What is the difference between a heart attack and cardiac arrest? How do you determine if a bandage is too tight on the arm of an unresponsive victim?
When shock occurs, how does the body prioritize the need for blood?, why?

Each question needs to be 3+ sentences

Examine the wrapped area for any discoloration of the toes, fingers or arm beyond bruising from the initial injury. An overly tight bandage can compress the skin to create a blue or purple tinge to the skin. Assess how the injured body part feels. If you feel tingling, buzzing or numbness, the bandage is wound too tight. As blood pressure drops during cardiogenic shock, the body tries to compensate by limiting blood flow to the extremities—the hands and feet—causing them to cool down. As blood flow to the brain drops, the person may become confused or lose consciousness.
