Final answer:
The fluoroscopic exposure switch should be the foot-operated type.
Step-by-step explanation:
The fluoroscopic exposure switch should be the foot-operated type. This type of switch is commonly used in healthcare settings, particularly in radiology departments. It allows the healthcare professional to have their hands free to manipulate the equipment during a procedure.
