Final answer:
The most appropriate statement by the nurse would be option (b) - You should expect the catheter to be removed within the next 24 hours.
Step-by-step explanation:
The most appropriate statement by the nurse in this situation would be option (b) - You should expect the catheter to be removed within the next 24 hours. This is because after an abdominal hysterectomy, it is common for the urinary catheter to be removed within 24 hours, as long as there are no complications and the client's urine output is stable. Walking to the bathroom without assistance is not a criteria for catheter removal. Bowel function is not directly related to catheter removal. Discussing catheter removal with the surgeon during the next visit is not necessary as it is a routine procedure.
