Why might a patient with a full-thickness burn report little or no pain?

• A. Nerves have been burnt
• B. Pain is delayed
• C. Adrenaline blocks pain
• D. The burn is superficial

Answer: (A)

In a full-thickness burn, all layers of skin, including the nerve endings, are destroyed. Without intact nerves to transmit pain signals, the area can feel little or no pain despite the severity of tissue damage. This is why a person with a full-thickness burn may report reduced sensation even though the burn is extensive. Pain is more likely to be felt in burns where nerves are still intact (superficial or partial-thickness), because those nerve endings can transmit pain. The idea that pain is always delayed isn’t the best explanation here, since the key factor is nerve destruction. Adrenaline blocks pain is not the mechanism at play, and describing the burn as superficial is incorrect for full-thickness burns.
