2.Jane, the head nurse on the surgery recovery floor, is going to place a request for a system that will create a report from data already in the patient record system and print this report to printers located just outside each of 12 patient's rooms and the central nurses station. Jane feels that a graphical report that combines the patient record of pain and pain medication received is absolutely necessary for the doctors and nursing staff to make proper medical decisions concerning patient recovery. Nurses already record the date, time, and severity of pain each time the patient complains or notifies them of discomfort. The pharmacy nurse records the amount of pain medication administered to each patient immediately after administration. Jane feels that combining these two pieces of information will improve medical decision making and provide better care to the patient. In addition, this method will increase the accuracy of reporting and reduce cost. Assist Jane by completing a System Request.
