What pain assessment tools should nurses use in a pain management care plan?

The choice of pain assessment tool depends on the patient population. For adults who can self-report, the Numeric Rating Scale (NRS, 0-10) is the most commonly used. The Visual Analog Scale (VAS) is a 10 cm line for precise measurement. The Wong-Baker FACES scale is used for children ages 3+ and adults with communication barriers. For non-verbal or cognitively impaired patients, behavioral tools include the FLACC scale (for infants and young children), the PAINAD scale (for patients with advanced dementia), and the CPOT or BPS (for intubated ICU patients). The PQRST mnemonic (Provokes/Palliates, Quality, Region/Radiates, Severity, Timing) provides a comprehensive pain history framework.

What is multimodal analgesia and why is it important in nursing care plans?

Multimodal analgesia is the use of two or more analgesic agents or techniques that act by different mechanisms to provide superior pain relief with fewer side effects than any single agent. A typical multimodal regimen includes scheduled acetaminophen (1g q6-8h), a scheduled NSAID or COX-2 inhibitor (if not contraindicated), a neuropathic agent if applicable (gabapentin, pregabalin), regional anesthesia or nerve blocks when appropriate, and opioids reserved for breakthrough pain at the lowest effective dose. Non-pharmacological methods (ice, heat, positioning, distraction, relaxation techniques) complement pharmacological approaches. This approach reduces opioid consumption by 30-50%, decreases opioid-related side effects (respiratory depression, nausea, constipation, sedation), and improves pain scores.

How should nurses monitor for opioid-induced respiratory depression?

Opioid-induced respiratory depression (OIRD) is a life-threatening adverse effect. Nurses should monitor sedation level using the Pasero Opioid-Induced Sedation Scale (POSS) before each opioid dose: S = Sleep/easy to arouse, 1 = Awake and alert, 2 = Slightly drowsy, 3 = Frequently drowsy (arousable, drifts off during conversation), 4 = Somnolent (minimal or no response to stimulation). A score of 3 requires dose reduction and increased monitoring, and a score of 4 requires holding the opioid, stimulating the patient, and considering naloxone. Monitor respiratory rate (concerning if below 10/min), SpO2 (continuous pulse oximetry for high-risk patients), and end-tidal CO2 if available (capnography is the earliest detector of respiratory depression). Risk factors for OIRD include opioid-naive status, obesity, sleep apnea, renal or hepatic impairment, concurrent sedating medications, and age over 65.

Pain Management Nursing Care Plan Example

Pain is the most common reason patients seek medical care, and effective pain management is both a clinical priority and a patient right. Nurses play a central role in pain assessment, intervention, and evaluation. This care plan example covers a patient with both acute post-surgical pain and chronic pain, demonstrating NANDA-I diagnoses, NIC interventions, and NOC outcomes for comprehensive pain management using pharmacological and non-pharmacological approaches.

Condition Overview

Pain is defined by the International Association for the Study of Pain (IASP) as "an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage." Pain is classified as acute (sudden onset, typically related to tissue injury, expected to resolve with healing, usually lasting less than 3-6 months) or chronic (persistent beyond normal healing time, typically lasting more than 3 months, may exist without identifiable tissue damage). Pain can also be classified by mechanism: nociceptive (somatic or visceral, from tissue damage), neuropathic (from nerve damage or dysfunction), and nociplastic (altered pain processing without clear nociceptive or neuropathic cause).

Pain assessment is considered the "fifth vital sign" and should be performed systematically using validated tools. The nursing assessment includes pain intensity (using a standardized scale), quality (sharp, dull, burning, aching, throbbing), location and radiation, temporal characteristics (constant, intermittent, breakthrough), aggravating and alleviating factors, impact on function and quality of life, and the patient's pain goals (what level of pain is acceptable to them). The comprehensive PQRST framework (Provokes/Palliates, Quality, Region/Radiation, Severity, Timing) guides thorough pain assessment.

Typical Patient Presentation

Patients with acute pain typically display observable physiological responses: tachycardia, elevated blood pressure, diaphoresis, dilated pupils, and guarding or splinting of the painful area. They may grimace, vocalize (moaning, crying), exhibit restlessness, or adopt protective postures. However, the absence of these signs does not mean the absence of pain — patients with chronic pain often do not exhibit autonomic responses due to physiological adaptation, and their pain may be just as severe.

Patients with chronic pain may present with depression, anxiety, sleep disturbance, decreased appetite, social withdrawal, functional limitation, and fatigue. They may appear "comfortable" to observers because they have adapted coping mechanisms, leading to a dangerous assumption that their pain is not real or not severe. Pain is always subjective — the patient's self-report is the single most reliable indicator of pain existence and intensity. When patients cannot self-report (cognitive impairment, intubation, infants), behavioral assessment tools must be used.

