The nurse is caring for a 75-year-old client following repair of a femur fracture five days ago. Since surgery, the client has been experiencing frequent episodes of urinary incontinence. The client states, "I've never had this problem. I don't understand why this is happening now." What is the best response from the nurse?

"When you aren't up and moving your bladder becomes hyperactive, the increased bladder activity can cause urine to overflow."

"When you lay in bed for extended periods, your bladder, which is made of muscle, can lose its tone, resulting in loss of control."

"When you lay in a flat position for too long, pressure builds up in the bladder causing spasms and urine leakage."

"When you don't get enough fluids, your bladder doesn't fill enough causing a loss of muscle tone and control."
