Pain management questions reward one core belief, that the client's self-report is the truth, plus a handful of safety rules. Work through these 10 practice questions on pain assessment, the right scale for each patient, the WHO ladder, opioid safety, and the tolerance-versus-addiction distinctions, each with a full rationale.
Pain Management: Assessment, the WHO Ladder & Opioid Safety
Pain is a subjective experience, and the client's self-report is the single most reliable indicator of pain. The classic teaching is that "pain is whatever the client says it is, existing whenever they say it does." Believe the client even when vital signs and behavior look normal: in chronic pain the body adapts, so a client may report severe pain while smiling, resting, or showing stable vital signs. Absence of grimacing or tachycardia does not mean absence of pain. Match the assessment tool to the population: a numeric 0-10 scale for adults who can self-report, Wong-Baker FACES for young children (about age 3+) or those with verbal difficulty, FLACC for infants and nonverbal children, and PAINAD for clients with advanced dementia. Use OLDCARTS or PQRST to characterize the pain, and reserve behavioral or observational cues for situations where self-report is impossible.
Treatment follows the WHO analgesic ladder: step 1 non-opioids (acetaminophen, NSAIDs) with adjuvants; step 2 adds a mild opioid; step 3 uses strong opioids for moderate-to-severe pain. Adjuvants such as gabapentin, pregabalin, and certain antidepressants target neuropathic pain. Multimodal analgesia combines agents to spare opioids. For constant pain, give scheduled around-the-clock dosing with added breakthrough doses rather than PRN-only. Patient-controlled analgesia is pressed by the client only; "PCA by proxy" is unsafe.
For opioid safety, remember that sedation precedes respiratory depression, so monitor the sedation level and respiratory rate, hold and reassess for oversedation, and use naloxone for overdose. Constipation is an expected effect that does not improve with tolerance, so start a prophylactic bowel regimen. Distinguish tolerance (needing more for the same effect), physical dependence (withdrawal if stopped abruptly, an expected response), addiction (compulsive use despite harm), and pseudoaddiction (drug-seeking from undertreated pain that resolves once pain is controlled). Do not undertreat pain out of unfounded fear of addiction, and add non-drug measures such as heat, cold, positioning, distraction, relaxation, and TENS.
Pain Management NCLEX Practice Questions
Question 1 · Pain Assessment
A nurse is assessing a client with chronic low back pain. The client's blood pressure and heart rate are within normal limits, and the client is calmly watching television, yet rates the pain 8 out of 10. Which finding is the most reliable indicator of this client's pain?
- A The client's own report of the pain
- B The client's heart rate and blood pressure
- C The presence of facial grimacing and guarding
- D The nurse's judgment based on the diagnosis
Show answer & rationale
Correct answer: A
The client's self-report is the single most reliable indicator of pain. The guiding principle is that pain is whatever the client says it is, existing whenever the client says it does. Believing the client's report of 8 out of 10 and treating accordingly is correct. Relying on heart rate and blood pressure is wrong because in chronic pain the autonomic nervous system adapts and vital signs frequently normalize; stable vitals do not rule out significant pain. Judging pain by facial grimacing and guarding is also unreliable: many clients with long-standing pain learn to control their expressions or distract themselves, so the absence of grimacing does not indicate the absence of pain. Using the nurse's judgment based on the diagnosis substitutes the clinician's assumption for the client's experience and leads to undertreatment; two clients with the same diagnosis can report very different pain. Objective and behavioral cues are supplementary and become primary only when a client cannot self-report (for example, infants or clients with advanced dementia). Clinical pearl: think 'self-report first.' A calm, smiling client with normal vital signs who reports severe pain is still in severe pain until proven otherwise. Undertreating because a client 'does not look like they are in pain' is a common and harmful error. Current US standards direct nurses to accept and act on the self-report and to reassess after intervention.
Question 2 · Pain Scale Selection
A nurse needs to assess pain in a 6-month-old infant who is 1 day post-op and unable to self-report. Which pain assessment tool is most appropriate?
