What is the correct order of priority for nursing interventions based on vital signs?

In assessing the priority of nursing interventions based on vital signs, attention is primarily directed toward those indicators that reflect immediate physiological distress and require prompt attention.

In option A, the SpO2 level is the most pressing concern, as it indicates hypoxemia (low oxygen saturation) at 89%. Normal SpO2 levels typically range from 95% to 100%, and anything below 90% necessitates urgent intervention because it can lead to tissue hypoxia. Following this concern, the respiratory rate is also critical, with a rate of 28 breaths per minute suggesting potential respiratory distress or complications, such as an increased work of breathing or hypoventilation.

Subsequently, blood pressure is elevated at 160/86, which indicates hypertension, requiring monitoring and possible intervention, but it is less immediately life-threatening compared to severely low oxygen levels. The heart rate remains stable at 72 bpm, indicating a normal pulse, and the temperature is at a normal range of 37.33°C, meaning it is not an immediate contributor to urgency.

This prioritization reflects the necessity to address the most life-threatening conditions first, thereby ensuring effective and timely patient care.
