Upon written request, the facility must return a resident's funds in not later than how many calendar days?

The correct answer, which is 15 days, is based on the regulations governing the management of residents' funds in healthcare facilities. According to these regulations, when a resident submits a written request for the return of their funds, the facility is required to process this request and return the funds within a specific timeframe to ensure the residents have access to their personal finances without undue delay.

This timeframe is set at 15 calendar days to strike a balance between allowing the facility sufficient time to verify and process the request while also protecting the rights of the residents to access their own funds. This regulation emphasizes the importance of financial management and transparency in long-term care settings, which is vital for maintaining trust and upholding residents' dignity.

The other options, such as 5 days, 10 days, or 30 days, do not align with the mandated timeframe established by the regulations. These periods may either be too short to allow for necessary processing or too long, which would not be in the best interest of the residents and could impact their autonomy. Hence, the correct timeframe is indeed 15 calendar days.
