a male physician performs a female pelvic exam to maintain ethical standards and patient comfort.
Step-by-step explanation:
The phrase that must be documented in the Genitourinary (GU) exam for every female pelvic exam performed by a male physician is an acknowledgement of a chaperone's presence. This is to ensure patient comfort and to maintain ethical standards and professionalism during the examination. It is essential to record that a third party, usually a female nurse or medical assistant, was present throughout the procedure, which includes the Pap smear where tissue is collected from the cervix for cytological analysis.
