An older-adult patient is using a wheelchair to attend a physical therapy session. Which action by the nurse indicates safe transport of the patient?

The correct answer is B because backing the wheelchair into the elevator allows the nurse to maintain visual contact with the patient and ensures a safe exit from the elevator. This also prevents any potential accidents or injuries that may occur if the wheelchair is pushed forward into the elevator, where the nurse may not be able to see obstacles or other individuals. Positioning the patient's buttocks close to the front of the wheelchair seat (choice A) may cause discomfort and pressure ulcers. Leading with large rear wheels first (choice C) can be dangerous as it may cause the wheelchair to tip over. Placing a locked wheelchair on the same side of the bed as the patient's weaker side (choice D) restricts the patient's ability to access the wheelchair. Unlocking the wheelchair for easy maneuverability (choice E) is important but not directly related to safe transport in this context.
