Step-by-step explanation:
Subjective data in information gathering from the patient refers to information that is based on the patient's own perceptions and experiences. It cannot be clinically confirmed or objectively measured. Pain is an example of subjective data because it is based on the patient's own description and cannot be measured directly.
