Final answer:
To prevent the patient from falling from the stretcher, the CNA should place a safety belt or strap around the patient, unlock the wheels of the stretcher, and move the bed to the low position before transferring the patient to the stretcher.
Step-by-step explanation:
To prevent the patient from falling from the stretcher, the CNA should place a safety belt or strap around the patient while using the stretcher. This will provide an additional level of support and security for the patient during the transfer and transportation process. Additionally, the CNA should unlock the wheels of the stretcher while transferring the patient from the bed to the stretcher, as this will help ensure stability and prevent any accidental movement of the stretcher while the transfer is taking place. Moving the bed to the low position before transferring the patient to the stretcher is also important, as it reduces the risk of the patient falling from a height during the transfer process.
