Physical examination remains a valuable diagnostic tool despite advanced medical technology. Many diagnoses can only be made through physical examination, and findings at the bedside rarely occur without lab or imaging confirmation. By conducting history and physical together, providers generate and test hypotheses, allowing more judicious test ordering and reducing patient risk and healthcare costs.

Before every exam, wash your hands with soap and water or apply topical disinfectant solution. Disinfect exam room surfaces and equipment like stethoscopes or reflex hammers. If the patient has a known infection, obtain necessary protective equipment and ensure glove cuffs cover the gown completely to prevent skin exposure.

After introducing yourself and your role, request family members to leave the room for privacy. Draw curtains and close doors. Explain the planned exam and ask permission to proceed. Ensure proper adjustment of patient attire during the physical exam by providing a gown and drape if necessary, allowing time for the patient to change before you re-enter.

During initial conversation, observe the patient's appearance consistency with stated age, overall health, alertness, affect, thought content and organization, and perception. These observations provide important baseline information about the patient's general health status and mental status before proceeding with specific examination components.

Each exam component employs four primary techniques: inspection, percussion, palpation, and auscultation. These techniques are used systematically to assess different body systems and organs. Grouping maneuvers by position minimizes unnecessary patient repositioning and improves examination efficiency while maintaining patient comfort and dignity throughout the assessment.

Request the patient to change back into regular clothing before offering advice or opinions. This allows time for the patient to feel composed. Then, consolidate information from the patient's history and physical exam findings to decide whether to initiate therapy or order additional testing in a deliberate and judicious manner.

A chaperone may be necessary when conducting sensitive exams such as genitourinary, rectal, or breast examinations. The presence of a chaperone protects both the patient and physician by ensuring professional conduct and providing a witness during potentially sensitive procedures, promoting patient safety and trust.
