When Transferring a Patient from a Bed to a Wheeled

When transferring a patient from a bed to a wheeled stretcher, an EMT uses proper body mechanics when he or she:

A) primarily uses the muscles of his back to move the patient.
B) aligns his shoulder, hips, and feet when moving the patient.
C) transfers the patient to the stretcher all at once, not in stages.
D) keeps his arms locked and the patient away from his body during the transfer.
