📚 Pain Assessment Scales — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Pain is subjective and is whatever the patient says it is, existing whenever the patient says it does. Scales standardize that report so pain can be tracked and treated. The right scale depends on the patient's age, development, and ability to communicate. Use the same scale each time for a given patient to trend accurately.
🔑
Key points
Understand these first
The numeric rating scale (0 = no pain, 10 = worst pain) is the standard for alert adults who can self-report.
Wong-Baker FACES is used for children 3 and older and for adults with language or cognitive barriers.
FLACC (Face, Legs, Activity, Cry, Consolability) is a behavioral scale for infants and nonverbal patients.
CRIES and the Neonatal Infant Pain Scale (NIPS) assess pain in neonates.
PQRST or OLDCARTS frameworks capture a full pain history: provocation, quality, region, severity, and timing.
Self-report is always the most reliable indicator; behavioral and physiologic signs are used only when self-report is impossible.
✅
Nursing priorities
What to do, in order
Choose an age- and ability-appropriate scale and use that same scale at every reassessment.
Assess pain on admission, at rest and on movement, and reassess after every intervention.
Reassess after IV analgesia within 15-30 minutes and after oral analgesia within 60 minutes.
Believe and document the patient's self-reported number without judgment.
Assess pain as the fifth vital sign alongside the full set of vital signs.
🚩
Red flags — report now
Escalate immediately
Never assume a calm or sleeping patient has no pain; some patients mask pain or withdraw.
Report new, sudden, or sharply escalating pain, as it may signal a complication, not just undertreatment.
Do not delay or withhold ordered analgesia because vital signs appear normal despite a high pain score.
🗣️
Patient teaching
What patients must know
Explain that 0 means no pain and 10 means the worst pain imaginable, and ask the patient to pick a number.
Tell the patient to report pain early rather than waiting until it is severe.
Encourage the patient to describe pain quality, location, and what makes it better or worse.
