Believe the client
The foundational principle of pain management on the NCLEX is that pain is whatever the experiencing person says it is, existing whenever they say it does. This single sentence resolves a large share of pain items, because most distractors are built from disbelief: the client is sleeping so cannot be in pain, the vital signs are normal so pain must be mild, the client was laughing with visitors so the report is exaggerated.
All of those are wrong. Clients with chronic pain frequently have normal vital signs because physiological adaptation occurs. Clients use distraction, humour and sleep as coping mechanisms. The exam consistently rewards the option that accepts the client's report and acts on it.
Assessment should be structured. Use a validated scale appropriate to the client: a numeric rating scale for most adults, the FACES scale for children and clients with communication difficulty, and a behavioural scale such as FLACC for infants or non-verbal clients. Document location, quality, intensity, onset, duration, aggravating and relieving factors, and the effect on function. Then reassess after the intervention within an appropriate interval — roughly thirty minutes for parenteral routes and an hour for oral.
- •Self-report outranks vital signs and appearance
- •Chronic pain often presents with normal vital signs
- •Match the scale to the client's age and communication ability
- •Always reassess after intervening — this step is frequently the correct answer
Opioid safety
Respiratory depression is the effect that kills, and sedation reliably precedes it. That is why sedation scoring alongside respiratory rate is the safest monitoring approach, and why an increasingly drowsy client who is difficult to rouse is more concerning than a specific respiratory rate number in isolation. Naloxone reverses opioid effects, but it also reverses analgesia and has a shorter duration than many opioids, so continued monitoring after administration is essential.
Constipation is the one opioid side effect that does not diminish with tolerance. Anticipate it from the first dose with fluids, fibre where appropriate and a prescribed stimulant laxative. Nausea, pruritus and sedation typically improve over the first days of therapy. Urinary retention is common post-operatively and should be assessed rather than assumed away.
Patient-controlled analgesia items are almost always safety items. The client alone presses the button, because the built-in safety mechanism is that an over-sedated client cannot press it. A family member pressing it defeats that protection entirely and is a reportable safety event requiring immediate teaching. Verify the pump settings with a second nurse, monitor sedation and respiratory rate, and teach the client to dose before pain becomes severe.
| Situation | Wrong approach | Correct nursing action |
|---|---|---|
| Client reports 8/10 pain but vital signs are normal | Question the report | Believe the client and treat the pain |
| Client is sleeping but rated pain 9/10 earlier | Assume pain has resolved | Assess on waking; sleep is a coping mechanism |
| Family presses the PCA button | Allow it to help the client | Stop it immediately and teach the family why |
| Client becomes drowsy on opioids | Continue and observe casually | Assess sedation and respiratory rate; hold and notify if deepening |
| Client on long-term opioids requests more | Suspect drug-seeking | Assess for tolerance and reassess the regimen |
Non-pharmacological methods and special populations
Non-pharmacological approaches are adjuncts, not substitutes, and the exam expects you to combine them. Repositioning, heat and cold, massage, distraction, guided imagery, relaxation breathing, music and transcutaneous electrical nerve stimulation all appear as correct components of a plan. A common trap offers a non-pharmacological measure alone for severe acute pain, which is inadequate.
Older adults are frequently undertreated. They may underreport pain, describe it as discomfort or aching, or fear addiction and being a burden. Cognitive impairment increases the risk further, so use behavioural observation — grimacing, guarding, restlessness, agitation, withdrawal, decreased appetite — as supporting evidence when self-report is unavailable.
In clients with a history of substance use disorder, the exam expects pain to be treated adequately and without moral judgement, often with specialist input. Tolerance means higher doses may be required. Physical dependence and addiction are distinct concepts, and confusing them is the basis for several distractors.
- •Combine pharmacological and non-pharmacological methods
- •Non-drug measures alone are inadequate for severe acute pain
- •Older adults underreport — use behavioural indicators as supporting evidence
- •Tolerance and dependence are not addiction
Practising pain items
Pain appears across adult health, fundamentals, paediatrics, maternity and management of care, so it is worth revising as a cross-cutting theme rather than a chapter. Whenever you meet a pain item in practice, categorise it: is this an assessment item, a safety item, a teaching item or a bias item? Naming the type speeds up elimination.
During rationale review, note every distractor built on disbelief of the client, because recognising that pattern converts a whole family of questions into automatic answers.
Then interleave pain content with pharmacology and prioritisation practice, since opioid safety questions frequently double as respiratory assessment questions and as first-client-to-see questions.
