If a patient would ask the nurse why he/she is experiencing pain, it is best to tell the patient that chest pain or any discomfort in the arm, shoulder, neck, or back is caused by the decrease of blood flow to heart. Add to that, the nurse may inform the patient that people experiencing heart attacks may also feel shortness of breath, along with sweating, weakness, nausea, and fatigue.
