The Emergency Room at a Hospital Estimates the Following Requirements

question 96

Essay

The emergency room at a hospital estimates the following requirements for registered nurses (RNs) for the late night shift each week. Nurses work four consecutive days, then have off three days.
$$\begin{array} { | c | c | c | c | c | c | c | } \hline \text { Sunday } & \text { Monday } & \text { Tuesday } & \text { Wednesday } & \text { Thursday } & \text { Friday } & \text { Saturday } \\\hline 3 & 4 & 2 & 2 & 3 & 6 & 4 \\\hline\end{array}$$ Perform cyclical scheduling on the data. (Note that you must identify three-day patterns of minimum requirements). How many RNs are required? How much extra capacity is required?
