Final answer:
A bed cradle is used to keep the covers from resting on a resident's legs and feet, which is different from a hand roll, trochanter roll, or draw sheet that serves other purposes.
Step-by-step explanation:
A device that keeps the covers from resting on a resident's legs and feet is known as a bed cradle. This structure is placed on a bed to prevent sheets and blankets from making contact with the patient's body, which can be especially important for those with certain medical conditions that cause skin sensitivity, or when it's crucial to avoid pressure on a specific area of the body. Unlike a hand roll or trochanter roll, which are used to maintain hand or hip positioning, or a draw sheet used to help reposition a patient, a bed cradle is designed expressly to create a protected space for the legs and feet.
