Which of the following types of information is classified as subjective?

Diagnosis is an objective conclusion drawn by a healthcare professional based on clinical findings, tests, and examinations. It relies on measurable data and established medical criteria, rather than the patient's personal feelings or interpretations, thus categorizing it as an objective aspect of medical practice.

A physical examination involves objective assessments conducted by a healthcare provider, such as measuring vital signs or observing physical symptoms. The findings are based on observable and measurable criteria, distinguishing them from the subjective nature of medical history.

Progress notes are typically written by healthcare providers and include observations and clinical data regarding a patient's ongoing treatment and response. While they may contain some subjective interpretations, they primarily reflect objective assessments made during the patient's care.

Treatment refers to the medical interventions applied to address a patient's condition and is determined based on clinical guidelines and objective assessments. Though patient preferences may influence the choice of treatment, the overall approach remains grounded in objective medical practice.
