Which of the following represents objective data?

Objective data refers to information that is measurable, observable, and can be verified through examination or testing. In the context of the options provided, a temperature reading of 102° F is a specific measurement that can be objectively assessed using a thermometer, making it a clear example of objective data. This type of data does not rely on personal feelings or perceptions but is based on factual, quantifiable evidence.

The other options, such as the patient's report of feeling chills or the description of having a fever, are subjective findings. They rely on the patient's personal experience or interpretation of their symptoms rather than measurable criteria. Therefore, while they can inform a nurse's assessment, they do not meet the criteria for objective data. The mention of an elevated temperature could imply an increase above a normal baseline but is still less precise than stating an exact temperature, which is why it does not represent objective data as clearly as the specific measurement does.
