Final answer:
Signs and symptoms that would make the nurse suspect an MI include crushing chest pain, diaphoresis (sweating), and cool clammy skin.
Step-by-step explanation:
In the case of acute MI, there is often crushing chest pain beneath the sternum, called angina pectoris, which may radiate down the left arm. Other signs and symptoms that would make the nurse suspect a MI include diaphoresis (sweating) and cool clammy skin. It's important to note that not all symptoms may be present.
