b. has a record of such an impairment; or
c. Is regarded as having such an impairment.
In addition, a qualified employee or applicant with a disability is an individual who, with or without reasonable accommodation, can perform the essential functions of the job in question.
Based on your information, this is appears to be a temporary medical condition that is not a permanent disability and right now the person cannot perform the essential functions of the position.
Therefore, the bank has no liability with regard to the ADA to consider this person as a qualified applicant, and subsequently no reasonable accommodation can be made.
Tell the person that whenever they are released from medical care and able to resume normal work activities, they can reapply for the position if it is still available.
