How should a nurse respond if a patient experiences chest pain during the administration of nitroprusside?

When a patient experiences chest pain during the administration of nitroprusside, the appropriate response is to administer oxygen and assess vital signs. This is critical because chest pain could indicate potential complications, such as myocardial ischemia or hypotension, particularly given that nitroprusside is a potent vasodilator that can significantly lower blood pressure. Administering oxygen ensures that the patient receives adequate oxygenation, which is essential for heart tissue, especially if it is not receiving sufficient blood flow.

Assessing vital signs is also crucial in this context as it helps the nurse monitor for any significant changes in blood pressure, heart rate, or rhythm that may require immediate intervention. This approach prioritizes patient safety and provides necessary data to inform subsequent actions, ensuring that the nurse can respond effectively and promptly to any worsening condition.

In contrast, documenting the event while continuing the infusion would overlook the patient's immediate need for assessment and intervention. Increasing the infusion rate could exacerbate hypotension and worsen the situation. Switching medications without proper evaluation could lead to delays in addressing the underlying issue causing the chest pain.
