Baseline data is typically collected during the initial patient assessment. This process involves: - Interviewing the Patient: Gathering subjective data through questions about symptoms, medical history, and lifestyle. - Physical Examination: Recording objective data such as vital signs (temperature, pulse, respiration rate, and blood pressure), height, and weight. - Diagnostic Tests: Collecting data from laboratory tests, imaging studies, and other diagnostic procedures. - Reviewing Medical Records: Obtaining past medical history, previous treatments, and other relevant information from existing records.