- A Numeric 0-to-10 rating scale
- B Wong-Baker FACES scale
- C PAINAD scale
- D FLACC scale
Show answer & rationale
Correct answer: D
The FLACC scale (Face, Legs, Activity, Cry, Consolability) is the correct choice because it is a behavioral, observational tool validated for infants and nonverbal children who cannot self-report. The nurse scores each of the five categories and totals them to estimate pain intensity. The numeric 0-to-10 rating scale is wrong because it requires the cognitive ability to understand and assign a number, which a 6-month-old cannot do. The Wong-Baker FACES scale is designed for children roughly age 3 and older (and others with verbal difficulty) who can point to a face that matches their feeling; a 6-month-old cannot reliably do this either. The PAINAD scale (Pain Assessment in Advanced Dementia) is an observational tool for adults with advanced dementia who cannot self-report, not for infants. Memory aid: match the tool to the population. Numeric scale for adults who can self-report; Wong-Baker FACES for young children about 3+ or verbal difficulty; FLACC for infants and nonverbal children; PAINAD for advanced dementia. Behavioral tools like FLACC and PAINAD are used precisely because self-report is impossible in these populations. Current standards emphasize choosing a developmentally and cognitively appropriate, validated instrument and using it consistently to trend a client's pain and response to treatment.
Question 3 · WHO Analgesic Ladder
A client with diabetes reports burning, tingling, shooting pain in both feet consistent with diabetic peripheral neuropathy. Which medication would the nurse anticipate as most effective for this type of pain?
- A Acetaminophen
- B Ibuprofen
- C Gabapentin
- D Morphine
Show answer & rationale
Correct answer: C
Gabapentin is correct because it is an anticonvulsant used as an adjuvant analgesic that specifically targets neuropathic pain such as diabetic peripheral neuropathy. Neuropathic pain (burning, shooting, tingling) arises from nerve dysfunction and responds poorly to standard analgesics but well to adjuvants like gabapentin, pregabalin, and certain antidepressants (duloxetine, tricyclics). Acetaminophen is wrong because it is a non-opioid effective for mild nociceptive pain and fever but has little effect on neuropathic pain. Ibuprofen, an NSAID, is also primarily effective for inflammatory and nociceptive pain, not nerve pain, and carries GI and renal risks that are a concern in diabetic clients who may have nephropathy. Morphine, a strong opioid, can blunt severe pain but is not first-line for chronic neuropathic pain; opioids are less effective for nerve pain and carry dependence, sedation, and constipation risks, so guidelines favor adjuvants first. On the WHO analgesic ladder, adjuvants can be added at any step, and for neuropathic pain they are the cornerstone. Clinical pearl: when you see the words burning, shooting, tingling, or numb, think neuropathic and think gabapentin or pregabalin, not just opioids. Multimodal therapy that combines an adjuvant with non-drug measures often controls neuropathic pain while sparing opioids.
Question 4 · Opioid Safety
A client using an IV morphine PCA is difficult to arouse, and the respiratory rate has dropped to 8 breaths per minute with shallow effort. Which action should the nurse take first?
- A Encourage the client to press the PCA button for better relief
- B Stop the opioid, stimulate the client, and have naloxone ready
- C Continue routine monitoring and reassess in 1 hour
- D Have a family member press the PCA button while the client rests
Show answer & rationale
Correct answer: B
Stopping the opioid, stimulating the client, and having naloxone ready is correct. Sedation usually precedes opioid-induced respiratory depression, so an increasingly sedated client with a respiratory rate of 8 and shallow breathing is showing signs of opioid toxicity that require immediate action. The nurse stops further opioid delivery, arouses and stimulates the client, supports oxygenation, and prepares naloxone, the opioid antagonist that reverses respiratory depression. Encouraging the client to press the PCA button is dangerous because it would deliver more opioid to an already oversedated client and worsen the respiratory depression. Continuing routine monitoring and waiting an hour is unsafe: respiratory depression can progress to apnea quickly, and delayed intervention risks arrest. Having a family member press the button is never acceptable; PCA is designed so that only the client presses it. This built-in safety feature works because an oversedated client cannot press the button, which prevents overdose. 'PCA by proxy,' when family or staff press for the client, defeats this safeguard and has caused fatal overdoses. Clinical pearl: monitor the sedation level, not just the respiratory rate, because rising sedation is the earliest warning. Naloxone may need repeat dosing since its duration is shorter than that of many opioids, so continue to monitor after reversal.
