Final answer:
Arlene can expect coverage for medical expenses, lost wages, and rehabilitation services under workers' compensation, but not for pain and suffering.
Step-by-step explanation:
Under workers' compensation, Arlene can expect various types of benefits due to the injury she sustained during an armed robbery at the bank where she works. These benefits, which are part of workman's compensation insurance, include Coverage for medical expenses related to the injury, Compensation for lost wages during her hospitalization, and Rehabilitation services if they are necessary for her recovery. However, Arlene should not expect to receive compensation for pain and suffering, as workman's compensation insurance typically does not cover this aspect of an injury.
