Which of the following is an example of objective information?

Objective information refers to data that can be observed or measured, as opposed to subjective information, which is based on personal opinions, interpretations, feelings, or statements made by individuals. The correct answer presents a clear and factual description that can be seen or verified by others.

In this case, stating that "there are raised, red marks the size of pinpricks on Mrs. Johnson's torso" provides specific visual details about her condition that are not influenced by personal feelings or interpretations. This type of information can be observed directly, allowing for accurate assessment and documentation.

On the other hand, the other choices illustrate subjective interpretations or individual perspectives. For example, a statement about what Mrs. Johnson claims to have or how she feels conveys her personal experience but does not offer objectively measurable details. Similarly, suggesting that Mrs. Johnson "must have a rash" is an assumption based on her appearance, rather than an observed detail. Lastly, stating a need for lotion shows a preference or recommendation rather than an observable physical fact, which further emphasizes the need for clarity in distinguishing between observation and inference.
