What is NOT a sign of shock in an infant?

In the context of assessing an infant for signs of shock, increased appetite would not be consistent with this life-threatening condition. Shock typically results in decreased perfusion to vital organs, leading to the infant demonstrating signs of distress rather than an increased desire to feed.

In contrast, signs of shock in infants include cool, pale, clammy skin due to vasoconstriction and reduced blood flow to the skin; rapid and shallow breathing as the body attempts to compensate for decreased oxygen delivery; and a weak or rapid pulse indicating inadequate circulation and a body under stress. These physiological responses are crucial indicators that a medical professional must recognize to intervene appropriately.
