You are the nurse manager on a pediatric unit. For the next fiscal year you will be adding 4 intermediate care beds in addition to the 15 acute-care beds that you already have. Your occupancy level runs close to 90%. You calculate that you will need to add TWO FTE RN positions per 8-hour shift to cover the additional beds. Calculate the number of FTE’s you will need to provide full time coverage for 2 FTE’s per 8-hour shift. Be sure to take in to consideration that you are a 24/7 operation and that your staff will need to take vacation, sick and other time away from work. Each FTE will get paid for the following : Holidays 9 Sick days 7 Vacation days 7 Education days 2 You need to calculate the Net Paid Days for each new FTE to be able to determine the total number of FTE’s needed to provide 24/7 coverage as you add the new beds. Show your calculations. Assume that the cost of a Registered nurse salary is $50,000 and benefits are $15,000. Compute the total annual cost of the additional staff. Show your calculations.
