When the nurse discontinues a 24-hour postoperative client's patient-controlled analgesia (PCA) pump, the client asks to go to the hospital's smoking area to smoke a cigarette. Which response should the nurse provide?

"Your PCA pump has just been discontinued, and you need to wait at least one hour before leaving the unit."

"You may smoke in your room if you keep the door closed and open a window."

"Smoking is hazardous to your health, and since you just had surgery, it would be best for you to avoid smoking."

"As long as you go to the smoking area in a wheelchair, it will be all right for you to go smoke."
