A patient with leukemia shows low blood pressure. What should be the priority nursing action?

In the context of a patient with leukemia who presents with low blood pressure, the priority nursing action is to administer IV fluids as prescribed. Low blood pressure can indicate hypovolemia, dehydration, or a potential septic state, especially in patients with leukemia who may have impaired immune function and an increased risk for infections. Administering IV fluids is a critical intervention to help restore blood volume, improve circulation, and stabilize blood pressure.

While monitoring the patient’s temperature and reassessing pain levels are important components of overall patient care, in this scenario, they do not directly address the immediate threat to the patient's hemodynamic stability. Checking for signs of bleeding is also relevant, given the risk factors associated with leukemia, but the priority remains to manage the low blood pressure through IV fluid administration. This action can have a rapid effect on improving the patient’s condition and preventing further complications.