Question 5 · Addiction Terminology
A client with metastatic cancer has needed progressively higher opioid doses over months to achieve the same relief and develops sweating, agitation, and cramping when a scheduled dose is delayed. The client takes the medication exactly as prescribed. These findings best describe which phenomena?
- A Addiction (opioid use disorder)
- B Pseudoaddiction and drug-seeking behavior
- C Tolerance and physical dependence
- D Drug diversion to another person
Show answer & rationale
Correct answer: C
Tolerance and physical dependence is correct. Tolerance is the need for increasing doses to achieve the same effect, which explains the progressively higher opioid requirement. Physical dependence is a normal, expected physiologic adaptation in which abrupt dose reduction or a missed dose produces withdrawal symptoms such as sweating, agitation, and cramping. Both are predictable pharmacologic responses to chronic opioid therapy and are not signs of addiction. Addiction (opioid use disorder) is wrong because it is a psychological, compulsive pattern of drug use despite harm, with loss of control and craving; this client uses the medication exactly as prescribed for a legitimate medical reason. Pseudoaddiction is wrong because it describes drug-seeking behavior caused by undertreated pain that resolves once pain is adequately controlled; this client's pain is being treated and the findings are physiologic, not behavioral. Drug diversion to another person is wrong because there is no indication the client is redirecting medication for illegitimate use. Memory aid: tolerance means 'need more,' dependence means 'withdrawal if stopped,' addiction means 'compulsive use despite harm,' and pseudoaddiction means 'seeking relief because pain is undertreated.' Current standards stress that tolerance and physical dependence are expected in chronic opioid therapy and must never be mistaken for addiction, because that mistake leads to undertreatment of legitimate pain such as cancer pain. When opioids are stopped, they should be tapered to prevent withdrawal.
Question 6 · Opioid Side Effects
A nurse is initiating scheduled oral oxycodone for a client with chronic pain. Which expected opioid side effect requires a prophylactic management plan because it does not improve as the client develops tolerance?
- A Nausea and vomiting
- B Pruritus (itching)
- C Sedation
- D Constipation
Show answer & rationale
Correct answer: D
Constipation is correct. Opioid-induced constipation results from decreased GI motility and increased sphincter tone, and unlike most other opioid side effects, it persists for the entire duration of therapy because the client does not develop tolerance to this effect. For that reason nurses start a prophylactic bowel regimen (typically a stimulant laxative such as senna, often with a stool softener, plus adequate fluids and activity) at the same time the opioid begins, rather than waiting for constipation to occur. Nausea and vomiting are wrong as the answer because opioid-related nausea and vomiting usually subside within a few days as tolerance develops, though an antiemetic can be used temporarily. Pruritus is wrong for the same reason: opioid-induced itching commonly diminishes over time and is managed symptomatically if needed. Sedation is wrong because tolerance to sedation generally develops within days as well; however, sedation still warrants monitoring early on because it precedes respiratory depression. Clinical pearl: for opioids, tolerance develops to almost everything except constipation and pupillary miosis. Always pair a scheduled opioid with a bowel regimen from day one. Failing to do so is a frequent cause of severe constipation, impaction, and unnecessary suffering. Current standards support proactive, scheduled bowel care rather than reactive treatment.
Question 7 · Special Populations
An adolescent admitted with a sickle cell vaso-occlusive crisis rates the pain 9 out of 10 and requests the prescribed opioid. Vital signs are near baseline. Which action by the nurse is most appropriate?
