    Given the number of post-discharge patients being monitored, determine the minimum size of the data storage block needed to accommodate all patients, where storage blocks must be sized in powers of 2 to maintain efficient risk assessment grouping. The solution should ensure no patient records are split across blocks while minimizing unused storage space.
