Step-by-step explanation:
The PRIMARY consideration in selecting an appropriate anesthetic agent is the patient's medical history. This is because a patient's medical history provides vital information on any pre-existing conditions that may influence the choice of anesthetic, risks of adverse reactions, and the patient's overall ability to tolerate the procedure. Before the induction of anesthesia, it is essential that team members, including the nurse and an anesthesia professional, perform a thorough review and oral confirmation of key concerns for the patient's recovery and care.