- A Administer the prescribed opioid without delay
- B Delay the medication out of concern for future addiction
- C Suggest the pain rating may be exaggerated to obtain medication
- D Give acetaminophen only and reassess in 2 hours
Show answer & rationale
Correct answer: A
Administering the prescribed opioid without delay is correct, and the pain should be treated aggressively. Sickle cell vaso-occlusive crises produce severe, genuine pain from ischemia, and the standard of care is timely, aggressive analgesia, often with opioids, along with hydration and other supportive measures. Near-baseline vital signs do not indicate mild pain; clients with recurrent crises often have adapted autonomic responses, so believe the self-report of 9 out of 10 and treat it. Delaying medication out of concern for addiction is wrong and reflects a harmful bias; withholding indicated opioids for acute crisis pain causes needless suffering, and physical dependence from legitimate treatment is not addiction. Suggesting the rating is exaggerated to obtain drugs is wrong and reflects stigma that disproportionately harms sickle cell clients; repeatedly undertreating their pain can actually drive pseudoaddiction, in which the client escalates requests because the pain is undertreated. Giving acetaminophen only for 9 out of 10 crisis pain is inadequate and does not match the WHO ladder principle that moderate-to-severe pain warrants a strong opioid. Clinical pearl: believe and aggressively treat sickle cell and cancer pain; these are populations most often undertreated because of bias and misjudged vital signs. Rapid, adequate analgesia is both compassionate and evidence based.
Question 8 · Opioid Safety (SATA)
A nurse is teaching a client and family about a newly started IV opioid PCA for postoperative pain. Which statements should the nurse include? Select all that apply.
- A Family members may press the button while the client is sleeping
- B Only the client should press the PCA button
- C The nurse will monitor the client's sedation level and respiratory rate
- D Constipation will resolve on its own as the client develops tolerance
- E Naloxone can reverse opioid-induced respiratory depression if needed
- F A prophylactic bowel regimen will be started to prevent constipation
Show answer & rationale
Correct answer: B, C, E, F
Teaching that only the client should press the PCA button is correct: the client-only design is a key safety feature, because an oversedated client cannot press the button, which helps prevent overdose. Starting a prophylactic bowel regimen is correct, because opioid-induced constipation is expected and does not improve with tolerance, so proactive laxative therapy is standard. Monitoring the sedation level and respiratory rate is correct, because sedation precedes respiratory depression and is the earliest warning sign of opioid toxicity. Teaching that naloxone can reverse opioid-induced respiratory depression is correct, since naloxone is the opioid antagonist used for reversal. Telling the family they may press the button while the client sleeps is incorrect and dangerous; this is 'PCA by proxy,' which bypasses the built-in safety mechanism and has caused fatal overdoses. Stating that constipation will resolve on its own with tolerance is incorrect, because unlike nausea, sedation, and pruritus, constipation persists throughout opioid therapy and requires ongoing management. Clinical pearl: PCA is client-controlled analgesia, emphasis on client. Reinforce with the family that helping by pressing the button is never safe, and their role is to alert the nurse if the client seems overly sleepy or hard to wake. Combine these safety points with sedation-focused monitoring for the best outcomes.
Question 9 · Pain Assessment (SATA)
Which statements reflect accurate principles of pain assessment that a nurse should apply in practice? Select all that apply.
- A The absence of grimacing means the client is not in pain
- B In chronic pain, vital signs often normalize despite ongoing pain
- C Pain is whatever the client says it is, existing whenever the client says it does
- D Behavioral and observational scales are used when self-report is not possible
- E Normal vital signs confirm that a client is not experiencing pain
- F Self-report is the single most reliable indicator of pain
Show answer & rationale
Correct answer: B, C, D, F
The statement that pain is whatever the client says it is, existing whenever the client says it does, is correct; this classic principle directs nurses to accept and act on the client's report. Recognizing that in chronic pain vital signs often normalize despite ongoing pain is correct, because the autonomic system adapts over time, so stable vitals do not rule out significant pain. Stating that self-report is the single most reliable indicator of pain is correct and is the foundation of assessment. Using behavioral and observational scales (such as FLACC or PAINAD) when self-report is not possible is correct; these tools are reserved for populations who cannot verbalize pain, like infants or clients with advanced dementia. Saying that normal vital signs confirm a client is not in pain is incorrect, because pain can exist with completely normal vital signs, especially in chronic pain. Saying that the absence of grimacing means no pain is incorrect, because clients may control facial expression, be distracted, or have adapted behaviorally while still experiencing severe pain. Clinical pearl: never override a client's self-report with your interpretation of their appearance or monitor readings. Objective cues supplement the assessment and become primary only when a client is unable to self-report. Undertreatment most often stems from clinicians trusting behavior and vital signs over the client's own words.
