The preinduction physical examination given by the US Army involves the following seven activities. These activities can be performed in any order, with two exceptions: the medical history must be taken first and the exit medical evaluation is the final step. At present there are three paramedics and two physicians on duty during each shift. The maximum number of people can work together in one workstation is two. Only a physician can perform the exit evaluation or conduct the psychological interview. Other activities can be carried out by either physicians or paramedics.
