Final answer:
The bottom sheet is always part of a daily linen change in hospitals to maintain hygiene standards.
Step-by-step explanation:
In hospitals, the bottom sheet is always part of a daily linen change. The bottom sheet is a fitted sheet that covers the mattress and provides a barrier between the mattress and the patient. It is essential for maintaining cleanliness and preventing the spread of infections.
While the mattress pad, blanket, and bedspread may also be changed regularly, the bottom sheet is typically the part that is changed daily in order to maintain hygiene standards.