Sample Assessment Scenario

Patient:Patricia H., 58-year-old female, POD 2 following open cholecystectomy (converted from laparoscopic due to inflammation). PMH: Chronic low back pain for 8 years (lumbar disc disease, failed back surgery syndrome after L4-L5 laminectomy 3 years ago), fibromyalgia, depression, and obesity (BMI 36). Home pain medications: oxycodone 10 mg q8h (chronic), duloxetine 60 mg daily, gabapentin 600 mg TID. She is opioid-tolerant. Current post-operative pain regimen: PCA hydromorphone 0.2 mg q10 min with 4-hour lockout of 4.8 mg, acetaminophen 1g IV q6h, ketorolac 15 mg IV q6h (POD 0-2, transitioning to oral NSAID). She rates her surgical site pain at 7/10 with movement and 4/10 at rest. She also reports her chronic low back pain at its "usual 5/10" and states the hospital bed makes it worse. She is reluctant to ambulate due to both pain sites. She has not slept more than 2 hours at a time since surgery. She reports the PCA "takes the edge off but doesn't really control it." Pain goals: "I'd be happy with a 3 at rest and a 5 with movement — I know I'll never be at zero." Pasero Sedation Scale: 1 (awake and alert). RR 16, SpO2 97%.

NANDA-I Nursing Diagnoses

1. Acute Pain (00132)

Definition: An unpleasant sensory and emotional experience associated with actual or potential tissue damage, with sudden or slow onset of any intensity from mild to severe, with an anticipated or predictable end.

Related factors: Physical injury agent (surgical incision, tissue manipulation during open cholecystectomy, abdominal drain if present).

Evidence:Reports surgical site pain 7/10 with movement, 4/10 at rest. Grimaces and guards abdomen during position changes. Reluctant to ambulate. States PCA "takes the edge off but doesn't really control it." Disrupted sleep.

2. Chronic Pain (00133)

Definition: An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage, with onset more than 3 months ago and persisting.

Related factors: Chronic musculoskeletal condition (lumbar disc disease, failed back surgery syndrome), central sensitization (fibromyalgia).

Evidence:8-year history of chronic low back pain, currently 5/10 (reported as "usual"), worsened by the hospital bed, on chronic opioid therapy (oxycodone 10 mg q8h), fibromyalgia diagnosis, neuropathic pain component managed with gabapentin.

3. Impaired Physical Mobility (00085)

Definition: Limitation in independent, purposeful physical movement.

Related factors: Pain (both acute surgical and chronic back pain), post-operative status, obesity (BMI 36), reluctance to mobilize.

Evidence: Reluctant to ambulate, has not met POD 2 ambulation goals, limited bed mobility due to abdominal and back pain, requires assistance for transfers.

4. Insomnia (00095)

Definition: A sustained disruption in the amount and quality of sleep that impairs functioning.

Related factors: Pain (acute and chronic), anxiety, unfamiliar environment, disruptions from care activities, altered sleep position (cannot sleep in usual position due to surgical pain).

Evidence: Sleeping no more than 2 hours at a time since surgery, reports pain as the primary reason for awakening.

NIC Interventions

For Acute Pain

Pain Management: Acute (1410): Assess pain using the Numeric Rating Scale (0-10) every 4 hours and PRN. Use the PQRST framework for comprehensive assessment every shift. Document pain location, intensity, quality, and impact on function. Evaluate PCA utilization — review demand versus delivery ratio (if the patient is pressing the button frequently without relief, the dose may be inadequate for an opioid-tolerant patient; discuss dose adjustment with the provider). This patient is opioid-tolerant — standard post-operative doses may be insufficient. Coordinate with the acute pain service or anesthesiology. Consider adding a low-dose ketamine infusion if available (effective adjunct for opioid-tolerant patients). Maintain scheduled non-opioid analgesics: acetaminophen 1g q6h and transition ketorolac to oral ibuprofen 400 mg q6h or celecoxib 200 mg BID (assess renal function first). Ensure home gabapentin is continued at the home dose (600 mg TID) — abrupt discontinuation can cause withdrawal and worsen pain. Continue home duloxetine 60 mg daily — it treats both chronic pain and depression.
Analgesic Administration (2210):Assess sedation level using the Pasero Opioid-Induced Sedation Scale (POSS) before each opioid assessment and bolus. Current POSS: 1 (awake and alert) — safe to administer. Monitor respiratory rate (hold and notify if below 10), continuous SpO2 monitoring given opioid-tolerant patient on PCA, and assess bowel function (initiate bowel regimen: docusate 100 mg BID + sennosides 8.6 mg BID). Premedicate 30-45 minutes before physical therapy sessions and ambulation — consider a PCA bolus or PCA nurse-administered bolus before painful activities. Time dressing changes with peak analgesic effect. Plan for PCA transition to oral opioid: calculate total 24-hour PCA consumption, convert to oral equivalent using equianalgesic chart, and consider that this patient's home regimen (oxycodone 30 mg/day) must be maintained as baseline.

