Pain of 8, Refusing the Opioid, Not Walking: Whole-Person Pain Care After Knee Replacement
Post-op day 2 after total knee arthroplasty, a 67-year-old woman rates pain 8/10 at rest and 10/10 with movement. She is taking only scheduled acetaminophen and refuses oxycodone, saying, "My brother got addicted. I'm not going down that road." She has not ambulated since surgery. She slept about three hours, is tearful, and says, "I can't do this, I'm going to be in a wheelchair," then a minute later, "If I don't walk I'll get a clot, right?" Vitals: BP 158/88, HR 96, RR 22, SpO2 96%. Physical therapy is scheduled in 90 minutes and the surgeon's order set permits oxycodone 5 mg every 4 hours as needed.
1. What additional assessment would change your plan - beyond the 0–10 number?

A pain score of 8 is a starting coordinate, not a plan. The elements most likely to change what I do:
- Meaning and history of opioids: what happened with her brother (diversion? overdose? chronic pain?) and whether she has ever taken one herself. Her fear is rational in her frame, and it is treatable with information, not argument.
- Pain pattern and function: rest vs movement, quality, timing relative to the last acetaminophen dose, and what function she is losing because of it. I care whether she can dorsiflex and bear weight, not only whether the number falls.
- Catastrophizing and anxiety: "I'll be in a wheelchair" alternating with "I'll get a clot" is a fear spiral that amplifies pain. A two-item catastrophizing screen or simply asking what she is most afraid of will guide whether the first intervention is analgesic or cognitive.
- Sleep, nausea, constipation, pruritus - modifiable contributors and also barriers she may be weighing against the pill.
- Home context: who is with her, stairs, whether discharge in 24 hours is realistic.
- Her goal, in her words: "Walk to the bathroom by myself" is a better outcome statement than a number.
This assessment deliberately separates the sensory, emotional, and functional strands so the intervention can be matched to the dominant strand.
2. State a whole-person outcome and then sequence your interventions, including how to address her addiction fear.

Outcome (measurable, patient-owned): by the end of postoperative day 3, she will ambulate 30 feet with a walker with pain ≤4/10 during activity, and will report she is able to cope with the pain. Note it includes function and self-efficacy, not just a number.
Sequence:
- Address the fear first, with numbers and a question. Appropriate short-term opioid use in an opioid-naive patient carries a low risk of iatrogenic dependence - far lower than the public narrative suggests - and her brother's situation likely involves different factors (chronic use, dose, duration, other substances). Ask: "What would make you willing to try a small dose for one walk?" Offer a time-limited trial rather than a commitment: one 5 mg dose 30 minutes before PT, with a defined check-in afterward. Preserving her choice is what makes the trial acceptable.
- Optimize the non-opioid base: confirm scheduled acetaminophen is not overdue and that an NSAID is not contraindicated; timing to peak before therapy costs nothing.
- Match non-pharmacologic methods to the actual problem: diaphragmatic breathing or guided imagery before the walk for the anxiety spiral; cold therapy, elevation, and repositioning after; distraction is not a substitute for analgesia when movement pain is 10/10.
- Protect sleep: cluster nighttime checks, premedicate before sleep rather than after waking at 3 a.m.
- Reframe the catastrophizing with one sentence of evidence: early mobility is the single best clot and complication prevention - which she already knows and said.
- Premedicate 30 minutes before PT and attend the first walk so success is engineered rather than hoped for.
3. How do you evaluate whether this is working, and what would make you change course?
Read the worked answer
Evaluate on three axes at once, because they can dissociate:
- Function: did she walk 30 feet? How far on the next attempt? Function is the outcome she cares about and the one least vulnerable to score-reporting bias.
- Experience: activity pain ≤4, and her own coping statement. A patient who reports 7/10 but walks the hall and says "I can do this" is in a different place than one who reports 7/10 and refuses to stand - the same number, opposite plans.
- Safety: sedation level, respiratory rate, nausea, constipation, and any sign of confusion. These are what actually limit opioid titration and would make me stop pushing the trial.
Change course if: she completes the trial and still refuses opioids - then pursue multimodal alternatives (nerve block review with the surgeon, scheduled NSAID, ice, positioning) rather than re-arguing. Change course if pain remains 10/10 with movement and she stops participating - that suggests the dose or route is inadequate or the anxiety component is dominant and undertreated. Change course if sedation rises without analgesia - that argues against escalating.
Document the outcome and the plan in functional language: "Ambulated 30 ft with walker, pain 5/10 during, 3/10 after; 5 mg oxycodone before PT; states 'I think I can do the next one.'" That record gives the next nurse a plan, not just a score.
