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.
