(a) "i noticed you use very little pain medication. you must be very brave and strong. but without pain medication, you will get weaker, not stronger."(b) "i noticed you don't use much pain medication. if you don't push that button, i will. you need that medicine. don't worry about getting addicted. it won't happen."(c) "i noticed you haven't used your pain medication as often as you could, even though it is painful for you to get out of bed and to walk. many people are reluctant to take pain medication. tell me what makes you reluctant."(d) "i can understand why you are reluctant to use pain medication. many people feel the same way. yet without pain relief, you can get atelectasis, pneumonia, and blood clots, and maybe even develop an ileus."