Question 10 · Pain Scale Selection (SATA)
A nurse is selecting appropriate pain assessment tools for several clients. Which of the following are correct matches of tool to client? Select all that apply.
- A Use a numeric 0-to-10 scale for an alert adult who can self-report
- B Use a numeric 0-to-10 scale for an unconscious adult
- C Use the PAINAD scale for a client with advanced dementia
- D Use the FLACC scale for a nonverbal 4-month-old infant
- E Use behavioral observation only when the client is able to self-report
- F Use the Wong-Baker FACES scale for an alert 4-year-old child
Show answer & rationale
Correct answer: A, C, D, F
Using the FLACC scale for a nonverbal 4-month-old infant is correct, because FLACC (Face, Legs, Activity, Cry, Consolability) is a behavioral tool validated for infants and nonverbal children. Using the PAINAD scale for a client with advanced dementia is correct, because PAINAD is an observational tool designed for adults who cannot self-report due to advanced dementia. Using the Wong-Baker FACES scale for an alert 4-year-old is correct, because FACES suits young children (about age 3 and older) and others with verbal difficulty who can point to the face matching their pain. Using a numeric 0-to-10 scale for an alert adult who can self-report is correct and is the preferred tool for that population. Using a numeric 0-to-10 scale for an unconscious adult is incorrect, because a numeric scale requires the ability to understand and report a number; an unconscious client cannot self-report, so a behavioral assessment and physiologic cues must be used instead. Stating that behavioral observation should be used only when the client is able to self-report is incorrect and backwards; behavioral and observational methods are reserved for when self-report is not possible. Memory aid: self-report is always first-line when the client can provide it; match the alternative tool to the population's developmental and cognitive ability, and reserve behavioral scales for clients who cannot self-report.

Pain Management FAQ
What is the most reliable indicator of a client's pain on the NCLEX?
The client's own self-report is the single most reliable indicator of pain. The rule to memorize is that pain is whatever the client says it is, existing whenever the client says it does. Believe the client even when vital signs are normal and the client is not grimacing, because in chronic pain the body adapts and objective signs often disappear. Use behavioral scales only when the client cannot self-report.
How do I choose the right pain scale for a patient?
Match the tool to the population. Use a numeric 0-to-10 scale for adults who can self-report, the Wong-Baker FACES scale for young children about age 3 and older or people with verbal difficulty, the FLACC scale for infants and nonverbal children, and the PAINAD scale for clients with advanced dementia. Self-report is always preferred; reserve behavioral and observational scales for clients who cannot verbally report their pain.
What is the difference between tolerance, dependence, and addiction?
Tolerance means needing a higher dose to get the same effect. Physical dependence means withdrawal symptoms occur if the drug is stopped abruptly; it is an expected physiologic response, not addiction. Addiction is compulsive use despite harm, a psychological disorder. Pseudoaddiction is drug-seeking behavior caused by undertreated pain that resolves once the pain is adequately controlled. Do not undertreat pain out of unfounded fear of addiction.
Why is opioid-induced constipation treated differently from other side effects?
Constipation is the one common opioid side effect that does not improve as the client develops tolerance, so it must be managed proactively for the entire course of therapy. Start a prophylactic bowel regimen, usually a stimulant laxative such as senna with adequate fluids and activity, when the opioid begins. Other effects like nausea, sedation, and itching typically subside within a few days as tolerance develops.
