Which statement about Explain Pain concepts is NOT true?

• A. Pain is an output of the brain.
• B. Hurt is not harm.
• C. Pain is a direct measure of tissue damage.
• D. Pain is influenced by biological, psychological, and social factors.

Answer: (C)

Pain is not a direct readout of tissue damage; in Explain Pain, pain is the brain’s output, produced after the brain evaluates threat from multiple sources. Tissue damage can contribute to pain, but it is not a reliable gauge of how injured the tissue truly is. The brain integrates nociceptive signals with biological, psychological, and social information, so pain can be amplified or dampened by factors such as attention, mood, beliefs, past experiences, and the surrounding environment. You can experience significant pain with relatively little tissue damage, or have substantial tissue damage with little or no pain, illustrating that pain does not linearly reflect tissue injury. The idea that pain is an output influenced by these factors fits the Explain Pain approach, whereas the statement claiming pain directly measures tissue damage does not. Hurt is not harm, and pain is shaped by biological, psychological, and social influences, reinforcing why the direct-tissue-damage view is not true.
