Let's assume that there were no patients admitted or discharged between 12:01 a.m. and 1 a.m. on both days.
Let x
Let y
Therefore, the number of patients in the PCU at 1 a.m. on September 1 would be 20 - x 30 + y
Since the number of patients admitted and discharged should result in the change from 20 patients to 30 patients, we can set up the following equation:
20 - x + y = 30
y = x + 10
This means that the number of patients admitted on September 2 is equal to the number of patients discharged on September 1 plus 10. Therefore, the counts could have been different if the PCU had taken a census at 12:01 a.m. on both days, since the number of patients admitted and discharged during that one-hour period could have varied, resulting in different counts at 1 a.m. on both days.
