What is an expected behavioral response to pain in a newborn aside from crying?

The expected behavioral response to pain in a newborn, aside from crying, includes a rapid heart rate. When a newborn is in pain, their autonomic nervous system responds, which can lead to physiological changes such as an increased heart rate. This change is part of the body's overall response to stress and discomfort.

Newborns may show limited ability to express their experiences verbally, so physiological changes like heart rate fluctuations are significant indicators of their pain level. Increased heart rate can also be a sign that the infant is experiencing distress or discomfort.

The other responses provided—responding to touch, exhibiting hyperactivity, and excessive sleeping—are not recognized as direct indicators of pain in newborns. Instead, newborns may have a heightened sensitivity to touch when in pain, which doesn't represent a typical response to pain. Hyperactivity is not commonly associated with pain, as pain often leads to a more subdued state in infants. Likewise, excessive sleeping would not typically reflect a response to pain, since pain usually leads to an alert state as the baby reacts to discomfort.
