Select the assessment finding that requires immediate follow-up by the nurse.

An oxygen saturation level of 88% is a critical finding that necessitates immediate follow-up by the nurse. Normal oxygen saturation levels typically range from 95% to 100%. A reading of 88% indicates significant hypoxemia, which can lead to inadequate oxygen delivery to tissues and organs. This level of oxygen saturation suggests that the patient may be experiencing respiratory distress or other serious conditions that could rapidly deteriorate if not addressed promptly.

In contrast, while a blood pressure of 168/101 is elevated and may warrant further observation and intervention, it does not require the same level of immediate action as low oxygen saturation. A heart rate of 95 beats per minute, although slightly elevated, is generally considered acceptable in many clinical contexts and does not signal an immediate threat. Likewise, a temperature of 100.5°F may indicate a mild fever or infection, but it is not an urgent finding compared to a critically low oxygen saturation level that can quickly affect the patient's overall well-being.
