Which option correctly presents the PQRSTU pain assessment mnemonic?

• A. Pain, Quality, Region, Severity, Timing, Understanding
• B. Provocation, Quality, Radiation, Severity, Timing, Understanding
• C. Provocation/palliation, Quality, Region/Radiation, Severity, Timing, Understanding/Impact
• D. Prevention, Quality, Radius, Severity, Time, Understanding

Answer: (C)

The main idea is to gather pain information in a structured, comprehensive way by focusing on six key aspects. Provocation/palliation asks what triggers the pain and what relieves it—this helps you understand factors that worsen or ease symptoms and guides treatment decisions. Quality describes the character of the pain—whether it feels sharp, dull, burning, or throbbing—information that can point toward different causes and interventions. Region/Radiation covers where the pain is located and whether it radiates to other areas, which helps in localizing issues and recognizing nerve involvement. Severity uses a numeric or descriptive scale to quantify how intense the pain is, essential for monitoring changes and evaluating treatment effectiveness. Timing looks at when the pain started, how long it lasts, and how often it occurs, capturing patterns that influence management. Understanding/Impact assesses how pain affects daily activities, mood, sleep, and function, and it also includes the patient’s own understanding of their pain, which is crucial for patient-centered care.

The best option lists Provocation/palliation, Quality, Region/Radiation, Severity, Timing, and Understanding/Impact, aligning with standard pain assessment practice and including both what provokes and what relieves pain, the exact location and spread, the pain’s intensity, its temporal pattern, and its impact on the patient. Other options mix in terms that aren’t part of this framework (such as Radius or Prevention), omit palliation or impact, or use wording that doesn’t match the established mnemonic, making them less complete for a thorough assessment.
