Which is NOT a sign of shock?

High blood pressure is not a sign of shock. In cases of shock, the body experiences a decrease in blood pressure due to inadequate circulation and reduced blood volume, which happens as the body struggles to maintain adequate blood flow to vital organs. The physiological response to shock often includes responses such as increased heart rate and weakened pulses, along with changes to the skin's condition (like being cold and clammy or pale) as blood is redirected from the body's extremities to maintain perfusion to the brain and vital organs. Therefore, the manifestation of high blood pressure contradicts the condition of shock and is considered an incorrect answer in this context.
