2. A General Hospital consists of a number of specialized wards (Such as Maternity,
Pediatric, and Oncology etc.). Each ward hosts a number of patients, who were
admitted on the recommendation by their own specialist doctor and confirmed
by a Senior Consultant employed by the Hospital. On admission, the personal
