Which statement best describes how infants experience pain relative to older children and adults?

• A. Infants perceive and react to pain similarly to older children and adults.
• B. Infants feel pain less than older children.
• C. Infants never feel pain.
• D. Infants cannot localize pain.

Answer: (A)

Infants process and respond to pain in ways that show they truly experience it, similar in kind to older children and adults. By the late gestational period and after birth, the pathways that detect noxious stimuli are functional, and newborns exhibit clear responses to pain—crying, facial grimacing, body movements, and changes in heart rate and oxygen levels. They may not be able to describe the sensation, but their behavioral and physiologic reactions indicate real perception and distress. This is why pain assessment in infants relies on observing these cues and providing appropriate analgesia, rather than assuming they are unaffected by painful stimuli. The other statements don’t fit because infants do feel pain, they do react to it, and while their localization of pain is less precise due to immature neurodevelopment, they still demonstrate awareness and distress in response to pain.
