In the case of a suspected heart attack, what is the nurse's priority action?

In the case of a suspected heart attack, the priority action for the nurse is to call for emergency medical assistance. This step ensures that the patient receives prompt medical intervention, which is critical in managing a heart attack. Time is of the essence in such situations, as every moment can significantly affect the patient’s outcomes.

Calling for emergency help allows trained medical personnel to arrive with necessary equipment and medications, potentially saving the patient's life. The rapid response includes advanced cardiopulmonary resuscitation (CPR) protocols if the patient is unresponsive or not breathing, as well as access to defibrillation and emergency medications.

While assessing vital signs and administering intravenous fluids are important components of patient care, they can occur once emergency assistance has been summoned. The first and most immediate step is to ensure that higher-level care is on the way.
