A physical examination is a fundamental clinical procedure used to assess a patient's overall physical health status through systematic observation. The process involves several key components, including visual inspection of the integumentary system and surrounding structures; palpation, which is the assessment of the body using touch to evaluate tissue texture and measure organ size; auscultation, which involves listening to internal sounds using a stethoscope to evaluate cardiovascular, pulmonary, and gastrointestinal function; and percussion, which assesses underlying structures by tapping over an area. The findings gathered from these standardized methods assist in the preliminary detection of physiological abnormalities, guiding further diagnostic testing and informing the overall treatment plan.