For Chronic Pain

Pain Management: Chronic (1415):Acknowledge the patient's chronic pain as real and valid — do not dismiss it or focus solely on the surgical pain. Maintain home chronic pain medications throughout hospitalization (gabapentin, duloxetine, oxycodone). Assess chronic pain separately from acute pain — document both as distinct problems. Address the hospital bed as a modifiable factor: request an egg-crate mattress overlay or alternating pressure mattress, offer additional pillows for lumbar support, and help find the most comfortable position. Discuss realistic pain expectations: the patient's stated goal of 3/10 at rest and 5/10 with movement is reasonable and patient-centered — document this as the target. Avoid judging the patient's opioid use or implying addiction; chronic opioid therapy for chronic pain, when prescribed and monitored, is distinct from substance use disorder.
Complementary Therapy (Non-pharmacological Pain Relief, 1380):Apply heat to the lower back (warm pack, 20 minutes on / 20 minutes off — avoid on the surgical site). Teach deep breathing and progressive muscle relaxation techniques. Offer guided imagery or music therapy as distraction. If available, request a physical therapy evaluation for gentle back exercises and positioning. Consider requesting integrative medicine consultation (massage therapy, acupuncture) if available. Position with a pillow between the knees when side-lying to reduce lumbar strain.

For Impaired Physical Mobility

Exercise Therapy: Ambulation (0221): Premedicate before ambulation (PCA bolus 15-20 minutes prior). Start with dangling at the bedside, then progress to standing and short hallway walks. Set incremental goals: POD 2 goal — ambulate at least 100 feet with assistance twice. Apply an abdominal binder for surgical site support during ambulation if ordered. Use a gait belt. Teach the patient to splint the abdomen with a pillow during position changes. Explain the benefits of early mobilization: reduced ileus risk, DVT prevention, improved respiratory function, faster recovery. Collaborate with PT if mobility goals are not being met.

For Insomnia

Sleep Enhancement (1850):Cluster nighttime care to allow 3-4 hour uninterrupted sleep blocks. Provide earplugs and an eye mask. Optimize pain control before sleep — administer scheduled analgesics timed for overnight coverage. Position comfortably with pillows for support (semi-Fowler's for abdominal comfort, pillow under knees for back pain). Reduce nighttime lighting and noise. Limit caffeine after noon. Maintain a consistent pre-sleep routine. Discuss trazodone or melatonin with the provider if non-pharmacological measures are insufficient (assess for opioid interaction). Set realistic expectations — some sleep disruption is normal in the post-operative period, but improving sleep duration from 2 hours to 4-hour blocks would be a meaningful improvement.

Discharge Planning Considerations

Discharge pain management for this patient requires careful transition planning given her opioid tolerance and dual acute/chronic pain conditions. Key considerations: transition the PCA to oral analgesics (calculate conversion using equianalgesic tables, adding the acute pain requirement to her baseline chronic dose), develop a tapering plan for the acute pain opioid component (typically taper over 1-2 weeks as surgical pain resolves), ensure her home chronic pain regimen is resumed (oxycodone, gabapentin, duloxetine), provide a clear written pain management plan with scheduled and PRN medications, educate on warning signs requiring return to care (fever, wound complications, uncontrolled pain), schedule follow-up with the surgeon at 2 weeks and with her pain management provider within 1-2 weeks, provide constipation prevention instructions for ongoing opioid use, and discuss non-pharmacological strategies she can use at home (heat, gentle stretching, relaxation techniques). Ensure safe storage of opioid medications at home. If the patient has not been connected to a comprehensive pain management program for her chronic pain, this hospitalization is an opportunity to make that referral.

Building Your Own Pain Management Care Plan

Pain management care plans are among the most individualized in nursing, as pain is a subjective experience influenced by tissue damage, nervous system processing, psychological state, cultural background, past experiences, and patient expectations. This example covers a complex case with coexisting acute and chronic pain in an opioid-tolerant patient; a post-operative patient without chronic pain would have a simpler analgesic plan with a focus on multimodal non-opioid strategies and opioid minimization.
