Which of the following is an example of objective information?

Objective information refers to data that can be observed, measured, or verified through senses or instruments, which provides a concrete basis for assessment. In this case, the statement that "Mrs. Smith fell on the floor" is an example of objective information because it describes an observable event that can be confirmed by anyone who witnesses it or by evidence such as physical marks, location, or witness accounts. This type of information is critical in health care as it informs practitioners about the patient's condition without relying on personal feelings or perceptions.

The other statements reflect subjective information that is based on personal feelings or perceptions. For instance, stating that "Mrs. Smith feels dizzy," "Mrs. Smith thinks she is improving," or "Mrs. Smith says she is in pain" relies on Mrs. Smith's personal experiences and interpretations of her condition. While these insights are important for overall care, they do not provide the measurable data that objective information does. Hence, "Mrs. Smith fell on the floor" is the only fully objective piece of information among the choices, making it the correct answer.
