Final answer:
The nurse should treat the patient's elevated temperature, heart rate, breathing rate, and low blood pressure as signs of a possible systemic infection like sepsis and initiate immediate medical interventions such as IV fluids and antibiotics, while continuously monitoring vital signs.
Step-by-step explanation:
Given the patient's vital signs of high temperature (102 °F), elevated heart rate (120 bpm), increased breathing rate (25 per minute), and low blood pressure (90/60), the nurse should consider these changes indicative of a serious condition, possibly sepsis.
Although the blood test results are pending, the nurse should act swiftly due to the signs of a systemic infection. Immediate medical intervention, including administration of intravenous fluids and potentially broad-spectrum antibiotics, should be initiated following hospital protocols, and continuous monitoring of the vital signs is essential.
Consultation with a physician to evaluate the need for further medication, such as antipyretics to manage fever, or oxygen supplementation, might also be necessary.
